Abstract
The replacement of natural fiber with biochars to prepare biocomposites has attracted widespread attention recently. Biochar has unique properties, including the porous structure, large specific surface area, high thermal stability, good conductivity, renewable and abundant feedstock source, and environmental friendliness, which provide excellent properties, environmental benefits, and low production costs for biochar-based composites. Biocomposites from organic solid waste-derived biochars show good prospects worldwide in terms of positive social, environmental, and economic impacts. This paper reviews current biochars, elucidates the effects of biochars on the characteristics and performance of biochar composites, and points out the challenges and future development prospects of biochar composites.
Highlights
The acceleration of urbanization, industrialization, and population growth rapidly increases the production of organic solid wastes [1], which can be divided into agricultural wastes, forestry wastes, industrial processing wastes, and municipal wastes in terms of sources [2]
The aim of this paper is to provide details of the main factors of the properties of biochar composites based on biochar properties, while the ultimate goal is to identify the challenges encountered in biochar composites and evaluate the potential of the conversion from organic solid wastes to high-value products
This paper gives an overview of biocomposites made from biochars that are produced from organic solid wastes
Summary
The acceleration of urbanization, industrialization, and population growth rapidly increases the production of organic solid wastes [1], which can be divided into agricultural wastes, forestry wastes, industrial processing wastes, and municipal wastes in terms of sources [2]. Biocomposites are prepared using dried organic solid wastes as fillers and polymeric materials as matrixes by melting and compounding, and this indicates that pollution generation can be reduced or eliminated in the productive process of biocomposites [9,10,11]. The aim of this paper is to provide details of the main factors of the properties of biochar composites based on biochar properties, while the ultimate goal is to identify the challenges encountered in biochar composites and evaluate the potential of the conversion from organic solid wastes to high-value products
