About Us

We Help Companies Achieve a Sustainable and Economical Future

For over 30 years, we’ve been reducing costs and increasing sustainability for food and beverage producers, industrial manufacturing companies, water and waste utilities, and municipalities through turn-key, beneficial-use waste management solutions. Our solutions help companies attain their zero-landfill goals while reducing waste management costs. 

We strive to find innovative ways to reuse and recycle food processing solid and liquid waste in ways that benefit the environment, meet regulations, and reduce operational costs. We redirect waste from landfills to earth-friendly, beneficial uses: organic land application, composting, manufactured soil, anaerobic digestion, animal feed, fertilizer, energy/fuel production, and alternative raw materials for consumer goods (such as fireplace logs, fuel and grilling pellets, fire starters and potting soil).

Our expertise includes beneficial residuals management of non-hazardous organic materials. We conduct waste audits, design and implement custom solutions, and provide turnkey management of those solutions.
