Lower-resource material testing
Laboratory extruders make it possible to test recycled and bio-based materials, as well as new formulations of standard polymers, using small batches before moving to a full production line.
Sustainability at Green Extrusion Technology
Practical sustainability with machines built to last
We help customers test new materials with less energy and material, return production waste to the process, and keep equipment working reliably for many years.

Our approach
Practical sustainability, not a slogan
For us, sustainability is connected to how a machine is used, how long it remains in service, and how much material and energy it helps the customer avoid wasting.
Production waste back into use
Granulators, shredders and Green REC repelletizing systems support closed-loop handling of clean in-house plastic waste.
Long working life
Solid frames, durable recyclable metals, replaceable wear parts and service-friendly construction help keep equipment productive for longer.
Built solid
Durability is part of sustainability
A machine that remains stable, repairable and productive for many years avoids premature replacement and makes better use of the materials and energy already invested in it.
✓
Robust mechanical construction
Solid frames and carefully selected machine components support stable operation and a long service life.

✓
Durable and recyclable materials
Steel, aluminium and other metals are selected for strength, repairability and high recycling potential at end of life.

Service-friendly design
Wear parts and standard industrial components can be maintained or replaced instead of replacing the complete machine.

European supply chain
We prefer reliable suppliers in Denmark and Europe where practical, helping us maintain quality, documentation and access to spare parts.

Circular use of materials
From material development to in-house recycling
Our product programme supports several practical steps in a more circular plastics process.
Test recycled and alternative materials
LabEx systems help R&D teams investigate recycled polymers, bio-based materials, compostable compounds, additives and multilayer structures before production scale.
Reduce waste to a reusable size
Granulators and single-shaft shredders prepare clean production scrap, start-up waste and rejected parts for controlled in-house reuse.
Bring clean waste back into production
Green REC repelletizing systems convert suitable in-house waste into consistent granules that can be evaluated and returned to the process.
Electrical and automation components
Working with a recognised sustainability leader
For key electrical and automation components, Green Extrusion Technology works in partnership with Schneider Electric and uses Schneider Electric products. Schneider Electric is one of the world’s leading energy technology and electrical equipment companies, with operations in more than 100 countries.
Schneider Electric was ranked first in Corporate Knights’ Global 100 in 2021 and 2025, becoming the first company to lead the ranking twice. Its Environmental Data Program builds on Green Premium and publishes lifecycle information such as carbon footprint, recycled material content, energy efficiency and end-of-life options for a broad product portfolio.
This supports our preference for widely supported components with clear documentation, long-term availability and transparent environmental information.
Smaller-scale testing
A laboratory trial can use far fewer resources
A full production extruder is designed to make saleable film. A laboratory extruder is designed for repeated small tests, recipe changes and controlled material development.
Illustrative polymer use per trial
870 kg→17 kg
Production trial compared with a LabEx trial, including the example purge and cleaning quantities.
Illustrative energy use per trial
1.215 kWh→55 kWh
Example warm-up, cleaning and test-production energy from the supplied calculation model.
These figures are an example based on adjustable assumptions. Actual material use, energy use, savings and payback depend on the production line, material, test duration, cleaning method, labour and lost production time.
Compare your present production trial with a LabEx test
Share your typical material use, energy cost, labour and production downtime. We can prepare a simple trial-cost comparison using your own figures.
