| Abstract: | Increasing the application fields for biochar presents an opportunity to replace fossil-fuel derived products with carbon-neutral biomass. However, to do so successfully the biomass, process requirements, product-use and end-of-life must be appropriately researched and evaluated. In this review biochar applications beyond soil were conceptually mapped and the addition of biochar to produce composites was identified as a niche theme with biodegradable plastics in particular showing promising potential for further development in the context of a circular economy. A meta-analysis of 20 bio-composite characterisation studies found that biochar up to 20 wt % produced from various feed-stocks and under differing pyrolysis conditions can lead to viable, or even biocomposites with improved properties for a number of bio-polymers. A set of recommendations for future biochar-PLA composite characterisations was suggested based on a qualitative evaluation of the publications under review. Due to the foundational nature of the research further biochar characterisation, biodegradation studies and sequential applications for biocomposites were identified as key future topics to evaluate if biochar-biocomposites are a promising application in a low-carbon circular economy. |
