Gaseous products from biomass and waste co-pyrolysis - DOE

Previous research has demonstrated that including waste polymers into thermally converted biomass has a considerable impact on the quantities of solid, liquid, and gaseous products that can be extracted from the biomass. Therefore, it was decided to investigate how the addition of waste polymers could affect the composition and overall quality characteristics of the gaseous products obtained during the co-pyrolysis of three different biomass-derived materials with the addition of two different multicomponent blends of waste polymers. These waste polymers included polyethylene terephthalate (PET) from PET bottles recovered from municipal solid waste (MSW), polypropylene (PP) from scrap bumpers, and acrylonitrile (ABS).
