The bottom line

The potential role of biochar as a means of sequestering atmospheric carbon has so far been the main focus of attention. However, its virtues are much wider with potential impacts on soil fertility, plant yield and quality and as an additive in livestock feed, biodigesters and other liquid waste disposal systems. More important is the emphasis that biochar has given to the overall concept of the systems approach to utilization of renewable resources and recycling of wastes with maintenance or improvement in soil fertility. Biochar makes most sense when it is derived from a process that aims to optimize the varied characteristics of biomass, to satisfy the major needs of humanity which are food, energy, shelter and a healthy environment. It needs to be produced and used locally for maximum benefits.”
