Image by/from Hadhuey at German Wikipedia Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are fibers about 5 to 10 micrometers (0.00020-0.00039 in) in diameter and composed mostly of carbon atoms. Carbon fibers have several advantages: high stiffness, high tensile strength, high strength to weight ratio, high chemical resistance, high-temperature tolerance, and low […]

The carbon cycle is that part of the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth. Other major biogeochemical cycles include the nitrogen cycle and the water cycle. Carbon is the main component […]

Image by/from Diagram adapted from U.S. DOE, Biological and Environmental Research Information System. A carbon sink is anything, natural or otherwise, that accumulates and stores some carbon-containing chemical compound for an indefinite period and thereby removes carbon dioxide (CO2) from the atmosphere. These sinks form an important part of the natural carbon cycle. An overarching […]

Image by/from Tommaso.sansone91 Carbon capture and storage (CCS) is a process in which a relatively pure stream of carbon dioxide (CO2) from industrial sources is separated, treated and transported to a long-term storage location.: 2221  For example, the carbon dioxide stream that is to be captured can result from burning fossil fuels or biomass. Usually the […]

Image by/from Tommaso.sansone91 Carbon emission trading (also called emission trading scheme (ETS) or cap and trade) is a type of emission trading scheme designed for carbon dioxide (CO2) and other greenhouse gases (GHG). It is a form of carbon pricing. Its purpose is to limit climate change by creating a market with limited allowances for […]
