Biochar is a name for charcoal when it is used for particular purposes, especially as a soil amendment. Like all charcoal, biochar is created by pyrolysis of biomass. Biochar is under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions.[1] Biochar thus has the potential to help mitigate climate change, via carbon sequestration.[2] Independently, biochar can increase soil fertility, increase agricultural productivity and provide […]
Biomass is biological material derived from living, or recently living organisms. It most often refers to plants or plant-derived materials which are specifically called lignocellulosic biomass.[1] As a renewable energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different […]
The biological process of synthesis of organic materials from carbon dioxide and water utilizing sunlight as the energy source and with the aid of chlorophyll and other associated biological structures. (http://www.ic.ucsc.edu/~wxcheng/envs23/lecture11/global_C_cycle.htm)
Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen (or any halogen). It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The word is coined from theGreek-derived elements pyro “fire” and lysis “separating”. Pyrolysis is a type of thermolysis, and is most commonly observed in organic materials exposed to high temperatures. It is one of the processes involved in charring wood, starting at 200–300 °C […]
The energy-generating biological process which involves oxidation of organic compounds into carbon dioxide, water, and other compounds. (http://www.ic.ucsc.edu/~wxcheng/envs23/lecture11/global_C_cycle.htm)
This website explains with excellent infographics what the short and long term carbon cycles are in relation to increasing atmospheric carbon. Composite from National Research Council and UNEP: Quoting OnlyZeroCarbon.org: It is the carbon cycle that determines the fact that global warming, climate change, and ocean acidification cannot ever stabilize without civilization stopping constantly […]
A process moves carbon from the long-term carbon cycle into the short term carbon cycle, specifically into the atmosphere.
Carbon positive is the transfer of carbon from biomass into the atmosphere.
A process that takes carbon in the form of biomass and moves it from the short-carbon cycle to the long-term carbon cycle.
Carbon negative is the movement of carbon from the atmosphere into biomass ( plants ) as a normal part of the short-term carbon cycle
