Given that the problem of contaminated soil continues to grow, the development of effective control and remediation measures has become imperative, especially for heavy-metal-contaminated soil. Biochar and modified biochar are eco-friendly and cost-effective remediation materials that are widely used in the remediation of contaminated soil. This review provides an overview of the different raw materials used in the preparation of biochar as well as the modification of biochar using various synthesis methods, highlighting their differences and providing recommendations for biochar and modified biochar as applied toward ameliorating pollution in soil contaminated by heavy metals. We also explore the effects of the physicochemical properties of raw materials, pyrolysis temperature, additives, and modification methods on the properties of the resulting biochar and modified biochar, and systematically present the types of soil and operating factors for repair. Moreover, the mechanisms involved in remediation of heavy-metal-contaminated soil by biochar and modified biochar are outlined in detail, and include adsorption, complexation, precipitation, ion exchange, and electrostatic attractions. Finally, the corresponding monitoring technologies after remediation are illustrated. Future directions for studies on biochar and modified biochar in the remediation of contaminated soil are also proposed to support the development of green environmental protection materials, simple preparation methods, and effective follow-up monitoring techniques.

“…This discount rate is consistent with those used in other biochar economic analysis. Discount rates range from 7% to 16.5% (Haeldermansa, Campionc, Kuppensc, Vanreppelena, Cuypersd, & Schreurs, 2020) (Sahoo, Bilek, Bergman, & Mani, 2019). Campbell, Anderson, Daugaard, & Naughton, (2018) used a 10% discount rate as their base rate, with an uncertainty distribution rate of 4% minimum rate and a 16% maximum rate.…”

“…Monte Carlo is a mathematical simulation that calculates the probability of different outcomes based on multiple iterations of the model. The Monte Carlo probability analysis is well understood and is used to complete an economic analysis in several biochar studies (Campbell et al, (2018); Dickinson et al (2015); Haeldermansa et al (2020)). The analysis establishes a range of estimates: minimum (most pessimistic), base (most likely), and maximum (most optimistic) for each variable.…”

This paper measures the benefits and costs of using biochar, a carbon sequestration technology in the British Columbia (BC) wine industry. It was found that the use of biochar, produced from wine industry waste, can reduce greenhouse gas emissions, and make a significant economic contribution to the BC wine industry. An economic model was developed to calculate the value-added from each of the three sectors that comprise the BC Wine industry value chain. The model uses biochar, produced from grape prunings and pomace, as a soil amendment in the vineyards. Grapes produced from these vineyards are used to produce wine. The assumptions for each variable used in this study are drawn from the literature and prior research by the authors. In addition to achieving the industry’s sustainability goals, each sector of the wine value chain is potentially profitable, however producing biochar as a profitable independent business is likely minimal compared to what could be achieved along the value chain with increased yields of the same quality. Biochar as a soil amendment is a long-term investment for farmers with results best assessed after multiple years. Future research is needed to better understand the biochar production process as an integral part of the BC wine industry, the carbon sequestration benefits, the specific increases in long-term grape yields and wine production. Also, the industry willingness to re-evaluate and change present industry practices, and other important benefits that can be derived from marketing climate friendly wine to BC consumers needs to be understood.

“…For example, numerous studies have investigated the use of biochar as a plant growing substrate [26][27][28][29]. However, production costs for biochar and other components must be systematically assessed and compared with peat, as recommended by Haeldermans et al [30], who evaluated the techno-economic viability of biochar production. Charcoal waste resulting from the incomplete burning of wood in furnaces for heating water for industrial boilers in poultry processing plants reportedly has similar properties to biochar and peat, and might be used to produce desirable organic amendments [22].…”

Plant growing substrates obtained by composting agro-industrial waste can serve as organic soil amendments. However, it is crucial to determine the maturity and quality of organic amendments before their application to soil. This study aimed to evaluate the suitability of compost obtained from poultry wastes combined with five different vegetal residues (tree trimmings, sugarcane bagasse, sawdust, cotton residues, and Napier grass) as growth media for container-grown Giant of Italy parsley. Fourier-transform infrared and laser-induced fluorescence spectra were used to characterize the humification extent in composts before and after the addition of charcoal at five inclusion rates (0%, 15%, 30%, 45%, and 60%, weight basis). Spectroscopic measurements identified absorption bands between 1625 and 1448 cm−1 specific to each of the 25 organic amendments evaluated. The most suitable amendments (composts made from sawdust and sugarcane bagasse) were associated with O–H stretching of phenols and aromatic rings. Charcoal addition to composts changed some of their physical characteristics, leading to increased nutrient availability in some cases. Experimental and calculated dry matter yield were compared via multiple linear regression and simple non-linear regression as a function of the spectroscopic and physicochemical (N, P, K, pH, EC, C, HLIF, C:N, CEC, HA:HA) properties of the organic amendments. Regression models accurately assigned high yields to the sawdust- and bagasse-based composts and low yields to the Napier grass- and cotton-based composts. Electrical conductivity (EC) was the main factor limiting potted-parsley productivity, an indication that efficient management of charcoal rate and compost EC levels can aid in predicting parsley yield.
