More than 1.2 million. ton of food is wasted in Denmark every year. This is not only economically unviable, but it also puts an excessive strain on ressource and the environment.
Since 2018, AffaldPlus has treated food waste in what can be best described as a gigantic food processor that converts food waste into pulp. The provider of the processor is the Danish company Gemidan Ecogi. The processor ensures that plastic bags, waste and other materiales are chopped into smaller pieces, whereby the food can be seperated from what is not organic. After treatment, the food waste is turned into a pulp, which is used in the production of biogas. After the production, the biogas residue is used as an organic fertilizer in the fields. In 2024 the plant was sold to a private company, Nordic Biowaste, but is still situated at AffaldPlus’ energy plant.
19,000 tons of foodwaste is annually converted into approximately 23,000 tons of pulp which – again – is transformed into biogas and fertilizer.
