Microbial electrosynthesis (MES) uses microbes and electricity to convert CO2 high-grade chemicals alleviating greenhouse gas (GHG) emissions. Little is known on the environmental loads associated with scale-up of technology. Initially, MES impacts synthesizing acetic, formic, or propionic acids, methanol, ethanol were assessed using GaBi LCA software, produced 60% from fossil fuels. The result...

This paper aims to analyze product life cycle, introduce green design concept and integrate it into so as establish feasibility path combining with China’s national condition. Through case analysis, five principles of co-creation, material reduction, packaging, replacement from identical were summarized according the attributes figment, product, commodity, article waste. The whole process was a...

For proper management of total product life cycle, it is fundamentally important to systematize design and engineering information about product systems. For example, maintenance operation could be more efficiently performed, if appropriate parts design information is available at the maintenance site. Such information shall be available as an information infrastructure for various kinds of eng...

Separation of concerns is accepted as introducing numerous benefits into software development and maintenance. In this position paper, we argue for a method that introduces separation of concerns into product line software engineering. The method covers the complete product line life cycle and integrates the different concerns expressed at the different product line life cycle stages.
