“…Wastewater is rich in various pollutants, both organic (blood, fat, manure, undigested stomach contents, meat, and meat extracts) and inorganic from cleaning chemicals needed for good hygiene practices (CAC, 2020). Aleksić et al (2020) performed an interesting study on water consumption and wastewater characteristics of the Serbian meat slaughtering industry. Their study covered 41 slaughterhouses, revealing that more than half have no wastewater treatment and that wastewater quality in some of the observed objects exceeded prescribed legal limits for chemical and biochemical oxygen demands mainly due to the presence of organic matter such as blood, tallow, and mucosa.…”

“…Six slaughterhouses showed TSS values exceeding the allowable limits, while five slaughterhouses showed FOG (fats, oil, and grease) exceeding the allowed limit values. These high effluent concentrations can lead to the development of sludge deposits and anaerobic conditions when untreated wastewater is discharged in the aquatic environment [12]. The standard levels and limit values of organic constituents (COD, BOD, TSS, and FOG) considered here were the ones prescribed by the World Bank Group, the Council of the European Communities, and the Republic of Serbia.…”

Commercialization in the meat-processing industry has emerged as one of the major agrobusiness challenges due to the large volume of wastewater produced during slaughtering and cleaning of slaughtering facilities. Slaughterhouse wastewater (SWW) contains proteins, fats, high organic contents, microbes, and other emerging pollutants (pharmaceutical and veterinary residues). It is important to first characterize the wastewater so that adequate treatment techniques can be employed so that discharge of this wastewater does not negatively impact the environment. Conventional characterization bulk parameters of slaughterhouse wastewater include pH, color, turbidity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total organic carbon (TOC), total suspended solids (TSS), total nitrogen (TN), total phosphorus (TP), and coliform counts. Characterization studies conducted have revealed the effects of the pollutants on microbial activity of SWW through identification of toxicity of antibiotic-resistant strains of bacteria. Due to the high-strength characteristics and complex recalcitrant pollutants, treatment techniques through combined processes such as anaerobic digestion coupled with advanced oxidation process were found to be more effective than stand-alone methods. Hence, there is need to explore and evaluate innovative treatments and techniques to provide a comprehensive summary of processes that can reduce the toxicity of slaughterhouse wastewater to the environment. This work presents a review of recent studies on the characterization of SWW, innovative treatments and technologies, and critical assessment for future research.

“…The wastewater produced by the meat processing industry has increased tremendously in recent years (Aleksic et al 2020 ). According to the Food and Agriculture Organization (FAO) of the United Nations (FAO 2021 ), the demand for broiler chicken and meat is growing faster than any other meat type.…”

Slaughterhouse and wet market wastes are pollutants that have been always neglected by society. According to the Food and Agriculture Organization of the United Nations, more than three billion and nineteen million livestock were consumed worldwide in 2018, which reflects the vast amount and the broad spectrum of the biowastes generated. Slaughterhouse biowastes are a significant volume of biohazards that poses a high risk of contamination to the environment, an outbreak of diseases, and insecure food safety. This work comprehensively reviewed existing biowaste disposal practices and revealed the limitations of technological advancements to eradicate the threat of possible harmful infectious agents from these wastes. Policies, including strict supervision and uniform minimum hygienic regulations at all raw food processing factories, should therefore be tightened to ensure the protection of the food supply. The vast quantity of biowastes also offers a zero-waste potential for a circular economy, but the incorporation of biowaste recycling, including composting, anaerobic digestion, and thermal treatment, nevertheless remains challenging.
