The production of cement in India is about 200 Million Tonnes per annum. The country, therefore, has potential to utilize spent wash concentrate from the distilleries for coprocessing in cement industry. Based on satisfactory performance of trial run, CPCB has granted regular permission for Coprocessing of few categories of wastes and 25 cement 0
While gravel can be used in concrete and is commonly seen in rough structures as a basic building block, it is more common for a fine type of sand to be used for slurry to keep the mixture as pourable as possible while still retaining some form of thickness. It also helps the concrete from cracking during the shrinking phase of the curing.

Most cement kilns today use coal and petroleum coke as primary fuels, and to a lesser extent natural gas and fuel oil. Selected waste and byproducts with recoverable calorific value can be used as fuels in a cement kiln (referred to as coprocessing), replacing a portion of conventional fossil fuels, like coal, if they meet strict specifications.

Materials like concrete not used at the jobsite and returned to the plant, fine concrete materials from concrete mixer truck washout, process water from concrete washing and production activities, concrete residue on the ground at a concrete plant, etc. So, is that concrete hazardous waste? That''s a bit more of a tricky answer.
Coprocessing carbon in cement kilns burns up the spent carbon. The third method of spent activated carbon disposal is only viable if the material is deemed nonhazardous. If handled correctly, there are no concerns depositing approved, nonhazardous spent activated carbon in an industrial landfill.
