MAS Tech can provide individual technologies and complete recycling line concepts. The right scope depends on whether the customer needs a machine upgrade, a process improvement or a fully integrated recycling solution.
A project should start with the material stream, contamination profile, required output quality and production goals. MAS can then assess which process stages, technologies and tests are needed.
Recycling Technologies
A twin-screw extruder uses two screws to melt, mix, homogenise and process plastic material. MAS twin-screw technology is used in recycling, compounding and re-compounding applications.
Melt filtration removes solid contaminants from molten plastic during extrusion. It helps improve melt cleanliness, process stability and recyclate quality.
The MAS CDF system is a continuous melt filtration technology for removing contamination from plastic melt. It can adapt filtration behaviour to material and contamination changes.
Material preparation conditions plastic before extrusion so it can be fed, melted and processed more reliably. It can include size, bulk density, moisture and contamination considerations.
Degassing removes volatile components, trapped gases and moisture-related vapours from the melt where the material requires it. This supports more stable extrusion and better recyclate quality.
The DRD Dry Cleaner is used for dry cleaning and drying plastic material where surface contamination or moisture needs to be addressed before extrusion.
Automation connects process control, monitoring and operation across a recycling line. It helps operators manage variable material streams and keep production conditions more consistent.
Upgrade lines combine recycling and process improvements to raise material value, often by adding compounding, filtration, degassing or other line stages.
Recycling Processes
Plastics recycling converts plastic waste, production scrap or regrind into reusable material. Industrial recycling can include preparation, cleaning, extrusion, degassing, melt filtration, pelletising and compounding.
Film recycling processes flexible plastic films into recycled material. The process often requires careful feeding, preparation, drying, extrusion and melt filtration because film can have low bulk density and variable contamination.
PET recycling converts PET material into reusable recyclate for suitable downstream applications. The process must consider material quality, drying, extrusion, filtration and final use requirements.
Rigid plastics recycling processes solid plastic items, regrind, moulded parts or industrial scrap into reusable material. It often requires preparation, contamination management, extrusion and melt filtration.
Plastic compounding mixes polymers with additives, fillers, colourants, stabilisers or reinforcements to create a material with defined properties.
Re-compounding upgrades recycled plastics by combining recycling with additive dosing, homogenisation, degassing, filtration and pelletising. It helps turn recycled feedstock into higher-value compounds.
A complete recycling line is an integrated process system that connects the equipment needed to convert plastic input material into reusable recyclate.
Complete recycling lines guide material through connected stages such as preparation, drying, extrusion, degassing, filtration and pelletising. The configuration depends on the material stream and target output quality.
Materials
MAS materials referenced across solution pages include PE, PP, PET, ABS, PS, PA, regrind, post-consumer plastics, post-industrial plastics and production scrap. Final suitability depends on the specific material and process target.
Yes. MAS technologies are used for polyolefin streams such as PE and PP in recycling, melt filtration, compounding and re-compounding applications, subject to material evaluation.
MAS supports PET recycling applications where the process concept is matched to the material quality, drying needs, extrusion requirements and target output.
Engineering plastics such as ABS, PS and PA can be assessed for re-compounding where the material stream, formulation and process requirements are technically suitable.
Regrind is plastic material that has been mechanically size-reduced, often from production scrap, rigid parts or other recyclable plastic items. It can be reprocessed when quality and contamination levels allow.
Post-consumer plastic comes from products after use, while post-industrial plastic usually comes from manufacturing or production processes. Post-consumer streams often require more contamination management.
Contamination can disturb feeding, extrusion, filtration, pellet quality and downstream manufacturing. Material preparation and melt filtration help manage contamination risks.
Engineering And Innovation
Yes. MAS configures recycling systems around the customer’s material, contamination profile, process requirements and output quality target.
Laboratory testing helps evaluate material behaviour before final process decisions are made. It can support choices around preparation, extrusion, filtration, degassing and compounding.
Yes. MAS recycling systems can be modular and upgradeable, allowing line concepts to evolve as material streams, production targets or quality requirements change.
MAS improves recyclate quality by combining material preparation, controlled extrusion, degassing, continuous melt filtration, compounding and automation in a process concept matched to the material.
MAS has innovation and patent-related content for selected technologies. Specific patent claims should be reviewed on the relevant technology pages and verified before use in project documentation.
MAS systems are configured by analysing input material, process requirements, contamination, desired output quality and future upgrade needs. This determines whether the line needs preparation, drying, extrusion, filtration, compounding or additional stages.
Services And Support
Yes. MAS supports customers during commissioning so the installed equipment or recycling line can be brought into operation with technical guidance.
MAS provides maintenance-related support for its technologies and systems. Maintenance planning helps protect process reliability and long-term equipment performance.
MAS support can include remote assistance where the installed technology and service setup allow it. Remote support helps customers address technical questions without waiting for an on-site visit.
Spare parts support is part of the lifecycle approach for MAS technologies. Customers should confirm spare parts planning and availability for their specific installed equipment.
Existing lines can often be reviewed for upgrade potential. Possible upgrades may include filtration, drying, compounding, automation or other process improvements depending on the installed system.
Operator guidance and training should be discussed as part of commissioning and service planning. Training helps teams understand process control, maintenance routines and safe operation.
Sustainability And Circular Economy
Plastics recycling supports the circular economy by returning plastic material to productive use. High-quality recycling depends on reliable preparation, extrusion, filtration and process control.
Recyclate quality determines whether recycled material can be used in new manufacturing applications. Stable processing, contamination removal and suitable compounding all support better material value.
Recycled plastics can replace virgin material in suitable applications when material quality, regulatory requirements and product performance needs are met. The process must be matched to the target use.
Recycling efficiency can be improved by preparing material correctly, reducing contamination, stabilising extrusion, filtering the melt and designing the line around the real input stream.
Complete recycling lines connect the stages that determine material recovery and output quality. Integrated process design can make recycling more reliable and help preserve material value.
Verified project examples should be reviewed on the MAS case studies page when available.
