ABSTRACT:
Fabric material having a backing, such as carpet, is used as a biomass fuel component. The fabric material is shredded and substantially separated into constituent backing and fabric components. The backing component is stored in a first storage unit. The fabric component may be mixed with another biomass fuel component before introduction into a gasifier. The gasifier produces synthetic gas, which is subsequently used to produce steam. The hot ash generated as a by-product of gasification is stored in a second storage unit. Each waste product may be confined to a distinct waste path such that the waste products remain isolated from each other, at least until the ash cools down to approximately the melting point of the backing component.
