Biocarbon from peanut hulls and their green composites with biobased poly(trimethylene terephthalate) (PTT)

Abstract There are millions of tons of post-food processing residues discarded annually. Currently, these waste materials are discarded to landfill, used as animal feed or incinerated. This suggests that there are potential uses for these materials in value-added applications. This work focuses on t...
