Researchers have initiated efforts to devise an eco-friendly and easy to maintain effluent treating system for silk dyeing, based on solar energy that meet the needs of the dyeing industry. Dye effluents are treated in a parabolic shaped trough, through solar thermal energy in the Solar Effluent Treatment System (SETS). The treated water is colorless, odorless, and matches all other quality parameters below the norms prescribed by Pollution Control Boards. The trials have showed that the treated water can be re-used for industrial and farming activities. The associated challenges of the process, such as the use of cleaning agents and workforce are eliminated, as the entire effluent treatment process employs the solar radiation alone. The equipment's design also allows treated water to collect separately, leaving the sludge inside the SETS itself, making it easy to dispose the dried sludge with due care. Source

Briquette is emerging as an alternative fuel for boilers in silk industry. The process of 'briquetting' is the physical transformation of the loose raw material, saw dust into a compact unit which gives much higher specific density of the material, which in turn, increases its combustion efficiency as compared to the loose material. Briquette is a compressed mass of saw dust with other flammable materials and fillers, often in regular shape of a pillow, brick or bar in hexagonal, square or spherical shape. The physical transformation of the loose raw material into a compact unit makes a briquette. Combustion is more uniform when compared to coal and boiler as response to changes in steam. It is high time that the silk industry avoids using the conventional fuels like firewood, coal, oils to meet its various demands. Source
