Abstract

Highlights: Biochar systems have a direct and indirect link to the water-energy-food nexus. Bibliometric trends reveal a research gap where novel modeling framework is needed. Synthesis of biochar systems and networks presents key PSE research challenges. Economic viability of biochar can be assessed with the aid of lifecycle costing. Abstract : Biochar application to soil is a potentially scalable carbon management strategy with the capability of achieving negative greenhouse gas emissions. In addition, biochar is also linked to the water-energy-food nexus (WEFN) through its potential to modify soil properties to improve agricultural productivity. Potential benefits include increased yield and reduced demand for water, fertilizers and other inputs. However, the current literature on biochar is highly fragmented, with a significant research gap in system-level analysis to synchronize production, logistics and application into a sustainable carbon management strategy. Process systems engineering (PSE) can provide a framework to allow the potential benefits of biochar systems to be optimized. This article gives an overview of biochar as a strategy to address carbon management and WEFN issues, reviews relevant scientific literature, analyzes bibliometric trends, and maps potential areas for the application of PSE to the planning of large-scale biochar systems.
