Diester and Aquazole™: Fuels referred to as biofuels. Aquazole™ is a water-diesel fuel emulsion.
Digestate: “Digested” waste or residue from the anaerobic digestion of organic waste. Digestate contains excess bacteria, non-degraded organic mater and mineralized material. After treatment, it can be used as compost.
Dioxins: The generic name for a family of chlorinated organic substances that appear during the combustion process. Dioxins are given off by the combustion of chlorine-containing products (cement works, manufacture of herbicides and pesticides, paper pulp bleaching, foundries, metals, steel making, waste incinerators, etc.). They can also be of natural origin and sources that are difficult to evaluate (forest fires and volcanic eruptions, for example) as well as diffuse sources (such as open air combustion: garden fires, open fireplaces, pit fires, etc.). For incineration, the efforts made to boost environmental protection, the closing of outdated plants and new gas scrubbing techniques have already reduced this sector’s emissions by about 70%. Of the 210 known dioxins, 17 are considered as toxic.
District heating and air conditioning network: Comprised of a central production unit and a network of pipes to supply public and private buildings (schools, hospitals, offices and dwellings) with heating, hot water and air conditioning
