Abstract:
Tanneries generate large amounts of solid and liquid wastes, which contain harmful chemical compounds in the environment, such as chromium, that is used in the tanning process. Until now, they have been almost completely dumped in landfills. Thus, finding eco-sustainable and innovative alternatives for the management and disposal of these wastes is becoming a huge challenge for tanneries and researchers around the world. In particular, the scientific and industrial communities have started using wastes to produce new materials exploiting the characteristics of leather, which are strongly conne

Background. The demand for diesel fuel is constantly increasing, requiring its alternate that could be sustainable, technically feasible, price competitive, and ecologically acceptable. Biodiesel is one of ecologically acceptable substitute for the conventional fuels. Methods. Sufficient lime fleshing waste was collected from Addis Ababa tannery share company. The limed fleshing waste in the wet condition was delimed using boric acid, dried, chopped, and subjected to Soxhlet extraction using petroleum ether solvent. The oil was treated by orthophosphoric acid and distilled water to remove gums

Abstract:
Pakistan, an agricultural country, raises 146.5 million commercial and domestic poultry birds, which generate around 544,831 tons of waste per year. This waste finds its final disposal in agricultural land as soil fertilizer or disposal site amendment. The usage of poultry litter for this purpose is uncontrolled, which results in environmental degradation such as emission of greenhouse gases, e.g., methane. However, alternative options such as thermochemical conversion of poultry litter can offer better solutions where this waste can be used as a low-cost carbon source for the synthesis of Mul

The commercial extract is available in an easily dissolvable spray dried form and in deference to its genus name Mimosaceae is referred to in the trade as Mimosa(3). Mimosa extract consists primarily of high molecular weight polymeric flavonoid units which also constitutes the active tanning ingredient.

Abstract:
The considerable volume of chromium-bearing wastes generated during the process of leather tanning, exacerbated by the potential for trivalent chromium in the wastes to be oxidised to the toxic hexavalent state, has created a major waste disposal dilemma for the tanning industry. While methods are available for the safe and effective treatment of residual chrome-tanning liquors, little has been done to address the issue of the chrome-bearing solid wastes. Given the increasingly stringent environmental compliance standards facing tanneries, unless an appropriate treatment process is developed i

Worldwide chromium waste from tanneries is a major environmental concern. A considerable amount of effort is being implemented by tanneries to resolve the environmental concerns. Because of the wide range of chemicals used in tanning, waste treatment is an important issue in the industry. All the tanneries put considerable money and effort into treating their effluent. South African tanneries currently have various methods of disposing of their chrome waste. Most have systems for recycling the waste and disposing of it in municipal waste dumps or it is dumped on the company's own land. Hence t

The problems of waste disposal in the tanning industry are unique in that the effluents are highly saline, have a high organic loading and contain heavy metals. Methods are available for the safe treatment and disposal of the latter two components, but the saline component requires the expensive outlay of evaporation ponds. This study has identified a possible use for the saline effluents, turning a problematic waste product into a potentially valuable by-product.

The objective of the research was to ascertain whether, when compared to a system'of standards, the theoretical promise that economic incentives offered as a low cost solution to the abatement problem, would hold in practice. This was done by applying environmental economic theory to the practical problem of controlling the effluent generated by firms in the South African leather industry. It was found that in this instance the theory did indeed hold in practice. Furthermore, it was found that of the incentives discussed by the theory, marketable permits were the most economically efficient. I

Abstract:
This chapter describes how environmental pollution is the major problem associated with rapid industrialization, due to which the quantity of solid waste generated from the industries is increasing substantially. Solid wastes generated in leather industries are briefly classified into pre-tanned and post-tanned wastes. Although landfills, composting, anaerobic digestion and thermal incineration are available for disposal of these solid wastes, they do again pose severe environmental and financial burdens to the tanners. Microbe-mediated tannery solid waste management points to the recovery of value-added products from these wastes. Microbial valorization of tannery solid wastes for the production of saleable products would be a convincing, challenging and eco-friendly opening for its utilization when compared to that of chemical and thermal hydrolysis. Exploitation of traditional chemicals could be reduced and innovative products could be recovered, enabling sustainable solid waste management. This would ultimately alleviate the solid waste disposal problems and financial crisis faced by the tanners.
