“…Thus, the combination of GHG emissions from charcoal production by kilns in combination with deforestation can result in a net increase of global warming potential [86]. When a sustainable biomass production is ensured, the main sources of GHG emissions occur from thermochemical conversion and raw feedstock processing [11].…”

“…Although CO 2 emissions from biomass and its derivatives are accounted as CO 2 neutral, toxicity, and land acidification of volatile matter can result in net GHG emissions. Based on the emissions, the selection and used technique of the carbonization process is as important as the sustainable biomass production [11]. Previous studies have shown that GHG savings from charcoal fines in metal production can be similar to lump charcoal (≈1780 kg CO 2 -eq.…”

“…Traditional cost and process optimization can be combined by linking environmental calculations for each process step within life cycle analysis. The important aspect of LCA is the system boundary, including processes and production routes which are considered and where the system begins and ends [11]. While a complete LCA evaluates the overall life time of a product (cradle-to-grave), cradle-to-gate approaches are commonly used to describe production of raw materials [8,[11][12][13].…”

“…The cradle-to-gate approach includes the transition phases such as feedstock growth, pretreatment, transport, storage, and postprocessing by metallurgical smelters. However, not all aspects of sustainability can be considered within LCA [11]. Technical issues caused by the different properties and the economics of renewable reductants can play a significant role in replacing fossil fuel-based reductants [14,15].…”

This study examined the literature on life cycle assessment on the ferromanganese alloy production route. The environmental impacts of raw material acquisition through the production of carbon reductants to the production of ferromanganese alloys were examined and compared. The transition from the current fossil fuel-based production to a more sustainable production route was reviewed. Besides the environmental impact, policy and socioeconomic impacts were considered due to evaluation course of differences in the production routes. Charcoal has the potential to substantially replace fossil fuel reductants in the upcoming decades. The environmental impact from current ferromanganese alloy production can be reduced by ≥20% by the charcoal produced in slow pyrolysis kilns, which can be further reduced by ≥50% for a sustainable production in high-efficient retorts. Certificated biomass can ensure a sustainable growth to avoid deforestation and acidification of the environment. Although greenhouse gas emissions from transport are low for the ferromanganese alloy production, they may increase due to the low bulk density of charcoal and the decentralized production of biomass. However, centralized charcoal retorts can provide additional by-products or biofuel and ensure better product quality for the industrial application. Further upgrading of charcoal can finally result in a CO2 neutral ferromanganese alloy production for the renewable power supply.

The state of California could play an important role in emerging markets for biochar, due in part to the availability of low‐value biomass resources and their potential for use in agriculture sector. In this study, we assess the scale of production and use, and comment on potential markets for biochar in California. We explore various sectors for the application of biochar produced from local biomass using surveys and a market‐sizing approach. A market‐oriented approach for biochar innovation and the ecosystem around a biochar producer is also discussed. Next, we identify barriers to biochar market success in the present and the near future based on a survey of local producers. Among the barriers analyzed, access to capital investment for scale‐up is the biggest barrier experienced by a majority of producers, followed by market and demand. When grouped under different categories, the extent of barriers decreased in the order: market > scale‐up > technical > socio‐political > environmental. Most producers anticipate that revenues from carbon offset credits would help them scale up their facilities and expand the biochar market. In the near future, soil‐based applications of biochar could be the most likely market for biochar, followed by filtration, livestock feed, and manure management. As the industry evolves, rewarding carbon credits, increasing awareness and improving production processes are expected to help commercialize biochar. Finally, we offer recommendations to promote the growth of biochar in California. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd
