Technology and Process

River Road Research has developed a suite of technologies that allows the complete disposal of food waste in an economically and ecologically positive way. Our process for the recycling of food waste creates a sustainable protein source for use in animal and aquaculture feed providing significant environmental benefits compared to landfilling, composting, or anaerobic digestion. Our Black Soldier Fly Larvae (BSFL) convert underutilized nutrients from food waste into a sustainable source of protein, reducing the unsustainable use of grains, soybeans, fish, and vegetable oils currently used to feed animals and fish.

This bioconversion creates a virtuous circle that makes insect protein a sustainable and efficient alternative to fishmeal. We have experience in the following technology applications:

Food Waste Stabilization & Production of Insect Food
Black Soldier Fly Rearing
Production of Liquid, Inorganic Fertilizer from Food Waste
Microalgae Production
Pyomelanin Production from Food Waste
Chitin Production

Owareco Feed Trials with Black Soldier Fly Larvae

River Road Research received dry feed waste materials, from Owareco , to be tested for nutritional quality for growing larvae of the Black Soldier Fly. The following six sample types were received for experimentation.

Cafeteria Waste
Hospital Waste
Restaurant Waste
Grocery Store Waste
Food Bank Waste
Grocery Store Waste

The analysis of each sample showed a good food conversion ratio for each Owareco sample. The best results were from the food waste sourced from the hospital, restaurant, and the food bank. The results indicate that material produced by the Owareco process can be used to produce BSF larvae at a ratio of approximately 1 lb of larvae for each 1.8 lb of Owareco dry feed mixture.
