Some authors have investigated the effect of limestone industrial wastes (for example, by-products obtained from paper pulp and steel industries) on forest soils, using them as amendments, given the importance of that re-use in the reduction of environmental impacts [20, 21, 22, 23].
Main feedstocks are solid wastes, for example, agricultural, municipal, and food industrial wastes, and wastewater, for example, industrial and municipal wastewater.
Several physicochemical and biological treatment approaches have been applied for the degradation and detoxification of olive mill wastes, for example, implementation of advanced oxidation systems, aerobic biotreatment, and anaerobic digestion [ 21, 26– 28], although the review of treatment technologies for both OMW and TPOMW is beyond the scope of this paper.

RRMs can be any kind of renewable waste, for example, agricultural waste, municipal waste, and so on, or special (energy) crops produced specifically to be used for this purpose, for example, switchgrass cultivated and produced especially for biofuels.
"We start with diamond waste (for example, [from] the abrasive industry), but we developed a proprietary process (that's of course highly scalable and economical) to purify and engineer the diamond waste into dust," a company spokesperson explained.
Some degree of food waste — plate waste, for example — is unavoidable, of course.
