Abstract: Nowadays Industrial waste management is the key concern over the world. Biogas generation and bio-compost from knitting, cutting, spinning waste is one of the right and sustainable way of waste management. Wastage is generated almost all process in spinning, knitting and cutting in the industry. Cotton contains huge amount of dust, foreign-matters, seed and other particles. Micro dust of cotton waste has no salability and pollutes the atmosphere. Mostly, it is disposed of by burning as a result increase the CO2 level in the atmosphere which is the threat for environment as pollutes the surrounding areas. The main objective of this project is sustainable use of cotton waste by producing biogas and utilization of Slurry after Biogas Generation. Biogas generation by anaerobic digestion is sustainable, cost effective and eco-friendly method in Bangladesh. Finally, our concern is to maximum utilization all collected cotton wastes in a sustainable way i.e. anaerobic digestion way. Our experiments on wastes where those wastes produced bio-gas such as spinning cotton micro dust: 1st of all for production of gas to observe; after 30-40 days of feeding 180cc biogas was generated from 100g cotton spinning dust via lab scale biogas plant & gas also confirmed via flammability test. On the other hand smaller size of cotton cutting jhut fabric show comparatively low gas production and found that gas production depend on decomposition rate of cotton waste. Slurry treatment applied in a plant after generation of biogas and output of this application showing that many new leafs were grown and looking more refresh within 12-14 days. So, unusable spinning cotton waste can be resources for our economy and environment instead of hazards or waste. We have recommended that yarn singeing machine can be run by produced biogas.
