In recent years, the recycled plastics market is shifting from low-cost alternatives to high-quality recycling promoted by environmental protection and carbon reduction. Argus interviewed Guo Jiawan, chairman of Guangxi Guolong, and Arnold Wang, founder of Shichai Environment, on the following topics before the Second International Rigid Polyolefin Recycling Summit hosted by Shichai Environment:
- Prospects of China’s recycled plastics exports
- Food contact applications of recycled plastics
- EU’s “mirror-clause” in the Single Use Plastics Directive, etc
How much demand do you see from export markets for your products, what are the key export markets, and for which products and end-use applications (rPET, rHDPE, rPP, Packaging grades)?
Guo: The application of recycled plastics in the packaging market is mainly driven by the demand from international brands. Large brands use environmentally friendly recycled products as a way to actively fulfill their social responsibility and promote the recycling and utilization of waste plastics through their actions. In the Chinese market, international brands have been testing and trialing small batches of recycled plastics over the past two years. In the Southeast Asia, Hong Kong and Macau markets, they have begun to introduce recycled plastic packaging products. Many international brands also have production sites in China, and their export products have started to use recycled plastics. In the personal care sector, they primarily use rHDPE and rPP, while in food packaging, rPET is the main material, all of which must meet food-grade requirements and obtain FDA or EFSA certification.
Most participants are focusing on food contact recycled materials, but China currently does not allow recyclates to be used in food-contact applications. In such a situation, how should Chinese recyclers develop their business? Would pyrolysis be an appropriate approach for Chinese recyclers to look towards?
Wang: Currently, the main applications for high-value products from Chinese PET recycling enterprises are textile fibers, industrial yarns, and other non-food grade uses. Food-grade rPET products can also meet specific needs in personal care products, and other food-grade rPET supplies include exports to Hong Kong and overseas markets.
Pyrolysis is still in the exploratory stage in China, and several commercial projects have been announced this year, but their operation will take some time and still requires market validation. On August 27-28 this year, we will have an International Rigid Polyolefin Recycling Summit in Shanghai, which will include topics related to chemical recycling and pyrolysis. Those who are interested are welcome to follow and participate.
The EU is mulling a “mirror-clause” in the Single Use Plastics Directive which would mean that recyclers from outside the EU that are sending material to the EU to count towards our recycled content targets will be held to the same feedstock, process and environmental targets as European recyclers. How do you expect this to develop and do you see any impact on your business?
Guo: [Complying with EU standards] is not difficult for Guolong Recycled Plastics, because the process technology, production equipment and environmental standards of Guolong are the same as those in Europe, as is the the use of PCR materials.
Over the past few years, Guolong have passed various tests, factory inspections, and production environment assessments required by more than twenty international brand companies, and safely met their requirements. But, if the EU pushes this policy, it might implement certification permits through factory inspections under a case-by-case basis, which might impose certain restrictions on many other recycling enterprises in China.
What is Guolong's future development target, and does Guolong plan to invest in chemical recycling in the near future?
Guo: After ten years of development, Guolong has now established sizeable capacity for producing recyclates for a range of different end-uses (see table). We have successfully implemented a business model that spans the entire industrial chain, encompassing both food-grade and industrial-grade products. Currently the company has no concrete expansion plans for the future.
| Recycling type | Capacity (t/yr) |
| Food-grade rPET | 60,000 |
| Food-grade rHDPE | 20,000 |
| Food-grade rPP | 20,000 |
| Pipe grade recyclates | 80,000 |
| Industrial grade rHDPE | 20,000 |
Do you expect to see a market start to develop for recyclates into the food packaging market in China in the near future (i.e. a change of regulation) and what other regulatory changes in China do you expect that could support the recycling industry?
Wang: China is currently researching the safety of using recycled materials in packaging applications, which includes not only recycled plastics but also recycled metals, such as whether recycled aluminum can be used for cans. The local market is also awaiting the issuance of relevant documents.
Presently, the government has introduced various policies such as the "trade-in" policy and the reverse invoicing policy, which have all promoted the expansion of the recycling industry. These allow recyclers to issue invoices to their waste suppliers (rather than the other way around), to enable recyclers to claim a VAT deduction even when the waste seller they are working with is too small to issue invoices. Government policy may also be directed towards waste classification in the future, this could be the direction for future government policy.
Of course, establishing a complete recycling system requires more implementation strategies and more time to explore development paths and undertake construction.

Argent to start production at new glycerine refinery
Argent to start production at new glycerine refinery
London, 3 October (Argus) — Biofuels producer Argent Energy is expected to commence production at its new glycerine refinery in early October, a source told Argus . The new Argent refinery, which is located at its Port of Amsterdam site, is Europe's largest facility dedicated to producing bio-based, technical-grade refined glycerine. The facility has a production capacity of 50,000 t/yr and will upgrade crude glycerine into 99.7pc technical-grade glycerine to supply the European chemical market, the company said. Technical-grade refined glycerine can be used in the production of epichlorohydrin, polyether polyol and anti-freeze, among other applications. Additionally, its use as a feedstock for biofuels generation, such as marine fuels, is being studied as it could offer a cheaper alternative to LNG and distillates. The Netherlands has the largest marine fuel sector in the EU. "Our entrance into the chemical market is driven by our goal to maximise product value and support the circular economy. By upgrading glycerine from our processes into a technical-grade product, we're giving the chemical industry a bio-based option they can confidently use in their own products," Argent Energy chief executive Louise Calviou said. The glycerine produced in Argent's new facility will be made via the biodiesel production route, with the product being certified under International Sustainability and Carbon Certification (ISCC) guidelines. Argent Energy currently has a capacity of 190,000 t/yr for waste-based biodiesel, with sites in Amsterdam and northwest England. The company plans to soon triple biofuel production at its Amsterdam site alone. By George Barsted and Carolina A.

California textile recovery bill signed into law
California textile recovery bill signed into law
Houston, 2 October (Argus) — California governor Gavin Newsom (D) signed a bill into law on 28 September that will establish the US's first extended producer responsibility (EPR) textile recycling program. The law (SB 707) requires producers of apparel or textile articles in California to create a producer responsibility organization (PRO) that will handle and recycle textiles and apparel across the state, under the supervision of California's Department of Resources Recycling and Recovery (CalRecycle). SB 707 is the first EPR system for clothing that has passed in the US and leaves a lot of leeway to the PRO and CalRecycle in implementing the law. It provides relatively few details about how the EPR program will work and does not set any minimum recycled targets. The law was written by California State Senator Josh Newman (D) and was supported by textile industry participants and recyclers. "To achieve (our corporate goal of becoming a circular business by 2030), we must partner with policymakers to support efforts in creating more circular systems for textiles and other products," IKEA US Sustainability Manager Mardi Ditze said following the bill's passage. "We applaud Senator Newman for leading a collaborative process with industry stakeholders on SB 707 and support efforts to increase textile circularity in California and across the US." The PRO is required to provide free textile recycling drop-off centers for residents of California, and CalRecycle is authorized to impose monetary penalties against producers for violations of the program's requirements under the bill. Producers will be expected to join an approved PRO by 1 July 2026, and the EPR system is planned to begin enforcement on 1 July 2030.

Unilateral action can tackle plastic waste: OECD
Unilateral action can tackle plastic waste: OECD
London, 2 October (Argus) — Only stringent global measures addressing production and waste management combined can come close to eliminating plastic leakage into the environment by 2040, a new OECD report says. The report — Policy Scenarios for Eliminating Plastic Pollution by 2040 — projects the impact of different policy measures, ranging from business as usual, through measures only aimed at boosting collection and recycling or only enacted in developed countries, up to global measures targeting both upstream production and downstream waste management. It concludes that global plastic production will grow by 69pc by 2040 — versus a 2020 baseline — if the current policy environment is maintained, whereas the recycling rate would only increase by around 5pc, resulting in a 50pc increase in the leakage of plastic into the environment. Combining measures aimed at curbing plastic demand — including production caps, development of re-use systems and increased design-for-recycling — with policies aimed at boosting collection and recycling of plastic waste could reduce virgin plastic production, boost recycling rates above 40pc and reduce leakage to near zero. In a scenario where OECD members enact measures across the supply chain while non-OECD nations focus on downstream measures, virgin plastic production would rise only slightly by 2040, from 2020, the report says. But it projects that there would still be more than 10mn t/yr of plastic waste leaking into the environment, compared with 20mn t in 2020. Furthermore, the report concludes that enacting measures across the supply chain will be the most cost-effective way of limiting the environmental impact of plastic waste. This is because upstream measures such as design-for-recycling will reduce the cost of improving collection and recycling, which will be higher in many non-OECD countries where existing waste management infrastructure is more limited. Global measures across the supply chain would cost 0.37pc of gross domestic product (GDP) in OECD countries and 0.62pc of GDP in non-OECD economies by 2040, the report projects, compared with over 0.5pc and nearly 1pc, respectively, if only downstream measures were implemented. "These costs exclude the avoided costs of inaction and should be considered in the context of vastly improved environmental outcomes", the report notes. Shaping the debate The release of the report comes ahead of the fifth and final scheduled round of UN negotiations to develop a binding global treaty to tackle plastic waste, which will begin in South Korea in November. In past sessions, there has been ongoing debate about the scope that the treaty should take. Some delegates, especially from countries with a reliance on plastic-producing industries, have so far favoured a focus on downstream measures and opposed caps on virgin plastic production. A recent change of tack from the US in support of production caps surprised many observers, but its impact on discussions will depend on how much leverage it is willing to use to convince others to follow suit. Discussions during the Intergovernmental Negotiating Committee on Plastic Pollution on 25 September in New York showed member countries are still far apart in terms of policy agreements, with frustration sometimes visible from a few diplomats about the lack of progress in certain areas. Negotiations up to this point indicate that achieving the OECD's ideal scenario for tackling plastic waste will be extremely challenging.

California enacts carpet recovery law
California enacts carpet recovery law
Houston, 1 October (Argus) — California Governor Gavin Newsom last week signed into law an extended producer responsibility (EPR) program for carpets that overhauls the state's carpet recycling program. The law establishes a minimum mandate for carpet-to-carpet recycling, requiring new carpets to contain at least 5pc recycled carpet by 2028. It also requires a visual mark to identify synthetic carpet and greatly increases fees for a producer responsibility organization (PRO) that fails to meet carpet recycling mandates. The National Stewardship Action Council, an organization that advocates for a circular economy, said that the law will make "critical improvements" to the state's carpet recycling program. The carpet recycling mandate is intended to avoid the "downcycling" of bottles into carpet, as bottles are more easily recycled than carpet. Since 2011, California has required consumers to pay a carpet stewardship fee to fund the Carpet America Recovery Effort (CARE), a manufacturer-run organization that collects and recycles scrap carpet. CARE told Argus in July that the bill as proposed would upend the institution by replacing it with an inexperienced PRO to manage carpet recycling. The revised bill that Newsom signed on 27 September allows CARE or another industry group to serve as a PRO that would manage the carpet stewardship program. The law increases state government scrutiny on the PRO and increases fines for mismanagement of the program. The author of the bill, California Assemblymember Cecilia Aguiar-Curry (D), said that the law was in direct response to CARE's mismanagement of carpet recycling, and would strengthen accountability and transparency for the program. "Even with constant intervention and enforcement actions by CalRecycle and the California legislature, CARE's failure to successfully manage California's carpet recycling program has resulted in more carpet in landfills, wasted consumer fee money, constant litigation with the state, and serious damage to recycling infrastructure in this state," Aguiar-Curry said. CARE did not immediately respond to request for comment. The bill previously included materials such as vinyl and polyurethane flooring as part of the EPR program, but those sections were removed after industry organizations complained about their inclusion in a carpet bill .
