Abstract:

Though tannery industries such as RMG and pharmaceuticals have played a significant part in the country's economic sectors, they have had a serious detrimental impact on tannery workers and the Dhaka metropolitan environment. The major objective of the study was to measure the association between socio-demographic factors and perceptions of local people towards tannery industrial wastes. Following a simple random sampling technique, this study chose 384 respondents from the study area. The findings of the study reveal that a whopping 95% of respondents reported that tannery industrial wastes h

This pollution not only poses serious health risks to workers in the industry and local residents but also harms the aquatic and terrestrial ecosystems. This paper provides a literature review of the environmental pollution caused by the tannery industry in Hazaribagh and identifies several mitigation strategies

The release of unprecedented tannery effluents into the environment as industrial wastes is one of the major causes of environmental pollution. Tannery waste containing heavy metals are usually disposed in landfills and streams in Challawa industrial estate Kano. In the present study tannery effluent discharge soil (polluted landfill), undischarged soil (control) were collected from the surrounding areas of tannery industry. The soil and physicochemical properties were examined in-situ. A total of eleven fungi species were found in the soil. The most common fungal strains viz., Aspergillus nig

Abstract:

Waste may be defined as an unwanted material generated after the manufacturing process from industry, agriculture, or from house hold activity. Waste causes many nuisances in the environment. It produces many types of infection, for human and animal. The sludge from tannery effluent plants has problem of disposal. Dewatered sludge is disposed off by land filling. However, it is not an appropriate solution, due to the land limitation. The production of sludge in tannery effluent plant is about to increase every year. In addition, the constraint to treat sludge is very high in cost and time-cons

The variations in the phase diagram were explained on the basis of ionic radius of cations, Gibbs free energy of hydration (ΔGhydation) of cations, and effective excluded volume (EEV) of salts. The salting-out capability of the cations followed the sequence: Sodium citrate > Potassium citrat

Among various tannery solid wastes, leather shaving dust contributes a large portion. Its reuse is a burning issue for sustainable tannery solid waste management. There are several possible ways to reuse this waste product. For example, leather shaving dust can be converted into useful products such as leather boards, biofuel, and compost.

According to the assumptions of the developed technological concept, at the first stage, the crushed mixture of chromium tannery waste is decomposed in the process of thermal pressure hydrolysis using appropriate process conditions in an alka
