Waste management is becoming a crucial issue in modern society owing to rapid urbanization and the increasing generation of municipal solid waste (MSW). This paper evaluates the carbon footprint of the waste management sector to identify direct and indirect carbon emissions, waste recycling carbon emission using a hybrid life cycle assessment and input-output analysis. China and Japan was selected as case study areas to highlight the effects of different industries on waste management. The results show that the life cycle carbon footprints for waste treatment are 59.01 million tons in China and 7.01 million tons in Japan. The gap between these footprints is caused by the different waste management systems and treatment processes used in the two countries. For indirect carbon footprints, China’s material carbon footprint and depreciation carbon footprint are much higher than those of Japan, whereas the purchased electricity and heat carbon footprint in China is half that of Japan. China and Japan have similar direct energy consumption carbon footprints. However, CO2 emissions from MSW treatment processes in China (46.46 million tons) is significantly higher than that in Japan (2.72 million tons). The corresponding effects of waste recycling on CO2 emission reductions are considerable, up to 181.37 million tons for China and 96.76 million tons for Japan. Besides, measures were further proposed for optimizing waste management systems in the two countries. In addition, it is argued that the advanced experience that developed countries have in waste management issues can provide scientific support for waste treatment in developing countries such as China.

Manufacturing process planning serves as a pivotal link between design and manufacturing. Process planning decisions play a critical role in determining the cost and environmental impacts associated with manufacturing. Past efforts to address environmental issues during process planning are briefly reviewed and potential approaches that can achieve reduced environmental impacts are then discussed. A proposed method is presented for environmentally conscious process planning. The method begins with an existing process plan, and then identifies impactful process steps, and associated design features, in terms of manufacturing cost and environmental impact. Alternative processes that can achieve these features are then considered to generate alternative process plans. These alternatives are then evaluated in terms of economic and environmental performance. The results of these evaluations are then used to generate a set of process plans that are non-dominated with respect to manufacturing cost and environmental impact objectives to produce a Pareto frontier. The proposed method is demonstrated using the manufacturing of a prosthetic hip shell as a case study.

将大鼠脑神经膜微移植到非洲爪蟾卵母细胞的质膜中,是一种利用标准电生理学方式研究其天然态通道和受体的体外方法。在本文中,我们发现注射了成年大鼠脑神经膜的卵母细胞会引发对河豚毒素敏感的膜去极化内向离子流,经除虫菊酯类杀虫剂氯菊酯和溴氰菊酯处理后,该电流呈浓度依赖性增加。根据我们最初的方案,随着时间的推移,卵母细胞的健康水平会降低,不同批次的不同蛙类卵母细胞间与神经膜的结合程度也不同,这限制了该试验在调控问题上的实用性。对分析程序、数据接受标准和分析方法的一系列更改可显著提高试验的精度,从而提高性能。这些变化促使这种体外方法成为一种毒理学相关分析方法,以研究拟除虫菊酯对取自幼年和成年大鼠脑中的神经膜片段的离子通道的毒性作用。
