Marine Biodegradable Materials Market in Japan: Key Research Findings 2020
Yano Research Institute (the President, Takashi Mizukoshi) carried out a survey on the domestic marine biodegradable materials market and found out the market trends and the future perspectives by application.
Summary of Research Findings
All the marine biodegradable materials, such as paper, cellophane, biomass composites, and marine biodegradable plastics, have both advantages and disadvantages, so that there is not yet an almighty material that can be utilized for any applications in any conditions. Therefore, the development of such materials is underway to make the best use of each characteristics of each material.
Still, there is limit for each of such materials to beat the existing plastics. The efficient way for such materials to achieve actual implementation is to share the advantages and complement the disadvantages of each other. In order to replace plastics such as for container packaging, each manufacturer of marine biodegradable materials had better join hands and share the information and knowledges that they possess, regardless of the company and regardless of material type. For the new technologies to spread and be accepted widely, it seems to be better to welcome each other rather than being secretive
Imperative to Establish Procedures to Examine Status of Marine Plastic Waste and Methods to Assess Marine Biodegradability
The first step for solving the problem of marine plastic waste with the countries worldwide is to establish the survey procedures objective to grasp the actual status of the pollution. Currently, because the obtained data differ by each country without internationally authorized survey method, the data acquired cannot be trusted.
Next, it is imperative to establish the official method to assess marine biodegradable materials for their biodegradability in ocean. Currently, TÜV AUSTRIA Belgium, one of the international certification authorities, has its certification “OK Biodegradable MARINE,” which Kaneka, a Japanese manufacturer, is one of those that have been certified with its marine biodegradable PHBH®. Other Japanese manufacturers, Futamura Chemical Co., Ltd., Business Innovation Partners Co., Ltd., and Daicel Corporation, are applying for TÜV AUSTRIA Belgium certification of their respective of marine biodegradable plastics which are expected to emerge in the market from latter half of 2020 to 2021.
Although the materials certified by TÜV AUSTRIA Belgium are sure to be superior in marine biodegradability, they are not enough to guarantee 100% for their safeness not to exert bad influence to the natural ecosystem based on scientific ground, because of lack of internationally unified criteria for testing and judgement.
This is because no testing method completely established at ISO (International Organization for Standardization). In order for marine biodegradable materials to be practically applied, establishment of scientific knowledge for the two viewpoints is imperative.
