Environmental impact of biomass based polygeneration - A case study through life cycle assessment.

Multi-generation or polygeneration is considered to be a potential sustainable energy solution. To assess environmental sustainability of multi-generation, life cycle assessment (LCA) is a useful tool. In this paper, environmental impact of polygeneration using an agro waste (rice straw) is assessed by LCA.

Environmental impact of an agro-waste based polygeneration without and with CO2 storage: Life cycle assessment approach.

Life cycle assessment (LCA) is the most scientific tool to measure environmental sustainability. Poly-generation is a better option than single-utility generation due to its higher resource utilization efficiency and more flexibility. Also biomass based polygeneration with CO2 capture and storage may be useful being 'net negative' greenhouse gas emission option.

Integration of poly-3-(hydroxybutyrate-co-hydroxyvalerate) production by Haloferax mediterranei through utilization of stillage from rice-based ethanol manufacture in India and its techno-economic analysis.

Haloferax mediterranei has potential for economical industrial-scale production of polyhydroxyalkanoate (PHA) as it can utilize cheap carbon sources, has capacity for nonsterile cultivation and allows simple product recovery. Molasses-based Indian distilleries are converting themselves to cereal-based distilleries. Waste stillage (14 l) of rice-based ethanol industry was used for the production of PHA by H.

Techno-economic evaluation of a polygeneration using agricultural residue--a case study for an Indian district.

Presently, most of world electricity and other energy services are catered by fossil fuel resources. This is unsustainable in the long run both with respect to energy security and climate change problems. Fuel switching, specifically using biomass may partially address this problem.
