All household waste in Malmö is collected and 98 percent of the waste is reused or recycled into new material or energy. Energy production from waste are primarily biogas or incinerated in the waste-to-energy facility.
Organic and food waste
In Malmö it is mandatory to sort food waste for all households. From 2014 all citizens in Malmö are recycling their food waste through waste grinders, vacuum systems or paper bags in garbage bins. The food waste is collected to produce biogas which is used to fuel the city buses, garbage trucks, taxis and cars.
Malmö´s entire bus fleet is engineered to run on gaseous energy sources. Approximately 200 city buses run on a mix of biogas and CNG. As the production of biogas increases, an even larger percent of Malmö city buses will run on biogas which reduces greenhouse gas emissions, NOx emissions and particles.
A city built on district heating
District heating in Malmö is already well-incorporated, initiated in the city in 1959, and today it is one of Sweden´s largest district heating networks. Simultaneously, much of Malmö´s heat energy is provided by so-called ‘waste´ sources. Approximately 60 percent of Malmö´s heat energy is produced by the city incinerator via waste-to-energy and 16 percent of the district heating is provided by excess heat release from major industrial activities in the city.
Recycling in Malmö
Waste separation and recycling are commonly practiced amongst Malmö residents, as part of modern urban lifestyle behaviours. To help facilitate this behavioural trend, the municipal housing company, MKB, has constructed weather-proof complexes, each ”miljöhus” has separate containers clearly labelled, often with visual images, to recycle food waste, glass, newspaper and paper, cardboard, metal, plastic and batteries, as well as to accommodate the remaining waste.
