STAMFORD BIO-GAS - WASTE TO ENERGY PROJECT, STAMFORD, CT

Carlin Contracting is the construction arm of a design and development team working with the Stamford Water Pollution Control Authority (SWPCA) on a Department of Energy Research Project. Wastewater residuals (sludge, biosolids) are produced in every wastewater treatment plant as part of the water purification process. At the SWPCA, sludge is dried to create a Class A biosolid. The dried sludge is pelletized and currently used as fertilizer. The SWPCA is taking the management of biosolids a step further and undergoing a research project to create energy. The goal of the bio-gas research project is to convert the sludge biomass into a renewable fuel gas to power gas turbines and internal combustion engines (ICE), which in turn generate electricity. Waste heat capture for steam generation as well as hot water production is also being explored. With further research on creating bio-gas, we have the potential to:

• Reduce our dependence on foreign oil
• Reduce the cost for energy and demand on current oil supply
• Secure energy generator system (protection from terrorism)
• Solve a waste management problem
