The largest food waste digester in Europe was recently commissioned in
the UK by Spanish-owned company Ros Roca. The digester will convert
120,000 tons of food waste annually to biogas and organic fertilizer.
While large-scale food waste digesters are becoming more common in
Europe (Ros Roca has built 25), they are only beginning to be developed
in the US. This article discusses some of the issues related to
large-scale anaerobic digestion in the US and how these are being
overcome. Although large-scale, centralized digesters may take a high
volume of food waste in one facility, small-scale, local digesters
cannot be discounted. Both solutions offer an opportunity to solving
our food waste, energy, and nutrient dilemmas.
