Biochar is a carbon rich solid material resulting from the pyrolysis of biomass under oxygen-free and low temperature conditions. Although most research is directed towards the application of biochar to soils, there are several other biochar properties that render it a suitable candidate for non-soil applications. A growing number of studies have tested biochar as a composite in building materials, as a hazardous substance adsorbent in drinking water and wastewater, and as a component in filters for indoor air quality and storm water management. The potential to utilize biochar for various applications depends on its properties. For example, biochar with high electrical conductivity, porosity and stability at lower temperatures is preferred as electrodes material in microbial fuel cells.]

Biochar containing relatively high structural bound oxygen groups is preferred in direct carbon fuel cells. On the other hand, biochars with increased particle strength, hydrophobicity and high surface area are suitable candidates for the development of reusable catalysts for chemical reactions. These new high-value applications are still in their infancy, and further research and development is needed to reach commercialization. Optimum reaction conditions for producing biochar are not always the same and reproducibility is often not satisfactory, even when the same biomass is used and the same production conditions are present. This book on non-soil biochar applications aims to highlight the diversity of biochar as a multi-functional material and introduce some new and emerging applications to the wider scientific community. It will act as a reference document to all groups and individuals working or interested in biochar research and will be a valuable contribution to existing published literature.

Reviews

“Biochar may well become the key material for the future bio-based economy. There is no other material promising such versatile use scenarios while sequestering carbon and avoiding greenhouse gas emissions. This is the first book that focuses entirely on the new non-agronomic application of biochar. It is designated to become a trendsetter for industry and material science.” – Hans-Peter Schmidt, Ithaka Institute for Carbon Strategies, Ayent, Switzerland

“Biochar, the carbonization product of pyrolysis, has been attracting increasing attention due to its versatile functions. Research on this carbon-enriched material started about 20 years ago, spurred on by the growing body of knowledge on anthropogenic soils such as the Terra Preta do Indio in Amazonia. The high level and age of black carbon in these fertile soils suggested that soil application of biochar may be a promising way for both long-term carbon sequestration and soil improvement. Today, non-soil biochar applications come to the foreground and the examples presented in this book give a broad and valuable overview about new technologies and application forms. Besides its high sorption capacity for contaminants, biochars have a high innovation potential as new materials, such as supercapacitors and catalysts.” – Jürgen Kern, Leibniz Institute for Agricultural Engineering and Bioeconomy, Potsdam, Germany

“In the past couple of years more and more research is being conducted on the non-agricultural uses of biochar. This book offers a concise overview of the exciting potential and possibilities for using biochar to address some of the pressing ecological and environmental issues facing us today.” – Francesco Tortorici, Founder of Olympic Biochar, Port Townsend WA, USA
