A critical study of sustainable biocomposites developed from rheologically distinct poly(butylene adipate‐co‐terephthalate) (PBAT) reinforced with biocarbon from coconut (Cocos nucifera) for rigid applications

The Canadian Journal of Chemical Engineering, EarlyView.
This work highlights the development of a sustainable composite with improved dimensional and thermal stability as well as mechanical performance, for rigid application. To promote sustainability and a circular economy, we have reduced PBAT percentage content by half and incorporated waste coconut shell up to 50 wt.%.
