Biosolids Management

Our philosophy to biosolids management is simple – complete the cycle. We recover the valuable resources contained in this “waste” and return them to the earth where they belong.

Walker Environmental is an innovator in biosolids management. Our award winning facilities use the patented N-Viro® process to produce agricultural fertilizers and soil amendments, known as N-Rich®. Nutrient-rich and pasteurized, N-Rich® products are registered with the Canadian Food Inspection Agency under the Fertilizer Act. They also meet the standards set out in US EPA Regulation 40 CFR 503.

Walker Environmental can find short-term relief and long-term solutions to biosolids management challenges. We offer a variety of design, build, own and operate services that can develop a facility that suits your needs.
