Preparation, characterisation and applications of bone char, a food waste-derived sustainable material: A review

Journal of Environmental Management, Год журнала: 2023, Номер 339, С. 117896 - 117896

The production of increasing quantities by-products is a key challenge for modern society; their valorisation - turning them into valuable compounds with technological applications the way forward, in line circular economy principles. In this review, conversion bones (by-products agro-food industry) bone char described. Bone obtained process pyrolysis, which converts organic carbon an inorganic graphitic one. Differently from standard biochar plant origin, however, also contains calcium phosphates, main component (often hydroxyapatite). combination phosphate and makes unique material, different possible uses. Here chars' environmental remediation, sustainable agriculture, catalysis electrochemistry are discussed; several aspects considered, including used to prepare char, preparation conditions, how these affect properties materials (i.e. porosity, surface area) its functional properties. advantages limitations chars comparison traditional discussed, highlighting directions research should take performances improve. Moreover, analysis on sustainability use included.

Abstract The development of sustainable and functional biocomposites remains a robust research industrial claim. Herein, the efficiency using eco-friendly biochar as reinforcement in Additive Manufacturing (AM) was investigated. Two AM technologies were applied, i.e., vat photopolymerization (VPP) material extrusion (MEX). A standard-grade resin VPP also biodegradable Polylactic Acid (PLA) MEX process selected polymeric matrices. Biochar prepared study from olive trees. Composites developed for both 3D printing processes at different loadings. Samples 3D-printed mechanically tested after international test standards. Thermogravimetric Analysis Raman revealed thermal structural characteristics composites. Morphological fractographic features derived, among others, with Scanning Electron Microscopy (SEM) Atomic Force (AFM). proven to be sufficient agent, especially filament process, reaching more than 20% improvement 4 wt.% loading tensile strength compared pure PLA control samples. In results not satisfactory, still, 5% achieved flexural 0.5 loading. findings prove strong potential biochar-based composites applications, too. Graphical
