One, recognize renewable plastics
The source of recycled plastic is the plastic products after use.
The huge plastic production is the basis of renewable plastic recycling, China's plastic industry after more than 20 years of rapid development, the production and sales of plastic products in the world's first, about 20% of the world's total output.
Due to the scale of comprehensive utilization of renewable plastics in China is larger than that of other countries and regions, In the past a long period of time, China has gradually become an important plastic recycling country from the global recycling, making a great contribution to the treatment and processing of global waste plastics.
Two, renewable plastics and degradable plastics
Recycled plastic is a kind of plastic raw material which is recovered from waste plastic after processing.
The biggest advantage of recycled plastics is that the price is cheaper than new materials and degradable plastics, and can be processed according to different performance needs, only some aspects of the attributes of plastic, and make the corresponding products;
Degradable plastic refers to a kind of plastic whose various properties of products can meet the use requirements, the properties remain unchanged during the storage period, and can be degraded into environmentally harmless substances under natural environmental conditions after use.
Third, market prospects
1. Policy support
Comprehensive utilization of waste resources is an industry encouraged by the state.
In recent years, the state has promulgated a series of policies and regulations to ensure the orderly and healthy development of the industry. The plastic recycling industry is the main component of the development plan of "waste-free city", "circular economy", "ecological civilization system reform" and so on.
2. There is no time to stop plastic pollution
Plastic poses a great threat to environmental pollution and is difficult to be recycled. China is faced with the contradiction of large amount of waste plastic and low recovery rate. Among them, the proportion of effective, high-quality and environmentally friendly recycling is lower, and there is a lack of convenient and economic large-scale environmental recycling methods in the market.
In particular, it lacks the core technology and equipment with large scale, good economic benefit and driving effect.
Four, subdivision circuit introduction
Recycled plastics can be divided into recycled PS plastics, recycled PET plastics and recycled PVC plastics, among which recycled PS plastics and recycled PET plastics are in the most urgent need
Note: PS plastic is mainly used for making disposable lunch boxes;
PET plastic is mainly used to make beverage bottles.
1. Recycled PS plastics
Because PS has the characteristics of corrosion resistance and not easy to decompose, a large number of PS, especially disposable EPS packaging, are carelessly discarded by people and caused by pollution, forming a "white pollution".
The recycling and utilization of PS not only meets the requirements of China's basic national policy of environmental protection and resource conservation, but also makes full use of its intrinsic value to realize circular economy.
Downstream applications of recycled PS plastic mainly include building materials (mainly building insulation boards and baseboards), photo frames, picture frames, picture frames, sole materials, advertising boards, toys and other injection products, etc.
Downstream industry applications to home building materials market.
Recycled PET plastic
PET products are mostly disposable consumer goods, followed by a large number of waste PET materials.
Waste PET materials are not easy to be degraded by air or microorganisms in a short time, occupying a large amount of space, resulting in environmental pollution and visual pollution.
Recycling and regeneration of discarded PET has become people's choice. Regenerative PET is only slightly inferior to original PET in gloss, and the rest performance is not different. The growth mode of PET industry completely relying on the expansion of original PET capacity will be transformed, and the renewable PET market has a broad prospect.
Downstream applications of recycled PET mainly include packaging boxes, beverage bottles, textile and clothing, etc.
Downstream industry applications are mainly for daily consumer goods, and recycled PET has the characteristics of low end surplus and high end supply shortage.
3. Recycled PVC
PVC recycled material has the characteristics of high mechanical strength, light weight, insulation performance, high strength, easy processing, corrosion resistance and so on.
Widely used in various fields, such as construction, pipe, electronic appliances, automotive industry, packaging and other fields.
The application of PVC recycled material has great advantages, especially in the field of pipe, but its recycling process has certain limitations, indoor use of old material is equal to new material;
And outdoor PVC has no recycling value.
4. The recycled HDPE
HDPE is most used in packaging film and various containers, such as food containers, milk bottles and so on.
Because the bottles and containers are easy to collect, so the recycling rate of this kind of products is also very good, HDPE recycling technology is quite mature in China.
The market of HDPE recycled material is very large, but the recycled material will lead to the deterioration of product performance, so at present, HDPE recycled material almost need not be used in food packaging.
5. Recycled ABS plastic
ABS recycled material has good comprehensive performance and is widely used. It is commonly used as engineering plastics, which is used in electrical cases, TV cases, instrument cases, car panels, decorative materials and so on.
6. Recycled PP plastics
PP recycled material is polypropylene recycled material, polypropylene material used once again, after the thermal extrusion granulator recycling machine, PP recycled material can be used as raw material again.
Five, the status of the industry
The significant characteristics of China's renewable plastics industry are that the scale of enterprises is generally small, mainly family workshops, the use of extensive and simple technology, weak awareness of environmental protection, most small enterprises are not enough technical input, the treatment of renewable plastics technology is still mainly manual and old equipment, the technical level of the industry is generally not high.
Family workshops recycle goods of different quality levels, old production equipment, direct emissions of pollution, resulting in secondary pollution of the environment, at the same time, the quality of their production of recycled plastic products is poor, mainly for low-end market.
In general, there are few large and medium-sized enterprises with economies of scale in the field of domestic renewable plastics, and the industry competition pattern is scattered, so there is a certain gap in the supply of this field.
It is worth mentioning that with the issuance of the ban on waste in the plastic industry, many enterprises can no longer import waste plastics from abroad, so domestic enterprises transfer their production capacity to overseas, in this respect, to reduce the direct material cost.
6. Relevant listed companies
Sanlian rainbow,
Implemented in the field of recycled plastic "bottle to bottle" closed loop, and take the lead on the international launch of single production capacity of 50000-10 tons/year scale overall technical solutions, the final product won the Coca-Cola, nestle, world-class food and beverage companies such as danone food grade packaging material safety qualification certification, to achieve high added value with recycling.
The blond technology
Since 2004, we have been exploring the industry of recycled plastics. We are one of the earliest explorers of recycled plastics in China.
In June 2014, Jinfa Technology was awarded "One hundred Backbone Enterprises of Comprehensive Utilization of Resources" by the National Development and Reform Commission. Since 2015, jinfa Technology has owned the State Key Laboratory of High Quality Utilization of Polymer Material Resources.
At present, it has 55 regenerated plastic modification production lines, backed by the key plastic recycling industry, the formation of two major bases in Guangdong Qingyuan and Jiangsu Pizhou, with 5 high-performance regenerated modified plastic production workshops.
At present, it has an annual production capacity of 290,000 tons, with an annual capacity of 190,000 tons under construction, and the annual capacity will reach 480,000 tons by the end of 2022.
British families and regeneration
Since its establishment in 2002, the company has become a global leader in plastic recycling and recycling by persisting in innovation, steady expansion and strategy.
In 2017, the construction of A PS regeneration and granulation plant in Malaysia began.
The Malaysian plant started production in March 2018, and by the end of 2018, most of the pelleting capacity of its domestic plants was relocated to the Malaysian plant.
Malaysia allows the import of renewable plastic raw materials, Malaysia factory can normally use foreign renewable PS plastic recycling granulation.
In 2019, we will build a PET recycling project of 50,000 tons per year in Malaysia.
Its subsidiary, Vietnam Inke, is preparing for the annual production of 2.27 million boxes of plastic decorative frames and wires, which is expected to be put into production at the end of this year or early next year.
