| Abstract |
Distillery sludge generated from the alcohol production plants is considered as a nuisance. It is one of the main sources of environmental pollution because of the presence of high amount of sulphate, phenolic compounds (500.3 +/- 26.46 mg/kg), melanoidins, organic matter (14%) and heavy metals (like 18% Mn, 6% Ni and 4% Pb). Hence, advancement in the available techniques for managing this sludge is a prerequisite for its safe and sustainable disposal. The article delivers an assessment of the challenges involved in the treatment of distillery sludge, existing practices, disposal and possible routes for energy recovery. Considering the high nutritional and energy values of the distillery sludge, the associated limitations and challenges of the available sludge management options, it was aimed to highlight alternative methods of its treatment. The present review also compares the current distillery sludge management solutions concerning their environmental sustainability. The most widely used methods, including treatment and disposal techniques considering the current legislation in different countries, have also been dealt with. Furthermore, the study also deals with the resource recovery approaches in order to recover value-added products and available nutrients from distillery sludge. Resource and energy recovery options are therefore considered as sustainable solutions to fulfill the present and future energy requirement and visualize it as a potential opportunity instead of a nuisance.
