Plastic chip management:
from chips to briquettes

Compaction of plastic chips into briquettes: less volume, lower costs, greater value

Packaging, production scraps, molding waste, expanded material: plastic waste is among the most voluminous and costly to manage in manufacturing companies. It occupies large spaces, costs to collect and is subject to increasingly stringent regulations.

COMAFER Dinamic Series and Special Series briquetting machines compact the most common industrial polymers into dense cylindrical briquettes, reducing volume by up to 90% and cutting disposal costs. The result is material ready for mechanical recycling or energy recovery.

Plastic briquetting requires specific evaluation for each polymer: temperature, density and flow characteristics vary significantly. Send us a sample for a free test in our R&D laboratory.

 

Which plastics can be briquetted?

COMAFER has successfully tested all major categories of plastic materials.

Polyolefins

Polyethylene (PE-HD, PE-LD), polypropylene (PP), plastic pods

Common thermoplastics

PET, PMMA (polymethyl methacrylate), solid polystyrene (PS)

Expanded materials

EPS (expanded polystyrene), expanded polyurethane (PUR)

Synthetic fibers

Nylon, polyester, polypropylene fibers, plasticized fiberglass

Thermoplastic materials with low melting temperature (such as low-density polyethylenes) require careful heat management during compaction. For thermosetting or mixed materials, a preliminary test is necessary. Contact us before purchasing.

FAQ

Frequently asked questions about briquetting

Can expanded polystyrene (EPS) be briquetted?

Yes. EPS is one of the materials with the greatest benefit from briquetting: it has a bulk density of only 10-20 kg/m³ in loose form. The Special Series with vertical pneumatic cylinder effectively conveys the material into the compaction chamber. Volume reduction reaches 90%: a volume of EPS that fills a warehouse is reduced to a few pallets of briquettes.

Do the high pressures of briquetting melt the plastic?

Briquetting is a cold mechanical compaction process, not a thermal process. The plastic is compressed, not melted. The heat generated by friction is limited and not sufficient to bring common polymers to melting temperature. For materials with low melting point or under intensive working conditions, a barrel cooling system is available.

Can plastic briquettes be mechanically recycled?

Yes. Homogeneous plastic briquettes (same polymer) are material suitable for mechanical recycling. Briquetting does not alter the chemical characteristics of the polymer. It is important to separate polymers before briquetting to maximize the value of plastic chips. Mixed plastics have lower commercial value.

How is plastic with additives or fillers managed?

Plastics with mineral fillers (fiberglass, talc), colorants or additives briquette normally. Abrasive fillers (fiberglass) accelerate wear of contact components: versions with reinforced wear-resistant components are available. Report this during the quotation phase for the correct configuration.
