“…Meanwhile, discarding of SCR as waste is a potential environmental problem because it is highly susceptible to putrefaction [6,7]. The environmental problems arising from the massive generation of residues have been attracting considerable attention [8]. In fact, SCR also has high moisture content (70%-80%), which makes it difficult to handle and expensive to dry by conventional means [9].…”

The production of soybean products has been increasing throughout the world, and there has been a corresponding increase in the quantity of soybean curd residue (SCR) being thrown out. The dumping of SCR has become a problem to be solved due to its contamination to the environment. SCR is rich in fiber, fat, protein, vitamins, and trace elements. It has potential for value-added processing and utilization; options that simultaneously hold the promise of increased economic benefit as well as decreased pollution potential for the environment. The objective of this study is to fully investigate, review, and summarize the existing literature in order to develop a comprehensive knowledge base for the composition and reuse of SCR. It is evident from the literature survey that SCR shows good potential as a functional food material. However, there are several drawbacks to the use of SCR and corresponding solutions presented in this paper.

“…Slaughterhouses and meat processing industries generate large amounts of wastes and by-products, e.g. carcasses, feet, offal, hides, bones and blood, corresponding to 40-50% of the total animal weight slaughtered (Cuadros et al, 2011;FAOSTAT, 2012). Anaerobic digestion of organic wastes is a highly sustainable process, since it combines waste treatment with energy production in the form of biogas and nutrients recycling.…”

Raw and pre-treated greaves and rinds, two meat-processing wastes, were assessed for biochemical methane potential (BMP). Combinations of temperature (25, 55, 70 and 120 °C), NaOH (0.3 g g(-1) waste volatile solids) and lipase from Candida rugosa (10 U g(-1) fat) were applied to promote wastes hydrolysis, and the effect on BMP was evaluated. COD solubilisation was higher (66% for greaves; 55% for rinds) when greaves were pre-treated with NaOH at 55 °C and lipase was added to rinds after autoclaving. Maximum fat hydrolysis (52-54%) resulted from NaOH addition, at 55 °C for greaves and 25 °C for rinds. BMP of raw greaves and rinds was 707±46 and 756±56 L CH4 (at standard temperature and pressure) kg(-1)VS, respectively. BMP of rinds improved 25% by exposure to 70 °C; all other strategies tested had no positive effect on BMP of both wastes, and anaerobic biodegradability was even reduced by the combined action of base and temperature.

“…Abattoirs generate an enormous quantity of waste products in the form of solid and liquid wastes which are responsible for severe environmental degradation if not well handled [72]. The usage of abattoir wastes as secondary fuel through thermal recycling in power plants has been reported to be achievable [73].…”

The Potential of Animal By-Products in Food Systems: Production, Prospects and Challenges

Abstract:The consumption of animal by-products has continued to witness tremendous growth over the last decade. This is due to its potential to combat protein malnutrition and food insecurity in many countries. Shortly after slaughter, animal by-products are separated into edible or inedible parts. The edible part accounts for 55% of the production while the remaining part is regarded as inedible by-products (IEBPs). These IEBPs can be re-processed into sustainable products for agricultural and industrial uses. The efficient utilization of animal by-products can alleviate the prevailing cost and scarcity of feed materials, which have high competition between animals and humans. This will also aid in reducing environmental pollution in the society. In this regard, proper utilization of animal by-products such as rumen digesta can result in cheaper feed, reduction in competition and lower cost of production. Over the years, the utilization of animal by-products such as rumen digesta as feed in livestock feed has been successfully carried out without any adverse effect on the animals. However, there are emerging gaps that need to be further addressed regarding the food security and sustainability of the products. Therefore, the objective of this review highlights the efficacy and effectiveness of using animal by-products as alternative sources of feed ingredients, and the constraints associated with their production to boost livestock performance in the industry at large.
