What does KRM do?
KRM Kunststoff-Recycling-Maschinen GmbH in Kühnsdorf, Carinthia, Austria, produces high-quality plastic regranulates and regrind from post-consumer and production waste. It also offers toll processing, compounding, plastics trading and the purchase and sale of recycling machines.
Which plastics does KRM process?
KRM mainly processes polyolefins and styrene polymers: PP, LDPE, HDPE, PP/PE blends, PPC, PPH and polystyrene (PS). In trading, KRM covers all thermoplastics, including engineering plastics.
Does KRM buy plastic waste?
Yes. KRM buys plastics from production and post-consumer collection as bales, rolls, regrind or granulate and organises the collection.
Can I get my own production scrap back?
Yes, through toll processing. KRM processes your scrap into regrind or regranulate and returns it as raw material for your production.
Which certifications does KRM hold?
KRM is certified to ISO 9001 and ISO 14001 (Quality Austria, IQNet) and holds an ISCC PLUS certification, a RecyClass Recycling Process Certificate and evidence of CO₂ reduction.
Where is KRM located?
KRM is based at Mitte 68, 9125 Kühnsdorf, in the Völkermarkt district of Carinthia, Austria. Phone +43 4232 52020-0, email office@krm-recycling.com.
Recycling process
More questions? +43 4232 52020-0
How does plastic recycling work?
At KRM, plastics collected by type are broken down in a shredder and processed into regrind in granulators. Currently three extrusion lines melt the regrind and form it into regranulate, which is used again as a raw material in production.
What is mechanical recycling?
In mechanical recycling, the molecular structure of the plastic is preserved. It is only ground and remelted. KRM uses this method.
Why is sorting by type so important?
Only plastic collected by type produces a recyclate with reliable properties. That is why KRM advises, right where the waste arises, on how to collect production waste separately.
What is made from regranulate?
Regranulate is used to make, for example, packaging, furniture, pipes, containers, car parts and textiles.

Which plastics does KRM buy?
KRM buys single-variety plastics from production and post-consumer collection, mainly PP, LDPE, HDPE, PP/PE, PPC, PPH and PS, as bales, rolls, regrind or granulate. For trading, KRM also takes other thermoplastics.
Why does the material have to be single-variety and clean?
KRM uses single-variety, clean plastics. There is no sorting or washing in production. Only single-variety material produces a recyclate with reliable properties.
Does KRM help with collecting by type?
Yes. KRM offers support right where the waste arises, ensures orderly collection at the production site and develops waste management concepts aimed at collecting as many materials as possible by type.
How is the material collected?
Collections of raw material follow a precise schedule. For smooth logistics, KRM works closely with selected hauliers.
Can I get my material back after processing?
Yes, through toll processing. KRM processes your scrap into regrind or granulate and returns it as raw material.
Plastics and regranulate
More questions? +43 4232 52020-0
In what form does KRM supply recycled plastics?
KRM supplies regrind and regranulate. Using mixing and dosing units on the extruders, blends and filled plastics to customer specification are also possible.
Are there data sheets for the regranulates?
Yes. Technical data sheets are available for download: PO grey, LDPE white, HDPE black, PPC black, PPH natural, PPH white and PSH black. Other grades on request.
Does KRM also trade in virgin material?
Yes. KRM trades virgin and off-grade qualities of all thermoplastics, including engineering plastics.
Regrind and regranulates
More questions? +43 4232 52020-0
What is the difference between regrind and regranulate?
Regrind is ground plastic in flake form. Regranulate is produced when regrind is melted, filtered and extruded into uniform pellets. Regranulate can be dosed and processed like virgin material.
Can KRM produce regranulate to a custom formulation?
Yes. Using mixing and dosing units on the extruders, KRM produces blends and filled plastics to the customer’s specifications.
Toll processing
More questions? +43 4232 52020-0
What does toll processing mean?
In toll processing, KRM processes a customer’s plastic waste on their behalf. The material remains the customer’s property and is returned as regrind or regranulate.
What requirements does the material have to meet?
The material should be collected as single-variety as possible. KRM advises on collection at the production site and tests samples in its in-house laboratory.
Post-consumer recycling
More questions? +43 4232 52020-0
What is post-consumer plastic?
Post-consumer plastic comes from products that have already been used by consumers, such as packaging. Post-industrial plastic, by contrast, arises directly in production.
Is KRM’s post-consumer recyclate certified?
KRM holds a RecyClass Recycling Process Certificate and an ISCC PLUS certification for the traceability of recycled raw materials.
Compounding
More questions? +43 4232 52020-0
What is compounding?
Compounding is the processing of a plastic by adding substances such as fillers, additives or other polymers in order to achieve the desired properties.
Plastics trading

Does KRM buy plastic waste?
Yes. KRM buys plastics from post-consumer and post-industrial sources as bales, rolls, regrind or granulate and organises the logistics.
What does off-grade mean?
Off-grade is virgin material that narrowly misses a specification, for example in colour or melt flow index. It is fully usable for many applications and cheaper than prime material.

How does KRM help make waste recyclable?
KRM supports plastics processors in optimising their processes. The necessary material analyses are carried out in the in-house laboratory. The aim is to obtain the maximum amount of single-variety material.
Sustainability
More questions? +43 4232 52020-0
Where does KRM get its electricity from?
KRM sources energy exclusively from sustainable generation: electricity from 100% hydropower, combined with a photovoltaic system.
Is KRM climate-neutral?
Climate neutrality is the stated goal. To achieve it, KRM relies on green electricity, photovoltaics and a vehicle fleet that is gradually being switched to electric cars. The CO₂ reduction is documented in a separate certificate.
Why recyclate instead of virgin material?
Recyclate reduces the need for new plastic, conserves resources and lowers the environmental impact. Companies that use recyclate can also save costs.
