Improving poor soil with burned up biomass

Researchers at the RIKEN Center for Sustainable Resource Science in Japan have shown that torrefied biomass can improve the quality of poor soil found in arid regions. Published in Scientific Reports, the study showed that ...

A corny turn for biofuels from switchgrass

Many experts believe that advanced biofuels made from cellulosic biomass are the most promising alternative to petroleum-based liquid fuels for a renewable, clean, green, domestic source of transportation energy. Nature, ...

Gene discovery to increase biomass needed for green fuel

(PhysOrg.com) -- Manchester scientists have identified the genes that make plants grow fatter and plan to use their research to increase plant biomass in trees and other species - thus helping meet the need for renewable ...

New studies sully reputation of biomass as clean and green

Simpson Tacoma Kraft would seem like one of the greener power plants. It boils water by burning sawdust, bark and wood shavings from saw mills and pulp mills, funneling the resulting high-pressure steam into a turbine to ...

Unprecedented worldwide biodiversity study

Humans depend on high levels of ecosystem biodiversity, but due to climate change and changes in land use, biodiversity loss is now greater than at any time in human history. Five University of Alberta researchers, including ...
