Green Extrusion Technology builds laboratory extruders, compact MULTI-X extruders, and granulators, shredders and repelletizing lines for in house recycling. The machines are sized for laboratories, technical schools and production halls.
One program — laboratory to in house production
Mono layer, ABA and 3 layer blown film laboratory extruders for testing, teaching and product development. Screw diameters from 18 to 30 mm, die inserts from Ø25 to Ø70 mm, and film widths from 50 to 300 mm. Multilayer structures up to 8 layers are available as project specific configurations.
See laboratory extruders
Multi-X all around extruders from 18 to 30 mm for pipes, 3D printing filament and technical profiles. They run standalone, or as a coextruder feeding a second material into an existing line. Tabletop, pillar mounted or floor level, depending on where the machine has to stand.
See compact extruders
An independent take off and winding unit supplied without extruders. Connect it to a LabEx laboratory extruder, a Multi-X all around extruder, or an extruder you already own, and start producing and testing blown film without replacing the machine you have.

Compact repelletizing lines that turn clean production scrap back into reusable pellets. Feeding, filtration, degassing and pelletizing in one line, sized for in house recovery rather than for a recycling plant. The material stays in your own process.
See repelletizing
Durable, compact granulators up to 30 kW for in house size reduction of plastics and bio based polymers. Rotor design, knife geometry and screen size are chosen for the material and the regrind quality you need, not sold as one size for everything.
See granulators
Single shaft shredders, easy to operate and with minimal maintenance, for efficient in house size reduction. Built for the bulky material a granulator cannot take directly: purge lumps, thick walled parts, rolls and rejected production.
See shredders
Extrusion components, feeding and handling equipment, granulator and shredder wear parts, cleaning products and consumables for laboratory and production machines. Screws, barrels, die heads, screen changers, air rings, winders and hopper loaders.

Trial new polymers, recycled grades, bioplastics, masterbatch and film structures on a small scale, without stopping a production line.
Laboratory extruders →
Pipes, 3D printing filament, technical profiles and film samples, from a compact extruder that fits in a laboratory or a workshop.
Compact extruders →
Cut film, sheets, purge lumps and rejected parts down to a size you can handle, store and reuse, instead of paying to have it taken away.
Granulators and shredders →
Bring clean production scrap back into your own process as reusable granulate, rather than selling it away and buying new material.
Repelletizing →Manufactured in Denmark with reliable European components, the machines from Green Extrusion Technology are built using durable, recyclable materials to support long term sustainability.
Explore our Know How articles for practical information about extrusion, polymers, recycling, granulation and material testing. They can help you understand the process, compare possibilities and identify the equipment that best fits your application.
Why testing a new material on a production line is usually the most expensive way to get an answer, and what a laboratory line tells you first.
