The meat processing industry generates significant quantities of waste, including solid animal by-products (ABPs) and slaughterhouse wastewater (SWW). For instance, based on global meat production in 2020 (approximately 250 million tons), slaughterhouse activities can generate up to 2250 million m³ of SWW and around 375 million tons of ABPs annually.

The selectivity of the colorimetric method for Co(II) determination using the nitroso-R-salt (NRS) in samples with complex matrices has been improved. Interferences caused by Cu(II), Fe(II), Fe(III), Mn(II), Al(III) and Ni(II) ions, which were present in the bioleach ate of lithium-ion batteries, have been solved through the sequential addition of masking agents: acetate, fluoride, ethylenediaminetetraacetic acid (EDTA), and strong acids (HSO).

In apple processing, waste material known as apple pomace amounts to 45% of production volumes. When this residue is stored in open-air for its stabilization and potential uses, Volatile Organic Compounds (VOCs) are produced, resulting in environmental and odor pollution, and must be managed to avoid their impact.
