Meat industry generates various wastes such as effluent, emissions and solid wastes that pose environmental and health problems. The effluent released from the meat industries finds its way into the natural water resources and degrade the water quality. The solid wastes of meat industry create a public nuisance by way of foul smell if it is not handled properly. The effluents, as well as solid wastes of meat industries, are possible sources of pathogens that are hazardous to human health. Waste minimization, segregation of wastes and treatment, processing of wastes to make possible recoveries of by-products and the final disposal are the basic steps for containment of pollution from the meat industry. The effluent treatment technologies include primary treatment, secondary treatment and tertiary treatment. Composting, biomehtanation, rendering, incineration and burial are the processes for disposing of the solid wastes generated by meat industries. Appropriate treatment process is selected considering the level of pollution, mode of disposal and the environmental standards. The treatment and processing of meat industry wastes minimize the pollution problems and also give scope for the recovery of by-products such as bone and meat meal, tallow, methane and manure that have commercial values. The meat industries also generate odours that are required to be contained using suitable control devices. The paper seeks to give an overview of the pollution control technologies currently in use for the treatment of effluents and solid wastes, and possible recovery of by-products.

Water Pollution control is offered to undergraduate students whose major is Environmental Engineering, to let students know basic knowledge and control technologies of water pollution, so that they can solve problems on water treatment. As one of the main special courses, it requires to be constructed to keep it up-to-date with currents wastewater treatment technologies. This paper analyzed the current conditions of this course. In addition, it described construction process and effects, including adjustment of the teaching content, improvement of teaching methods, revision of teaching mode, compiling of test database and exercise database and performance of experiments in water pollution control.

Molasses based distilleries in India are now classified as ‘Red Category’ because of the pollution caused by vinasse. The stringent norms being enforced by the pollution control authorities have posed many technical challenges and resulted in the development of advanced and cleaner technologies for effective and economical disposal of vinasse. There has been a shift from the end of pipe treatment to an integrated waste management in order to achieve zero liquid discharge. Anaerobic treatment to generate biogas, aerobic surface composting to manufacture bio-compost and reverse osmosis or multiple effect evaporation systems for concentration of vinasse are now well established. Advanced technologies such as concentrated vinasse incineration, and co-processing of vinasse in cement plants are also being investigated. This paper presents an overview of the latest technologies employed for fermentation and distillation, advantages and limitations of the various effluent treatment technologies and prospects for implementation of emerging technologies. The paper also provides recommendations for further improvement in established technologies for vinasse treatment.

The replacement of common acrylic derivatives by biodegradable materials in the formulation of superabsorbent materials would lessen the associated environmental impact. Moreover, the use of by-products or biowastes from the food industry that are usually discarded would promote a desired circular economy. The present study deals with the development of superabsorbent materials based on a by-product from the meat industry, namely plasma protein, focusing on the effects of a freeze-drying stage before blending with glycerol and eventual injection molding. More specifically, this freeze-drying stage is carried out either directly on the protein flour or after its solubilization in deionized water (10% w/w). Superabsorbent materials obtained after this solubilization-freeze-drying process display higher Young’s modulus and tensile strength values, without affecting their water uptake capacity. As greater water uptake is commonly related to poorer mechanical properties, the proposed solubilization-freeze-drying process is a useful strategy for producing strengthened hydrophilic materials.

Incineration is one of the options available to dispose municipal solid wastes (MSW) as it is capable of breaking down hazardous non-metallic wastes besides destroying bacteria and viruses. In terms of volume of wastes, incineration can reduce almost instantaneously by 90 %. In 1998, the government of Malaysia embarked on a pilot project to use incinerators to dispose MSW in four popular resort islands to see the effectiveness of this technique of waste disposal. Seven units of mini incinerators were installed on the islands and the local municipals were made responsible to manage and maintain.This project looked into the problems arises when incineration is used for MSW disposal on these islands. Data collected revealed that the plants were not properly managed and maintained. This was due to the lack of funds available for effective and smooth operation and the absence of highly expert personnel required to maintain the plant. Other factors that contribute to the inefficiency are inadequate air pollution control facilities and the infrastructure which do not condon the foul odour. Further research work need to be done to monitor the operation of these incinerators in order to explore its potential to dispose waste safely, effectively and cleanly.

In the current conditions of import substitution, the effective use of secondary raw materials in the meat industry is a relevant issue. A significant source of animal proteins is by-products, the yield of which is about 10% of livestock weight. Some by-products, including beef rumen, contain collagen-containing tissues which require modification for tenderization and deodorization. In order to modify rumen tissues, the biotechnological method of treatment with an enzyme solution, lysate, obtained from a whole bovine abomasum was preferred to the known method where enzyme solution is prepared from an abomasal mucosa. The purpose of this project was to study the activity of lysate from a whole bovine abomasum for the modification of rumen tissue to use it in cooked sausage formulations. We have suggested the method of obtaining enzyme solution based on infusing the minced abomasum in a reaction mixture – water, chlorohydric acid, and sodium tripolyphosphate – followed by filtering. The dependence of proteolytic and collagenase activities of the solution obtained from phosphate dose introduced have been studied; it have been revealed that 1.5% of tripolyphosphate is the optimal dose for efficient extraction of enzymes from the whole abomasum. Besides, an effect of the enzyme solution on functional and technological properties of a heat-treated rumen has been studied, and the improvement of hydro- and lipophilic characteristics has been revealed. Paste with modified rumen has been developed and found that the maximum possible dose of rumen for use in cooked sausage from horsemeat is 15%. The color on the cut of sausage developed was identical to that of beef sausage. Thus, paste made on the basis of modified rumen contributes to the formation of functional and technological properties, the stabilization of the color characteristics of the final product, as well as the effective use of basic meat raw materials and the expansion of the range of economy class high-protein sausage production.
