Biosolids Composting

Sustainable Generation has helped wastewater treatment plant operators, municipalities, and policymakers with everything needed to get started in biosolids composting. SG has assisted them throughout the design, construction, operation, meeting compliance, and beyond. Our goal is to make what is right for the environment right for business too.

What Our Customers Are Saying...

"With disposal and transportation costs increasing with no end in sight, plus an abundance of yard debris from our community, we decided to try biosolids composting at our Wastewater Treatment Plant to reduce our costs and create a Class A product. We went with the SG Mobile® System with GORE® Covers. The ease of operation and the cost savings made this a natural fit. The final product has been a huge hit with the locals who can’t get enough of the Class A compost. We recently doubled the size of our composting operation to keep up with our increasing volumes and demand. This system is easily scalable to meet future demands."

Mike Miller, Public Works Director, City of Florence, Oregon
