Kaneka completes 5000 t/a PHBH® plant

Company will continue to provide value globally as a solution provider based on the idea that they help make the world healthy

Kaneka Co., Ltd. (headquartered in Minato-ku, Tokyo) has completed the capacity enhancement work for “Kaneka Biodegradable Polymer PHBH®” at its Takasago Plant as scheduled. The completion ceremony was held on December 17th. The investment amount was approximately 2.5 billion yen (41 million EUR) [1], and the production capacity is about 5,000 tonnes / year, five times the previously existing capacity.

In recent years, marine pollution caused by microplastics has become a global social problem as it affects ecosystems. However, PHBH®, a 100% plant-derived biopolymer developed by Kaneka, is certified to biodegrade in seawater. The material is certified “OK Biodegradable MARINE” [2] and is expected to contribute to reducing marine pollution. In addition, it has been added to the positive list of the US Food and Drug Administration (FDA), the Sanitation Council for Polyolefins [3], and the European Commission [4].

In Europe, various regulations have been incepted to reduce disposable plastics. In France, especially, regulations are tightened from January 2020, and PHBH® sales are expected to expand rapidly. In Japan, approximately 10,000 stores of Seven-Eleven Japan have begun adopting PHBH® straws for Seven Cafes since November, and Kaneka is jointly developing cosmetic containers with Shiseido. In addition, many global brand holders are studying a wide range of applications such as straws, plastic bags, cutlery, and food containers and packaging materials, and the 5,000 ton/year plant is expected to become fully operational at an early stage.

This is not limited to the expansion of production capacity, but it is expected that construction of a full-scale mass production plant will be decided at an early stage in order to meet the growing demand on a global scale in a timely manner.

Kaneka will continue to provide value globally as a solution provider based on the idea that they help make the world healthy.
