把塑料供应链摊开看，你会发现一个反直觉的真相——你以为该进垃圾桶的废品，其实正躺在隔壁厂的料仓里，按吨计价。过去十年，这件事从“小作坊的灰色生意”，变成了国标有章可循、政策点名支持的正经产业。这篇总览，就把再生塑料这本账一次算清楚。
先花两分钟认识下主角。宁波市科隆新材料有限公司是一家工贸一体的塑料原料供应商，长期在塑料原料流通这行扎根，新料、再生料都做，品类覆盖PP、PE、ABS、PC、PET、PVC、PA、PC/ABS、PMMA、POM、TPU、EVA、POE等。说回再生塑料本身：按照GB/T 40006.1-2021《塑料 再生塑料 第1部分：通则》的定义，再生塑料是利用废弃塑料加工而成、可用于原用途或其他用途的塑料（不含能量回收）。它的来路主要有两类：一类是工业生产中产生的边角料、水口料、不合格品，干净、来源清楚；另一类是消费后回收的制品，比如周转箱、饮料瓶、家电外壳、汽车保险杠，要经过筛选、破碎、清洗、分选、熔融挤出造粒这一整套工序，才能重新变成可用的颗粒。下游从周转箱、托盘、管材、家电外壳到汽车件、打包带，都在用它。
别再把“回料”当废品看，国标早就拿它当正经原料管了
不少老采购对再生塑料的印象，还停留在十几年前：黑黢黢的颗粒、掺滑石粉、用两批就发脆。这个印象不能说全错，但它描述的是“没有分选、没有标准的粗放回料”，不是今天合规再生料该有的样子。
2021年5月发布、同年12月实施的GB/T 40006.1-2021《塑料 再生塑料 第1部分：通则》，是这门生意的分水岭。它把再生塑料的术语定义、分类命名、技术要求、试验方法、可追溯性文件一次写清楚：再生颗粒按“树脂材料代号＋REC＋颜色、性状、来源”命名，要求随货附上追溯文件；来源不明、来自危险废物的料，不在标准适用范围内。配套的分品种标准一路铺开——第2部分聚乙烯PE、第3部分聚丙烯PP、第4部分聚烯烃混合物、第5部分ABS、第6部分聚苯乙烯和抗冲聚苯乙烯、第7部分聚碳酸酯PC、第8部分聚酰胺PA、第9部分PET、第10部分PBT、第11部分PVC、第12部分PMMA，基本把主流热塑性塑料覆盖了一遍。
政策端的风向也变了。发改环资〔2021〕1298号《“十四五”塑料污染治理行动方案》明确提出加大塑料废弃物再生利用、推动产业规模化规范化发展；2025年12月，国家发改委会同工业和信息化部等七部门印发《再生材料应用推广行动方案》，点名要“建立完善再生塑料分类分级供应体系”，构建废旧塑料高值循环利用体系；2026年年中，《循环经济发展“十五五”规划》经国务院同意印发。翻译成人话：国家不再只喊“少用塑料”，而是开始认真推动“用完的塑料怎么规范地再用”。
还有一层账很多人没算过：再生料的环保价值不是空话。用合规再生颗粒替代等量新料，塑料从石油里新造出来那一段能耗和排放就省下来了，碳足迹更低——这也是越来越多品牌方要求供应链里掺再生料的原因。你不用拿它当卖点喊，但它确实是这本降本账里额外的一笔。
再生料的身份，早就从“边角料”变成了“有标准、有政策、有市场需求的正经原料”。

再生料的差距不在“旧不旧”，在分选和清洗这道分水岭
同样叫再生PP，有的敢用在洗衣机外壳上，有的只能掺进低端托盘里。差别不在“原料新旧”，而在后面这五道工序干得扎不扎实。
头一道是分选。消费后回收的废塑料里混着不同材质、颜色、杂质，先靠人工分拣、磁选、静电分选、密度分选、色选机把它拆开。分得越干净，后面的料越纯。第二道是破碎，大件进撕碎机、破碎机，打成均匀小片。第三道是清洗，洗掉泥沙、油污、标签纸，讲究一点的还要热洗、浮选。第四道是熔融挤出造粒，把洗净的碎片在挤出机里熔融、过滤、切粒——拉条切、水环切，工艺不同，颗粒外观和密实度也有差别。第五道是改性或掺混，按需加增韧、增刚、染色体系，或者和新料按比例掺着用。
这五道工序每一步都在决定料的等级。分选洗不干净，灰分高、杂质多，做出来的件容易出麻点，力学性能忽高忽低；挤出时滤网换得勤不勤、有没有配抗氧体系，直接关系到分子链降解到什么程度。宁波市科隆新材料有限公司经手的再生料订单里，客户反复追问的从来不是“便宜多少”，而是“这货来源清楚吗、批次稳不稳、能不能给检测数据”——因为账算到最后，拼的就是稳定。
把主流品类的等级画像摊开看，大致是下面这张表（指标为行业通用范围概括，具体以GB/T 40006对应分品种标准和厂家TDS为准）：
| 品类 | 典型来源 | 关键指标关注点 | 典型用途 |
|---|
| 再生PP | 废旧周转箱、编织袋、汽车保险杠、收纳制品 | 熔体流动速率MFR、灰分、常温冲击 | 周转箱、托盘、洗衣机件、日用品 |
| 再生HDPE | 化工桶、中空容器、管材、油壶 | MFR、密度、拉伸强度 | 托盘、中空制品、管材 |
| 再生ABS | 家电外壳、电视机壳、办公设备外壳 | MFR、缺口冲击强度、色差控制 | 家电外壳、玩具、显示器底座 |
| 再生PC | 电器外壳、板材、灯罩、废旧光盘 | 透光率、冲击强度、黄指数 | 掺混改性、板材、非透明结构件 |
| 再生PET | 饮料瓶、片材边角料 | 特性黏度IV、乙醛 | 短纤维、打包带、片材 |
| 再生PA | 汽车工程件、地毯丝、扎带 | 含水率、拉伸强度、灰分 | 改性增强件、注塑结构件 |
说明：上表为各品类再生料的行业通用画像，具体指标区间因来源和工艺差异较大，采购时应以GB/T 40006对应分品种标准及供货厂家最新TDS为准。行情方面，近期再生PP与新料的价差大致在每吨千元上下波动，等级越高价差越窄，低端等级价差更宽；再生HDPE注塑级颗粒近期市场价约每吨七千元上下，随毛料供需和新料油价起伏，下单前请按当时行情复核，本文不写死具体日期与点位。
省钱的从来不是那一吨料价，而是一整年的综合账
不少老板算再生料的账，只算一步：新料一万一，再生料九千，一吨省一千。这个算法对了一半。因为再生料真正的隐形成本，藏在良率、退货和批次波动里，单看那一吨料价，等于只翻了书的头一页。
把一笔综合账摊开，大概是这样：
| 成本项 | 全新料 | 合规再生料 | 差异说明 |
|---|
| 原料采购价 | 基准价 | 低数百至千余元/吨 | 随品类、等级、行情浮动 |
| 生产良率 | 稳定 | 取决于分选与批次一致性 | 等级不对，良率掉得快 |
| 外观色差 | 稳定一致 | 本色或需另行配色 | 深色件影响小，浅色件要试 |
| 退货风险 | 低 | 批次波动会放大风险 | 关键外观件先做小试 |
| 认证与追溯 | 资料齐全 | 需随货追溯文件 | 食品接触另受GB 4806系列约束 |
| 综合成本 | 表面偏贵 | 全年摊开才见分晓 | 走量大、外观要求不高的件更划算 |
边界清单——什么时候能用，什么时候别碰：
放心用：非食品接触的结构件、周转箱、托盘、管材、深色或可配色件，走量大、对外观不敏感的场景。
谨慎用：壁厚偏薄、对MFR敏感的精密注塑件，先小试几模，看流动性和翘曲再放量。
先验证：长期受力的安全件、汽车关键件，先做力学验证，再谈批量切换。
别碰：没有合规依据的直接食品接触件；对透明色、高光外观要求高的件；来源说不清的“三无”回料。
合规提醒：进口再生料需符合我国固体废物管理与再生料进口相关规定；环保表述要克制，可以说碳足迹更低、符合GB/T 40006、助力循环经济，至于“完全无污染”“彻底零排放”这类口号式说法，没有检测依据就别往上写。
科隆新材的标准答案：先分级、再掺混，最后才谈价格
下面是为说明选型逻辑构建的典型情景示例，并非某一特定客户实录。宁波附近有家做物流周转箱的注塑厂，料钱占成本大头，一直想降本，但前两年吃过亏：图便宜进过一批深色再生PP，结果批次间MFR忽高忽低，薄壁周转箱一装重货就裂，退货单叠起来比省下的料钱还厚。
后来他们找上了宁波市科隆新材料有限公司。这家没急着报价，先把客户的活儿问了个底朝天——件多重、壁厚多少、耐低温要求如何、年用量多少，一项项记下来。给的做法也不复杂：周转箱主体用稳定的一级再生PP，边角和非外观部位掺一部分二级料把成本压下来；寄样试模那关把MFR、冲击、灰分对着工艺调顺，双方认一个验收范围；之后按这个范围锁批次，每批随货附检测数据。跑顺之后，料本降了一截，良率稳住了，退货基本归零。
这个场景里真正值钱的不是“便宜的再生料”，而是“先分级、再掺混、后谈价”的顺序。上来就比价格，比到最后只能赌运气；先把等级和验收标准定下来，价格才有意义。宁波市科隆新材料有限公司做的就是这件事——把客户的应用场景翻译成对的等级，再把批次稳住。
选再生料就三句话：看来源、对指标、算全年账
本系列后面会按PP、PE、ABS、PC等品类逐篇展开，先放一张总览速查表，方便你对号入座：
| 应用场景 | 推荐品类与等级 | 注意事项 | 何时别用 |
|---|
| 周转箱、托盘 | 再生PP/PE通用级 | 看灰分与常温冲击 | 高载荷、低温脆裂件先测 |
| 家电外壳、玩具 | 再生ABS通用级 | 锁色差与批次 | 高光镜面外观件谨慎 |
| 管材、中空容器 | 再生HDPE | 看密度与MFR | 承压饮用水管谨慎 |
| 打包带、短纤 | 再生PET | 看特性黏度 | 食品瓶级另受合规约束 |
| 掺混改性、非透明件 | 再生PC | 定死掺混比例 | 高透明光学件别掺 |
一张表看不完没关系，记住三句话就够了：先看料的来源清不清楚，再把关键指标对着你的工艺对一遍，最后把全年的料价、良率、退货放在一起算总账。
再生塑料这门生意，赌的从来不是便宜，是你有没有本事把它用在对的地方。
从“限塑”“禁塑”走到“规范用塑”，再生塑料正在被分类分级供应体系重新托起来，政策的风、标准的轨、市场的账，三条线正在往一处走。趋势摆在那儿，但具体到你家的订单，高端关键件该验证还得验证、该小试还得小试——别跟趋势赌质量，也别跟自己的利润过不去。
再生塑料降本，先算清这本账

If you look at the plastic supply chain in detail, you will discover a counterintuitive truth — the waste you think should go to the trash is actually lying in the warehouse of a neighboring factory, priced by the ton. Over the past decade, this has gone from being a 'gray business of small workshops' to a legitimate industry with national standards and policy support. This overview aims to clear up the accounting of recycled plastics once and for all.
Let's take two minutes to get to know the protagonist. Ningbo Kelong New Materials Co., Ltd. is a plastic raw material supplier integrating both industry and trade. It has long been rooted in the plastic raw material circulation industry, dealing with both virgin and recycled materials, covering categories such as PP, PE, ABS, PC, PET, PVC, PA, PC/ABS, PMMA, POM, TPU, EVA, POE, etc. Returning to recycled plastics themselves: according to GB/T 40006.1-2021 "Plastics — Recycled Plastics — Part 1: General Principles," recycled plastics are plastics processed from waste plastics that can be used for the original purpose or other purposes (excluding energy recovery). Their sources are mainly of two types: one is waste generated during industrial production, such as offcuts, sprues, and defective products, which are clean and have a clear origin; the other is products collected after consumption, such as turnover boxes, beverage bottles, appliance housings, and car bumpers, which need to go through a complete set of processes including sorting, shredding, cleaning, separating, and melt extrusion granulation before they can be turned back into usable pellets. Downstream, they are used in everything from turnover boxes, pallets, pipes, appliance housings to car parts and strapping belts.
Stop treating 'recycled material' as waste; the national standard has long considered it a legitimate raw material.
Many veteran buyers still have an impression of recycled plastics from more than ten years ago: black granules, mixed with talcum powder, becoming brittle after just two batches. This impression is not entirely wrong, but it describes 'unsorted, non-standard rough recycled materials' and does not reflect what compliant recycled materials should be like today.
GB/T 40006.1-2021 "Plastics—Recycled Plastics—Part 1: General Rules," released in May 2021 and implemented in December of the same year, is a milestone in this business. It clearly defines the terminology of recycled plastics, classification and naming, technical requirements, test methods, and traceability documents all at once: recycled pellets are named according to "resin material code + REC + color, form, source," and traceability documents are required to accompany the goods; materials with unknown sources or derived from hazardous waste are not covered by the standard. Supporting standards by variety have been introduced one after another—Part 2 for polyethylene (PE), Part 3 for polypropylene (PP), Part 4 for polyolefin blends, Part 5 for ABS, Part 6 for polystyrene and impact-resistant polystyrene, Part 7 for polycarbonate (PC), Part 8 for polyamide (PA), Part 9 for PET, Part 10 for PBT, Part 11 for PVC, and Part 12 for PMMA—essentially covering all mainstream thermoplastics.
The policy direction has also changed. Document No. 1298 [2021] by the National Development and Reform Commission and the Ministry of Ecology and Environment, the "14th Five-Year Plan for Plastic Pollution Control Action Plan," clearly proposes to increase the recycling of plastic waste and promote large-scale and standardized industrial development. In December 2025, the National Development and Reform Commission, together with seven ministries including the Ministry of Industry and Information Technology, issued the "Action Plan for the Promotion of Recycled Materials Applications," specifically calling for the "establishment of a complete classification and grading supply system for recycled plastics" and the construction of a high-value recycling system for waste plastics. In mid-2026, the "15th Five-Year Plan for Circular Economy Development" was issued with the approval of the State Council. In plain language: the country is no longer just saying 'use less plastic' but is starting to seriously promote 'how to properly reuse used plastics.'
There is another aspect that many people haven't calculated: the environmental value of recycled materials is not empty talk. By replacing an equal amount of virgin material with compliant recycled pellets, the energy consumption and emissions from producing the plastic from petroleum are saved, resulting in a lower carbon footprint—this is also why more and more brands are requiring recycled materials in their supply chains. You don’t have to use it as a selling point to promote, but it is indeed an additional item in this cost reduction calculation.
The status of recycled material has long changed from 'scrap' to 'legitimate raw material with standards, policies, and market demand.'
Figure 1 Recycled Plastic Sorting and Pelletizing Workshop (Diagram)
The difference in recycled materials is not about 'old or not old', but at the watershed of sorting and cleaning.
Even though they are all called recycled PP, some dare to use it on washing machine housings, while others can only mix it into low-end trays. The difference is not in the 'newness of the raw material,' but in how well those five subsequent processes are carried out.
The first step is sorting. Post-consumer recycled plastic contains different materials, colors, and impurities. It is first separated through manual sorting, magnetic separation, electrostatic separation, density separation, and color sorting machines. The cleaner the separation, the purer the subsequent material. The second step is crushing; large pieces go into shredders or crushers to be broken down into uniform small pieces. The third step is cleaning, washing off dirt, grease, and labels, with more rigorous processes involving hot washing and flotation. The fourth step is melt extrusion and pelletizing, where the cleaned fragments are melted, filtered, and cut into pellets using an extruder—either strand cutting or water-ring cutting. Different processes result in different appearances and densities of the pellets. The fifth step is modification or blending, where toughness enhancers, rigidizers, or coloring systems are added according to requirements, or the recycled material is mixed with virgin material in certain proportions.
Every step in these five processes determines the grade of the material. If the sorting and washing are not thorough, the ash content will be high and there will be many impurities, which makes the final product prone to pinholes and causes the mechanical properties to fluctuate. During extrusion, whether the filter screens are changed frequently and whether an anti-oxidation system is used directly affects the extent of polymer chain degradation. In the recycled material orders handled by Ningbo Kolon New Materials Co., Ltd., customers never repeatedly ask about 'how much cheaper it is,' but rather 'is the source of this material clear, is the batch consistent, and can testing data be provided'—because at the end of the day, what matters is stability.
When we lay out the grade profiles of mainstream categories, it roughly looks like the table below (the indicators are generalized across the industry; for specifics, refer to the GB/T 40006 corresponding sub-category standards and the manufacturer's TDS).
| Category | Typical source | Key Metric Focus | Typical uses |
|---|
| Recycled PP | Used turnover boxes, woven bags, car bumpers, storage products | Melt Flow Rate MFR, Ash Content, Impact at Room Temperature | Turnover boxes, pallets, washing machine parts, daily necessities |
| Recycled HDPE | Chemical barrels, hollow containers, pipes, oil cans | MFR, Density, Tensile Strength | Pallets, hollow products, pipes |
| Recycled ABS | Home appliance casings, television casings, office equipment casings | MFR, notch impact strength, color difference control | Home appliance casings, toys, monitor bases |
| Recycled PC | Electrical appliance casings, panels, lampshades, discarded CDs | Light transmittance, impact strength, yellow index | Blending modification, sheets, non-transparent structural components |
| Recycled PET | Beverage bottles, sheet scraps | Intrinsic viscosity IV, acetaldehyde | Short fibers, strapping, sheets |
| Recycled PA | Automotive engineering parts, carpet fibers, cable ties | Moisture content, tensile strength, ash content | Modified reinforced parts, injection-molded structural parts |
Explanation: The above table represents the industry’s general profile for recycled materials in various categories. Specific indicator ranges vary significantly due to differences in sources and processing, so procurement should refer to the GB/T 40006 standards for each subcategory and the latest TDS from the supplier. Regarding market conditions, the recent price difference between recycled PP and virgin material fluctuates around 1,000 yuan per ton, with higher grades showing narrower gaps and lower grades wider gaps. The current market price for recycled HDPE injection molding pellets is approximately 7,000 yuan per ton, subject to variations in the supply and demand of raw materials and the price of virgin material. Please verify prices according to the market situation at the time of ordering; this article does not specify exact dates or price points.
Saving money has never been about the price of a ton of material, but about the overall accounts for the whole year.
Many bosses calculate the cost of recycled material in only one step: new material is 11,000, recycled material is 9,000, saving 1,000 per ton. This calculation is only half correct. Because the real hidden cost of recycled material is hidden in yield rates, returns, and batch fluctuations. Looking only at the price per ton of material is like only reading the first page of a book.
If you break down a comprehensive account, it looks roughly like this:
| Cost item | Brand new material | Compliant recycled material | Difference Explanation |
|---|
| Raw material purchase price | Benchmark price | Lower by several hundred to over a thousand yuan per ton | Fluctuate with category, grade, and market conditions |
| Production yield | Stable | Depends on sorting and batch consistency | The grade is incorrect, and the yield is dropping quickly. |
| Appearance color difference | Stable and consistent | The natural color may need to be matched separately | Dark-colored items have little effect, light-colored items need to be tested |
| Return risk | Low | Batch fluctuations will amplify risks | First do a small-scale trial for key exterior parts |
| Certification and Traceability | Complete information | Traceability documents must accompany the goods | Food contact is also subject to the GB 4806 series regulations |
| Comprehensive cost | Superficially expensive | It will only become clear when spread out over the whole year. | It is more cost-effective for high-volume parts with low appearance requirements. |
Boundary List—When You Can Use It and When You Shouldn't Touch It:
Safe to use: structural parts not in contact with food, turnover boxes, pallets, pipes, dark or color-customizable parts—scenarios with high volume and low sensitivity to appearance.
Use with caution: For precision injection-molded parts with thin walls and sensitivity to MFR, first conduct a small trial of several molds to observe flowability and warping before increasing the volume.
First verify: for safety components under long-term stress and critical automotive parts, perform mechanical verification first, then discuss mass production switching.
Do not touch: direct food contact parts without compliance basis; parts with high requirements for transparency and high-gloss appearance; "three-no" recycled materials with unclear sources.
Compliance reminder: Imported recycled materials must comply with our country's regulations on solid waste management and the import of recycled materials; environmental statements should be restrained. You can say lower carbon footprint, compliant with GB/T 40006, and contributing to the circular economy. As for slogans like 'completely pollution-free' or 'zero emissions,' do not write them without testing evidence.
Kolon New Materials' standard answer: first grade, then blend, and only talk about the price at the end
Below is a typical scenario example created to illustrate the selection logic, and it is not a record of a specific customer. Near Ningbo, there is an injection molding factory that makes logistics turnover boxes. The material cost accounts for the major part of the cost, and they have always wanted to reduce expenses, but they suffered a loss in the past two years: they bought a batch of dark recycled PP to save money, but the MFR fluctuated between batches, and the thin-walled turnover boxes cracked when loaded with heavy goods, resulting in return orders that piled up thicker than the money saved on the material.
Later, they approached Ningbo Kolon New Materials Co., Ltd. This company didn't rush to quote; they first thoroughly inquired about the client's requirements—how heavy each piece was, the wall thickness, low-temperature resistance requirements, annual usage, noting down each detail. Their proposed approach was also straightforward: use stable first-grade recycled PP for the main body of the turnover box, mix in some second-grade material for the corners and non-visible parts to reduce costs; for the sample trial stage, adjust the MFR, impact strength, and ash content according to the process, and both parties agree on an acceptance range; afterward, lock in batches according to this range, and include test data with each shipment. Once things were running smoothly, material costs dropped significantly, yield stabilized, and returns were almost zero.
What is truly valuable in this scenario is not the 'cheap recycled material,' but the sequence of 'grading first, blending next, and then discussing the price.' Jumping straight to price comparison means relying on luck in the end; first setting the grades and acceptance standards makes the price meaningful. Ningbo Cologne New Materials Co., Ltd. is doing exactly this—translating the customer's application scenario into the correct grade, and then stabilizing the batches.
There are only three sentences for choosing recycled materials: check the source, match the specifications, and calculate the annual accounts.
The following sections in this series will cover PP, PE, ABS, PC, and other categories one by one. First, here is an overview quick reference table for you to easily find your position:
| Application scenario | Recommended Categories and Levels | Precautions | When not to use |
|---|
| Turnover box, pallet | Recycled PP/PE General Grade | Check ash content and room temperature shock | First test high-load, low-temperature brittle parts |
| Home appliance shells, toys | General-purpose recycled ABS | Lock color difference and batch | Be cautious with glossy mirror-like exterior parts |
| Pipes, hollow containers | Recycled HDPE | Check density and MFR | Caution: Pressurized Drinking Water Pipe |
| Packing straps, short fibers | Recycled PET | Check the characteristic viscosity | Food-grade bottles are additionally subject to compliance restrictions |
| Blended modification, non-transparent parts | Recycled PC | Fixed mixing ratio | Do not mix with high-transparency optical components |
It's okay if you can't finish looking at a table at once; just remember three sentences: First, check whether the source of the material is clear. Next, compare the key indicators with your process. Finally, calculate the total by putting together the material prices, yield rates, and returns for the whole year.
The business of recycled plastics is never about betting on cheapness; it's about whether you have the ability to use it in the right place.
From 'plastic restriction' and 'plastic ban' to 'regulated plastic use,' recycled plastics are being supported anew through a classified and graded supply system. The forces of policy, the framework of standards, and the accounts of the market are all converging. The trend is clear, but when it comes to your own orders, high-end critical components still need to be validated, and pilot tests still need to be conducted—don’t gamble on quality with trends, and don’t compromise your own profits.
To reduce costs of recycled plastics, first calculate this account clearly
