2. rPC Overview: Polycarbonate Market Status and End-of-Life Vehicle PC Waste Source Analysis

Polycarbonate (PC) is a high-performance thermoplastic engineering plastic with excellent comprehensive properties, widely used in electronics and appliances, automotive manufacturing, construction panels, medical equipment, and optical media. Its high transparency, superior impact strength, and excellent heat resistance (Tg ~147ยฐC) make it difficult to replace in high-end application scenarios. However, traditional PC production relies heavily on the polymerization of bisphenol A (BPA) with phosgene or diphenyl carbonate, representing a high energy consumption and high carbon emission process. According to PlasticsEurope (2026) data, producing 1 ton of virgin PC generates approximately 6.2 tons of COโ‚‚ equivalent emissions.

2.1 Global Polycarbonate Consumption Pattern

In 2025, global PC consumption totaled approximately 5.6 million tons, with the Asia-Pacific region accounting for over 65%. China, with approximately 2.8 million tons of consumption, commands half of the global market. From an application perspective, automotive, electronics and appliances, and construction represent the three core consumption sectors.

2.2 End-of-Life Vehicle PC Waste: Core Growth Driver for rPC

The automotive industry is one of the fastest-growing sectors for PC consumption. With the acceleration of automotive lightweighting and electrification trends, the proportion of PC applications in components such as headlight lenses, panoramic sunroofs, instrument panel skeletons, and charging station housings continues to increase. A traditional fuel vehicle contains an average of 15-25 kg of PC, while a pure battery electric vehicle (BEV) can contain 30-45 kg of PC (primarily from battery pack housings, charging interfaces, and lightweight structural components).

End-of-Life Vehicles (ELV) represent the most scalable potential waste source for rPC. According to EU ELV regulations (2023 revised version), by 2030, the recycling rate for plastics in end-of-life vehicles must reach 30%, with at least 25% achieving closed-loop recycling (same-grade reuse or upcycling; downcycling does not count). China's "Automotive Product Producer Responsibility Extension Pilot Implementation Plan" (2022) also explicitly states that by 2025, the material recovery rate for end-of-life vehicles must reach 95%, with plastic recovery utilization rate of no less than 30%.

*Data sources: European Automobile Manufacturers Association (ACEA), 2025; Topcentralยฎ Technical Center Waste Analysis Report, 2026*

The collection and sorting of end-of-life vehicle PC waste faces significant challenges. Currently, approximately 40% of PC waste in Europe is recovered through automotive dismantling enterprises, while the remaining 60% enters "Automotive Shredder Residue" (ASR), ultimately going to incineration or landfillโ€”which is technically classified as treatment rather than recycling. Improving the separation accuracy and recovery rate of PC waste is a prerequisite for rPC industry scaling.

2.3 Other Sources of PC Waste

Beyond end-of-life vehicles, Waste Electrical and Electronic Equipment (WEEE) is also an important source of rPC. In particular, post-consumer computer housings, printer housings, and phone cases contain large quantities of flame-retardant PC/ABS alloys. PC sunlight panels from demolished buildings and disposable dialysis housings from the medical sector also possess recycling value. However, the waste quality, contamination levels, and recycling economics vary significantly across sources, requiring targeted sorting and pretreatment processes.

3. Physical Recycling Technology Pathway: PlasCirclesโ„ข๏ธ Process Details

Physical recycling (mechanical recycling) is the most mature and widely applied technology pathway in the rPC industry. Its core principle is to transform PC waste into pellets suitable for injection molding or extrusion through physical means without altering the chemical molecular structure of PC. Topcentralยฎ's core brand PlasCirclesโ„ข๏ธ has deeply cultivated this field, establishing a full-chain standardized process from waste inbound to high-quality pellet outbound.

3.1 PlasCirclesโ„ข๏ธ Standardized Process Flow

PlasCirclesโ„ข๏ธ's physical recycling process follows a four-stage core flow: "crushing โ†’ cleaning โ†’ sorting โ†’ melt pelleting," with each stage containing several critical subprocesses to ensure the purity, performance consistency, and processing stability of the final rPC pellets.

3.2 Quality Control and Performance Parameters

The core competitive advantage of the PlasCirclesโ„ข๏ธ system lies in its quality consistency control. Through online Near-Infrared (NIR) detection, Melt Flow Rate (MFR) real-time monitoring, and batch traceability systems, every batch of rPC pellets meets downstream customer requirements.

*Data sources: Topcentralยฎ Quality Control Laboratory, 2026; SGS Test Report, 2025*

3.3 Physical Recycling Limitations and Improvement Directions

Despite mature physical recycling technology, its inherent limitations cannot be ignored: each melt processing causes slight degradation of PC molecular chains (thermal degradation, hydrolysis), manifested as increased MFR and decreased impact strength. Typically, PC can withstand 2-3 physical recycling cycles without significant performance decay. To address this challenge, PlasCirclesโ„ข๏ธ has developed reactive compatibilization technologyโ€”adding trace chain extenders (such as epoxy-functionalized polymers) during the melt extrusion stage to repair partially broken molecular chains through end-capping reactions, improving rPC impact strength retention from 85% to over 92%. This technology achieved industrial application in 2025.

4. Chemical Recycling Technology Pathway: Depolymerization โ†’ Monomer โ†’ Repolymerization Full Chain Analysis

Chemical recycling is an important complement to physical recycling, particularly suitable for processing low-quality, highly contaminated PC waste or waste containing complex additives that physical recycling cannot effectively handle. Its core principle is to completely depolymerize PC macromolecular chains into monomers (bisphenol A, BPA) through chemical reactions, then purify and repolymerize into virgin-quality PC resin.

4.1 PC Chemical Recycling Mainstream Process Pathways

Chemical recycling of PC is primarily based on the hydrolyzability of polycarbonate bonds (-O-CO-O-). Depending on the reaction medium, it can be divided into three categories: hydrolysis, alcoholysis, and aminolysis, with methanol alcoholysis currently being the most industrialized pathway.

4.2 From Waste to New PC: Full Chain Analysis

Taking methanol alcoholysis as an example, the complete chemical recycling chain includes five stages: pretreatment โ†’ depolymerization โ†’ separation and purification โ†’ monomer refinement โ†’ repolymerization.

1. Pretreatment: Similar to physical recycling, PC waste requires crushing, cleaning, and sorting to remove metals, non-PC plastics (such as PP, PE, ABS), and contaminants. Chemical recycling has relatively lower requirements for feed purity (PC content โ‰ฅ85%), but heavy metal and flame retardant content must be strictly controlled to avoid affecting subsequent catalytic reactions and monomer quality.

2. Depolymerization Reaction: Pretreated PC fragments and methanol are added to a high-pressure reactor in proportion (typically 1:4 to 1:8). Under catalyst (such as sodium methoxide, zinc oxide) at 250-300ยฐC, 8-12 MPa for 30-90 minutes, carbonate bonds in PC molecular chains break, generating bisphenol A (BPA) and dimethyl carbonate (DMC).

3. Separation and Purification: After cooling and depressurizing the reaction mixture, excess methanol is recovered through distillation (recycled). The remaining mixture undergoes liquid-liquid extraction or crystallization separation to obtain crude BPA (purity ~92-95%) and DMC (purity ~98%).

4. Monomer Refinement: Crude BPA requires multi-stage distillation, recrystallization, or adsorption decolorization to raise purity to above 99.9% (polymerization grade), removing residual catalysts, color bodies, and by-products (such as isomers). This step is one of the highest-cost stages in chemical recycling.

5. Repolymerization: Refined BPA reacts with fresh DMC or phosgene using the same melt ester exchange or interfacial polycondensation process as virgin PC production to produce PC resin indistinguishable from virgin quality.

4.3 Economics and Environmental Benefits of Chemical Recycling

The core advantage of chemical recycling lies in its "infiniteๅพช็Žฏ" capability: theoretically, PC can be repeatedly depolymerized and repolymerized without quality loss. However, its high capital expenditure and operating costs are the main barriers to large-scale application. According to McKinsey (2026) estimates, the production cost of chemically recycled rPC (โ‚ฌ600-1,000/ton) is 1.5-3 times that of physically recycled rPC (โ‚ฌ200-400/ton), even higher than virgin PC (โ‚ฌ400-600/ton). Therefore, chemical recycling is more suitable for high-value, high-quality requirement closed-loop applications (such as medical-grade, optical-grade PC) or complex waste that physical recycling cannot handle (such as glass fiber-reinforced, flame-retardant PC/ABS alloys).

From a carbon emission reduction perspective, the carbon footprint of chemically recycled rPC is approximately 45-55% of virgin PC, lower than the 8-30% of physical recycling, but higher than the 5-15% of solvent-based recycling (see Section 5). Its carbon emissions mainly come from energy consumption during high-temperature/high-pressure reactions and purification processes.

5. SolvenTieRโ„ข๏ธ Solvent-Based Recycling: Selective Dissolution Process

Solvent-based recycling is a physical-chemical hybrid technology between physical and chemical recycling. Its core principle leverages the selective solubility of PC in specific solvents to extract PC from waste mixtures, then separate through anti-solvent precipitation or evaporation to obtain high-purity PC resin. Solvent-based recycling does not involve breaking and repolymerizing PC molecular chains, therefore it belongs to the physical separation process, not chemical recycling.

5.1 SolvenTieRโ„ข๏ธ Process Principles

SolvenTieRโ„ข๏ธ is a solvent-based recycling technology brand jointly developed by Topcentralยฎ's R&D Center and the Polymer Department of Zhejiang University. This process adopts a three-stage flow: selective dissolution โ†’ separation โ†’ purification, with the core solvent being an optimized mixed solvent system (primarily ฮณ-butyrolactone/toluene blend, volume ratio 7:3).

5.2 Process Parameters and Product Quality

The core advantage of the SolvenTieRโ„ข๏ธ process lies in low-temperature operation (60-80ยฐC vs. 240-280ยฐC for physical recycling), avoiding PC thermal degradation and enabling rPC performance retention close to 100%. Simultaneously, this process effectively removes surface contaminants such as coatings, inks, and adhesives that are difficult to handle through physical recycling.

5.3 Solvent-Based Recycling Positioning and Prospects

Solvent-based recycling is technically positioned between physical and chemical recycling: it can handle more complex waste than physical recycling (such as coated, plated headlight waste) with higher product quality; it has lower investment and operating costs than chemical recycling (no high-pressure reactors or complex purification systems needed) and does not produce monomers. However, solvent-based recycling's energy consumption mainly comes from the solvent distillation recovery stage, and if solvent recovery efficiency is insufficient, economic and environmental benefits will significantly decline.

Currently, the SolvenTieRโ„ข๏ธ process has completed laboratory-scale validation, with plans to explore constructing the first pilot/production line with partners in the future. Its target market is high-quality transparent rPC (such as automotive headlights, optical lenses), which can replace virgin PC in scenarios with stringent performance requirements.

6. Global rPC Market Pattern: Capacity Distribution, Competition Pattern and Major Manufacturers

6.1 Global rPC Capacity and Regional Distribution

As of end of 2025, global annual rPC (physical recycling) capacity is approximately 520,000 tons, with actual production of approximately 380,000 tons (capacity utilization rate 73%). Capacity is highly concentrated in the Asia-Pacific and European regions, together accounting for 82% of global total capacity.

*Data sources: MarketIntell Global rPC Market Report, 2026; China Waste Plastics Association, 2026*

China is the world's largest rPC producer and consumer. In 2025, China's rPC production was 145,000 tons, accounting for 38% of global production. However, China's rPC industry is still dominated by small and medium enterprises, with products mainly concentrated in low-end universal grades (black, mixed colors). High-quality transparent grade and flame-retardant grade rPC still largely rely on imports.

6.2 Major Global rPC Manufacturers

The global rPC market is dominated by a few large chemical companies and specialized recycled plastics companies. Among them, Covestro and Trinseo represent physical recycling and chemical recycling pathways; Toray and Teijin focus on automotive closed-loop recycling; Topcentralยฎ PlasCirclesโ„ข๏ธ is a leading brand in China's physical recycling sector.

6.3 Competition Pattern and Market Trends

The current rPC market presents a bipolar pattern: large chemical companies (Covestro, Trinseo) leverage virgin PC technology accumulation and brand premium to focus on high-end closed-loop markets (such as automotive OEM designated recycled materials); specialized recycling companies (Topcentralยฎ, MBA Polymers) dominate the mid-to-low-end universal market through cost advantages and flexible supply.

Over the next five years, with theๆŽจ่ฟ› of EU ELV regulations (2030 targets) and China's "15th Five-Year Plan" circular economy planning, the automotive sector will become the fastest-growing rPC demand track. It is estimated that by 2030, the global rPC market size will reach $7.2 billion, with automotive applications increasing from 32% of the 2025 share to 45%.

7. Policy and Regulation Drivers: EU ELV, China's 15th Five-Year Plan and CBAM Impact on rPC Industry

7.1 EU ELV Regulations: Catalyst for Mandatory Closed-Loop Recycling

The 2023 revision of the EU End-of-Life Vehicles Directive (2000/53/EC) is one of the most influential regulations on the global rPC industry. Key plastic recycling-related provisions include:

  • Recycling rate targets: By 2030, the recycling rate for plastics in end-of-life vehicles must reach 30%, with at least 25% achieving "closed-loop recycling" (same-grade reuse or upcycling; downcycling does not count).
  • Mandatory recycled content requirements: From 2030, plastic components in new vehicles must contain no less than 25% recycled content (by mass), with PC components containing no less than 20% recycled content.
  • Design for recyclability: From 2027, new vehicle designs must ensure that over 95% of plastic components are recyclable, and composite structures that impede recycling (such as non-peelable metal plating, multi-layer co-injection molding) are prohibited.

7.2 China's 15th Five-Year Plan Circular Economy: Domestic Driving Force for rPC

China's "15th Five-Year Plan" (2026-2030) lists "circular economy contributing to carbon reduction actions" as a key project, with plastic pollution control and recycled material promotion as core content. Policies directly related to rPC include:

  • Recycled material product promotion: By 2028, the recycled plastics usage proportion in electronics and appliances, automotive, and packaging sectors must reach no less than 20% (by mass).
  • Waste plastics recycling system upgrade: Build 50 city-level waste plastics sorting centers, promote high-value recycling of engineering plastics from end-of-life vehicles and electronic waste.
  • Carbon footprint accounting and certification: Establish recycled plastics carbon footprint accounting standards, provide carbon quota incentives to enterprises using recycled plastics.
  • Extended Producer Responsibility (EPR): Expand EPR system coverage, requiring electrical and electronic and automotive production enterprises to bear recycling and disposal costs for post-consumer products.

7.3 CBAM and Carbon Tariff: rPC Cost Competitiveness

The EU Carbon Border Adjustment Mechanism (CBAM, or "carbon tariff") entered its transition period in October 2023 and officially takes effect in January 2026. Although CBAM's first batch of covered products is steel, aluminum, cement, fertilizers, electricity, and hydrogen, the EU has explicitly stated it will expand to plastics and plastic products before 2030.

For the PC industry, CBAM's impact is profound: the carbon footprint of virgin PC (6.2 tons COโ‚‚/ton) is much higher than steel (1.8 tons COโ‚‚/ton) and aluminum (4.5 tons COโ‚‚/ton). Once covered by CBAM, China's exports of virgin PC to the EU will face approximately โ‚ฌ200-300/ton in carbon tariffs (calculated at โ‚ฌ50/ton COโ‚‚). The carbon footprint of physically recycled rPC (0.5-1.9 tons COโ‚‚/ton) is only 8-30% of virgin PC, reducing carbon tariff costs by 70-92%.

7.4 Various Countries' Regulations on rPC Market Demand Pull Data

Globally, major economies' regulations on recycled plastics are shifting from "encouraging" to "mandatory." Japan's "Plastic Resource Recycling Promotion Act" (implemented 2022) requires PET bottle recycled content to reach 60% by 2030, indirectly promoting standardized development of the entire recycled plastics market. US California's AB 793 requires plastic packaging recycled content to reach 50% by 2030, while federal-level "Ocean Pollution Prevention Act" is also advancing.

Domestically, China's Ministry of Ecology and Environment's "Detailed Rules for the Implementation of End-of-Life Vehicle Recovery Management" (2023 revision) explicitly encourages end-of-life vehicle dismantling enterprises toๅฎšๅ‘้”€ๅ”ฎ high-value PC/ABS engineering plastic components to qualified recycling enterprises, opening the complete chain from end-of-life vehicle recovery to rPC raw materials. This policy directly benefits enterprises like PlasCirclesโ„ข๏ธ specializing in end-of-life vehicle PC recycling.

8. DPP Digital Product Passport Application in rPC Supply Chain

8.1 DPP Concept and Policy Background

The Digital Product Passport (DPP) is a core tool proposed by the EU Ecodesign for Sustainable Products Regulation (ESPR, 2024/1781), requiring all products under regulatory scope (including plastics, batteries, textiles, electronics and appliances, etc.) to be equipped with DPPs before 2030. A DPP is essentially a data carrier based on blockchain and Internet of Things technology, storing product full lifecycle information including raw material sources, manufacturing processes, carbon footprints, recyclability, and repair guidelines.

For the rPC industry, DPP is not only a regulatory compliance requirement but also a value proof tool: through DPP, rPC suppliers can transparently and credibly display waste sources, recycling processes, carbon reduction data, and performance indicators to downstream customers, thereby establishing a trust premium.

8.2 rPC-DPP Data Architecture

PlasCirclesโ„ข๏ธ's DPP system is designed based on the GS1 standard framework, containing four core data modules:

1. Identity and Traceability Module: Records the unique identifier (EID+UUID) for each batch of rPC, including waste source (e.g., headlight lenses from end-of-life vehicles of a specific model), recycling batch number, production time, and production line number. 2. Process and Quality Module: Records the recycling process route (physical/chemical/solvent-based), key process parameters (temperature, pressure, residence time), and quality inspection data (MFR, impact strength, ash content, etc.). 3. Environmental Footprint Module: Provides third-party certified LCA data (carbon footprint, water consumption, energy consumption), carbon reduction certification (compared to virgin PC), and CBAM compliance information. 4. Circularity Module: Records the recyclability of the rPC product itself (number of physical recycling cycles possible), recommended recycling treatment methods, and "designed for recyclability" certification.

8.3 DPP Evidence Package and Blockchain Attestation

To ensure DPP data immutability and traceability, PlasCirclesโ„ข๏ธ adopts a three-level evidence package mechanism of EID+UUID+SHA256 hash:

  • EID (Enterprise Identity Identifier): Topcentralยฎ's unique enterprise code in the Ministry of Industry and Information Technology's Industrial Internet Identification Resolution System (EID-A1-XXXXXXXX-001), used to identify enterprise identity and product source.
  • UUID (Universal Unique Identifier): The unique batch ID for each batch of rPC pellets, formatted as an 8-4-4-4-12 hexadecimal string, associated with all production data for that batch.
  • SHA256 Hash: The batch production data (including process parameters, quality inspection reports, LCA data) is packaged and its SHA256 hash computed, then on-chain attested on the "XinghuoยทChain Network" blockchain infrastructure. Downstream customers can scan the QR code on rPC packaging to obtain the hash value and compare it with on-chain attestation to verify data authenticity.

9. China rPC Industry Challenges and Opportunities

9.1 Core Challenges

Although China's rPC industry has formed a certain scale, the structural challenges it faces cannot be ignored:

1. Incomplete waste recycling system: China's end-of-life vehicle recycling rate is less than 40% (2025 data), with large quantities of PC waste mixed into construction waste or low-value plastics, entering incineration or landfill. Weak front-end sorting capability for waste leads to unstable supply of high-quality PC waste.

2. High-end rPC quality stability needs improvement: Automotive OEMs have extremely stringent requirements for rPC key indicators such as impact strength (Izod Impact Strength), heat deflection temperature (HDT), and weather resistance. Some domestic enterprises' product performance variation between batches is still within ยฑ15%, while foreign competitors can control it within ยฑ5%. Closing this gap requires continuous formula optimization and process control investment.

3. Long certification cycles, high market entry barriers: IATF 16949 automotive quality management system certification typically takes 18-24 months from initiation to certification, and GRS certification also requires 6-12 months. For small and medium rPC enterprises, certification costs and time investment constitute significant entry barriers.

4. Chemical recycling technology impacting physical recycling market: Chemical recycling technology represented by polycarbonate chemical depolymerization is developing rapidly. Its product purity advantage (ๅฏ่พพ99.5%ไปฅไธŠ) and tolerance for mixed PC waste is higher than physical recycling, potentially exerting price pressure on mid-to-low-end physical recycling rPC market within the next 5-8 years.

9.2 Major Opportunities

The other side of challenges presents significant opportunity windows. Mandatory requirements from policies and regulations are creating deterministic market demand growth. Full implementation of EU ELV directives in 2025, plus CBAM's cost penalties on high-carbon-emission imported products, will significantly boost European market demand for China's rPC. Simultaneously, the explosive growth of China's new energy vehicles (over 12 million units produced and sold in 2024) provides a huge incremental market for rPCโ€”new energy vehicles have higher demand intensity for lightweight, high-temperature-resistant PC materials than traditional fuel vehicles.

Technological progress is also lowering rPC cost barriers. For example, AI-driven Near-Infrared Spectroscopy sorting technology improves sorting speed and accuracy 5-8x compared to traditional manual sorting, effectively reducing front-end sorting costs by 15%-20%. Topcentralยฎ has deployed third-generation AI sorting equipment at its Ningbo factory, achieving 96.8% accuracy in PC purity sorting from raw materials.

A.2 EID Traceability Coding System Design

Topcentralยฎ's EID traceability coding follows ISO/TC 323 technical specifications, combined with internal enterprise coding practices. The EID coding structure is as follows:

EID-8-digit enterprise code-4-digit batch code-3-digit serial code

  • 8-digit enterprise code (fixed value: 8F2A1B3C): Assigned and registered by Topcentralยฎ at the China Electronics Standardization Institute (CESI), ensuring global uniqueness.
  • 4-digit batch code (e.g., JF07): Represents the production month and batch number. JF represents July 2026 (June July August... actual mapping: F=6), 07 represents the 7th production batch.
  • 3-digit serial code (001-999): Represents the serial number within that batch, starting from 001 and incrementing.
The EID code corresponds to the product barcode through GS1 Global Trade Item Number (GTIN-14), supporting global supply chain scanning identification. Customers can directly access PlasCirclesโ„ข๏ธ TraceBytesโ„ข๏ธ DPP cards by scanning with a phone or entering the EID code on the webpage to view complete batch production data, carbon footprint reports, and third-party verification statements.

A.3 SHA-256 Hash Attestation and Tamper-Proof Mechanism

SHA-256 (Secure Hash Algorithm 256-bit) is a secure hash algorithm designed by the US National Security Agency (NSA), with output length of 256 bits (64-character hexadecimal string). Topcentralยฎ's DPP system generates SHA-256 hashes for each batch of PlasCirclesโ„ข๏ธ rPC's original production data (including purchase invoices, NIR sorting reports, melt pelleting process parameters, quality inspection reports, and shipping lists), and synchronously stores the hash values on the CESI blockchain attestation platform and Alibaba Cloud OSS object storage.

When customers question DPP data authenticity, they can upload original data files through the DPP verificationๅ…ฅๅฃ on Topcentralยฎ's official website (https://www.topcentral.vip/dpp-verify/). The system will calculate the SHA-256 hash in real-time and compare it with archived records to achieve second-level authenticity verification.

SHA-256 hash has irreversibility: given a hash value, the original data cannot be reverse-engineered, but given original data, the hash value can be quickly verified for matching. This feature ensures DPP data integrity and non-repudiation.

A.4 Three-Source Cross-Verification Mechanism

The data sources in Topcentralยฎ's DPP Evidence Package follow the "three-source cross-verification" principle, meaning each key data item (recycled material content, carbon footprint, waste source) requires at least two independent sources for cross-checking, minimizing the risk of data fabrication.

Three-Source Verification Matrix Example

> DPP Evidence Package data attestation complies with EU GDPR data protection requirements. Non-sensitive business data (such as waste source location, carbon footprint values) is externally displayed, while sensitive personal information (such as supplier contacts) is encrypted and stored in Alibaba Cloud OSS private buckets, not externally disclosed.

Frequently Asked Questions (FAQ)

Q1: How much performance gap exists between recycled polycarbonate (rPC) and virgin PC?

A: Through reactive compatibilization technology (such as chain extender addition), PlasCirclesโ„ข๏ธ rPC's impact strength retention can reach over 92%, with tensile strength and flexural modulus close to virgin PC levels. It can directly replace virgin PC in most application scenarios, particularly suitable for automotive components and electronics and appliances housings.

Q2: Which is more suitable for enterprises with strict carbon reduction requirementsโ€”chemically recycled rPC or physically recycled rPC?

A: Physically recycled rPC has the lowest carbon footprint (70-92% reduction compared to virgin PC) and lower production costs (โ‚ฌ200-400/ton), suitable for most general applications. Chemically recycled rPC has a relatively higher carbon footprint but can achieve "infinite cycling" (molecular-level regeneration), suitable for high-quality closed-loop applications such as optical-grade and medical-grade.

Q3: What are the main regulatory barriers for rPC exported to the EU?

A: Starting in 2026, EU ELV directives require automotive recycled plastic content compliance, PPWR sets recycled content targets (25% by 2030), and CBAM's carbon price transmission effect is significant although it does not yet directly cover plastics.
