“…Slaughterhouse by-products (OF01 and OF07) after anaerobic digestion have been poorly studied as fertilizers [14,40], and they are characterized by a relatively high N tot (4-5%) and low C:N ratio (8-9:1). Therefore, it is not surprising that these OFs released as N bav only a quarter of the N tot added to the soil.…”

Agriculture can play a primary role in the context of nutrients recovery by promoting the use of organic fertilizers (OFs). In order to use them efficiently, it is necessary to predict the nitrogen (N) bioavailability, which is a challenging matter due to the different physical-chemical characteristics of commercially available OFs. This study aims to evaluate hot-water extractable N as a rapid and cheap chemical indicator of bioavailable N. The trial was conducted on nine animal-based OFs obtained from different raw materials and treatment processes. They were fully characterized and the bioavailable N was determined by a 7-week soil incubation experiment. The results showed that hot-water extractable N underestimated bioavailable N in the case of leather meal based OFs; however, a significant linear regression fitting was achieved (R2 = 0.53). The C:N ratio was also assessed, which showed a negative correlation (−0.87) and a better linear regression fitting (R2 = 0.76) with the bioavailable N, but manifested some limitations in the prediction of leather meal based products. This experiment showed that both hot-water extractable N and C:N ratio can provide useful information for farmers in managing this class of OFs.

“…After proper heat treatment, organic wastes are generally transformed into either animal/ fish feed or nutritious organic fertilizer [49]. Drying is a simple technique of heat and mass transfer that allows low-cost recycling of animal waste in agriculture as stated by Bhunia et al [96]. EU Directive 1990/667/EC suggested that drying of biomass waste at 133 • C for 20 min may completely eradicate infectious pathogens from the process end product [97].…”

Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality and improving soil fertility. Soil health and food security are the key elements of Organic Agriculture 3.0. Landfilling and/or open-dumping of animal wastes produced from slaughtering cause environmental pollution by releasing toxic substances, leachate and greenhouse gases. Direct application of animal carcasses to agricultural fields can adversely affect soil microbiota. Effective waste management technologies such as thermal drying, composting, vermicomposting and anaerobic digestion transform animal wastes, making them suitable for soil application by supplying soil high in organic carbon and total nitrogen. Recent agronomic practices applied recycled animal wastes as organic fertilizer in crop production. However, plants may not survive at a high fertilization rate due to the presence of labile carbon fraction in animal wastes. Therefore, dose calculation and determination of fertilizer application frequency are crucial for agronomists. Long-term animal waste-derived organic supplementation promotes copiotrophic microbial abundance due to enhanced substrate affinity, provides micronutrients to soils and protects crops from soil-borne pathogens owing to formation of plant-beneficial microbial consortia. Animal waste-derived organically fertilized soils possess higher urease and acid phosphatase activities. Furthermore, waste to fertilizer conversion is a low-energy requiring process that promotes circular bio-economy. Thus, considering the promotion of soil fertility, microbial abundance, disease protection and economic considerations application of animal-waste-derived organic fertilizer should be the mainstay for sustainable agriculture.

“…(Khalatbari-Limaki et al, 2020). There are efficient technologies available for treating this type of wastewater, including microfilters, green filters, advanced oxidation, membrane treatment, electrocoagulation, and distillation (Musa and Idrus, 2021 ;Brennan et al, 2021 ;Ng et al, 2022), they have not yet become accessible or affordable options for treating municipal SWW in low-income rural communities or those with geographical dispersion, as is the case in Mexico, where 97.7% of the country's total localities are considered rural and classified as having a high marginalization index (Bhunia et al, 2019), this situation is particularly challenging for these places. In Mexico, there are 972 registered facilities dedicated to meat processing, including 117 federal inspection slaughterhouses, 194 private facilities, and 661 municipal ones (SADER, 2023 ;SENASICA, 2023).…”

Wastewater from municipal slaughterhouses remains a persistent issue in the world, owing to its inherent characteristics it has been categorized as one of the most environmentally detrimental water sources. Mexico has 972 registered facilities dedicated to meat processing, so it is necessary to establish the best treatment options in order to achieve efficient control of the wastewater produced, reduce water consumption and enhance the utilization of natural resources. The objective of this study was to estimate the quantities of municipal slaughterhouse wastewater produced in Mexico and to provide information on the legislation applicable to the disposal and discharge of these effluents. It also presents the nature-based solutions that could be applied and that are technically and economically feasible, as well as future opportunities for the sustainable management of this type of wastewater. The state of Jalisco is the largest generator of wastewater and solid waste in the country, and significant progress has been made in the transition of public policies toward a sustainability model nationwide. These advancements are supported by legal foundations, institutional frameworks, and governmental bodies. The competitive advantages of nature-based solutions such as constructed wetlands over other treatment technologies include low operation and maintenance costs, ease of implementation, low energy consumption, and the fact that they are not harmful to nature and receiving bodies. While significant progress has been made in the management and sanitation of slaughterhouse wastewater, challenges persist with regard to the technologies employed (design and operation parameters, scaling up, biochemical processes involved, etc.) which in turn become excellent areas of opportunity for future research.
