Pelletising polypropylene: Applied Machinery

Daniel Fisher, Applied Machinery Project Manager, wants to revive domestic plastic recycling through sustainable Polystar pellets. 

The recycling conversation is becoming more layered and complex by the day, with notoriously problematic plastic often taking centre stage. While the problem of plastic waste is widely understood, manufacturing processes still heavily rely on the material.

Daniel Fisher, Applied Machinery Project Manager, says responsibly processing plastic while keeping up with demand requires straightforward remanufacturing options. He adds that one such option is recycled plastic pellet production.

Daniel says to implement a wider uptake of recycled pellets in the manufacturing industry, resource recovery operators need simple-to-use equipment.

“When dealing with a difficult waste stream such as plastic, it’s common for operators to think that a more complex system will perform better,” Daniel says.

“But as the exclusive Australian distributor of Polystar Machinery, Applied Machinery is committed to supplying customers with straight forward and cost-effective solutions.”

Applied Machinery has worked with the Taiwan-based recycling equipment manufacturer for four years.

Polystar manufactures a range of one-step machines designed to reprocess multiple waste streams, notably polyethylene and polypropylene flexible packaging material.

Polystar technology is designed to be simple to operate and easy to maintain.

“The recycled output result is high-quality plastic pellets that can be repurposed back into manufacturing straight away,” Daniel explains.

“The pellets save waste disposal costs by producing a saleable product, while also offering an alternative to raw material extraction.”

Applied Machinery can offer customers the full suite of Polystar products, including the Polystar HNT and the Polystar Repro-Flex.

“HNT machines are typically suited for flexible, post-industrial film and have the added benefit of being able to produce quality pellets from even the most heavily printed packaging material.”

Daniel says the Polystar Repro-Flex is suited to multiple recycling applications including plastic bags, film scraps, bubble wrap, shrink film and laminated film.

“Repro-Flex machines also work well for post-industrial film waste, as the system can process washed flakes, scraps and pre-crushed rigid plastic waste from injection and extrusion,” he adds.   

Both the HNT and Repro-Flex feature an integrated cutter compactor, which removes the need for pre-cutting.

“The cutter compactor, which generates frictional heat during the compacting process, also helps remove moisture from the material.”

According to Daniel, eliminating moisture is a particularly significant feature when generating recycled plastic pellets, as even minimal water can render a whole batch unusable.

Daniel says the integrated Polystar system also eliminates the need for separate crushers and the common problem of inconsistent feeding.

“The integration of the cutter compactor and extruder ensures extremely fast and stable feeding, as the tangentially connected extruder is continuously filled with pre-compacted material.”
