Circular Economy in the PE Plastic Products Industry” 

Circular economy in the PE plastic products industry: reality or marketing myth?

The circular economy in the polyethylene (PE) sector is no longer a theoretical concept and has become a hard economic imperative by 2026. We are observing a fundamental shift: the cost of recycled PEBD and PEHD granulates in a number of European regions has already exceeded the price of primary raw materials, which completely changes the procurement logic for manufacturers.Экономика замкнутого цикла в отрасли пластиковых изделий PEtoday it is dictated not so much by the environmental agenda as by issues of business survival due to a shortage of raw materials and tightening carbon footprint standards. In our practice of introducing recycling lines, we were faced with the fact that companies that ignored the transition to a closed cycle in 2024 lost up to 18% of their margins by the beginning of 2026 due to the inability to meet retailers’ requirements for the content of recycled plastic in packaging.

This article is not a collection of general phrases about “ecology”. This is a technical analysis of how polyethylene recycling actually works, what technologies can achieve food contact quality (rPE food grade) and why standard solutions often lead to financial losses. We'll analyze data for 2025-2026 so you can make informed decisions about upgrading production or changing supply chains.

Technological barriers and solutions in polyethylene processing

The main problem facedCircular Economy in the PE Plastic Products Industry, is not about collecting waste, but about deep cleaning it and restoring the molecular structure of the polymer. Polyethylene high density (PEHD) and low density (PEBD) have different sensitivities to thermal history and contaminants. Unlike PET, which can be easily cleaned chemically, PE requires complex mechanical and physical-chemical processes to remove volatile organic compounds (VOCs) and product residues.

In our practice, we have seen many cases where purchasing a cheap extruder for granulation led to disastrous results. One of our clients in the Moscow region purchased a second-hand line without a high-vacuum degassing system. The result was that the resulting granulate had a persistent smell of rancid oil and contained microgels that destroyed the film when drawn. The losses amounted to more than 40 tons of products that had to be disposed of. This case proves: savings at the stage of extraction of volatile substances kills the entire circular economy project.

Critical Steps in the Recycling Process

To obtain a high-quality regranulate, the process must include the following mandatory stages, each of which affects the final cost of the product:

1. Deep sorting and separation.The use of NIR (near infrared) optical scanners is mandatory to separate PE from PP, PVC and PET. Even 0.5% PVC impurity can lead to the release of hydrochloric acid during processing, causing corrosion of equipment and degradation of the entire batch of polyethylene. Modern lines use air separators with an accuracy of up to 98.5%, which is the minimum acceptable threshold for industrial applications.
2. Intensive washing and flotation.Removing adhesive labels, sand and organic residues requires a combination of hot water (at least 85°C), caustic soda and rotary dryers. The mistake of many operators is insufficient time for the material to remain in the frictor (friction). If the material has not undergone sufficient abrasive cleaning, microparticles of dirt remain on the surface of the granules, which become centers of crystallization and reduce the transparency of the final product.
3. Vacuum degassing and filtration.This is the most important step for restoring rheological properties. The melt must pass through filters with a fineness of at least 120 microns (for technical needs) or 40 microns (for food packaging) under pressure up to 350 bar. At the same time, the vacuum degassing system removes moisture and volatile substances. Lack of effective degassing leads to the appearance of pores in products during film extrusion or bottle blowing.
4. Stabilization and compounding.Recycled polyethylene always has a reduced melt index (MFI) due to chain degradation. To restore properties, it is necessary to introduce stabilizer packages (antioxidants, light stabilizers) and sometimes Virgin additives. Without this step, the material will become brittle after 6 months of outdoor use.
5. Quality control and certification.Each batch must be tested for melt flow, density and gel content. To enter the EU market, it is critical to have a certificate of compliance with Regulation (EU) No 10/2011 for materials in contact with food.

Each of these steps increases the cost per kilogram of granulate, but they are the ones that determine whether you can sell the product to premium brands or only to garbage bag manufacturers. Action: Audit your current line for vacuum degassing and multi-stage filtration systems - if not, an upgrade is inevitable.

Economic analysis of the secondary PE market in 2025–2026

The recycled polyethylene market has undergone radical changes over the past two years. If rPE was previously seen as a cheap alternative for low-grade products, then in 2026 the situation has changed. The introduction of the cross-border carbon tax (CBAM) in Europe and similar initiatives in the EAEU have made the use of virgin plastics made from petroleum significantly more expensive. According to industry association reports, the carbon footprint of recycled PE is 70-80% lower than that of virgin PE, which provides a direct tax advantage.

Price dynamics show an interesting correlation. In the first quarter of 2025, the price of quality PEHD granulate (bottle grade) reached 1,350 euros per tonne on FCA Europe terms, while the primary equivalent hovered around 1,280 euros. This price parity, and sometimes the superiority of the secondary market, is explained by the imbalance of supply and demand. Major corporations (Coca-Cola, Danone, Unilever) have committed to using at least 30–50% recycled plastic in their packaging by 2025. This guaranteed demand has created a shortage of quality raw materials.

HoweverCircular Economy in the PE Plastic Products Industrycarries with it the risks of volatility. Waste collection depends on seasonality and consumer activity. In winter, the collection of PET and PED bottles drops by 15–20%, which causes jumps in prices for raw materials for recyclers. Manufacturers operating under a just-in-time model without raw material inventories experienced line shutdowns of up to 2 weeks in January 2026. This led to fines from customers for failure to deliver.

The investment attractiveness of processing projects remains high, but the payback period has increased from 2.5 to 3.5 years due to the rising cost of equipment and energy. However, access to green finance and concessional loans for circular projects partially offsets these costs. Banks are increasingly requiring a sustainability strategy to approve loans to industrial enterprises.

Action: Review your long-term raw material supply contracts. Fixing volumes and prices with waste suppliers or concluding off-take agreements for the sale of finished granulate is now the only way to hedge the risks of price fluctuations.

Comparison of characteristics of primary and secondary PE

To make an informed purchasing decision, it is necessary to understand the technical differences between materials. Below is a comparison table of key parameters influencing the choice of material for various applications.

The table shows that blind replacement of primary plastic with secondary plastic without adapting the technological process is impossible. Process engineers have to recalculate casting or extrusion modes. For example, when switching to 50% rPEHD for canister production, we had to increase the dosing zone temperature by 15°C and reduce the screw speed by 10% to compensate for the change in melt viscosity.

Regulatory and Quality Standards

Work in the field of recycling is impossible without strict compliance with the regulatory framework. In 2026, the requirements became stricter both in the European Union and in the CIS countries. The key document for packaging manufacturers is EU Regulation No. 10/2011 on materials intended to come into contact with food. The use of recycled plastics for food requires EFSA (European Food Safety Authority) approval, which is only issued after the recycling technology has been assessed for its ability to remove potential contaminants.

In Russia and the EAEU countries, the main guideline is the Technical Regulations TR CU 005/2011 “On Packaging Safety”. However, the market is moving towards harmonization with international standards. More and more large retailers are requiring suppliers to have ISCC PLUS (International Sustainability and Carbon Certification) certificates. This standard confirms the origin of raw materials and the traceability of the entire supply chain - from waste bin to store shelf. The absence of such a certificate bars access to tenders of international corporations.

It is also important to take into account the GOST 15150 standard (for climate control) and the internal specifications of factories. Often the problem lies not in the material itself, but in the lack of passport data for the batch. We recommend implementing a digital product passport system, where each batch of granulate has a QR code with information about the percentage of recycled materials, production date and laboratory test results. This increases buyer confidence and simplifies auditing.

One of our partners was faced with a situation where customs detained a shipment of imported rPE due to a discrepancy between the HS codes and the lack of a declaration that the waste had undergone the necessary processing and was not hazardous. The downtime was 3 weeks, which led to losses. Lesson learned: customs clearance of secondary raw materials requires separate examination and correct classification of codes.

Action: Check that your certificates of conformity are current and that ISCC or equivalent documentation is available. If you are planning to export, start the audit procedure now, as it takes 3 to 6 months to obtain a certificate.

Practical application scenarios and implementation cases

The circular economy theory only works when it is implemented in specific production processes. Let's consider two real-life scenarios that demonstrate the effectiveness of the approach.

Scenario 1: Production of construction geomembranes and pipes

In this segment, aesthetics requirements are minimal, but durability and UV resistance are critical. A cable duct pipe plant has implemented a scheme to use 80% of its own production defects and 20% of post-consumer PEHD.

• Problem:The rise in prices for primary pipe composite (PE100) made the product uncompetitive in government procurement.
• Solution:Installation of an additional extruder to feed recycled materials into the middle layer of the pipe (multilayer coextrusion). The outer and inner layers (15% thickness each) were left from the virgin material to ensure smoothness and weldability.
• Result:Reducing the cost per linear meter of pipe by 22%. At the same time, the technical characteristics (ring stiffness) remained within the limits of GOST R 54475-2011. Savings amounted to more than 15 million rubles in the first year of operation.

The key point here is the use of multilayer technology. Trying to make the pipe 100% recycled would result in delamination when butt welding, which is unacceptable for pressure systems.

Scenario 2: Packaging for household chemicals and cosmetics

A manufacturer of shampoo bottles is faced with a requirement from a major customer to include 30% PCR (Post-Consumer Recycled) plastic in the bottle by 2025.

• Problem:The recycled material had an unstable color (gray spots) and odor, which is unacceptable for cosmetics.
• Solution:Introducing super purification technology using solid state polycondensation (SSP) to remove volatiles and then dyeing the material dark blue with a high pigment content masterbatch. The dark color effectively hides the inhomogeneities of the recycled materials.
• Result:Permission was obtained to use the material for non-food cosmetics. The customer retained the contract, and the manufacturer received a bonus for “sustainable development.” Costs increased by 8%, but margins remained high due to the premium positioning of the product.

This case shows thatCircular Economy in the PE Plastic Products Industryoften requires creative engineering solutions, such as changing the product design (color, shape) to adapt to the capabilities of recycled materials.

Integration of advanced heat transfer technologies into recycling processes

The successful implementation of circular economy projects is impossible without reliable energy and technological equipment. Washing, drying and especially extrusion processes require precise temperature control and efficient heat dissipation. This is where the quality of auxiliary equipment such as heat exchangers and cooling systems comes to the fore.

CompanyWuxi Kaisheng Electric Power and Petrochemical Equipment Co., Ltd.specializes in the development and production of high-tech solutions for such tasks. Their products, including titanium shell-and-tube heat exchangers and 316 stainless steel apparatus, play a critical role in ensuring the sustainability of plastic recycling lines. For example, when intensively washing PE waste, hot water supply (above 85°C) and subsequent rapid cooling of the material are required; The company's C46400 marine brass or copper-nickel corrugated tube bundles offer maximum thermal efficiency and resistance to harsh cleaning environments.

In addition, in the vacuum degassing and compounding processes described above, the melt temperature must be maintained with high precision. Air coolers and waste heat boilers from Wuxi Kaisheng, certified to ASME and PED standards, optimize energy consumption and reduce the carbon footprint of production, which directly affects the economic efficiency of the project. The use of N06625 nickel or titanium alloy components ensures long equipment life, even under the high pressure and temperature conditions found in modern extruders. The reliability of such solutions allows recycled granulate producers to avoid downtime and maintain high product quality that meets strict international standards.

Frequently Asked Questions

Can recycled polyethylene be used to produce food packaging?

Yes, it is possible, but only under strict conditions. The material must undergo a recycling process approved by regulatory authorities (for example, EFSA in Europe or Rospotrebnadzor in the Russian Federation), which ensures that all potential contaminants are removed to a safe level. Typically, bottle-to-bottle technology is used with deep vacuuming and filtration. You cannot simply wash out old canisters and make new ones for food - this is a violation of sanitary standards. Требуется сертификат соответствия для контакта с пищевыми продуктами.

Насколько прочнее изделия из первичного PE по сравнению с вторичным?

Разница в механической прочности составляет от 5% до 15% в зависимости от качества очистки и количества циклов переработки. Вторичный полимер имеет более короткую длину молекулярных цепей, что снижает ударную вязкость. Однако эту разницу можно нивелировать добавлением специальных модификаторов или увеличением толщины стенки изделия на 5–10%. Для большинства технических применений (трубы, ящики, пленка для стройматериалов) эта разница незаметна при правильной настройке оборудования.

Какой минимальный процент вторичного сырья считается экономически целесообразным?

Экономический эффект начинается при доле вторичного сырья от 20–30%. При меньшем проценте затраты на перенастройку оборудования и контроль качества могут не окупиться экономией на сырье. Оптимальным балансом для многих производителей в 2026 году является смесь 50/50 или 70/30 (вторичка/первичка), что позволяет сохранить стабильность процесса и существенно снизить углеродный след. Для изделий, не требующих высоких нагрузок (мусорные пакеты, ведра), доля может достигать 90–100%.

Что делать с неприятным запахом от вторичного гранулята?

Запах вызван остатками органики и летучими соединениями. Устранить его можно только на этапе экструзии с помощью эффективной системы дегазации (вакуумные насосы) и введения адсорбентов (например, цеолитов) в состав компаунда. Если запах остался в готовом грануляте, его можно попытаться переэкструдировать с продувкой инертным газом, но часто проще использовать такой материал для изделий, где запах не важен (геосетки, поддоны), или маскировать его сильными ароматизаторами, хотя последний метод не рекомендуется для закрытых помещений.
