“…However, current trends are exploring recycling strategies for these wastes. These include their use in biodiesel production [62], hydrogen generation [63], and soap manufacturing [64]. Furthermore, they undergo processing to yield meals enriched with protein and fat, suitable for animal feed [65], as detailed below.…”

This review delves into the processing of tannery solid waste, emphasizing fleshings and chromium-tanned leather waste. This paper centers on fat recovery, chromium elimination, and protein preservation, aiming to make them apt for animal consumption. This paper also assesses the potential of introducing such recycled products to the global market. Drawing on the literature from the past two decades, sourced comprehensively from Scopus and Web of Science, 36 articles were selected because of their significant contributions from leather production powerhouses such as India and Brazil. Fleshings have shown immense potential as animal feed, and the extraction of tallow and collagen from rawhide trimmings yields up to 98% and 93%, respectively. Fermented tannery fleshings, notably with Enterococcus faecium HAB01, also demonstrate strong antioxidant capabilities. The overarching consensus emphasizes the need for rigorous purification when dealing with chromium-containing wastes, addressing concerns tied to Cr (III) and Cr (VI). Furthermore, raw tannery fleshings stand out as a sustainable, cost-effective, and globally marketable solution for animal feed production.

“…In addition to meat, a slaughterhouse produces various other organs and tissues, such as fatty tissues, horns, hoofs, feet, skull, entrails and internal organs, which are mechanically separated from the meat (Ockerman et al, 2017). Approximately 45-60% of an animal's total weight is considered suitable for human consumption, while the remaining portion is considered waste (Chowdhury et al, 2022). The waste obtained from this sector is known for its complex nature, mainly due to factors such as its pathogenic nature, high water content, propensity for rapid auto-oxidation, and elevated levels of enzymatic activity (Jayathilakan et al, 2012).…”

Food wastage occurs throughout the entire food chain, starting from agricultural production and continuing through post-harvest handling, storage, production, distribution, consumption and disposal. Food wastage not only affects food security but also has detrimental consequences for the global economy and the environment. Food loss and waste occur throughout the meat supply chain. According to literature data, 23% of meat production is lost and wasted across all stages of the food chain, with the highest share attributed to the consumption phase. Improved farming practices, animal health management, efficient transport systems, proper storage and handling at processing and retail levels, and consumer education on responsible consumption can all contribute to reducing food loss and waste in the meat sector.

“…Thus, it is essential to have an efficient treatment system so that the high blood content of organic matter is removed, and it should be according to the standards and requirements approved by environmental legislation for preventing ecosystem damage. Blood, a critical pollutant dissolved in slaughterhouse wastewater, shows a COD of 375,000 mg/L [40]. Also, slaughterhouse wastewater encompasses high concentrations with a high FC load in the wastewater.…”

The slaughterhouse industry produces large amounts of highly polluted wastewater which needs to be treated before being discharged water. Thus, this work was conducted to investigate the feasibility of treating slaughterhouse wastewater using combined chemical coagulation and electro-Fenton methods. We studied the effect of process parameters such as polyaluminum chloride (PAC) concentration (25, 50, 75, 100 mg/L) for chemical coagulation and hydrogen peroxide concentration (500, 1000, 1500, 2000, 2500, 3000, 4000 mg/L), the pH of the solution (3, 5, 7, 10), and the reaction time (5, 10, 15, 30, 45, 75, 120 min) and the voltage (10, 20, 30, 40 V) on the removal of chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), total Kjeldahl nitrogen (TKN), and fecal coliforms (FC). The optimum removal efficiency for the electro-Fenton process was obtained at PAC = 75 mg/L, reaction time = 75 min, pH = 3, H2O2 = 2500 mg/L, and V = 20 V, which resulted in the removal efficiency of 89.55% for COD, 88.88% for BOD, 91.27% for TSS, 69.23% for TKN, and 100% for FC. The findings demonstrated that combined chemical coagulation and electro-Fenton processes effectively and efficiently treat slaughterhouse wastewater. The results of this research can be used by competent authorities to increase the efficiency of slaughterhouse wastewater treatment and to protect the environment.
