Coal is the largest and most widespread fuel resource providing 23 per cent of the worlda s energy. However widespread concern about environmental emissions from coal has started to limit the growth in use of this important energy source.
While metallurgical coal and thermal coal have similar geologic origins, their commercial markets and industrial uses are vastly different.
Thermal coal or steaming coal is burned for steam to run turbines to generate electricity either to public electricity grids or directly by industry consuming electrical power (such as chemical industries, paper manufacturers, cement industry and brickworks). During power generation the coal is ground to a powder and fired into a boiler to produce steam to drive turbines to produce electricity.
8% protein is primarily used for animal feed due to its balanced nutritional profile and high starch content. It typically contains minimum 8% crude protein on a dry basis, moisture not exceeding 14%, broken kernels below 5%, and foreign matter under 2%. The test weight is generally 70-72 kg/hl, with heat-damaged kernels not exceeding 0.5%. It complies with international safety standards for mycotoxins and aflatoxins, and can be supplied as GMO or Non-GMO
