Characterization of Leather Industry Wastes
In this research samples from solid wastes coming out from various process steps during manufacturing of garment sheep skins, shoe upper goat skins, shoe upper hides and sole leathers have been collected. These samples have been classified among themselves and their characteristics have been determined by various chemical analysis. By characterization of solid wastes which state problems for th...
متن کاملSolid wastes generation in the leather industry and its utilization for cleaner environmentA review
Leather industry, one of the polluting industries because of generation of huge amount of liquid and solid wastes, also emits obnoxious smell because of degradation of proteinous material of skin and generation of gases such as NH3, H2S and CO2. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing dusts and keratin wastes. Accumulation of these wastes lead to sludge problem and c...

متن کاملApplication of the Triangular Model in quantifying landfill gas emission from municipal solid wastes
Municipal solid waste landfills are significant parts of anthropogenic greenhouse gas emissions. The emission of significant amount of landfill gas has generated considerable interest in quantifying such emissions. The chemical composition of the organic constituents and potential amount of landfill gas that can be derived from the waste were determined. The chemical formulae for the rapidly bi...
