The UK cannot reach net-zero when anaerobic digestion (AD) is the most common use of organic waste. AD converts much of the carbon in food waste directly to CO2 and the rest to methane, which is burned to produce even more CO2. Using food to create CO2 intensive energy is inherently wasteful and AD is an outdated technology in need of replacement.
AgriGrub instead locks that carbon up into useful forms using the Black Soldier Fly larvae, a unique species of insect which can quickly consume a range of organic wastes. Fully grown grubs are dried and ground to produce a protein meal, eliminating the need for deforestation-heavy soy meal. The grubs’ manure is also dried and sold as a shelf stable, carbon -neutral, organic fertiliser which has potential as a biocontrol agent against treatment resistant pests and diseases.
