Maggot waste digestion food production. Close-up of numerous maggots of the housefly (Musca domestica) being used in waste digestion and food production research. The maggots (larvae) are being used to digest the residual material from anaerobic digesters used to break down organic waste. The product is the maggots themselves, which are harvested before they turn into flies. The maggots, processed for the oils and protein they contain, are used to produce animal feed. This research was carried out in 2012 by the UK's Food and Environment Research Agency (FERA).
