CompoCycle – a new concept in recycling

CompoCycle – a new concept in recycling

It's official. The new concept for processing redundant fibreglass has now been launched. Christened CompoCycle, the concept marks the first important step in a voluntary European system for recycling composites industry waste.

Developed by two German companies, Zajons and Holcim (Deutschland) AG, CompoCycle uses a patented process to convert fibreglass waste into a raw material for cement manufacture. Fiberline is the first Danish company to join the recycling scheme, which will have significance for many industries using fibreglass.

The European composites industry also backs the scheme and describes cement manufacture as the most sustainable recycling solution for fibreglass. CompoCycle meets the objectives of the European Waste Directive by fully utilizing the material and its energy content.

Fiberline's Sustainability Manager Benedikte Jørgensen hopes other companies will follow Fiberline's example and join the recycling scheme:
"For Fiberline, membership of the scheme means that we are close to achieving our target of 'zero landfill'. We believe that cement production is a simple and sustainable way of utilizing the resources contained in redundant fibreglass. We are delighted that the European trade association backs the scheme and we hope that it will receive widespread support from the composites industry."

How Zajons recycles fibreglass
Fibreglass-reinforced plastic composite (FRP), commonly referred to as fibreglass, consists of glass fibres embedded in thermoset plastic. The manufacture of cement is dependent on large quantities of sand - and sand is the primary constituent of glass and fibreglass. The thermoset plastic can also be used as an energy source in cement production and thereby replace the use of fossil fuels.

1. Fiberline sends its fibreglass waste to Zajons.
2. At Zajons the fibreglass enters a giant grinder where its calorific value is
    adjusted by the addition of other types of recycling materials in a
    patented process.
3. The finished recycling mix is sent to Holcim.
4. Holcim feeds the mix to its production kilns in northern Germany which
    make the finished cement.

This means that recycling 1000 tonnes of redundant Fiberline profiles in cement production saves around 450 tonnes of coal, 200 tonnes of chalk, 200 tonnes of sand and 150 tonnes of aluminium oxide (ref.: Holcim, 2010). No dusts, ash or other by-products are formed in the process.
