Got Organic Waste?

At CleanWorld, we’re actively seeking opportunities to help large and small organic producers located in northern California get their organic waste to our commercial BioDigesters.

CleanWorld organic waste what we can take

At CleanWorld, our high-solids system can take up to 50% solids without any added water. Got food waste in bags with some cafeteria plates and plastics?                No problem.

Our high-solids anaerobic digesters give us the ability to take your food and other organic waste (packaged and source-separated) and convert it into either negative carbon renewable transportation fuel or renewable electricity.

Call Ethan Hanohano at 916-201-1705 for your personal waste assessment and to take a tour of our facility, or connect through our Contact Portal. You can also complete a preliminary waste assessment through our Waste Assessment Portal.

CleanWorld BioDigesters can accept a variety of organic waste streams as feedstock, and our preprocessing technology allows a higher tolerance for contaminants than other organic waste disposal options.

Food and Restaurant Waste


Our proprietary high-solids technology was pioneered by Dr. Ruihong Zhang at UC Davis, the agricultural and renewable technology research hub of California. We know food waste.

CleanWorld’s BioDigesters accept most types of food waste from household collection programs, restaurants, and other food service operations. This food waste may be raw, frozen, dehydrated, cooked, rotten, or just leftover.

And most types of packaging do not present a problem. CleanWorld’s de-packaging technology means you don’t need to remove spoiled food from its containers. We can accept entire pallets of packaged or canned foods and provide a Certificate of Destruction, if required.

* Fruits, vegetables, and nuts
* Meat, poultry, and seafood
* Coffee grounds, coffee filters, and teabags
* Grains (rice, pasta, bread)
* Bakery items
* Dairy products and eggshells
* Pet food
* Fats, oils, and greases
* Biodegradable plastics, such as dinnerware and packaging (PHA- and PHB-based plastics are acceptable; PLA-based material is not)

Food Processing Waste

CleanWorld can accept food processing waste that is packaged or unpackaged.

CleanWorld AD technology can “eat” organic ag wastes such as manure and animal bedding. Or cafeteria waste from commercial buildings such as is diverted from buildings like CalEPA.

CleanWorld’s BioDigesters can handle the following types of materials mixed into organic waste streams. These products are separated out during preprocessing and sent for recycling. CleanWorld does not have the ability to process high amounts of glass or styrofoam.

* Cardboard: solid, corrugated, and waxed (tetra pak)

* Plastics: Polyethylene terephthalate (PET), disposable containers (such as clamshells), and plastic bags

* Metal: steel and aluminum cans

At CalEPA, they are now  diverting their organics through a new pilot program!

CleanWorld solves major labor costs because we can de-package packaged spoiled foods. We solve “where to put our food waste stream” problems for small and large commercial food companies like Campbell’s Soup, HP Hood, Intel, Strawhat Pizza, and the Hyatt Hotel.
