住友化学：实现丙烯酸树脂的回收利用：化学回收PMMA
-为减轻环境负荷做贡献-
2021 年 8 月 23 日
住友化学：
我们决定在爱媛工厂建设丙烯酸树脂（PMMA、聚甲基丙烯酸甲酯）的化学回收示范设施。
丙烯酸树脂回收设备：
示范测试将于 2022 年秋季开始，样品将于 2011 年提供。
建立资源回收体系：
与此倡议并行
来自使用过的丙烯酸树脂的收集
从丙烯酸树脂回收到商品化
建立资源回收体系。
丙烯酸树脂：
除了在合成树脂中具有极高的透明度外，还具有优异的耐候性和加工性。
汽车尾灯罩
家电、水族箱、户外招牌、液晶显示器、
用于建筑材料、防溅板等。
被广泛使用的。
2020年全球需求量将达到130万吨。
预计未来将出现强劲增长。
确立原创基础技术：
丙烯酸树脂以MMA单体为原料进行热分解再生。
通过建立我们自己的基础技术，我们决定建造一个示范设施。

Sumitomo Chemical to Construct Chemical Recycling Pilot Facility for Acrylic Resin to Reduce Impact on the Environment
Aug. 23, 2021
Sumitomo Chemical
has decided to construct a pilot facility for chemical recycling of acrylic resin (PMMA, poly-methyl-methacrylate) at its Ehime Works in Niihama City, Ehime Prefecture, Japan.
The new facility
is scheduled to begin pilot tests in the fall of 2022 and to start providing samples in 2023.
In parallel with this project,
the Company will work to develop a recycling system for PMMA, from collection of used acrylic resin to recycling and reprocessing into products,
aiming for early commercialization of chemically recycled PMMA.
Acrylic resins,
which possess the highest level of transparency among synthetic resins as well as superior weatherability and processability,
are used in a wide range of applications, such as automotive tail lamp covers, electrical appliances, aquariums, outdoor signboards, liquid crystal displays, building materials, and protective partition panels to reduce the spread of droplets.
Global demand for acrylic resins
exceeded 1.3 million tons in 2020, and is expected to continue to grow steadily in the future.
For acrylic resin chemical recycling,
the Company has been pursuing development
in collaboration with The Japan Steel Works, Ltd. combining JSW’s continuous plastic decomposition technology
using twin-screw extruders with Sumitomo Chemical’s expertise on MMA (methyl methacrylate) monomers and acrylic resins that it has cultivated over the years.
With its own basic technology to pyrolyze acrylic resin and regenerate it as MMA monomer,
which is used as a raw material, now successfully established, Sumitomo Chemical has decided to construct a pilot facility.
