Around the world, pollution of the air and water from municipal, industrial and agricultural operations continues to grow. Governments and industries are constantly on the lookout for technologies that will allow for more efficient and cost-effective waste treatment. One technology that can successfully treat the organic fraction of wastes is anaerobic digestion (AD). When used in a fully-engineered system, AD not only provides pollution prevention, but also allows for sustainable energy, compost and nutrient recovery. Thus, AD can convert a disposal problem into a profit center. As the technology continues to mature, AD is becoming a key method for both waste reduction and recovery of a renewable fuel and other valuable co-products.
This web site provides an outline of the status of AD as the most promising method of treating the organic fraction of animal manure, municipal solid waste (MSW), and other wastes. It also summarizes policy issues which influence the deployment of AD technology, facility design concepts, the energy, economic and environmental issues relating to AD, and the comparison of alternative treatment processes.
