The Liverpool Guild of Students, England

The University of Liverpool’s students’ union (SU) – the Green Guild of Students – has been working with our A700 Rocket Composter and Dehydra Food Waste Dewaterer, to help reduce food waste, boost the site’s recycling rates, and promote sustainability. The resulting compost is used in the on-site rooftop gardens and cultivation plots for students to grow vegetables for using in the canteen – a truly circular model!

Bybonden, Norway

Our A700 in-vessel Rocket Composter is in Bergen, helping urban farming and growing firm Bybonden, to set up the country’s first ever decentralised solution for food waste. Normally, Norway’s food waste is transported to gas plants or incinerators, but this new solution is helping to reduce the country’s carbon emissions while creating a valuable compost resource for cultivating fresh produce.
