Spent coffee grounds hold valuable potential and can be used – after the government’s approval in terms of waste vs by-product – in animal nutrition. They can serve as direct feed for livestock or be repurposed as nourishment for larvae, which undergo rapid growth and metamorphose into protein-rich “bars” suitable for animal consumption. Remarkably, adopting the former utilization has shown promising environmental benefits, notably reducing enteric methane emissions by up to 20% in dairy sheep¹. This innovative approach not only maximizes resource efficiency but also contributes to sustainable agricultural practices.
