Biochar & carbon sequestration

Abstract

The traditional answer to the question of controlling the growth of global warming involves reducing emissions of greenhouse gases like CO2. However, developed and developing countries have difficulty in adopting measures to reduce use of fossil fuels in the short or medium term. The world is currently exceeding the rate of greenhouse gas emissions. Consequently, it is urgently necessary to remove carbon dioxide from the atmosphere. Extensive research efforts in science and technology are underway to develop approaches to capture and sequester carbon. In this work we deal with the different processes proposed, but with great emphasis on the process of biochar production by pyrolysis of biomass which copies the methodology of Terra Preta de Índios da Amazonia.
