Biomass Pyrolysis

Biomass Pyrolysis is the thermo-chemical decomposition of organic materials by heating in the absence of oxygen. Controlled pyrolysis has been approved by the UN as a Clean Development Mechanism (CDM) for avoidance of methane production from biomass decay.

Gasification and burning of fossil fuels
is at best, carbon neutral.

burning of biomass

Burning of biomass at best sequesters only 3% of the initial carbon.

Dedicating land to biofuels increases carbon emissions.  In fact, ccorn-based ethanol can double greenhouse gas emissions over 30 years. (Searchinger et al. 2008, Science)  

Biomass Pyrolysis
is carbon negative!
