Abstract African balsam ( Daniella oliveri ) leaves and cow dung are waste materials that commonly accessible in Africa can be used to produce biochar by simultaneous thermochemical processing. In this study, was produced a retort‐heated, non‐electrically powered, top‐lit updraft reactor using the biomass fuel‐powered conversion of dried at an average temperature 320 °C. The characterized Fourier transform infrared spectroscopy (FTIR), energy dispersive (EDS), scanning electron microscopy (SEM), differential thermal analysis/thermogravimetric analysis (DTA/TGA), Brunauer–Emmett–Teller (BET) analyses. After carbonization for 100 min, obtained from processed mixed leaves/cow with yield 70%. showed presence alkene, hydroxyl, alkyne, alkane, sulfur‐containing functional groups. Scanning micrographs biochar's surface made up fibrillated particles very few pores. observed have area 328.199 m 2 /g higher pore volume lower size than alone. Energy is mostly carbon (67%), introduction into feedstock increased its carbon, silicon, potassium, bromine content. Differential analyses revealed thermally stable. findings study helpful attempts manage solid wastes (African dung), reduce environmental pollution, whose properties adequate it as soil additive. © 2022 Society Chemical Industry John Wiley & Sons, Ltd.

Prospects and problems in the development of biochar-filled plastic composites: a review

Functional Composites and Structures, Journal Year: 2023, Volume and Issue: 5(1), P. 012002 - 012002

Published: Jan. 9, 2023

Abstract This study is a review of published literature that discusses the utilization biochar (BC) and plastics as filler matrix, respectively, in composite material. These composites, referred to Biochar-filled plastic composites (BFPCs), play significant role production environmentally friendly materials. paper provides an overview BFPCs, their properties (mechanical, rheological, morphological, electrical, thermal properties), fabrication techniques, prospects challenges associated with development. Even though there have been previous studies on none these discussed drawbacks potential development BFPCs. BCs’ small weight makes them more appealing option than traditional mineral fillers when it comes reducing vehicle weight. Due superior mechanical qualities, well low carbon footprint, BC-filled (BFPCs) It was observed either melt extrusion or injection molding are usually used fabricate BFPC. BFPCs influenced by several factors such type concentration plastic, method fabrication, BC content, mixing uniformity mixture, wetting, particle dispersion. Challenges were also discussed, issue agglomeration poor interfacial bonding at high concentrations composite. Composites made from recycled polymers biodegradable can be developed improve composites’ overall sustainability.

Sustainable manufacture and application of biochar to improve soil properties and remediate soil contaminated with organic impurities: a systematic review

Frontiers in Environmental Science, Journal Year: 2023, Volume and Issue: 11

Published: Nov. 20, 2023

Biochar production and application have become increasingly popular in the past 15 years. Biochar, derived from diverse biomass types, offers a rich carbon source created through thermal combustion. primarily depends on pyrolysis conditions feedstock type. This review focuses multifaceted aspects of biochar, encompassing hydrothermal carbonization, gasification, temperatures biochar its role bioeconomy soil remediation. has yielded valuable insights, notably decreasing nutrient leaching, curbing greenhouse gas (GHG) emissions, reducing bioavailability environmental pollutants, sequestering (C) soils, enhancing agricultural productivity. Consequently, it emerged as commodity for bioeconomy, which involves harnessing bioresources bioengineering to create economically products. As marketable output, finds energy, biochar-based product manufacturing, sector. Thus, not only enhances quality but also unlocks additional revenue streams. underscores critical selection optimizing production. Furthermore, highlights sustainable effective tool improving various types remediating contamination caused by organic impurities, including persistent compounds antibiotics.
