Gasification systems that convert non-recyclable organic waste (bark, sawdust, clean construction/demolition debris, biosolids from sewage sludge) into a product called "syngas" that can be used to fuel heat and power. This novel process has low air emissions and particulate carryover, reducing emissions controls and permits costs. The design is also very simple and has few moving parts. The gasification system can process many challenging renewable waste feedstocks with moisture contents ranging from 6-60% and sizes up to 75 mm. These systems operate reliably on wood (bark/chips and sawdust), clean construction and demolition debris, and biosolids from sewage sludge. Other feedstocks include refuse-derived fuel, poultry litter, compost material, switchgrass, and agricultural residues.
