Read about other ways to turn waste into renewable energy.

Manure digester projects produce biogas methane that can be used to create clean, renewable electricity and heat. In addition, these facilities can also help with water table contamination issues and provide benefits for agricultural operations. After the digestion process, the solids and liquids are commonly separated. An additional benefit and revenue stream can be created by composting the solids into a fiber byproduct that can be sold as a soil amendment for a number of landscaping and fertilizing applications. To achieve desired specifications for the compost customers requires turning windrows of the solid fiber on a regular basis until it is ready for sale. Microbes feeding on the material create heat within the mass. As the windrows are turned, heat is released and the material is aerated for optimal efficiency in the process.

The photo on the left shows a self-propelled compost turner. The photo on the right shows the turner moving through a windrow. Agricultural and livestock operations may be good sources of biomass that can be utilized in a productive manner to create clean electricity with local, renewable resources, and create unique partnerships with multiple economic and environmental benefits.
