Dow and New Energy Blue partner on bio-based ethylene from corn stover

Green Car Congress

Dow’s agreement with New Energy Blue, staffed by experts with deep experience in bio-conversion ventures, is the first agreement in North America to generate plastic source materials from corn stover (stalks and leaves). This is also Dow’s first agreement in North America to utilize agriculture residues for plastic production.

KIST team develops technology for mass-production of lignin-bio-aviation fuels

Green Car Congress

A Korean research team has developed a technology that can be used to mass-produce aviation-grade fuels from wood wastes. Large volumes of lignin are generated as waste in the pulping processes that are used to produce paper. The results of the study were published in the latest issue of Energy Conversion and Management.

Panasonic develops highly efficient artificial photosynthesis system with gallium nitride semiconductor for conversion of CO2 to formic acid

Green Car Congress

This will make it possible to realize a simple and compact system for capturing and converting wasted carbon dioxide from incinerators and electric generation plants, according to Panasonic. The conversion efficiency of solar energy to chemical energy was 0.03-0.04%. Hiroshi Hashiba et al. 243904 doi: 10.1063/1.4729298.
