What Recology does for you. video camera

Recology Grover Compost Field Recology Grover Environmental Products (RGEP), formally known as Grover Environmental Products, was acquired in March 2010 by Recology a leading recycling and resource recovery company.

RGEP operates two facilities. The first is a 23-acre site in Modesto, CA that produces a variety of decorative mulches from recycled wood, as well as recycled arbor and bark products. The second site is a 166-acre composting facility in Vernalis, CA that produces a premium quality compost produced primarily from yard trimmings as well as food scraps. As the final step in the green waste recycling process, the exceptional quality reflects the Recology Grover commitment to the best and highest use of all resources. Our product is used in agricultural, landscape, and turf management applications, and is recognized for its ability to increase organic content and add biological and microbial life to the soil.

Our compost products are manufactured to the highest standards of the U.S. Composting Council Seal of Testing Assurance program (STA), and the Organic Material Review Institute (OMRI), and are listed in the California Certified Organic Farmers (CCOF) handbook.
