Latest Research Shows Large CO2 Savings For Axion’s Recycled Polymers

Carbon Footprint Review

Recycled polymers have significantly lower carbon footprint than oil-based virgin plastics – up to 89% for ABS – according to latest research by Axion Polymers.

The Manchester-based plastic recycler’s 2017 Axpoly® Carbon Footprint Analysis also reveals a carbon saving of 82.5% for recycled (HIPS) and 73% for recycled (PP).

The CO2 savings are large, according to Axion. Their team calculated that using just one tonne of Axpoly ABS instead of virgin material to make goods would give a saving of 3,380 kgs of CO2 – equivalent to a 40ft articulated lorry transporting the material 2,272 miles. On one full-load, the same lorry could be driven 45,500 miles or almost twice round the world on the equivalent CO2 savings.

Axion Polymers produces three types of recycled polymer from their advanced re-processing plants for Automotive Shredder Residue (ASR) derived from End of Life Vehicles (ELV) and WEEE. These are Axpoly® PP (polypropylene), ABS (Acrylonitrile Butadiene Styrene) and HIPS (high impact polystyrene) and are the most common plastics used in the automotive and E&E markets over the past 15 years.

lower carbon impact

The Axpoly® polymers can be used as a direct replacement for virgin polymer, or combined with virgin polymers to produce a high-grade polymer with recycled content that can be used in demanding applications.

The new study was prompted by recent investment in more efficient separation processes and improving throughput that has increased the yield of finished polymers. Axion based its methodology on the similar process stages to making oil-based polymer from crude oil to allow a direct comparison between the process routes and resulting carbon emissions.

The calculations were done by Axion’s Head of Engineering & Research, Richard McKinlay who says: “These ‘new metrics’ of the circular economy are the numbers that need to be considered by designers and specifiers of polymer materials when selecting plastic for use in new parts and components on all types of consumer goods and vehicles.”

Axion Director Keith Freegard explains: “What we’ve confirmed is that as our process technology has developed, our throughput has increased, our efficiency has improved and our power consumption per unit output has got much better with lower wastage and better yield; then that all pays off in an improved carbon footprint per tonne of output product.”

He continues: “This proves to me that actually using a carbon footprint metric is a really good way of tracking if your process is an efficient conversion of waste into finished product.”

Keith says customers can benefit from their analysis by demonstrating the carbon savings credited to their finished moulded products. “We’ve already heard from some customers who are excited about having a new updated number on the savings that accrue to them. We’re also happy to provide a bespoke carbon analysis on their operations so they gain the benefit from the work we’ve done of measuring our own carbon footprint.”

Referring to recent calls by major petrochemical companies for a ‘carbon tax’ (Click Here) to accelerate the transition to a circular economy and minimise environmental impact, Keith suggests that now would be a good time to apply this type of metric in the form of taxation on major manufacturers.

He adds: “Of course, if everyone along the manufacturing chain was picking up their tax for the carbon impact of what they did, there’d be a huge financial driver for producers to switch from virgin polymers to recycled grades. One day that will come!”

Axion Polymers is part of the Axion Group that develops and operates innovative resource recovery and processing solutions for recycling waste materials. The Group works with a wide range of clients within the recycling and process industries on the practical development of new processing and collection methods.
