Collaborate to create end markets for recycled polymers

Collaborate to produce end markets for recycled polymer

Collaboration between injection moulders and manufacturers, and plastic recyclers is key to creating new end markets for recycled polymers, meet rising demand for recycled content and improve the overall economics of recycling.

With more manufacturers, especially those in the automotive and electrical sectors, looking to increase recycled content in new goods, this presents opportunities for injection moulders to consider alternatives to virgin material.

At Axion’s two processing sites, plastics recovered from end-of-life vehicles (auto shredder waste) and waste electrical goods are refined into high-quality engineering polymers that match virgin material quality. Our bespoke recycled Axpoly® and Axplas® polymers can be tailored to suit clients’ specifications for use in a wide range of new products.

The economic feasibility of recycling depends upon stable end markets, that justify the cost of processing. Moulders who work with recyclers on understanding physical polymer properties, and crucially, engage in practical trials to understand the suitability of a recycled polymer in new applications can gain a competitive advantage in emerging circular economy markets.

Ambitious aims on the recycling of packaging, and a growing desire to recycle more non-packaging products including plastics from End of Life Vehicles and Waste Electronics and Electrical equipment are driving manufacturers to seek new solutions and incorporate more recycled content.

Fear over a proposed tax on packaging without recycled content being possibly extended to other markets is also cited as a driver for the desire to include recycled materials in new goods.

Some closed loop recycling exists, primarily in PET and HDPE packaging. Although closed loop recycling is not vital, if it can be achieved it allows for the same grade of polymer to be reused in the same application. This removes some of the technical barriers of using recycled content.

However, in many cases, closed loop cannot be achieved because products may be collected in a mixed stream, where separation of different polymer grades is not technically or economically possible. In this case, manufacturers need to consider using alternative polymer types or blends if they want to increase recycled content.

This brings a potential technical barrier.

In many cases, a moulded product is designed to use a specific grade of polymer with very specific properties. The company that produces the moulded product may not be involved in specifying the material, and so will be reluctant to use any polymer that does not conform to the exact original specification.

The potential technical barrier then becomes a “resistance” to use recycled content due to past perceptions about its ability to meet virgin material specifications and perceptions about the quality of recycled materials. In many cases however, products do not need such rigid specifications, and in reality, a wide range of different grades of a polymer or even different blends of polymers may work well in certain applications.

Blending PE and PP from plastic film to use in injection moulding of “PP” products is a prime example of what can work successfully. Products such as crates, bins and buckets can even benefit from a PE/PP blend as the properties can complement each other.

Axion Polymers Business Development Manager Mark Keenan points out that although physical properties of recycled polymers are important to measure, conducting trials using the material provides a more detailed picture.

He says: “Moulders should work with recyclers to ensure that the recycled polymer is as suitable as possible for an application. At Axion Polymers, we work with our customers to get recycled content into their products or help them use a different polymer formulation altogether.”

“We assist moulders at every step, right through to setting up their machinery to enable them to use alternative recycled polymers. Practical trials are the only way to truly understand the suitability of a recycled polymer.”

Mark concludes: “With the desire to recycle more and more materials, end markets need to be continuously developed. Full supply chain collaboration can ensure there are stable end markets and provide the “pull” effect to boost the overall economics of recycling.”

RecoMed PVC takeback scheme launches new website

RecoMed, the PVC takeback scheme for single-use medical devices, has launched its new website – – in response to rising interest from the healthcare sector in reducing and recycling plastic waste.

Set up in 2014, RecoMed provides an alternative, sustainable disposal route for waste medical items, such as oxygen masks and tubing, made from high-quality medical grade PVC. The new website contains all the information potential participants need, including how RecoMed works, case studies and latest news, which is also shared on Twitter via @RecoMedUK.

Currently 37 NHS and private hospitals are actively participating in the scheme across the UK – from Plymouth to Newcastle – with more set to join in the coming months. Run by Axion in partnership with the British Plastics Federation (BPF), RecoMed is funded by VinylPlus®, the voluntary sustainable development programme of the European PVC industry.

The first scheme of its kind in Europe, RecoMed coordinates every step in the recycling journey – from providing PVC collection bins in hospitals to delivering the shredded plastic to specialist recyclers where it is turned into horticultural products, such as tree-ties.

To date nearly 22.5 tonnes of PVC has been recycled – the equivalent of about 747,000 oxygen masks. The majority of this total, more than nine tonnes, was collected and recycled in 2019 alone.

Mick Claes, Senior Consultant at Axion and project leader for RecoMed says the new website is very timely, given the current ‘huge swell of public interest’ behind reducing plastic waste.

Welcoming the new website, he comments: “The scheme is growing, and we are seeing keen interest from healthcare professionals who are very aware of plastic waste generated through their procedures, such as anaesthetics for example.

“That’s why we have provided more detail on what RecoMed can accept, the benefits to participants and how to make the scheme a success in your hospital. People are used to recycling at home and they want to do this at work too.”

Around 8 million UK hospital procedures each year result in the disposal of single-use PVC masks and similar devices that could safely be recycled. These devices are currently sent to landfill or incineration, wasting resources and costing the NHS substantial sums in waste management.

Outlining future plans for RecoMed, Mick says partnerships with other healthcare sector stakeholders are being discussed to facilitate the rollout to more hospitals. He adds: “We are also looking to partner with other PVC product manufacturers and find new ‘circular’ applications for the recycled material. Our goal is simple: to increase medical PVC device recycling rates.”

Recovinyl: UK is top contributor to PVC recycling scheme

The UK is second in Europe (behind Germany) in collecting and recycling waste PVC with a total of 137,989 tonnes recycled here in 2018 across all PVC recycling formats. Of this total, PVC window profiles accounted for 73,703 tonnes, according to latest industry figures.

The UK’s sizeable effort represents around 19% of the 739,525 tonnes of waste PVC recycled throughout Europe in 2018 – a new record high. Across Europe, window profiles and related building products accounted for 44% of the total PVC recycled.

Recovinyl®, the PVC industry’s recycling scheme, was the largest contributor to this total and registered a total of 734,568 tonnes of PVC waste entirely recycled in Europe in 2018 – a 15.6% increase from 2017. In Europe, the demand for recycled rigid PVC is currently very high, indicating the potential for further strengthening collection and recycling schemes.

Two new UK Recovinyl recyclers

Recovinyl has further sharpened its certification and audit schemes to ensure maximum reliability of collected data and of recyclates traceability, both from recyclers and converters. Over the last 12 months, two new recyclers who focus on rigid PVC have joined the UK Recovinyl network – Tecvyn in Hull and Recycling PVC in Manchester, making a total of 24 accredited recyclers across the country. While across Europe, 11 new recyclers have signed up in the first half of 2019.

Axion is Recovinyl’s Regional Representative for the UK. Welcoming the ongoing upwards PVC recycling trend, Richard McKinlay, Axion’s Head of Consulting says: “Recovinyl is a great success story and there’s still a huge demand for recycled PVC. Much of what is being collected is post-consumer material and we’re doing a really good job in the UK, but we’d like to collect and recycle even more to meet the demand. That’s why it’s important to recycle these frames, for all the right reasons.”

Optimisation in cutting technology has resulted in fewer and smaller post-industrial off-cuts for recycling, as Richard notes: “Fabricators have become more efficient at cutting profiles and getting more frames out of their bar lengths. As people get better at reusing offcuts or minimising off-cut material, it’s become even more important to capture more post-consumer material for recycling.”

PVC recycling can ‘lead the way’

Hinting that construction is the next sector after packaging to come under scrutiny in terms of waste, Richard says PVC’s now-established recycling infrastructure can ‘lead the way’ in setting an example for the treatment of other waste construction materials.

For fabricators and installers, recycling PVC makes ‘economic and environmental sense’ says Richard: “The PVC recyclers will pay for good quality material, so there’s an economic incentive for fitters and with a recycling network across the UK, there’s an outlet; no need to throw it in a skip. Everyone can do their bit to protect the environment and even the smallest installation company should look at how they can recycle and who their nearest recycler is.”

Segregating PVC frames and off-cuts is important, adds Richard, as this helps to maintain quality and the market value of the material.

Simon Scholes, Managing Director of VEKA Recycling Ltd, one of the first Recovinyl recyclers in the UK, observes that window companies, particularly larger fabricators, are generating less PVC waste. “Less production waste is a positive thing,” he says. “As the industry has become more professional, it is getting better at collecting waste PVC and sending less to landfill. That’s helping to bring sustainability to the industry as a whole.”

Simon adds: “The material is out there, and we can help companies of all sizes to recycle their waste PVC frames and off-cuts. People are catching onto recycling and attitudes towards this are improving. We’re going in the right direction!”

PVC can be recycled multiple times without any loss of performance and reused in many diverse new and long-life products from construction products such as windows to flooring and electrical components.

Cumulatively, almost 5 million tonnes of PVC have been recycled within the Vinyl 2010 and VinylPlus frameworks across Europe since 2000, with around 10 million tonnes of CO2 saved. Check out your nearest Recovinyl recycler at

Axion Polymers successfully renews ISO 9001 certification

Axion Polymers has successfully renewed its ISO management system certification at both its Manchester plastics recycling sites – and gained a new ISO18001 Health and Safety standard for the Salford facility.

Following an audit conducted by LRQA, Axion Polymers has been recertified for its ISO 9001 quality management systems at its Salford and Trafford Park sites. Based on seven quality principles, ISO 9001 certification covers all aspects of the plants’ operations, from manufacture to supply and customer service.

Axion’s Commercial Operations Manager Laura Smith comments: “We’re proud to have achieved renewal of our Lloyds Register ISO 9001 quality standards accreditation and this is testimony to the rigorous quality management procedures we have in place.

“Our customers can be assured that all Axpoly® and Axplas® products are manufactured according to the highest quality standards. Quality runs through everything we do.”

While the Trafford Park site has been recertified for OHSAS 18001, the Health and Safety management systems standard, it’s the first time that Salford facility has achieved this certification. OHSAS 18001 demonstrates a strict compliance with Health and Safety procedures.

Praising the team’s efforts, Axion’s General Manager Judith Clayman says: “Achieving this standard at both sites is a key goal for our company. The Health and Safety of our employees, subcontractors and visitors is our highest priority from their first footstep on site and subsequently throughout our entire operation.

“I am delighted that the whole team’s hard work has been rewarded with the certification. It demonstrates that robust implementation of policies, procedures and controls is in place to achieve excellent working conditions and workplace health and safety across the whole business. We will now be focussing our efforts on achieving ISO 45001, the new enhanced Health and Safety standard.”

Judith adds that Axion’s next step is to work towards achieving the environmental management standard ISO 14001 for both sites.

Axion welcomes ‘all-in’ Deposit Return Scheme proposal

Proposals for an ‘all-in’ deposit return scheme (DRS) for drinks containers are a positive move to encourage people to recycle more and associate a value with waste plastic and other materials.

Including cans and bottles made from plastics, aluminium, steel and glass would also help to increase capture of ‘recycling on the go’ materials.

Axion’s Head of Consulting, Richard McKinlay welcomes the ‘all-in’ approach because it removes the incentive for brands to offer discounted alternatives not included in the DRS scheme, such as water in cans instead of bottles. The alternatives, he says ‘may be more environmentally impactful’.

Commenting on Environment Secretary Michael Gove’s hints on the likely contents of the government’s Environment Bill due later this year, Richard continues: “I think a deposit return scheme is needed; especially from a quality point of view to ensure we’ve got a high-quality food grade PET stream that allows recycling back into the highest quality applications.”

“More and more brands and retailers are facing targets of including higher recycled content in packaging, yet currently we haven’t got the quantity or quality of the material to achieve that.”

Concerns have been raised that implementing a DRS will impact on existing kerbside collections as people will be encouraged to separate bottles from their household recycling to return them and claim their deposit back. Fewer numbers of polyethylene (PET) bottles in household collections would leave local authorities with the lower quality PET trays. With fewer PET bottles in the waste stream, the ones that are still there may be harder to sort and extract.

Consequently, more MRF infrastructure will be required to re-sort the waste stream for PET bottles. Investment in the recycling infrastructure will also be needed to handle the remaining PET pots, tubs and trays.

On the plus side, Richard says the DRS will deliver better quality bottles for recycling. “It will be possible to recycle more bottles into bottles, and potentially, trays into trays, increasing the amount of food grade rPET on the market. However, investment in the processing infrastructure will be necessary for that to work.”

Although the ‘all-in’ system will have many positives and will work towards creating a level playing field, there are issues that will need to be resolved. The inclusion of beverage cartons in the DRS should be considered, to remove the incentive for brands to switch to using them as an alternative. There will be hygiene issues with certain foodstuffs such as dairy so it may be prudent to exclude fresh milk packaged in natural HDPE.

Highlighting the need for wider reform, Richard concludes: “This initiative shouldn’t be seen as removing value from local authorities. Although there may be some impact, the bigger picture is that more material overall will be recycled back into high quality products. DRS should be implemented as part of a broader reform of how we manage and recycle packaging waste, which should include Extended Producer Responsibility to remove the cost burden from Local Authorities.

“We should not be afraid to move away from the existing waste management infrastructure which is inherently unable to deliver on the Circular Economy.”

Investment boosts recycling capacity for Axion Polymers

Further investment in Axion Polymers’ plastics recycling facility has increased waste processing capacity, as well as extrusion capability of its 100% recycled polymer grades. It is the first phase of continuing investment in the plant development.

Additional equipment has been purchased and installed at its Shredder Waste Advanced Processing Plant (SWAPP), Trafford Park, which has ‘de-bottlenecked’ part of the high-tech process.

As a result, the plant capacity has improved by over 30% per month, allowing increased volumes of auto shredder residue (ASR) from end-of-life vehicles (ELV) and Waste Electronic and Electrical Equipment (WEEE) to be processed into its high-quality Axpoly recycled polypropylene (PP) and ABS grades.

The greater processing capacity translates into a 20% increase in recycled polymers produced per month, enabling Axion to satisfy increased demand from the construction and automotive sectors for these materials.

Axion’s processes demonstrate a full circular economy approach; extracting and refining a high-quality engineering polymer from auto shredder waste and WEEE.

Operated jointly with S Norton, one of the UK’s leading ferrous and non-ferrous metal recyclers, the SWAPP facility, one of the most advanced of its type in Europe, has an annual capacity of 200,000 tonnes separating the non-metallic fractions (ASR or shredder ‘fluff’) from the equivalent of about 800,000 cars a year.

The plant delivers the 95% recycling and recovery rate for cars, creating a circular economic model for automotive materials. Axion’s high-grade Axpoly® recycled polymers can be used as a direct replacement for virgin polymer or combined with virgin polymers for use in demanding applications, including the automotive sector.

The SWAPP investment means increased volumes of infeed material for Axion’s Salford plant, which refines plastics extracted from ELV and WEEE. It supplies tailored polymers to suit specific end-user requirements, such as modified melt flow, impact resistance and tensile strength.

Axion Polymers Commercial Operations Manager Laura Smith says the new investment is ‘great news’, meaning that they can now satisfy more customer orders, adding: “Our customers benefit from our secure source of infeed material; it means we can reliably satisfy our customer orders. Because of the process modifications we have made, we are now able to supply greater volumes of Axpoly polypropylene and ABS grades every month.”

Praising the team’s hard work, Axion’s General Manager Judith Clayman adds: “They all pulled together to design and install the plant modifications as efficiently as possible and I am very pleased with the result. The investment in the SWAPP plant shows Axion’s commitment to continuously improve and optimise its unique process for recovering materials from end of life vehicles and mixed WEEE appliances.”

I’m very proud of our team that is driving the circular economy by working together to meet the customers’ diverse needs in every respect.”

The Awards ceremony will be held at The Hilton, Park Lane, London on June 27th 2019.

Axion Polymers welcomes proposed 500ppm decaBDE limit for recycled plastics

A 500ppm limit of flame retardant decaBDEs within recycled compounds and articles that looks set to be agreed by the EU Commission soon has been welcomed by Axion Polymers as ‘leaving the door open’ for plastic recycling and the use of recyclate in new products.

The proposed 500ppm level in recycled plastics will be a ‘workable’ solution, although it will be tougher to achieve than the proposed 1,000ppm in line with most REACH and RoHS regulations. Virgin polymers have a 10ppm limit.

“Professional companies that have spent time trying to inform and address the EU Parliament in the management of decaBDEs in recycled plastics will welcome the recast of the EU directive as a sensible way forward,” comments Keith Freegard, Axion’s Associate Consultant.

He believes that advanced separating, sorting and refining plants can hit the 500ppm limit for output plastic resins, saying:  “It also means we can continue recycling plastics at our Trafford Park and Salford facilities, and crucially, that our customers can continue to use recycled plastics in eco-design components along circular economy principles.”

However, while the 500ppm is a workable compromise, the planned review in the EU after just two years could present further business challenges for recyclers, according to Keith, who believes this timescale is ‘too short’ for long-term projects.

He points out robust industry evidence about treatment of previously-banned legacy additives, such as those in the automotive sector. Research shows that it takes approximately 10 years for the effect of a ban in new products to be seen in the infeed material at the recycling plants.

“For a review of the acceptable level of decaBDEs in recycled plastic mixtures, industry should show the regulators how the rate declines over time as eventually these legacy additives are mostly eradicated in new components,” continues Keith.

Since before 2012 when decaBDEs entered the REACH SVHC list, the effect from not using these chemicals was already being seen. With car manufacturers reducing their use since 2008-2012, Keith asserts that a similar ‘ramp down’ would be evident in waste plastics but delayed by the average lifetime of a vehicle – around 13 years.

“Hence recyclers may well be seeing trace levels of decaBDEs tail off from 2020 to 2025 and onward to 2030. Any review must be based on firm evidence from European recyclers about how detected levels are changing with time, which could be used to estimate a scientifically-based ramp-down rate for mixtures and articles.”

The United Nations Basel Convention are meeting at CoP 14 in Geneva at the end of April, where they will address a set of treatment guidelines for the WASTE plastic raw materials which are the input feedstock to advanced recycling processes inside Europe and also exported around the world as waste raw materials.

Expressing concerns about the ‘sometimes high levels’ of decaBDE and other legacy additives within part-processed waste plastics sent for export, Keith highlights the need to set a ‘sensible and pragmatic’ level in these materials. The European CENELEC treatment standard uses 2,000ppm as the basis for deciding to ‘separately remove and treat’ waste plastics in WEEE products.

He argues that the level set for input waste streams to recyclers should be higher than that for output polymer products. This is because final, accurate separation of BFR-containing plastic particles is done using advanced technology in refining plants.

Allied with this should be a tougher regime for the global movement of waste plastics that do not meet the strict controls. “Those materials should be processed in the domestic market, ensuring banned chemicals are removed and supporting further investment in large-scale technical plants in Europe,” continues Keith.

He warns that exporting banned flame retardant plastic to Asia, without proper controls in place, risks ‘cheap, uncontrolled’ imports back into Europe of goods in which the banned chemicals have not been removed.

Concluding, he asserts that setting ‘sensible and pragmatic’ levels for decaBDE limits in waste plastics moved across the world would:

  • Ensure a ‘level playing field’ for high-tech recyclers
  • Stop the escape of valuable resources to other countries
  • Help to ensure that imported goods made with recycled WEEE or ELV plastics meet EU safety standards
  • Encourage much-needed investment in European and UK recycling infrastructure, further developing the transition to a circular economy for plastics

Keith adds: “How the EU will implement the findings of the Basel Convention on waste plastic controls remains to be seen. We need less export of poorly-segregated, shredded mixed plastic waste from WEEE and ELV where the levels of legacy additives are difficult to measure and probably not very well recorded.

“And we need more reasons to invest in dealing with our legacy additive-containing waste plastics at home using best available technology.”

Axion Polymers: ‘Water’ way to use recycled polymer

Axion Polymers overcame a series of challenges to prove the concept of using its 100% recycled polymer in clients’ stormwater drainage products. Mark Keenan, Business Development Manager explains how we did it.

Water resource management has become more important in recent years as our changing climate delivers more unexpected rainfall events with the associated need to control localised flooding.

Worth an estimated £3 billion, this sector is growing and presents opportunities for cost-effective, yet sustainable products. As the market potential has developed, we have worked with a number of UK-based building and construction products manufacturers to demonstrate the commercial feasibility of replacing virgin polypropylene (PP) with 100% recycled polymer in water attenuation chambers.

These products are designed to retain flood water in underground chambers from where the excess water can drain away slowly or be stored and pumped out for future use in times of drought or irrigation purposes.

There is a range of shapes and sizes of water attenuation chambers. Some are multi part units and some are crates with lids. Our focus was to assess whether our recycled polymers, derived from end-of-life vehicle plastics, would work for the larger crates.

Project challenges

Over a 12-month period, there have been several challenges, which the team overcame successfully through extensive testing and trials using different polymer formulations.

Our high-quality 100% recycled Axpoly® plastics are mechanically separated at Axion Polymers’ Shredder Waste Advanced Processing Plant (SWAPP) in Manchester. They are further refined at our Salford polymer compounding site where well-equipped lab facilities enable us to carry out extensive tests and trials using different polymer blends.

While Axpoly recycled polypropylene has a consistent set of properties making it an excellent choice for certain applications, the standard grade had to be modified to meet the structural strength requirements for the water attenuation chambers.

As the crates are stacked on top of each other, they require a hefty load bearing capacity. Our first challenge was meeting the specifications for structural strength. It takes several trials and different modifications until we achieve the right formulation, making sure that the standard deviation is very low on the product batches, so that it successfully passes external tests for compression strength and consistency.

We have already sold 1500 tonnes of Axpoly® polymer that has so far produced thousands of water attenuation chambers.

Environmental credentials

The product’s recycled polymer content and environmental credentials are a big selling point for customers. This is a plastic that previously would have been landfilled, so by being given a second life as a useful, sustainable and commercially-viable product, it is a great example of circular economy principles.

The clients appreciate our expertise in overcoming considerable technical challenges to deliver commercially-viable products using material that is ‘fit for purpose’. They also appreciated our involvement at every stage of the process, including attendance at all the trials. This inspires confidence in both parties that our material is going into a product that works.

Ultimately, we fully achieved the clients’ objectives of proving the concept of swapping from virgin material to recycled polymer for their products. The products work well, work above the specification limit, have passed all external tests and – just as importantly – sell well.

Going forward, our clients have seen the potential for using recycled content and can consider the option of further developing and investing in their products, including new injection-moulding tools. For our part, we have demonstrated how we can work with clients, helping them technically and commercially to realise their sustainable product visions.
