This study critically analyzes the life cycle assessment of biochar production from different sources and technologies, demonstrating the great potential of biochar in circular economy for carbon-efficient resource circulation, climate change mitigation, and economic sustainability.
What are the main findings? Biochar is considered a black porous and carbon-rich matter; Biochar is a promising source of alternative energy. What is the implication of the main finding? It can be concluded that the costs are closely related to the technologies used in biochar production and also to the feedstock used. Climate change and environmental sustainability are among the most prominent issues of today. It is increasingly fundamental and urgent to develop a sustainable economy, capable of change the linear paradigm, actively promoting the efficient use of resources, highlighting product, component and material reuse. Among the many approaches to circular economy and zero-waste concepts, biochar is a great example and might be a way to push the economy to neutralize carbon balance. Biochar is a solid material produced during thermochemical decomposition of biomass in an oxygen-limited environment. Several authors have used life cycle assessment (LCA) method to evaluate the environmental impact of biochar production. Based on these studies, this work intends to critically analyze the LCA of biochar production from different sources using different technologies. Although these studies reveal differences in the contexts and characteristics of production, preventing direct comparison of results, a clear trend appears. It was proven, through combining life cycle assessment and circular economy modelling, that the application of biochar is a very promising way of contributing to carbon-efficient resource circulation, mitigation of climate change, and economic sustainability.
