Focusing on green, Wanhua Chemical takes another step in the degradable field

Recently, the official website of the Meishan Municipal People's Government announced the environmental impact assessment information announcement (the first time) of Wanhua Chemical (Sichuan) Co.

According to the information on the public notice, the basic situation of the construction project is as follows:

(1) Project name: Polylactic acid integration project with an annual output of 75,000 tons

(2) Construction site: Meishan High-tech Industrial Park, Sichuan Province

(3) Construction nature: new construction

(IV) Construction content: The project mainly builds production workshops, warehouses, tank farms and other auxiliary facilities.

Since this is the first announcement of the project, there is not much information disclosed on the website, but we can also find from the past news that Wanhua Chemical's new polylactic acid (PLA) project may not be without a trace

On March 15, 2021, Xinhuanet released a long report - "Wanhua Chemical: Focusing on the main business to serve the society to be first-class", praising Wanhua Chemical's innovation and breakthrough, and paying attention to Wanhua Chemical's service to the society and sustainable development

The article mentioned that PLA is a very "reliable" product in the direction of the degradable plastics industry, but its intermediate raw material, lactide, still relies entirely on imports.

In addition, in December 2019, Wanhua cooperated with Professor Wang Zhengxiang of Tianjin University of Science and Technology to develop PLA production technology.

"Environmental protection is related to the living environment of human beings in the future, and the whole world is paying attention

According to Dr.

According to Huaan Securities, Wanhua Chemical has patent layouts in all aspects of PLA, and related products have been launched.

On September 22, 2021, Wanhua Chemical stated on the investor interaction platform that the company's PBAT project with an annual output of 60,000 tons is under construction, and PLA is undergoing pilot testing

Presumably the PLA project will be officially announced this time, and Wanhua Chemical has made adequate preparations in this field

At present, environmental protection has become the main theme of global development, and environmental protection policies at home and abroad are emerging one after another.

1.

Wanhua Chemical has deployed a 60,000-ton/year PBAT project in Meishan Base, Sichuan.

According to the information disclosed in Wanhua Chemical's 2021 annual report, the PBAT biodegradable polyester project at the Meishan Base in Sichuan has been successfully put into production

2.

Wanhua Chemical has also built a supporting natural gas-to-acetylene and formaldehyde industrial chain in Meishan Base, Sichuan, and uses natural gas to produce BDO.
The planned production capacity is 100,000 tons/year, which will provide raw materials for the downstream 60,000-ton/year PBAT unit
.

3.
Maleic anhydride

On November 30, 2021, Wanhua Chemical's official website announced the draft for comments on the environmental impact report of its 200,000-ton/year maleic anhydride project
.
It is mentioned in the report that currently degradable plastics are mainly divided into PLA, PBS, PCL, PHA, PHB, etc.
according to the raw materials.
Among them, PBS (polybutylene succinate) has low price, excellent mechanical properties, and processing heat resistance Good and other characteristics have become one of the most promising general-purpose biodegradable plastics at present.
The basic raw material for producing succinic acid, the main raw material of PBS, is maleic anhydride
.

From this, we can also speculate that the maleic anhydride of this project is likely to be used to make succinic acid and then used to make PBS degradable plastics
.

In addition, maleic anhydride can be used as a raw material for BDO in addition to producing succinic acid.
However, since the construction site of Wanhua Chemical’s maleic anhydride project is in Yantai Chemical Industrial Park, Yantai Economic and Technological Development Zone, Yantai Chemical Industrial Park has not planned PBAT, etc.
project, so it is unlikely to be made into BDO
.

Lead the organization to establish a biodegradable plastics industry alliance

In addition to actively deploying projects in the field of degradable materials, Wanhua Chemical also led the establishment of a biodegradable plastics industry alliance in May 2021.
According to reports, the alliance aims to build an open exchange platform for the industry, and welcomes experts in the field of biodegradable materials, Enterprises participate together to formulate application standards urgently needed by the market, actively promote the standardization, industrialization and marketization of scientific and technological innovation achievements, promote the healthy and steady development of the industry, and build a green and environmentally friendly brand
