TECHNICAL SPECIFICATION

Our services.

We provide comprehensive processing of plastic materials — from mechanical shredding and granulation to separation, homogenization and lab analysis with certified protocol. All under one roof.
Granulation

Granulation

We operate a granulation extrusion line for PP, PE and PS materials. We process films, thermoforming materials, stretch film, miralon and rubber. Output granulate is filled into big bags (BB).

Powder production

Powder production

We manufacture fine plastic powders, specialising in PET. Grain size is tuned precisely to customer requirements. Finished material is packed into big bags up to 1,000 kg.

Material shredding

Material shredding

Six knife mills handle soft plastics — films, stretch film and miralon. For technical materials such as PET, PP and PE we operate a dedicated heavy-duty knife mill designed for demanding inputs. The regrind grain size is tuned precisely to your required fraction.

Shredding

Shredding

Oversized and bulky inputs go through industrial pre-shredding before fine knife-mill processing. We break down large plastic waste — blocks, baled material and oversized rejects — into a size suitable for knife mills and downstream recycling steps.

Laboratory analysis

Laboratory analysis

Our in-house lab is equipped with a Dynisco capillary plastometer. We analyse MFR, MVR and density for PET, PP, PE, PS and ABS. Every analysis is accompanied by a certified protocol.

Homogenization

Homogenization

We prepare material precisely to customer formulation — according to the required MFI, colour, material ratio and grain size. The result is a homogeneous material ready for further processing.

Compound

Compound

We turn industrial plastic waste into colour compound for further processing. The resulting material meets customer requirements for colour and composition.

Metal separation

Metal separation

We remove ferrous and non-ferrous metals from regrind via magnetic and induction separation. The resulting material is ready for safe downstream processing.

Material drying

Material drying

We remove residual moisture from all processed fractions, ensuring process stability and consistent input quality for extrusion lines.

Compaction

Compaction

We process light fractions, films and thermoforming waste into a compact bulk form — reducing volume and easing transport and downstream processing.

Industrial waste buy-back

Industrial waste buy-back

We purchase technological plastic waste directly from production — sprues, non-conforming parts and rejects. We handle pickup and full documentation.

Own vehicle fleet

Own vehicle fleet

We operate our own vehicle fleet to transport material to customers across Europe. Fast lead times and flexibility according to order volume.

Container transport

Container transport

We operate container transport with our own containers for high-volume and long-term contracts. Tailored solutions for regular deliveries and collection routes.

Material certification

Material certification

Every delivery is accompanied by a certified quality protocol with MFR, MVR and density analysis — a record of compliance with the customer’s technical specification.
