Challenges Facing Mechanical Recycling of Plastic Waste

Another peer-reviewed study confirms what an increasing number of researchers have been warning for years: Mechanically recycled polyester releases more microplastic fibers than virgin polyester — and the problem intensifies with repeated recycling cycles. In this work, fabrics containing mechanically recycled polyester were subjected to one, two, and three recycling loops. The results are unambiguous. While a single recycling cycle may appear “acceptable” under current testing regimes, second and third recycling cycles resulted in up to a 4–6 fold increase in microfiber emissions compared to virgin polyester. mechanically-recycled-textiles-a-source-of-microplastic-fiber-emissions.pdf None This is not an isolated finding. It is not “one or two studies.” It is a pattern that is now well established across the literature: mechanical recycling degrades fiber integrity, increases yarn hairiness, accelerates fragmentation, and ultimately amplifies microplastic pollution. Even more critically, the study shows that high microfiber release persists across multiple recycling cycles, rather than declining. This is a clear signal that the issue is systemic, not transitional. The idea that “we just need to recycle more times to close the loop” collapses under empirical evidence. Perhaps most concerning from a regulatory perspective is this: 👉 Dry abrasion (real-world wear) generates substantially more microfiber emissions than laundering, yet policy and standardization efforts continue to focus almost exclusively on washing-machine-based assessments. This means we are likely underestimating emissions by design, while simultaneously promoting recycled textiles as an environmental solution. So let’s be clear: ♻️ Recycling, as it is currently implemented for synthetic textiles, is not a solution to microplastic pollution. At best, it is a partial waste-management strategy. At worst, it externalizes a different environmental cost — one that enters air, water, soils, food webs, and human bodies. If textile circularity policies do not explicitly account for microfiber release across the full life cycle, they risk becoming green narratives rather than evidence-based interventions. The question is no longer “Should we recycle?” The question is “How much environmental harm are we willing to ignore in the name of circularity?” https://lnkd.in/dyBSqeHU

Why Recycling Plastic Film is Challenging (and Why We Do It Anyway) Recycling flexible film into a product that can be used again in flexible packaging is a complex process.  Despite the challenges, NOVA Circular Solutions is making significant strides to increase the supply and improve the quality of recycled polyethylene (rPE) made from flexible films to enable circularity.  Here's why recycling plastic film is so challenging and why we continue to pursue it. The Challenges of Plastic Film Recycling 1. Securing the Feedstock: Plastic films are thin and light and often intermingled with other materials making collection and sorting a critical task. Ensuring a consistent supply of clean plastic film feedstock requires either meticulous manual sorting or state-of-the-art automated sorting technology to ensure the consistency of feedstock necessary to produce a high quality rPE. 2. Specialized Equipment: Recycling plastic film requires specialized processing equipment that can shred, wash, dry and extrude the thin, flexible material without causing jams at high production rates. 3. Quality Control: Maintaining the quality of rPE to meet industry standards for flexible packaging requires robust manufacturing practices and sophisticated quality control testing. 4. Regulatory Compliance: Navigating the complex web of regulations governing plastic recycling for food-grade materials requires meticulous attention to detail and adherence to stringent traceability standards. It is important to make sure rPE is certified and compliant for its intended use, especially for food contact applications. Despite these challenges, the benefits of recycling plastic film are undeniable: 1. Environmental Impact: Recycling reduces the amount of plastic waste in landfills and oceans, mitigating pollution and conserving natural resources. 2. Economic Benefits: Creating a market for recycled plastic film can stimulate economic growth and create jobs in the recycling industry. Our Approach NOVA Circular Solutions is at the forefront of tackling these challenges. Our first mechanical recycling facility for PE film is now online. The SYNDIGO1 facility located in Connersville, IN represents a significant step forward in the recycling industry, aiming to produce high quality SYNDIGO recycled PE. We employ cutting-edge technologies and rigorous manufacturing processes to ensure the quality and safety of the recycled products. By working closely with regulatory bodies and industry partners, NOVA Circular Solutions is setting new standards for plastic film recycling. While recycling plastic film is challenging, the environmental and economic benefits make it a worthwhile endeavor. NOVA Circular Solutions is leading the way, demonstrating that with innovation and commitment, we can overcome these obstacles and make a positive impact on our planet.

PLASTIC RECYCLING We all realise that the the recycling system itself is deeply flawed, or at least suspected this. Based on a recent dataset complied by Visual Capitalist we can see that most plastics are incompatible, making sorting costly and inefficient. Only PET (#1) and HDPE (#2) are widely recycled. In short, once most plastic products are created and reach the end of their usefulness, they’re tough to repurpose. The economics of recycling are also stacked against success. Virgin plastic, often subsidized by fossil fuel subsidies, is cheaper than recycled plastic. This price disparity discourages the use of recycled materials. Furthermore, the rise of flexible packaging—those lightweight packets for snacks and food—exacerbates the problem. These multi-layered packets, while convenient, are incredibly difficult to recycle due to contamination and complex composition. For instance we can see from the dataset that The United States is the world’s largest plastic polluter amd further only recycles a a meagre 5% of its household plastic waste. Additionally, a staggering 91% of plastic waste is still incinerated, landfilled, or mismanaged (e.g. dumped into the ocean). The graphic below, using OECD data shows a clear picture of the situation. Addressing the global plastic crisis requires systemic and mindset change involving interventions that are likely to include; 1. Bans on single-use and/or unrecyclable plastics 2. A global plastics treaty 3. Phasing out fossil fuel subsidies 4. Implementing and strengthening responsibility programs for plastic producers; 5. Extended Producer Repsonsibilities (introduced in the UK in 2023, which required large organsiations to; - review recycling obligations - fund equivalent recycling obligations as a % of waste reported (Packaging Recycling Notes: PRN's & Packaging Export Recycling Notes: PERN's) - Provide evidence of the above - From October 2025 pay waste disposal costs - PRN's & PERN's must eqaul 83% of the total weight declared - 1 year and 1 month for reproting a full year waste amount. There is also coverage of this in the OECD Environment Policy Paper No41 April 2024 (Link: https://lnkd.in/eSAv8Mtt ) The issues often occur within our #supplychains and #production processes that are often not originated by the end users but those that produce, cause to produce or manufactire goods for consumption. A fact that is covered by the #UNSDG12 (Responsible Production and Consumption) a concept that embraces a whole societal ecosystem.

⚠️ Major warning for Europe’s plastics recycling industry: Capacity is collapsing at an unprecedented rate. ♻️ According to Plastics Recyclers Europe (PRE), weak demand, rising costs and red tape are pushing facilities out of business, with the UK among the hardest hit. Here's what we know: ➡️ Europe is on track to lose 1 million tonnes of recycling capacity by the end of 2025 compared to 2023. ➡️ Between January–July 2025, almost as much capacity was lost as in all of 2024 – 3x higher than 2023. ➡️ The Netherlands, Germany and the UK are seeing the sharpest downturn. ➡️ UK closures include Viridor’s Avonmouth & Rochester sites, and Biffa’s Sunderland plant (39,000t capacity). ➡️ Investment is shifting to PET, with Veolia’s £70m Shropshire facility (2026) and Enviroo’s Ellesmere Port site (2027) in the pipeline. 💡 Why it matters: Industry leaders are clear, without urgent government intervention, the UK risks losing critical recycling infrastructure, jobs and progress on environmental targets. 📋 PRE is calling for action on: - Trade and market defence against low-priced imports - Consistent EPR rules and strict certification - Faster permitting and reduced bureaucracy - Affordable clean energy for recyclers - Stronger customs controls & targeted investment incentives As Figureheads at both Biffa and Veolia have highlighted, this isn’t just about business impact, it’s about safeguarding the UK’s ability to recycle its own plastics, reduce reliance on imports and meet climate commitments. 🌍 🤝 The question now: will policymakers act quickly enough to protect the future of domestic and European plastics recycling? #plasticsrecycling #circulareconomy #sustainability #recyclingindustry #eurecycling #ukrecycling #plasticwaste #greeninnovation #ukeconomy #resourcerecovery #wastemanagement
