Data were collected and analyzed for business facilities that introduced a domestic renewable energy heat utilization system. The welfare facilities in Shisui Town have introduced a solar-heat / ground-heat hybrid system, and the annual COP was 0.65. It has been found that the COP is improved by about 40% by applying the improvement proposal. In addition, analysis of data from large-scale heat supply districts across the country showed that the average system COP and CO2 emissions were most efficient in the power-based business, and there was a correlation between COP and CO2 emissions.

In this paper, we measured a solar-thermal and ground-thermal hybrid energy system in Honjo city. In this system, hot water warmed by solar-thermal is used to back up the hot water supply. It is also used as a heat source for an adsorption refrigerator. From the ground-thermal heat pump, hot water and cool water are supplied to restaurants. Energy utilization factor in this energy supply system is as low as 0.5 in the summertime. In July 2018, there was a problem that air conditioning did not work under the influence of intense heat. We investigated the cause and found that the capacity of the heat pump has about 30 kW of power shortage. In order to improve the energy supply system, we investigated whether an adsorption type refrigerator is necessary and calculated the number of solar heat collectors required. Results showed that the adsorption refrigerator only lowered the ground temperature by about 1 to 2°C and the optimum number of collectors is seven.

We investigated a combined system of the garbage disposal facility and sewage treatment facility in Japan. We evaluated the environmental and economic efficiency for the facilities with waste disposal scale of 300t / D and 50t / D in six constructed scenarios.

近年，循環型社会の構築に向けた取り組みの一環として食品リサイクルの促進が注目を浴びている．しかし各リサイクル技術に対する環境負荷や経済性の評価を統括的に行った研究や評価ソフトが現状では存在していない． 本研究では乾燥飼料化，堆肥化，メタン発酵，エタノール化の4技術を利用した事例を収集し，環境負荷と経済性評価の把握と比較を行える評価ソフトを開発した．これにより各リサイクル技術の定量評価を可能にし，周辺インフラや地域特性との連携の重要性を明らかにした． さらに，埼玉県本庄市をモデルとしたケーススタディを行った．具体的に，清掃工場や下水処理施設などの既存インフラの調査や，未利用の食品系廃棄物の排出量を推計し，こうした地域特性を考慮した最適な有効利用システムの提案と評価をした．その結果本庄市において，現実的にはメタン発酵施設と既存インフラを併設したケースが最も効果があることがわかった．

自動車リサイクル法見直しに関する会議（産業構造審議会 環境部会廃棄物・リサイクル小委員会自動車リサイクルＷＧ中央環境審議会 廃棄物・リサイクル部会自動車リサイクル専門委員会合同会議）のなかでリサイクルの高度化について議論がなされ，解体性の向上やリサイクル性を考慮した素材の使用等，環境負荷の低減およびリサイクル率の質の向上にむけ環境配慮設計(DfE:Design for Environment)が注目されている．こうしたなか，DfEの導入促進に向けて，それを客観的に評価していくことが求められるが，その評価手法については十分な検討がなされていない現状がある．そこで，筆者らは，自動車の実解体試験を行いELP法(Environmental Load Point2))を通してDfEを時系列で比較することでDfEの定量化を試みた．

焼酎かすをそのまま養豚飼料として利用する事業が鹿児島県の焼酎醸造会社と養豚事業者の間で行われ始めて8年が経つ。&lt;br&gt;本稿ではこれだけ長期に渡って大規模に、また大きなトラブルも無く実施して来れた理由を考えるとともに、我々がデータ解析を行って発見した当事者たちも気づいていなかった改善を要する点について紹介すると同時に、他の水分含有量の多い素材への応用についても提案する。

レアメタル等の資源確保が求められるなか，使用済み小型家電のリサイクル法が施行され，その回収から処理までを含めた資源回収システムの構築が検討されているが，その設計方法に関しては十分な検討がされているとはいえない. 本報では,埼玉県で実施した使用済み小型家電等の破砕選別実験を通じて,破砕処理施設への投入物と回収物の関係性を導き出し，筆者らがこれまでに各種小型家電を手解体することで構築してきた「DfE定量評価データベース」に蓄積された製品の素材構成から回収物の重量を推計する方法を検討した．さらに埼玉県内の自治体の使用済み小型家電のリサイクル状況・問題点を把握し，手解体工程や最新設備の導入効果を経済性・環境性の面から評価した．

食品系廃棄物は再生利用やエネルギー利用の観点から着目されているが，事業継続を行うことが非常に難しいと言われている．なかでも，処理量の安定確保が事業継続において重要だとされているが，現状では食品系廃棄物の量を把握するための先行研究がほとんどされておらず，十分な取り組みが進んでいるとは言い難い状況にある． そこで，本研究では循環型社会の構築に寄与することを目的に，業種ごとにおける食品系廃棄物の賦存量，未利用資源量の排出原単位を各種報告書を活用することで構築した．さらに，排出原単位と地理情報システム(GIS)を連携することによって食品系廃棄物の排出実態の可視化を行った．そして，その整合性を確認するために，収集・運搬業者の実際の回収店舗の空間分布状況が推計賦存量の高いエリアにある程度の一致性が見受けられ，回収量の実績値と推計値に関しても誤差が約8％となっており，非常に精度が高いことが判明した．

循環型社会の構築が求められている中で，各自治体の廃棄物の処理体系に関する調査を進め，特に，山元還元として注目されている溶融飛灰の取り扱いについて深く調査してきた．さらに，東日本大震災の影響により，放射性廃棄物等の問題から溶融炉は転換期を迎えている．本稿では，震災後初となる溶融施設のデータ収集であり，これまでの集計結果との比較検討を行った．結果として，震災が原因で停止した溶融炉を地方別で見ると，東北・関東地方での停止が目立つ結果となり，津波・地震による耐火物の落下等の外的損壊，停電あるいは夏季計画停電を配慮したことが停止の理由として挙げられた．また，全国的に多くはないが，施設ごとに受入廃棄物に対して放射能の基準値を設けている溶融施設もある．そこで，全国の放射線対策状況を調査したところ，東北・関東地方では検討，実施している施設があるものの全国的には未だに検討していない施設が多いことが分かった．

For the purpose of developing a low cost bio-oil production process, we have investigated rapid pyrolysis of woody biomass by using an entrained flow reactor as the key device. The entrained flow reactor was selected because of the fine controllability of reaction temperature and residence time, which were the main factors affecting liquid products yield. In the bench-scale testing facility with entrained flow reactor, wood particles were rapidly pyrolized and the products were collected to analyze. The yield of bio-oil was higher than 50wt% compared with the fed biomass in dry weight. The obtained bio-oil formed two layers, which were hydrophilic layer containing condensed water and hydrophobic layer settled on the bottom. The moisture of hydrophilic layer should be removed and the products are expected to use as an alternative to heavy fuel oil.

Combustion tests were conducted in an actual incineration plant in order to evaluate the bio-oil as alternative kerosene. Large differences in combustion characteristics, such as exhaust gas compositions and temperature conditions, were not observed in these tests, so that the bio-oil is considered to be used as a kerosene alternative.

環境負荷の低減は環境配慮設計により実現されるが、環境に配慮した製品とは3R（Reduce、Reuse、Recycle）に配慮することであり、資源の有効活用や有害物質の適正処理等がその方策として考えられる。Reuse、Recycleに着目すると、工業製品は分離／解体と破砕／選別により環境負荷低減され、そのためには易解体性の向上が求められる。そこで、解体性を定量的に評価する手法として分解性評価指数を、環境負荷を定量的に評価する手法として環境効用ポテンシャル評価手法を開発し、製品の解体性の向上と環境負荷低減の最適化を図ることを目的としている。本報では、ハイブリッド自動車用バッテリー（以下、HEVバッテリーという）を例とした評価事例を示し、その活用方法について提案する。

環境問題の深刻化に伴い，持続可能な社会の構築が急がれている．都市の持続可能性という観点では，環境分野のみならず，地域の社会・経済の発展という側面からのアプローチが求められる．これを両立し，実行するための方策のひとつとして，われわれは地域環境通貨を提唱してきた． 本稿では，北九州市で行われている北九州市民環境パスポート事業（以下，環境パスポート）での実証実験をもとに，ポイントの交換履歴を追跡するシステムと市民活動の情報収集および開示を推進する手段として，カンパスサイトの開発について取り上げる．また，市民の環境に対する取り組みの集合体として，都市全体の環境負荷を算出し，環境負荷の変動の要因や削減方法について考察した．

平成17年1月1日より自動車リサイクル法が本格施行され，それに伴い自動車を取り巻く環境に種々の社会変化が起こっている．そこで，自動車のリサイクルの現状を把握するため，ASRの処理における実績評価を行った．各自動車メーカーの再資源化の実績を評価し，自動車リサイクル法施行による効果の評価と再資源化率の向上策について検討することを目的とする．ASR再資源化率と収支の関係では，THチームとARTチームの特徴を確認した．また，2004年から2005年にかけての両チームの改善された点を確認した．回収物を投入資源量で按分した結果，各処理方法で特徴的な傾向があることを確認し，ASR専門で処理を行っている素材分別施設の回収効果が大きいことを確認した．また，THとARTの指定取引場所別に評価したところ，THが優れている処理方法，ARTが優れている処理方法があるが，総合的には両チームに大差はないことを確認した．

近年の都市の持続可能性という観点から，環境と地域の社会・経済の発展の両面でアプローチが求められている．これを実行するための方策のひとつとして，われわれは地域環境通貨を提唱してきた．本研究では，北九州市で行われた地域環境通貨を具現化する北九州市民環境パスポート事業の実証試験の一環として実施した市民・事業者の環境活動をアンケート調査により分析し，また，地域環境通貨のメニューの一部であるカーシェアリングの有効性を示すことで，企業，行政，市民の連携による環境配慮の向上及び都市の意思決定ツールとしての環境評価指標の開発を目的とした．結果，カーシェアリングはわれわれが開発した統合化指標ELPで83.6%の削減効果があり，環境負荷の削減に有効なシステムであるとの知見を得た．また，環境パスポート事業実証実験では，実行容易度によるポイント決定が，参加者の希望と環境負荷削減の両面に即しているとの結論を得た．

資源循環型社会の構築が求められているため各種工業製品の設計・生産段階における3R（Reduce、Reuse、Recycle）配慮性が必須である。本研究では、特に、リユース・リサイクルに必要な解体性を評価可能な分解性評価指数を提案している。この指数を用いた解体性評価と実際のリサイクルプロセスとの関係を調べるため、リサイクルプラントを対象とし、製品のライフサイクルが短い遊技機、家電リサイクル法対象製品であるテレビ、冷蔵庫、エアコンを対象に解体性の実態調査を行う。

香川県豊島で起こった国内最大級の産業廃棄物不法投棄事件は現在，住民との間に調停が成立し，豊島廃棄物等処理事業が行われている．この豊島における廃棄物等不法投棄現場の処理事業は住民，行政，島外の支援者の「共創」の理念のもとで進められ，この理念からも事業の進捗状況を解りやすい情報として，関係者に示し共有することが重要である． 本研究では処分地の地形をGPS測量手法により調査し，それから求められる掘削体積量を知るとともに，各工程での処理相当量との整合性を検討し，事業の進捗状況を管理するツールとしての有用性を示す．あわせて，処分地の地形データの３Dモデルを活用し，処理対象物をすべて処理したあとの地形と現状との違いなどを簡便に表示するなどの情報公開手法について検討する．

豊島廃棄物等処理事業は「共創」の理念のもとで進められている．その中で豊島・直島の住民や関係者には，事業の監視の役割が求められている．一方，事業者である香川県では，適切な情報の公開や住民等からの意見の反映が必要とされる．こうした対応には，事業の進行に合わせた情報整理の方針と公開のルールが必要と考えられる。本報告では，特に毒性の強いダイオキシン類の管理に寄与する検討を行った．具体的には，平成16年秋の台風に伴う異常降雨により豊島処分地から管理基準を超えるダイオキシン類を含む雨水が処分地内の沈砂池への流入したことの汚染原因を，DXN同族体分布を用いたクラスター分析で検討，および処分地西海岸に打ち上げられるダイオキシン類を含む黒色物質に関しても同様の分析と顕微鏡観察やX線回折分析，蛍光X線分析を行い、これらが樹脂やゴムなどの工業製品の廃棄物の焼却残渣であることを特定した．

近年、循環型社会に対応した廃棄物処理体系の構築が必要とされている。一般廃棄物処理は，ごみの排出段階から収集輸送・処理・リサイクルまでの段階に分かれており，筆者らはこれまで各段階において評価手法を開発してきた．さらに，各段階の検討事項は相互に関連しているため，システム全体を考慮した評価が求められ，環境・経済的に優れたシステムの構築が必要となる．そこで，TLCA（Technology Life Cycle Assessment）とLCC(Life Cycle Costing)を考慮した包括的な評価方法CLCA(Comprehensive Life Cycle Assessment)の考え方を導入し，その中で最適なシステム（BAS：Best Available System）の提案手法について検討する．本研究では，そのBAS提案のためのツールとして，プラントメーカーや自治体から提供していただいたデータを基に，ユーザーの中心となる自治体が利用しやすい「一般廃棄物処理技術のBASソフトウェア」の開発を行った．

2005年1月1日より自動車リサイクル法が本格施行された。それに伴い、自動車メーカーなどは、シュレッダーダスト（ASR）、エアバッグ類、フロン類の引き取りを義務付けられており、引き取ったASR及びエアバッグ類については、再資源化すべき量に関する基準に従って再資源化する義務を負っている。そこで、ASR再資源化の実効状況を客観的に評価することを目的とし、各企業が公表するASR投入施設活用率を基に環境負荷評価手法であるELP（Environmental Load Point）を用いてLCA評価を行った。

飲料容器には、PETボトル、アルミ缶、スチール缶、紙パック、ビンなど様々な素材を用いた製品があり、また、ふたがある製品などその機能も多種多様である。このような製品を正当に比較評価するためには、環境負荷に加えて、製品の機能面や利便性等のプラスの側面を評価することが可能な定量的手法が必要であると考える。そこで、本研究では、消費者が求める本質的な要素を飲料容器の「効用」と定義し、その定量化手法に関する検討を行うこととする。なお、場面に応じて飲料容器の効用は異なると考え、「屋外」、「屋内」という2種類の効用を作成することとした。

近年、循環型社会構築に向けて重要な役割を担う廃棄物処理関連施設において、事故やトラブルの発生が頻繁に報告されている。そのため、廃棄物処理施設における安全・安心への関心が高まり、廃棄物の安全かつ適正な処理が求められている。本研究では廃棄物処理関連施設における事故やトラブルの未然防止、拡散防止、安全体制の構築などを体系的に実施し、施設設計や操業時の安全性および周辺住民への安心感醸成などを実現することを目指し、事故・トラブル事例/安全向上策データベースの構築とこれをベースとした安全設計解析手法の開発、施設運営等における操業管理システムの構築とバーチャルリアリティなどの新技術を駆使した効果的・効率的な施設運転者の教育に資する人材育成プログラムの開発、施設周辺住民等の「安心」を確保するためのわかりやすい情報共有・情報伝達の方法論の開発等に関して検討した。

近年、地球環境問題や安全・安心に対する関心が高まり、廃棄物の安全かつ適正な処理が求められている。しかし、一般廃棄物処理施設における事故多発が多方面から報告されており、既存の廃棄物処理システムは社会的な信頼を得るには至っていない。こうした背景から、廃棄物処理施設に内在するリスクを洗い出し、施設の設計段階で簡便に活用可能な安全設計解析手法の開発を行った。本手法は、利便性に配慮した事故・トラブル事例データベースを構築し、これと連携することによって被害額とその発生率からリスクを定量化する手法である。また、安全向上策と連携して評価を行うことで、経済性も考慮した安全設計の検討を行える手法を提案した。

近年、日本国内における廃棄物発生の増加とその質的変化によって、多くの自治体で処理方策の検討が進められている。とりわけ、焼却処理における溶融処理は、廃棄物の減量化による最終処分場の維持・管理および延命化に寄与するとともに、資源の循環的利用を促進するための有効な手段となる。溶融処理では、発生するスラグの再利用は多く検討がなされているが、同時に発生する溶融飛灰の取り扱いに関しては、そのほとんどが埋立処理されているのが現状である。溶融飛灰は高濃度に重金属を含有した廃棄物であると同時に有用資源でもあるため、適切な保管と輸送、再資源化が必要とされている。 そこで、本研究では既存の非鉄製錬の技術を応用した溶融飛灰の資源化処理および、溶融飛灰処理に伴う広域輸送の環境負荷評価を行うと伴に、経済性も含めた評価を行い既存の埋立処分と比較し実現可能性の検討を行う。

近年、様々な地球規模の環境問題が深刻化しており、わが国でも循環型経済社会への移行が望まれている。あらゆる場面で環境に配慮した生活が求められており、個人の環境活動への積極的な参加が必要であると考える。そこで、本研究では，自分達こそが消費者であり環境負荷低減の可能性を秘めているという意識を励起させることで、環境に配慮した行動を促進することを目的とし、工学的視点を導入した学童向けの実践的な環境学習プログラムの開発を行う。消費者の視点に立ち、より実効力のある行動を環境学習プログラムを通じて提案し、自ら考え行動していく姿勢を身につけることを目的とした。大学主催の小中学生向けの科学実験教室「ユニラブ」にて工学的視点を導入した５つの環境学習プログラムを実施した。そこから得られた知見をもとにより消費者教育向けに、「お菓子の包装」を題材とした環境学習プログラムの検討を行った。

In addition, we developed LSA software to do ELP (Environmental Load Point), our own LCA valuation method, calculation of the whole lifestyle easily and enabled that we grasped environmental load of the whole life quantitative and visual.

The writers suggested ELP (Environmental Load Point) as LCA (Life Cycle Assessment) valuation method to evaluate environmental load quantitatively. ELP is classified into &quot;Panel Method&quot; and we carried out questionnaire for estimating category weight with some questions about LCA for the purpose of getting an indicator for practical use of future LCA technique and development. Then, we take a surge of interest to environmental problems of these days, we try to research the category weight by doing the questionnaire above. The targets are students, domestic public, environment experts. We conpared with a questionnaire result of the past in that and examined how the consciousness change for environmental problems with times.

To construct the Sustainable Society, the importance of consideration to 3R (Reduce, Reuse, Recycle) in the design phase increases in various industrial products. Concerning Reuse and Recycle, the improvement of the disassembly property is important. Then we develop the quantity disassembly property assessment method Disassembly Property Index (DPI), one of the DfE (Design for Environment) supporting tool. In this paper, we pay attention to bicycles. Recently, bicycles are produced and wasted in large quantities, therefore, it is hoped to be sustainable. Then, we examine the consideration of 3R. about bicycles. And also, we develop Disassembly Supporting Software which support the disassembly process of used products by showing disassembly flow and 3D animation

In recent years, global environmental problems become aggravated, and the shift to the sustainable society is required. The quantitative environmental load assessment is necessary to achieve the sustainable society. Though various LCA (Life Cycle Assessment) method is developed for such a demand, it is pointed out that there are a lot of problems in existing LCA. To solve such problems, Eco-Efficiency Potential Assessment (E2-PA) is developed. E2-PA is based on the concept of &quot;Eco-Efficiency&quot; and the &quot;Potential Assessment&quot;. In this research, we pay attention to &quot;Utility&quot;, the numerator element of the E2-PA, of the products. Utility is the quantitative index means the essential factors of products in terms of consumers. We propose a method to quantify the Utility, which is the great merit of E2-PA. The targets in this paper are notebook computers. The case study of Utility assessment and calculation of Total Index (TI), which is the integration index of E2-PA. is shown.

In recent years global environmental problems become aggravated, and various energy-saving function and method have been introduced in vending machine. However, it is reported that useless energy is consumed because the amount of power consumption changes greatly by the installation environment in actual operation. Then, it aimed to achieve efficient conservation of energy by managing operational information on the vending machine, we did the monitoring investigation to the vending machine in the university premises. When the conservation of energy setting matched to the use state was given, the amount of power consumption of about 17.8% was reduced to 8 vending machines selling cans and PET bottles, and about 17.3% was reduced to 3 machines selling cartons. We also developed a tool which is called Best Available Allocation Supporting tool. By using this tool, we plan to propose people who operate vending machines to save vending machines energy consumption without dropping off sales.

This paper presents the study of a monitoring and assessment for energy supply system of public facility with Co-Generation System (CGS). Recently, CGS is expected as one of the measures for global warming. However, there are many cases that the actual operation conditions of the energy supply system, like CGS are uncertain to practice to the energy saving at the facility. Then, we focus to public facility with CGS, and investigate the energy supply system. A monitoring and assessment are done in a certain hospital CGS. Concretely, total energy available efficiency of CGS is calculated by monitoring the heat balance in CGS. And we showed the comparison result with measurement value by applying various CGS assessment method and standard.

Recently, the mobility which is more comfortable than a thing of an article for handicapped people to obtain social barrier-free as well as necessity of mobility machinery for elderly society is demanded. We are aimed for development of an electric wheelchair as next generation mobility machinery which is equipped with a fuel cell system as a new energy source and which realized power-saving and lightweight. We set the target value by questionary survey to wheelchair users and strength analysis on software, and the body adopted lightweight material.

Recently, development and the spread of small, lightweight, environmentally-friendly and high-efficiency single-seat fuel cell electric vehicle are expected. Then, in order to realize this concept, we designed and manufactured for ULFCV (Ultra Lightweight Fuel Cell Electric Concept Vehicle) applying the development technology of competition vehicle. In this paper, to realize more practicability, we considered the power system and the body of the ULFCV. Then we selected best available fuel cell and capacitor and battery. On the other hand, we improved mass production type ULFCV to use in a car sharing system. We tried to reflect users&#039; opinions to the body design. Next, we simulated the ULFCV strength by FEM analysis for the purpose of confirming its safety.

In this paper, we aim at the construction of the environmental-friendly use system of automobiles whose large environmental load is pointed out as significant problems. Our base concept is &quot;Up-grading&quot; product, which realizes long life and environmental-friendly using by the up-grading of main components and also improvement of users consciousness. First, we performed an Eco-drive examination to realize its effect. As a result, we can get some effects by Eco-drive without average speed changing. Therefore, we propose the supporting device to promote the practicing Eco-drive. It is the device which the users can learn about Eco-drive after their driving with animation and running data. We aim to bring up eco-users and to improve the consciousness of drivers.

This paper presents the study of a development and assessment for bio ethanol mixing fuel boiler. Recently, bio ethanol is expected as one of the measures for global warming. However, we try to use it only for an alternative gasoline source, and we do not nearly consider other ways of using it. Then, we focus to boiler whose fuel is heavy oil or kerosene, and develop bio ethanol mixing fuel and bio ethanol mixing boiler. The boiler has the same performance of combustibility, and reduces almost 19% CO_2 and 27% ELP (Environmental Load Point) in life cycle compared with the boiler whose fuel is heavy oil or kerosene.

The construction of the waste management system corresponding to the recycling society is needed. The construction of Best Available System is hoped for in all respects of the municipal waste from the exhaust stage to recycle or final disposal stage with its evaluation. We understood the current state of the municipal waste processing, and developed the evaluation system that facilitated making the improvement idea for the processing plan to the municipality. Concretely, we did the questionnaire survey concerning the collection and the processing form to some cities for making the data base of the supporting tool and grasping the realities of their waste management system. Then, we arranged, analyzed, and proposed the Best Available System to the waste management system.

In recent years, global environmental problems become aggravated, and the shift to the sustainable society is required. The quantitative environmental load assessment is necessary to achieve the sustainable society. Though various LCA (Life Cycle Assessment) method is developed for such a demand, it is pointed out that there are a lot of problems in existing LCA. To solve such problems, Eco-Efficiency Potential Assessment (E2-PA) is developed. E2-PA is based on the concept of &quot;Eco-Efficiency&quot; and the &quot;Potential Assessment&quot;. In this research, we pay attention to &quot;Utility&quot;, the numerator element of the E2-PA, of the products. Utility is the quantitative index means the essential factors of products in terms of consumers. We propose a method to quantify the Utility, which is the great merit of E2-PA. The targets in this paper are television, used car, and the notebook computer. Through the analysis of the television&#039;s Utility, it was shown to be able to evaluate the product with a different adjustment technology, like CRT, LC and Plasma. On used car, the change in Utility before and after the ELV (End-of-Life Vehicle) Recycling Law was shown. On notebook computer, we took in the consumer&#039;s intention by questionnaire in the assessment of the Utility. By this study the necessity of the product development according to the knowledge level of consumers was shown.

In recent years, global environmental problems have been aggravated. Especially the revolution of our lifestyle is requested. So, we have suggested the LSA (Life Style Assessment) as the environmental load assessment method in one&#039;s everyday life, and have evaluated the effect of environmental load reduction by improving the behavior of life style. In this report, we paid attention to the environmental load caused by heating apparatus and clothes in our life. In heating apparatus we compared the environmental load, the cost, and the utility. On clothes we evaluated the environmental load of 24 products. Moreover, to do such an assessment in individual&#039;s life style, we developed the LSA software. By using this software we enabled to understand the environmental load in the entire life quantitatively and showed the effectiveness of it.
