The redirection of former foods towards the biogas sector, for use as a waste stream, poses a significant challenge given the competing need for enhanced UK food security, says UKFFPA.
Waitrose has started trials diverting surplus food to the animal feed sector; It says the exercise should prevent 70% of food going to waste. Leading UK retailer, Tesco, is researching the use of surplus food as feedstock for insect rearing.
Leading fish feed producer, Skretting, said it is actively working with several retailers to ensure the fish that reaches the market meets their sustainability criteria.
