The Glass Cluster in Naestved

A great example of circular economy

Ressource City’s Glass Cluster is one of our best-practice examples of circular economy. In line with our vision, Ressource City’s office is in a former warehouse in an old industrial area. In the same industrial area, Reiling Glasrecycling Denmark is located, who, along with Ardagh Glass Holmegaard form Resource City’s Glass Cluster.

The Glass Cluster collects and sorts approximately 125.000 tons of glass per year. The glass are then recycled into roughly 800 million bottles and jars every year, thereby reducing the need for virgin materials. By doing so they are also reducing more or less 18.000 tons of CO2 anually.

Not only does the Glass Cluster produce new products from used materials, it also distribute surplus heat from the production to the local district heating grid. By doing this they contribute with approximately >90% of the district heating in the town Fensmark in Naestved Municipality

In addition, a biogas plant is being installed to supply the Glass Cluster with biogas to reduce greenhouse gas emissions from the current use of natural gas. One of the newest innovations is to turn biproduct glass, that can not be recycled into new bottles and jars, into insulation. Initiatives like this makes the Glass Cluster innovative and always prepared to seize sustainable growth potentials.

The experience gained from the Glass Cluster is part of the method that Ressource City replicates to support new circular collaborations. Since its launch in 2015 Ressource City has initiated and facilitated several projects and new collaborations based on circular economy and sustainable waste management.

The consumers buy and uses bottles and jars made of glass. After use glass products get discarded in the recycling bin and collected from all Danish municipalities.

Reiling Glasrecycling sorts the glass and bring it to the glass manufacturer Ardagh Glass in Holmegaard, Naestved. The shards then get melted into new glass products. The surplus heat from the production heats up >90% of the housing in Fensmark, Naestved.
