Abstract Biochar possesses unique characteristics, including a substantial surface area, high carbon content, sufficient capacity for cation exchange, and robust structure. However, biochar contains hazardous pollutants like volatile organic compounds that harm soil properties functionality. Although several studies on production from various feedstocks have been undertaken in recent years, issues about feedstock preparation, economic feasibility, influencing factors, the proper utilization of processes need to be addressed. This paper thus addresses these by providing potential solutions identified through comprehensive review. Slow pyrolysis lignocellulosic biomass Acacia nilotica yields 20 52 wt% at temperatures residence times. yield varies 29 48.3 when waste tires corn stalks are rapidly pyrolyzed higher shorter periods. Torrefaction algal moderate with different times can result 50–60 wt%. variability heterogeneity pose challenges affecting biochar's quality properties. Given its widespread use sequestration, remediation, wastewater purification, composting, mechanisms environmental usage investigated.

Abstract Biochar, a carbon-rich material produced through the pyrolysis of organic biomass, has gained increasing attention as sustainable soil amendment due to its potential enhance health, improve agricultural productivity, and mitigate climate change. This review explores multifaceted benefits biochar, including ability sequester carbon for long periods, thereby reducing atmospheric greenhouse gases. Biochar’s unique properties, such porous structure, high cation exchange capacity, nutrient retention capabilities, significantly fertility, water-holding microbial activity. These improvements increase crop resilience against drought, erosion, loss, supporting climate-resilient systems. Additionally, biochar’s application can lower nitrous oxide methane emissions from soils, further contributing change mitigation. However, effectiveness biochar is influenced by factors feedstock type, conditions, rates. Understanding these variables crucial optimizing biochar's use in different types environmental conditions.

Life cycle assessment (LCA) has been widely used to evaluate the carbon negativity and environmental impacts of dioxide removal (CDR) pathways. Various monitoring, reporting, verification (MRV) protocols have developed assess credits CDR projects within voluntary compliant markets. Many MRV incorporate life thinking, LCA methods, data. This perspective examined recent studies published by main registries, focusing on four critical land-based methods: bioenergy combined with capture storage, biochar, enhanced rock weathering, afforestation reforestation. We compared accounting impact methods employed in these identify their methodological similarities differences. Our analysis reveals that community can support providing insights into baselines, additionality, uncertainty, multifunctionality, safeguards, holistic emission factors, overlooked pools. recommend future research prioritize timing, permanence, scaling, dynamic modeling for CDR. Addressing co-benefit land use change will further benefit both development. Collaboration between communities is essential developing robust frameworks markets policymaking.
