Page 16 - U4SSC Case study: Reducing food waste, June 2020

Nearly all waste collection trucks, and more than 150 buses in Oslo, now run on biogas produced from
food waste and wastewater, which help to reduce the city’s overall CO emissions. The liquid fertilizers

used by local farmers also reduce the demand for phosphorus-based fertilizers. This is beneficial
because producing synthetic fertilizers involves mining limited resources such as phosphate rock.

Compost and soil qualities from composting garden waste are highly demanded from citizens and from
professional gardeners, thus reducing the use of other resources of soil and compost based on peat.
