“As pet ownership increases, and trends continue in pet food toward higher content and quality of meat, globally, pet ownership will compound the environmental impacts of human dietary choices.”

Research summary

At petgood we are committed to leave no pawprints behind; sustainability is one of our core philosophies. There is a growing global demand for consumable protein sources by both humans and animals. Insects represent a highly sustainable protein source, as they have a favourable feed conversion efficiency, and can be reared on organic side streams (i.e. organic plant and grain waste products). They produce 94% less greenhouse emissions, and utilize 93% less land, 92% less feed and 80% less water in comparison to beef. This makes our insect-based dog food a sustainable and healthy alternative for our companion animals.
