korkohiiliset

Korkohiiliset is a Finnish term used to describe substances, materials or systems that have a high carbon content. The name is a descriptive label, literally meaning “high-carbon,” and is employed across several scientific disciplines to indicate a pronounced presence of carbon in the material, with implications for energy, chemistry and carbon cycling.

In geology and energy research, korkohiiliset materials include coal types such as lignite and bituminous coal, as well as charred products. These materials are characterized by relatively high fixed carbon content and energy density, though they may vary in moisture and mineral matter. The concept is used to discuss how carbon content influences calorific value, combustion behavior and emissions.

In soil and ecological sciences, korkohiiliset soils refer to substrates with elevated soil organic carbon stocks. Such soils are important for carbon sequestration and soil fertility. Peatlands and certain mineral soils can accumulate substantial amounts of organic carbon and may be described as korkohiiliset in climate and land-management discussions.

In waste management and materials science, carbon-rich fractions from biomass residues, municipal waste, or char-forming processes may be labeled korkohiiliset when their carbon content is sufficiently high to affect processing pathways such as composting, anaerobic digestion, or gasification.

Limitations: the term is not a formal chemical or geological category, but a descriptive label used in Finnish literature to indicate high carbon content. See also: hiili, karbonaatit, maaperähiili.
