Analysis of the development status and prospects of PBAT biodegradable plastics!

Brief Introduction

With the increase in global environmental protection, "plastic limit" has been implemented in more than 60 countries. my country began to encourage the promotion and application of degradable plastics in 2004, and began to implement "plastic limit" in 2008. In recent years, regulations and measures have become more stringent. On January 19, 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment announced the "Opinions on Further Strengthening the Treatment of Plastic Pollution", proposing restrictions and prohibitions in stages (2020, 2022, 2025) Action goals and measures for using non-degradable plastic products. Under strict plastic restrictions and bans, it is imperative to develop and apply biodegradable plastics. PBAT is a fully biodegradable plastic, which can be widely used in supermarket shopping bags, take-out meal boxes, agricultural mulch and other fields. With the introduction of the "plastic restriction order" and the expansion of the green consumer market, biodegradable plastics such as PBAT have shown good market prospects and have become a hot spot for investment and attention in the current domestic degradable plastics field.

Degradable materials have undergone changes in the development of substrates, and finally, biodegradable plastics have become the mainstream of development.
Biodegradable plastics are plastics that degrade into small molecules or low-molecular compounds such as carbon dioxide and water under natural conditions such as soil and sand. Such degradable plastics have been the focus of research and development in the field of degradable plastics in the past 10 years.

According to the source of raw materials, biodegradable plastics include fossil-based biodegradable plastics and bio-based biodegradable plastics. The former are produced from coal, petroleum, and natural gas raw materials, and mainly include dibasic acid glycol copolyester series (including PBAT). , PBS, PBSA), polycaprolactone (PCL), polyglycolic acid (PGA), polyvinyl alcohol (PVA) and CO2 copolymers, etc.; the latter is produced from biomass raw materials, mainly polylactic acid (PLA), poly Hydroxy fatty acid esters (PHA), all starch-based materials, cellulose materials, etc.

The chemical name of PBAT is poly(butyleneadipate-co-terephthalate) and the English name is Poly (butyleneadipate-co-terephthalate). It is a copolymer of butylene adipate and butylene terephthalate. It has the characteristics of PBA (polybutylene adipate) and PBT (polybutylene terephthalate), which has good mechanical properties, and high ductility and elongation at break It also has excellent biodegradability and is a fully biodegradable plastic with excellent performance. As an important petroleum-based biodegradable plastic, PBAT has convenient sources of raw materials and low production cost, which is a hot spot in the industry.

Due to the general increase in environmental awareness, various countries have begun to implement plastic restrictions. The price of plastic particles has risen and the supply exceeds supply. The shortage of production capacity and the huge market demand have created certain obstacles to the full implementation of green and pollution-free plastics. The SUMINO Biodegradable granules making line came into being.
The degradable granule granulation line currently uses the mainstream degradable plastics PLA, PBAT and PVA as raw materials. After adding starch and other completely degradable materials, the characteristics of the produced granules will not change and the production cost of enterprises will be reduced.
