Why Biogas? Why Now?

Biogas is a renewable energy that can be used as a substitute for natural gas or converted to clean electricity. Turning organic waste into biogas products creates a new revenue stream for farmers, reduces the amount of waste going into our landfills and waterways and removes harmful carbon emissions from our air.
