1 概述
1.1 什么是再生PP
再生聚丙烯（rPP，Recycled Polypropylene）是以聚丙烯废塑料为原料，经分选、破碎、清洗、熔融过滤、造粒等工序重新加工得到的颗粒料，以物理回收为主。按废料来源可分为两类：工业回收料（PIR）——注塑水口料、薄膜/编织袋边角料、无纺布边角料、汽车件废料等，纯度高、批次稳定；消费后回收料（PCR）——洗衣液瓶、外卖餐盒、家电拆解件、报废汽车件等，需深度清洗与分选。
1.2 核心价值
一是减排：相比原生PP，每吨再生PP约减排67%～80%碳排放；二是成本：2025年注塑级再生PP出厂均价约8240～8720元/吨（不同统计口径），低于原生料；三是政策驱动：中国新能源汽车再生PP使用比例要求、欧盟ELV法规再生含量要求、欧盟PPWR包装再生含量要求均在加码，需求长期向上。

1 Overview
1.1 What is Recycled PP
Recycled polypropylene (rPP, Recycled Polypropylene) is pellet material obtained by reprocessing polypropylene waste plastics through procedures such as sorting, shredding, washing, melt filtering, and pelletizing, mainly through physical recycling. According to the source of the waste, it can be divided into two categories: Industrial Recycled Material (PIR) — injection molding sprues, film/woven bag scraps, non-woven fabric offcuts, automotive part waste, etc., which are high in purity and have stable batches; Post-Consumer Recycled Material (PCR) — laundry detergent bottles, takeout food containers, dismantled home appliances, scrapped automotive parts, etc., which require deep cleaning and sorting.
1.2 Core Values
First, emission reduction: compared to virgin PP, each ton of recycled PP reduces carbon emissions by about 67% to 80%; second, cost: in 2025, the ex-factory average price of injection molding grade recycled PP is about 8,240 to 8,720 RMB per ton (depending on different statistical standards), lower than virgin materials; third, policy-driven: requirements for the use of recycled PP in China's new energy vehicles, the recycled content requirements in the EU ELV regulations, and the EU PPWR packaging recycled content requirements are all increasing, and demand is expected to rise in the long term.

Table 5 Overview of Recycled PP Grade System
| Hierarchical Dimension | Specific level | Explanation |
|---|
| By recycling source | PIR Industrial Recycled Material | Injection molding runner material, film/woven bag scraps, non-woven fabric scraps, automotive part waste — high purity, consistent batches |
| By source of recycling | Post-consumer recycled (PCR) material | Laundry detergent bottles, takeout food containers, disassembled home appliances, scrapped car parts — require deep cleaning and sorting |
| Named according to national standards | GB/T 40006.1/3-2021 | Five-character group, e.g.: PP(REC)-G1-C-1, M, 160-91 = gray · cylindrical · industrial source, injection molding grade, MFR 18, density 0.91 |
| By industry level | First-grade material / Second-grade material / Third-grade material | First grade: ash content ≤1%, white/natural color, can replace virgin material; Second grade: ash content ≤3%, mixed colors; Third grade: ash content ≤10%, low-end dark-colored products |
| By industry level | Grade A / Grade B / Grade C | Grade A high-end alternative (MFR fluctuation ≤ ±8%, ash content ≤ 0.05%, black spots ≤ 3 per 100g); Grade B blended enhancement; Grade C functional filling |
| By processing use | Injection molding grade / Drawing grade / Blow molding grade / Extrusion grade / Fiber non-woven fabric grade / Coating grade | The key is to look at the melt index range, see Table 7 in Chapter 4 for details. |
| According to the recipe | General-purpose / Enhanced / Modified | Enhancements: glass fiber, talc, calcium carbonate; Modifications: toughening (POE/EPDM), flame retardant, weather resistant, UV resistant |

6 Market and Trend Overview
The following data comes from third-party industry reports for 2024–2026, with significant differences in statistical scope (physical pellet output vs. total scope, recycled black PP vs. all recycled PP). When citing, be sure to specify the scope.
Production scale (various calibers): In 2025, China's production of recycled PP physical pellets is about 2.14 million tons (according to the China Plastics Processing Industry Association / Material Recycling Association, a year-on-year increase of 7.35%); there is also a full-caliber estimate of about 4 million tons. Recycled PP accounts for about 7% to 28% of total PP consumption (large differences due to caliber).
Application structure (2024 PP recycled black material caliber): Automobiles about 380,000 tons, home appliances about 420,000 tons, logistics and municipal totaling over 700,000 tons; PP recycled black material accounts for about 18.7% of the total recycled plastic production, making it the second largest recycled category after PET.
Automobiles (strongest growth point): In 2025, the consumption of recycled PP for vehicles will be 387,000 tons (up 21.3% year-on-year), and it is expected to reach 459,000 tons in 2026; for 12 types of non-load-bearing structural parts in new energy passenger vehicles, the usage ratio of recycled PP will be ≥15% (8% in 2024); automotive-grade thresholds: ash content ≤0.35%, MFR fluctuation ±1.2, tensile strength retention ≥92.5% (GB/T 44362-2025). The amount of recycled PP per vehicle for Nio ET5, Li Auto L7, XPeng G6, etc., is about 14.3 kg.
EU regulations (driven by external demand): According to the new ELV regulations, from 2032 onwards, new car models must have ≥15% recycled plastics, and by 2036 ≥25%, with at least 20% coming from the closed loop of end-of-life vehicles; the EU PPWR requires that by 2030, non-PET packaging in contact with sensitive substances must have ≥10% recycled content.
Food-grade progress: By 2025, China is expected to have about 37 companies with certification qualifications for food contact grade recycled PP (concentrated in East and South China); in the EU, governed by (EU) 2022/1616, EFSA certified processes are required.
High value-added proportion: About 28% of China's recycled PP is used in high value-added fields such as automotive and electronics, compared with about 43% in the EU, indicating significant room for structural upgrading.
