Biochar can be produced from almost as many types of feedstock as there are types of biomass including agricultural wastes, rice husks, bagasse, paper products, animal manures, and even urban green waste. However, the focus is placed on the use of “true wastes” in order to minimize disruption to local carbon recycling and energy resources recovery.
biochar is best thought to manage carbon for climate change mitigation purposes combined with a downstream application to improve soil quality and for its agricultural effects.
Biochar is being promoted as a climate change mitigation tool as it can increase soil carbon sequestration and reduce soil GHG emissions when applied as a soil amendment. Biochar production and burial remove carbon dioxide directly from the atmosphere through uptake by plants, allowing, in principle, an actual reduction of atmospheric carbon dioxide levels. Also, the production and burial of biochar allow the sequestration of carbon in the soil at the same time as providing fertilizer. A recent expert assessment estimates that biochar could sequester 0.5–2 GtCO2 per year by 2050 at a cost of $30–120 per ton of CO2.
As a soil amendment, biochar is part of a process that can simultaneously produce renewable biofuels, sequester carbon, and improve degraded soils. Promoting soil carbon sequestration through recommended management practices has the potential to mitigate 5% to 15% of global fossil fuel emissions.
Pyroltech offers a solution to reduce carbon foot print with uptake carbon dioxide by plants in process of turning waste into energy.
