Research on using biochar for environmental applications has witnessed unprecedented advances in the past decade. Biochar is universally considered one of the best alternatives to store carbon to fight global warming. Thus, the sequential use of biochar in environmental remediation compatible with carbon sequestration is receiving growing attention. One of the reasons for such huge interest is the possibility to engineer biochar with targeted properties (e.g., surface area and chemistry) relevant to existing environmental issues. These properties can be achieved by selecting appropriate raw materials, processing conditions, carbonization technology, and the possibility of selecting postproduction modification approaches. The objective of this review is to summarize strategies to enhance biochar properties relevant to its use in environmental services (e.g., water purification, air/gas cleaning, construction materials, soil amendments) and the corresponding results on the use of this material for these applications. The main methods for enhancing biochar properties for environmental applications reviewed include activation (physical and chemical), oxidation, metal and metal oxide modification, metal-free heteroatom doping, and biological modification. Both modified and unmodified biochars have been used for soil amendments as adsorbents of pollutants in the aqueous phase (e.g., removal of P and N, heavy metals, and organic pollutants), adsorbents of pollutants in the gas phase (e.g., biogas cleaning), as a catalyst, as an additive for improving anaerobic digestion, and as an admixture to cementitious/construction materials, with promising results in all cases. New opportunities for using biochar are being reported as the science of biochar production, modification, and use advances.

Different types of biomasses are utilised for biochar production, but agricultural solid wastes remain a viable feedstock because of its availability and lower cost. This study investigated the possibility of producing biochar from red bell pepper wastes (RBPW) using slow carbonisation (300 and 400 °C) without chemical modification and characterising the produced biochar in an endeavour to elucidate on its potential use for environmental remediation. Proximate analysis, physical and chemical properties of the biomass and biochars were investigated using standard methods and analytical instruments. The yields of biochars from RBPW were found to be 25.8 and 23.5%, respectively, for biochar produced at carbonisation temperatures of 300 and 400 °C. Elemental analysis showed the presence of elements with concentration patterns that followed the order Fe > Na > Ca > K > Mg > Mn > Zn in the biomass and biochars though the biochars had higher concentrations than the biomass. The specific surface areas and pore volumes of both biomass and biochars were found to be low (< 0.706 and 0.0280 cm2/g, respectively) as per the BET results. FTIR results showed the presence of oxygen-containing functional groups on the surface of both biomass and biochars. The surface of biomass had more acidic sites as opposed to biochars which had more basic sites. RBPW has shown typically acceptable chemical, physical and thermal properties for the production of biochar. Further studies are required to understand whether chemical activation would improve their surface properties and the conditions under which they can be used. Graphical Abstract
