“…It is guesstimated that about one third of this or 100 million tons of residues are not being utilized and are disposed of by burning them in the open fields (NPCMR, 2014). Unsustainable management practices of biomass waste would create high adverse environmental impacts (Ross, 2018;ruhela et al, 2020;Bhardwaj et al, 2019). Energy can be harvested from a biomass, a significant renewable energy source forever.…”

Crops can also be grown for energy could be produced in large quantities, and likely to become the most popular in the future. One of the most widely used renewable energy source for heating is biomass in the form of fuel wood, charcoal, agriculture residues etc. A lab model of Fluidized Bed Gasifier (FBG) for handling low density and leafy biomass materials like rice husk, saw dust, bagasse, tree leaves etc. was developed. The performance study of the gasifier was determined by different parameters such as air factor, gas yield, calorific value and hot gas efficiency. The average gas yield of 2.5 m3/kg and a maximum possible feed rate 10 kg/h with the existing feeding system the capacity of the unit was worked out as 20kW.

“…Tropical and subtropical countries like India utilises the bacteria for decomposing the different types of waste. Currently in India, high proportion of distilleries has adopted activated sludge process in condensate polishing unit to treat the highly polluted condensates from the distillery units (Pandey et al, 2003;Sharma et al, 2007;Ayub et al, 2012;Patyal, 2015;Ruhela et al, 2020). Distilleries have installed condensate polishing units based on up-flow anaerobic sludge blanket (UASB) technology along with activated sludge process (Patyal, 2015;Ruhela et al, 2020).…”

These technologies are necessary for sustainable development and requires valorisation strategies to achieve zero liquid discharge (Mikucka and Zielińska, 2003).…”

Ethanol-distilleries are the key supporter to the world's economy, but these are moreover one of the major sources of environmental pollution that can impact the human heath if the effluents are not treated in proper manners. Distillery effluents with high biological oxygen demand (BOD) and chemical oxygen demand (COD) contains toxic chemicals which are reported to be of carcinogenic and mutagenic in nature. One of the widely used technology for the distillery wastewater treatment is based on up-flow anaerobic sludge blanket (UASB) technology along with activated sludge process. This technology has fulfilled a need for high efficiency treatment of wastes from various distilleries. With the increasing demands of distillery units and strict guidelines by government agencies for the environment protection, more efforts are required to achieve the zero liquid discharge (ZLD). The research reported in this paper is an effort to perform the in-situ study for evaluating the impact of varying retention times on the efficiency of the condensate Polishing Unit (CPU) based on UASB technology along with activated sludge process for ZLD. The primary objective was to determine pH, BOD and COD after increasing the HRTs in the aeration tank.
