At our facilities in Appenzell, Switzerland, we transform your post-industrial thermoplastic waste into high-quality recycled granular.

Applying decades of expertise and the latest recycling technology for sorting, processing, and quality control, we are able to ensure the utmost quality of our recyclate and contribute to the continuous availability of viable recycled granular.

A commercially attractive alternative to virgin plastics, these reprocessed raw materials are put to use in a variety of ways – including in the creation of semi-finished engineering plastic products and shapes with recycled contents.

  • ISO 9001 certified recycling processes
  • Focus on recycling high-performance engineering plastics
  • Global leader in reprocessing PEEK, fluoroplastics, and polyamides
  • Custom compounding and toll manufacturing with recycled raw materials
  • Realizing KAITEKI - the sustainable wellbeing of people, society, and our planet

Our recycling technologies & services How we guarantee quality recyclate
Professional & customer-centric Recycling

To allow you to concentrate on your core competencies, we take care of professional recycling and all the necessary tasks for you: 

  • Disposal including proof of disposal 
  • Materials purchase (see AEB) 
  • Provision of containers and exchange containers; Bale press system on request
  • Compounding, granulation and material processing according to customer requirements
  • Retrieval of sublots 
  • Creation of disposal and recycling concepts for your plastic production waste
Grinding, dedusting & demetallizing Grinding

We take on all standard thermoplastics (for example production scrap, sprues, chunks, large volume molded parts, powders, foils, profiles, filaments) and grind them, including dedusting and demetallization. Select the desired grinding range between 6 mm and 10 mm yourself and you will receive the regrind back on time and packed in octabins or big bags for your production.

Thermoplastic regranulation Regranulating

We take over the regranulation of all common thermoplastics, for example from production scrap, sprues or molded parts as well as from ground material. We can even handle materials that are difficult to compound, such as foils or plastics containing fibers. If necessary, the material is homogenized to achieve uniform processing parameters. On request, we can also compound various additives as part of the regranulation according to your production requirements.

performance additives and coloring Compounding

We dye granules for you according to any color sample (for example RAL, Pantone, HKS). Because we do so in small batch sizes, your partnership with us can make an important contribution to sustainability, while also simplifying your process and generating economic incentives. We also have competencies in handling additives with special pigments and improving technical properties.

Ensuring purity in recyclate Sorting and cleaning

Purity is essential to creating economically viable recycled engineering plastics. With a sophisticated system of inspection, analysis, and sorting equipment, we ensure the highest level of material purity in our recyclate. We were one of the first companies worldwide to use X-ray technology to inspect our recycled materials.

We grind for you Toll manufacturing

Do you want to regranulate your thermoplastic waste material, but do not have any free capacity at your facilities? Does outsourcing regranulation make sense for economic reasons? Then our toll manufacturing service is the perfect recycling concept for you. 

As a customer, you will benefit from our extensive experience as well as from our professional production area and quality management. We are ISO 9001: 2015 certified and, thanks to the most modern analysis technology, we are able to carry out a 100% inspection of the plastic regranulate.
