Encyclopedia > Organic material

"Organic material" or "organic matter" is informally used to denote a material that originated as a living organism; most such materials contain carbon and are capable of decay. They are found in soil and elsewhere, and may include still-living material, such a cell culture. Epithelial cells in culture, stained for keratin (red) and DNA (green) Cell culture is the term applied when cells are grown in a synthetic environment. ...


Strictly speaking, "organic" matter is not necessarily created by living organisms, and living organisms are not made entirely of organic material. The more technically correct term for such material is "biotic." A clam's shell, for example, is an essential component of the living organism, but it is not technically organic. Conversely, urea is an organic substance that can be synthesized without any biological activity. The equation of "organic" with living organisms comes from the scientifically abandoned idea of vitalism that attributed a special force to life that alone could create organic substances, which was first called into question by the abiotic synthesis of urea by Friedrich Wöhler in 1828. Urea is an organic compound of carbon, nitrogen, oxygen and hydrogen, with the formula CON2H4 or (NH2)2CO. Urea is also known as carbamide, especially in the recommended International Non-proprietary Names (rINN) in use in Europe. ... Vitalism is the doctrine that vital forces are active in living organisms, so that life cannot be explained solely by mechanism. ... W̦hler Friedrich W̦hler Friedrich W̦hler (July 31, 1800 - September 23, 1882) was a German chemist, best-known for his synthesis of urea, but also the first to isolate several of the elements. ...

The use of organic materials is high on the agenda of many popular environmental groups. Due to the popular belief that organic materials are environmentally friendly whereas "conventional" materials are not, is often forgotten that fossil fuels and other highly processed organic materials do in fact fall into this category. The phrase environmentally friendly is used to refer to goods or services considered to inflict little harm on the environment. ... Fossil fuels are hydrocarbon-containing natural resources such as coal, petroleum and natural gas. ...


Processed organic material may be called bio-based material. A bio-based material is simply an engineering material made from substances derived from living tissues. ...
