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 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)
is carbon negative!
- Sequesters up to 50% of the initial carbon (C) input and returns it to the soil.
- The initial loss of C is used for energy production to offset fuel use.
- Can use agricultural residues but DOES NOT require new crops to be grown to fuel the process
