Recycling of waste to material

FORCE Technology, DTU Risø and SUNBY have been working on old test blades at LM Wind Power to provide test materials for various work packages for the GenVind project -- a EUR 5.8 million initiative focused on developing sustainable disposal options for composite materials.

Avoiding landfills 

By 2020, the Environmental Protection Agency expects about 20 Ktons of composite materials to be quietly waiting for break down in Denmark's landfill deposits. As of today, no concrete solution to recycle or recover this high-value material has been in place. Therefore, as industries using composite materials are experiencing serious growth (marine, aircraft and wind sectors), this type of material accumulates in landifll deposits at an increasing pace. This includes production but also end-of-life waste.

SUNBY aims at developing efficient ways to reuse these high-value materials directly. A sigificant share of the available composite material waste is present in wind turbine blades.

19.1 m and 25 m blades have been dissected in 5 m length sections. The sections of the 25 m blade have been driven to Copenhagen, while the sections of the 19.1m blade have been transported to SUNBY for further testing.

These blades should provide test materials for the work packages related to processing methods in TP2 and TP3 as well as pyrolysis and solvolysis work in WPs.

The bright green island that will be the first zero waste region in Europe

30 January 2019
The circular economy marks a paradigm shift. Recognising that our current linear economic patterns, where we produce, consume and discard are unsustainable, a new economic model has been proposed. In a circular economy, the emphasis is on reducing, recycling, repairing and sharing. In essence, it means an end to waste. While still in its infancy, actors around the globe are engaged in reorienting their local societies towards a more sustainable, inclusive circular economy.
