Food loss due to wastage is a severe issue for the entire world. Wastage
accounts for up to one-third of lost food output globally. Although there are various
ways to turn food waste into useful functional materials, landfilling is still a frequent
practice. This results in greenhouse gas emissions, which increase the already
significant greenhouse gas emissions linked to the agriculture sector. In this review, we
start by identifying multiple biomass sources and synthesis methods for biochar made
from biomass. This contains methods for the characterization of phase change polymer
nanocomposite materials impregnated with biochar. In order to compare the thermal
properties of phase change materials and gain an understanding of the various
biowastes, a comprehensive methodology was used.
Keywords: Biomass, Biochar, Composite Phase Change Materials, Energy Storage, Sustainability.
