14、tric Corp.and 84 affiliates(63 domestic,21 overseas)Our Common Fate Aboard“Spaceship Earth”When the term“Spaceship Earth”was first coined over three decades ago,I was stirred by the penetrating wisdom of the concept.At that time in my career,I was directly involved in research to develop more effici

15、ent energy use,with this new expression underscoring the weight of my own personal work.With Japan at the end of the high growth period that characterized its postwar era,the nation had clearly obtained economic affluence.Yet,gazing at the dark,stagnant and putrid smelling rivers and other grim bypr

16、oducts of this progress,this was also a time of somber and repeated introspection into the viability of our approaches to the economy,technology and other sectors.Today,fish once again populate the rivers of many Japanese cities,with growing evidence that we are moving toward the resolution of local

17、 environmental issues.On the other hand,global warming and other macro-level environmental problems continue to grow in scale and complexity,prompting the inevitable conclusion that the time is now right to once again reexamine our shared journey,and common fate,as passengers aboard“Spaceship Earth.

18、”Meaningful Action and ContributionsThe Mitsubishi Electric Group,naturally,is one of the passengers on“Spaceship Earth,”with our own business activities part of the journey and the destination of the craft.Taking this understanding to heart,we have not only succeeded in supplying energy conserving

19、products,but also grown more energy efficient in all areas of our plant operations.We have developed water treatment processes through the use of ozone and other innovative technologies,in moving to reduce the impact of our activities on the ecosystem.On this front,the greatest contribution of our G

20、roup is the supply of environmental-conscious products and services for which energy efficiency has been heightened on the strength of sophisticated engineering developments,together with the vigorous creation of technologies that contribute to sound environmental solutions.Simply put,ours is the qu

47、anagement VisionIn rising to the universal challenge to forge a“sustainable society,”the Mitsubishi Electric Group believes we can make the greatest contribution by channeling the“technology,”“service”and“creativity”cultivated over the decades into“eco-products.”Simply stated,our goal is the vigorou

48、s supply of expertise and products that protect and improve the natural environment.Working from this cone environmental philosophy,we have designated“Bringing the flowers of MET to bloom”as the watchword for our eco-friendly corporate stance.By“MET,”we mean“Materials”(effective use of resources);“E

49、nergy”(efficient use of energy);and“Toxicity”(reduced use of substances potentially harmful to the environment).Through these three pivotal perspectives,we aim to steadily reduce the environmental impact of the wide-ranging business activities and products of the Mitsubishi Electric Group.To bring t

50、he“Flowers of“MET”to bloom,and harvest the rich fruits of eco-friendly technology and products,we are determined to grow the tree of environmental management straight and tall,constantly moving forward together toward a brighter,more rewarding tomorrow.Under the international principle of“sustainabl

51、e devel-opment,”the Mitsubishi Electric Group is committed to protecting and improving the global environment through all business activities and employee actions utilizing knowledge accumulated in the past as well as technologies yet to be developed.From the following page,we are pleased to introdu

62、cycling plants,there were spent consumer electronic products that had been disposed of,and we arrived at the conclusion that,“It is necessary to adopt designs that facilitate easier product dismantling.”For example,more than two-thirds of the discarded air-conditioners remained serviceable as produc

63、ts,but were dirty inside,smelled bad,performed poorly due to dirt and grime and so forth.According to the results of a certain purchase motivation survey,meanwhile,on replacement purchase demand(which accounted for 53%of the total),some 16%cited“breakdowns”as the reason for purchasing a new product.

64、The leading reason given in this category was“Dissatisfaction because the product is old,”at 24%.Specific causes of this dissatisfaction included“decline in capacity”and other reasons,often including worsened capacity resulting from dirt inside the air-conditioner unit.While,ideally,the filter shoul

65、d be cleaned once every two weeks,many customers only clean it once a season.From the customers standpoint,therefore,“eco-friendly products”refer not just to energy efficiency,but also to keep the inside of the air-conditioner itself clean.”Emerging from this perspective,therefore,was the“easy-to-cl

66、ean body”based on ease of cleaning and recycling,the“3D clean filter”to prevent dirt from getting inside the air-conditioner in the first place,the“plasma ventilation interior clean”function to automatically clean the interior after use,and other developments.These concepts are the results of focusi

67、ng our attention and expertise on the need to curb the disposal of these products.Maintaining Cleanliness to“Reduce”(Curb Disposal)Turning to our air-conditioner refrigerants,because the use of the chlorofluorocarbon R22 is destructive to the ozone layer,we have switched to the new refrigerant R410A

68、.However,because changing the refrigerant also means changing the refrigeration oil,the standard approach when making such a move is to replace the pipes as well.Leaving the oil used in the old refrigerant model inside the pipes,however,causes deterioration,clogging and other problems for the oil us

69、ed in the new refrigerant model.With our new refrigerant-use model,the existing pipes may be reused in both domestic and commercial applications.This breakthrough was made possible through the new development of refrigeration oil and other Mitsubishi Electric original“replace”technology.Reusing the

70、existing pipes plays a key role in both reducing the volume of scrap materials and curbing the consumption of new materials.With recycling,meanwhile,there are numerous issues to be addressed.For air-conditioners,the plastic in indoor units poses a problem.For example,many different types of material

71、 are used,and coating these items makes it impossible to reuse them.We are target-ing this problem by reducing the types of plastic used as much as possible,using the interlocking method and other means of reducing the number of attachment points.Proper labeling of materials is also important,and we

72、 meticulously illustrate the dismantling markingson the product(see page 20)to raise the product-recycling rate.At present,we adopt recyclable plastic materials made from our refriger-ator vegetable cases on the panels of the Kirigamine outdoor unit,and are working hard to promote recycling designs

73、that are even more effective.Reuse of Pipes and RecyclingEnergy Conservation Begins from Proposalsfor“Performance+Ease of Use”In aiming for an eco-friendly society,it is important to consider the handling of environmental-risk substances.At present,througah the strong partnerships forged with our su

81、See page 23 for details.“Kirigamine”ZR Series Room Air-ConditionerWhat is energy conservation,after all?An example is the“Double Floor Temperature Sensor.”This is a function in which two separate controlling floor temperature sensors are mounted on an indoor unit to provide comfortable airflow in ro

82、oms being used,while realizing ener-gy efficiency at the same time.The conventional approach has been to treat the temperature at the intake port as the room temperature.Now,however,with the Double Floor Temperature Sensor able todistinguish floor temperature distribution,controls are used to warm t

83、he room from the legs down during heating,while avoiding excessive chilliness during cooling.The result is energy savings of about 20%.Add area air-conditioning that only operates when necessary,and the savings climb by a further 10%.All manufacturers naturally channel efforts into raising product e

84、nergy consumption efficiency in termsof the COP(coefficient of performance).With the design of the Kirigamine,however,we are proud of taking our efforts a step be-yond,based on concern for the condition after the product is in the customers hands.In this respect,we hope that the expanded useof the c

85、urrent Kirigamine will pave the way to greater overall energy conservation.The volume of electricity used in todays products is roughly half what it was just 10 years ago,thanks in great part to the advances in inverter technology.The“Poki Poki Motor”(see page 13),a Mitsubishi Electric original used

86、 as a compressor,also contributes to this im-proved performance.Environmental Sustainability Report 2004Environmental Sustainability Report 2004We constantly strive to reducethe environmental impact of our air-conditioners throughout their entire service lives.Yoshihiro TanabeElectricity charges cut

93、4Performance F1.000 Environmental F1.141Because transformers are essentially simple machines,there has been little if any innovation in terms of principles,functions or otherfundamental points.The true proving ground for success with transfor-mers,therefore,lies in raising their energy efficiency in

94、 other words,harnessing technologies to reduce loss.In developing the EX Series,our most energy-efficient transformer,we engaged in repeated technical exchange with materials makers,with long debates over the best design.The stator core consists of a stack of electromagnetic steel plates.However,whe

95、n we divide it up into several parts and measure the magnetic flux,we find that the flux varies widely from spot to spot.To control loss,therefore,it is important to advance design considering the differences in magnetic flux at the stator core outer and the inner circumference.It is also important

96、to change the vertical and horizontal ratio(width and depth)without changing the stator core cross section.However,when the shape of the stator core is changed,there are also changes in the configuration of the coil that is wrapped around that core,with the loss generated at the coil also varying.Be

97、cause of this,it is critical to create a design that reduces the total loss.Yet,since we have not traditionally designed from that perspective,this renewed our appreciation of the importance of design analysis.Furthermore,because electromagnetic steel plate is recyclable in the same way as ordinary

98、steel,we use that steel plate as the stator core material.This material,then offers ample potential for further technological innovation.Materials and Design Cut Total Loss by 60%In this way,we chose a“magnetic domain control electromagnetic board”as the new stator core.However,when we moved into th

99、e pilot production stage,we were just unable to realize the characteristics congruent with the design.Looking for what was wrong,we found that the workplace was handling the new model in the same way as the conventional model.Hastily putting the units together resulted in bent parts being used,defor

100、mation during transport and other problems.With the new product,however,the steel plate that serves as the stator core material was around 30%thinner than the conventional version,with most of the materials being extremely delicate.A key point in this work is the degree to which stress can be remove

101、d from the assembly process.We explained this to the plant workplace to encourage workers to change their goal from quickly turning out the finished product.Instead,we taught them to“consider the importance of characteristics in handling.”I must say,though,that.Getting the workers to appreciate roug

102、h handling of this transformer detracts from its performance,and that it is simply different from the conventional model,turned out to be a series of squabbles and standoffs to say the least!(laughs).In the same light,it is also essential to gain the understanding of the customer.A transformer has a

103、 long service life,and focus needs to be placed on its overall lifecycle rather than just the initial stages.The EX Series involves much time and work,as well as special materials,so,it is not cheap.However,the energy saving effects will pay back the initial outlay of large-lot users over a period o

104、f five to 12 years,with this performance also curbing environmental impact.At Mitsubishi Electric,therefore,we prepare and tender energy-efficiency proposals tailored to the transformer use of individual customers,striving to make the anticipated fruits of energy conservation visible.Reforming the W

106、attery modulesEliminating Electrode-Protecting LeadIn photovoltaic power generation systems,most lead has tradi-tionally been used to protect the photovoltaic battery module cell electrodes.A typical module measures 1.2 by 0.8m,with a frame thickness of 37mm,and rows of 40 photovoltaic battery cells

107、 each 15cm2.The cells are made of silicon,and have electrodes using silver on the both the top and bottom.Because silver corrodes easily,the conventional approach was to use a lead solder coating to protect the electrodes.In our mission,we developed a new cell structure to enable all lead to be elim

108、inated from the battery cells.The first step was the electrode paste,for which we used a newly perfected version where forming has been improved through ongoing joint research with materials makers.The electrodes are placed atop the silicone cells,and because the 300m thickness of the cells makes th

109、em prone to breakage,they are protected with a layer of EVA(ethylene vinyl acetate).EVA is an excellent shock absorption material that is also lightweight and very resilient.In addition,while the cell surface(the side opposite the glass)was conventionally back coated with the fluororesin PVF(polyvin

110、yl fluoride)film,we adopted the dual structure of PVF+PET(polyethylene terephthalate)to complement the move to lead-free with enhanced moisture resistance.Performance that Stands up to Extended UseEven with these design changes,it remains relatively simple to obtain initial use functions equivalent

111、to those of conventional products.However,assessing whether the same level of performance will be achieved 25 or 30 years down the road is not nearly as easy.This led us to the question of how to fulfill the extended accountability now demanded of photovoltaic battery modules.Beginning from the esta

112、blishment of the actual evaluation method,we carried out a rigorous testing schedule that required two-to three-fold the time devoted to JIS-standard testing.Because the module itself is too large,the testing was conducted on individual parts.Examples of this process include a heat shock test,in whi

113、ch surrounding environments of 40C and+100C were used at 30-minute intervals,at repetitions of 200 cycles.Another example is a water immersion test,in which the components were submerged in water of 80C for two hours.The new-structure cells using the new electrode paste passed these and other tests

114、with flying colors,with cost problems resolved and the products finally emerging in completed form.Development of this alternative method required a full year in all.Because the photovoltaic battery cell is capable of making a stellar environmental contribution,our top priority lies in vigorously pu

115、rsuring basic functions in the design process.Although the conversion efficiency fails to increase in direct proportion to the time and effort involved in this work,my goal is to continue improving the functions of photovoltaic battery modules.ENGLISH 04.7.12 5:13 PM 11Downsizing the Control Panel i

119、rsFor our eco-friendly elevator design,we started out by reducing the amount of vinyl chloride resin.Now,there are no parts on the standard model where the use of vinyl chloride is visible.Vinyl chloride used to be used on the walls,floors and ceilings,but this has been largely switched to polyester

120、 resin and acrylic resin.We arealso moving to reduce the environmental impact of the painting process.At the Inazawa Works,there is a large painting line that ranks as one of a kind throughout the entire Mitsubishi Electric Group.With elevators demanding bright,eye-catching finishings,the trend has

121、been to make heavy use of solvent-based paints with excellent color development.However,the toluene and other substances contained in solvents consist of volatile organic compounds(VOC)that contaminate the air,cause sick house syndrome and other problems.As such,they demand effective countermeasures

122、.From the outset,we constructed a panel painting line using electrostatic paint(noted for its high transfer efficiency),and have adopted other ideas to cope with this problem.We will continue to advance other measures as well,among them:(1)Eliminating the use of door panels with surfaces that requir

123、e painting;(2)changing door reinforcing materials from welding to adhesion,eliminating the thick coats of paint required to repair welding warps;(3)conversion to VOC-free,water-based paint,and other steps aimed to slash the volume of solvent paint used.While the current conversion rate to water-base

124、d paint is about 10%,with the focus on undercoats,our current schedule is to shift to water-based paints for the finishing coats as well over the next two years.For the chemical substance potentially harmful to the environment,we have completed our response for the design components,and are now adva

125、ncing an effective approach for mechanical componentsas well.For example,we are steadily moving towards the use of materials that do not generate harmful gases when incinerated or cause lead elution following disposal,in addressing this challenge on all fronts as soon as possible.In terms of drive s

126、ystems,elevators may be broadly divided into roping and hydraulic systems.With the roping system,traction mtors are used to move the elevator car up and down.At Mitsubishi Electric,we aimed for energy conservation from early on.From the standard spec“ELEPAQ”marketed in 1998,we have used the per-mane

127、nt magnet(PM)synchronized motor gearless traction machine.The ELEPAQ traction motors is a pit-installed version.With the ELEPAQ-i marketed three years later,the depth of the pit was reduced by installing a slim traction motor with equipment thickness of only 187mm(or one-fifth the previous model)in

128、the space between the elevator shaft wall and the car.Then,in 2003,we completed the worlds slimmest PM gearless traction motor,only 159mm thick.In fact,the development goal at that time was to lower the thickness to below 160mm.At the prototype development stage,we actually succeeded in pushing the

129、width down to 155mm.At the evaluation stage,however,we found ourselves locked in a tough struggle to shave thickness,one millimeter at a time.For example,we would add an inspection port,and then subject the unit to strength analysis.The weakened portion would be reinforced,which naturally increased

130、the thickness.The next step was to carefully take off that portion,one millimeter at a time,being careful to remain within the range needed to satisfy the strength specs.This slim traction motor was made possible by the“Poki PokMotor”stator production technology,an exclusive breakthrough from Mitsub

131、ishi Electric.In terms of lowering environmental impact,the shift using control inverters from the 1980s made a solid contribution.In recent years,however,important sources of progress have inclu-ded improved energy efficiency through the use of the aforemen-tioned PM motor-type gearless traction ma

132、chine,as well as slimming based on weight reduction.For instance,a 3.7kW-type traction motor was lightened from 450 to 300kg and then further to 230kg.This was yet another step in saving resources.Curbing Use and Emissions of Environmental-Risk SubstancesFor the elevator control panel,“lead-free and

133、 chrome-free,”is the target and we are currently striving to achieve lead-free soldering.Besides the control panel itself,we have also changed the fixing method at both sides of the car suspension ropes(shifting from the Babbitt method of using lead to embed the wire to a caulking approach),and intr

134、oduced other improvements.Removing the machine room from an elevator enables downsizing of the various machine components,while the reduced installation space likewise contributes to resource conservation.It goes without saying,therefore,that lighter weight machinery also reduces the amount of drive

135、 energy used.On models before the ELEPAQ(marketed in 1998),the control panel was installed in the machine room at the top of the shaft.This allowed a panel width of 700mm,a depth of 400mm and a height of 1,400mm.No machine room means that the control panel must be sandwiched into the space between t

136、he shaft wall and the elevator car.The thickness(depth),therefore,can beno more than 100mm.We commenced development with this goal,but soon after read in a rival manufacturers product catalog abouta control panel of“only 100mm thick.”That motivated us,and we quickly moved to change the design of the

137、 elevator car itself,working to build a control panel box even slimmer than that of our competitor.Our specific goal was a box of only 87mm in width.To begin,we probed the existing problems.It soon became clear that the power supply containing a large transformer and an inverter that is,the system u

138、sed to adjust the voltage and frequency to ensure smooth operation was taking up considerable space.We replaced the transformer with a switching power-supply technology based on a semiconductor device,while adopting a slim inverter at the same time.We packaged both systems into an integrated power u

139、nit.This facilitated a unified cooling response to the heat generated by the switching,and we also improved the cooling efficiency with an air duct design that introduced air from in front of the control panel and flushed out waste heat at the front.In this way,we realized our goal of 87mm thickness

140、.Further improvements have followed,with the cubic volume of the control panel on the current ELEPAQ-i(marketed in 2001)only 23%,or less than one-fourth,compared to when a machine room was used.This made a big contribution on the resource savings front.However,we could not afford to simply downsize.

141、With maintenance ease ranking as another key concern,we also needed to overcome the stiff challenge of realizing high-density packaging that puts the needs of maintenance engineers foremost.Environmental Sustainability Report 2004Environmental Sustainability Report 2004Products BusinessCreating Eco-

166、for the purpose of addressing issues rela-ted to preserving the global environment utilizing a systematic means from mid-and long-term points of view.Since the intro-duction of the first plan,we have worked to construct a solid foundation for our envir-onmental management systems and main-tained our

167、 commitment to developing tech-nologies and products that contribute to the reduction of negative environmental impact.The 3rd Environmental Plan ended with the closing of fiscal 2002,and we initi-ated the activities of the 4th Environmental Plan from April 2003.With this new plan,we will focus on m

168、ore actively promoting existing activities,creating new busines-ses related to energy solutions and recy-cling,giving careful consideration to the negative environmental impact of our products throughout the entire lifecycle,and providing more information regarding our activities to society,all for

169、the purpose of contributing to the actualization of a sustainable society.The 4th Environmental Plan sets out four objectives to be attained.Previously existing are the objectives of“improving eco-efficiency”and“enhancing risk man-agement”,and newly added are“deeply integrating and internalizing man

170、agement”and“contributing to the company and busi-ness results and improving brand value.”We have identified three basic items re-quired to achieve the objectives.Setting a goal of fiscal 2005 to achieve the objec-tives,the Mitsubishi Electric Group will set targets that can be measured tangibly.In-t

223、 stay abreast of the costs involved in preserving the environment.In fiscal 2003,total environmental protection spending by Mitsubishi Electric and 45 of its subsidiaries in Japan and abroad came to 13.6 billion yen.The fruits of these outlays,meanwhile,include reduced emissions of carbon dioxide an

224、d other chemical substances,along with improvements in other fronts areas(see the chart on page 18).The real effects,meanwhile,of electricity fee savings from improvement in plant equipment control,reduced water rates thanks to water recovery and reuse,and profits from sales of scrap metal accompany

225、ing the recycling of waste and other materials came to 5.7 billion yen.Of the economic effects(estimated impact)of eco-friendly products and services introduced from fiscal 2003,customer-level economic effects were 43.3 billion yen,while environmental improvement effects were tracked at 2.2 billion

226、yen.Eco-Friendly Product and Service Effects of 45.5 Billion YenThe effects of eco-friendly products and services will be calculated for a wide range of products and services,to vigorously promoto environmental friendliness in group business activities.With regard to the internal contribution effect

227、s of“risk evasion”and other areas,studies will be used to introduce calculation standards more objectively,to prevent individual differences when quantifying those effects.This stance also encompasses efforts to ascertain the monetary value of environmental protection effects(currently expressed in

228、material quantities),the contributions to Mitsubishi Electric Group sales and profits(an impact area not yet monitored in terms of effect)and other clarification of the situation.The designation of these and other effects in financial terms will shed light on the priority ranking of specific environ

229、mental policy measures,the impact of environmental protection activities on the groups business and other information.This,we are confident,will raise motivation to engage in environmental protection.Setting Estimated Effect Calculation Standards,Other BenchmarksRecent years have seen a sharp increa

230、se in environmental protection activities,including those whose real effects(advancing the prevention of future pollution,product and service environ-mental considerations,education to promote those efforts,etc.),are difficult to grasp.To express the total value of these and other activities,and the

231、reby shed light on the specific effects of environmental programs,in August 2003 the Mitsubishi Electric Group established its“Environmental Accounting Study Panel.”This panel met and set definitions for the estimated effects of environ-mental protection activities,as well as the methods,standards a

232、nd other yardsticks used to calculate these effects.The effects of environmental considerations in products were calculated by comparison with the same models of the previous fiscal year.Likewise,the impact of such considerations adopted in services was monitored by comparing the conditions prior to

241、 2004The Mitsubishi Electric Group sets its sights on building products that improve eco-efficiency.We are mobilizing the“MET”benchmarks to reduce environmental impact throughout the product lifecycle,and raising the ratio of“Eco-Products”to over 70%by the end of fiscal 2005.Eco-Products and Design

242、for EnvironmentEnvironmental Substainability Report 2004The Mitsubishi Electric concept of“Eco-Products”consists of steadily enhancing the ease of use and function that are the essential value of any product,while striving through the“MET”indexes to reduce environmental impact throughout the entire

243、product lifecycle from material procurement and use,through final disposal.“MET,”meanwhile,refers to“Materials”(effective use of resources);“Energy”(efficient use of energy);and Toxicity(reduce the use of substances potentially harmful to the environ-ment).This concept is the foundation in determini

244、ng design and evaluation benchmarks,thus paving the way to Eco-Product creation.Under the Groups 4th Environmental Plan,the LCA(Life Cycle Assessment)method is applied to all products,with the goals managed under each aspect of MET in the development of Eco-Products.This stance also encompasses comp

245、lying with the recovery and recycling regulations for waste electric and electronic products and other requirements,as Mitsubishi Electric rises to role of being increasingly accountable as a producer.MET Indexes for Each Product in the 4th Environmental PlanBy the deadline date of December 31,2005,

246、Mitsubishi Electric will halt the use the six substances regulated under RoHS Direc-tive lead,mercury,cadmium,chromium hexachloride,PBB and PBDE to the product.Likewise,the deadline for banning the use of purchased materials and components from suppliers containing these substances has been set for

247、July 1,2005 an approach that has been steadily adopted from European-bound products.Setting Use Deadlines for RoHS-Regulated SubstancesThe Mitsubishi Electric Group has actively advanced the concept of“DFE”since 1991.The corporate environmental tech-nology committee consisted of DFE experts of each

248、factory draw up internal rules to realize DFE principles,while establishing the DFE Guideline*1,LCA evaluation and other design standards,while sharing actual designs and methods.Individual product designs are advanced in accordance with these Guideline.The effectiveness of this approach is quantita

249、-tively evaluated and verified using the 3R product assessment*2(comprising 14 large and 51 intermediate evaluation indicators),along with LCA,Factor X(see page 23)and other schemes.In-House Standardization of Design for Environment:DFE MethodsSimply stated,to be eco-friendly,designs must be customi

250、zed to the traits of specific products.For example,with IT equipment,which are characterized by short product lives,reducing both the impact of chemical substances contained in procured materials,and environmental impact at the time of manufacture and assem-bly,is key.For home appliances,which have

251、extended lifecycles,the key demands are energy conservation during use and easyrecycling of the waste products.The recycling plant owned by Mitsubishi Electric(see page 21)plays an important role in addressing these challenges.The know-how,themes and other information acquired from the plants oper-a

252、tions provide valuable feedback through close exchange with the design division,and is put to work in design for environ-ment.The most prominent feature of this approach is dismantling and recy-cling tests for a prototype model under development brought into the recycling plant.The estimated recycle

253、 ratios,total cost and other expertise gained from the recycle plant are reflected in the sub-sequent designs.Breakpoint design,barrier-free design and other original tech-nologies are the fruits of feedback from these recycling frontlines.Recycling Plant to Create New TechnologyUnder the 4th Enviro

254、nmental Plan,one of our goals is to raise the“Eco-Product”share of the groups total production value to over 70%by the end of fiscal 2005.In this regard,the shareof Eco-Products for fiscal 2003 was 49%of the 875.9 billion yen production value of the 81 product groups targeted for application.One app

255、roach is the increasing development of highly ad-vanced eco-friendly products referred to as“Hyper Eco-Prod-ucts”at Mitsubishi Electric.Our Goal is 70%Eco-ProductsThe Mitsubishi Electric Group drafted its Green Procurement Standards Guide in September 2000.This guide was used to con-duct surveys of

256、the environmental approaches used at suppliers,the chemical substances contained in procured product materials and other areas,striving to stay well abreast of the situation.In response to the subsequent RoHS(Restrictions on the use of Hazardous Substances)Directive,expanded corporate account-abilit

257、y and other changes in conditions in Japan and abroad,these standards were revised in August 2003.In this revised version,chemical substances were divided into four categories by“content and attachment bans”and“management target”levels.Standards were set for the handling and action plans applied to

258、each sub-stance,moving toward“Green Procurement”in production materi-als purchases that are further advanced.Based on these revised standards,a survey was completed in fiscal 2003 of the chemical substance contained in some 7,000 general-purpose electric/electronic components.Green Procurement Stand

269、ctrical home appliances,there is a sense of crisis.The true challenge is imagination envisioning what lies 10 years down the road.The Mitsubishi Electric Higashihama Recycle Center is the first recycling plant ever opened in the consumer electronics industry.The information here is naturally channel

270、ed to our product design division,and shared with other companies in the industry to raise the level and quality of environmental response.On this page we hear from Yasuhito Iseki of Hyper Cycle Systems,the company operating this state-of-the-art facility,about the work performed here.Progress in Re

271、cycle Design(Higashihama Recycle Center)Sorting and Scrapping Each Separate Material is Not Easy During the summer work peak,we will process up to 1,000 washing machines and 1,700 air-conditioners daily.Because most of the waste electrical home appliances brought to the Center were manufactured abou

272、t 10 years ago,the most challenging and costly work is to manually dismantling them and sort out each separate material.Dismantling,by its nature,is close to demolition.Though there is an urgent need for design for recycling,we can not afford to sit around and wait for such breakthroughs.Instead,we

273、are responding by promoting mechanical processing and other advances.This is particularly true of plastic materials,which rely heavily on mannual sorting by hand.Our goal is to mobilize the scale and technical skills of the center to promote greater mechanization of this process,and evolve it into a

274、“closed-circulation”recycling mode in which the plastic materials we sort out are re-used in new products.For this,we will need to perfect innovative new sorting methods as well as make progress in other areas.The plastics resourcerecovery technology developed in recent years is an example of succes

275、son that front.We break up the crushed plastic fragments containing metal shards and vinyl chloride-coated copper wire into even smaller pieces,re-move the metal and vinyl chloride through gravity and electrostatic separation,and recover high-purity plastic.Through these and other such efforts,we ha

276、ve succeeded in reducing the volume of plastic landfill dust to less than one-fifth the level when the Center first commenced operations.Technology to Make Eco-Friendliness Profitable,Not CostlyI am always making pleas to the design teams of the different plants.Inrecycling products manufactured ove

277、r the past 10 years,the trend has been to leave the work up to the recyclers,and hope that they can somehowresolve the problems.For products designed from now here on,however,I tell them to devote greater attention to recycling needs when they first draw up their designs!Moreover,this should not be

278、a halfhearted approach,finally yielding to pressure to preserve environment.On the contrary,I want thedesigners to work from a genuine sense of crisis.In our daily work at theCenter,we have come to understand that there will soon be nowhere todiscard waste products,and nowhere to safely incinerate w

279、aste.Without firm,dependable controls,such action will immediately contaminate the environ-ment.Before lecturing about the“global environment”and other lofty concepts,therefore,we need to devote serious thought to what we can do about the work operations in our own front yard.Obviously,recycling req

280、uires cost.But rather than always worrying about how costly protecting the environment is,we need to figure out how to make recycling profitable.At the very least,advances in closed-circulation recycling will help cut costs in this area.Just three years ago,for example,the idea of reusing plastic re

281、covered from waste electrical home appliances in new products was dismissed as great folly.But today,we are doing just that.In this way,we need to take advantage of the potential that has always existed,joining forces to cultivate technology capable of extracting value from spent products and other

285、ls are removed from waste home appliances and other products arriving at the end of their service lives,and revived through effective use as recycled resources.To support this social mission,Mitsubishi Electric emerged as an industry pioneer with the establishment of the Higashihama Recycle Center(H

306、t in product value and reduction in environmental impact,the initial goal is to reach“Factor 4,”while steadily contributing to the creation of a sustainable society.Factor XEnvironmental Substainability Report 2004“Factor X”is an index used to evaluate reductions in environ-mental impact and technic

307、al advances made in products andservices.The approach was first proposed in the early 1990s bya German researcher,who envisioned it as a target to be realized over the following 30 to 50 years.The“X”value,which servesas the goal,uses different levels to express specific areas ofprogress,which are:co

308、nventional improvements(Factors 1 to 3),major design changes(Factors 3 to 10),and de-materialization levels(Factor 20 and up).In a nutshell,the higher the factor,the greater the sustainability of the product measured.Mitsubishi Electric first adopted Factor X in December 2001,and has continued to pu

309、blicize the results.Measuring Advances in Eco-Efficiency with Unique ComputationsComputing Factors for Both Performance Improvement and Environmental ImpactAt the Mitsubishi Electric Group,we calculate Factor X using our own method,with the“MET”formula,for trial computations of the social contributi

310、on offered by individual products.Generally“eco-efficiency”is calculated through the formula of“productperformance environmental impact.”With the conventional factor calculation approach,the stress on the degree of contribution by environmental impact factors treated product performance im-provement

311、 as a constant(denominator-1).From this fiscal year,however,improvements in product performance have also been reflected in the calculation formula,evaluating both product im-provement and environmental impact reduction.Used in calculating environmental impact,meanwhile,are the three indexes of“non-

312、recycled resource consumption,”“energy consumption”and“Content of chemical Substances potentially risk to the environment.”Benchmark products(as a general rule,products manufactured in house by Mitsubishi Electric in 1990)are treated as“1”for each index.The three indexes are then ap-plied to the pro

313、ducts under evaluation,the results being integrated to calculate the current environmental impact compared to 1990(1.0).Factor X is an evaluation index used to compare in-house prod-ucts.Because factor definitions,benchmark products,calculation formulas and other details differ from company to compa

314、ny,Factor X cannot be used as a product selection guide.It is,however,an effective key in creating Eco-Products.This led the“Eco-Efficiency Investigation Panel”(which maintains its secre-tariat in the Japan Environmental Management Association for Industry)to prepare the“Guide to Product Eco-Efficie
