New International Standards for Determination of Biobased Content of Rubber Products Issued Aiming at the popularization of environmental- and resource-friendly rubber products

New international standards for determination of biomass-based (biobased) content of rubber and rubber products have been issued based on the proposal filed by Japan to the International Organization for Standardization (ISO), aiming at the popularization of rubber products derived from biomass raw materials in order to decrease environmental burdens and reduce the consumption of petroleum resources. These standards are expected to encourage the global-level popularization of environmental- and resource-friendly rubber products derived from biomass raw materials and also to contribute to enhancing the international competitiveness of Japanese companies with strengths in developing technologies for the products.

1. Background

The rubber industry in Japan, mainly involved in the production of tires, has been increasingly placing importance on the promotion of energy conservation and the utilization of renewable resources during raw-material production, manufacturing processes, product utilization and disposal of products. To facilitate these efforts, a system for adequately evaluating products as achievements of resource-conservation manufacturing was necessary.

2. Outline of the international standards

To meet this need, in May 2014, Japan submitted a proposal for new international standards for determination of the biobased content of rubber and rubber products to the ISO. Following this, for approximately three years, the ISO/TC45 (rubber and rubber products) held international meetings to examine the proposal and organize new standards with other member countries. As a result, on August 14, 2017, the ISO officially issued three new international standards as below.

ISO 19984-1

Rubber and rubber products -- Determination of biobased content --
Part 1: General principles and calculation methods using the formulation of the rubber compound

ISO 19984-2

Rubber and rubber products -- Determination of biobased content --
Part 2: Biobased carbon content

ISO 19984-3

Rubber and rubber products -- Determination of biobased content --
Part 3: Biobased mass content

Key points of the issuance of new standards (ISO 19984) are as follows.

(1)The new standards clarify the definition of biobased content of rubber and rubber products and stipulate the methods for determining the biobased content based on the calculation of the existing information on raw materials and compounds.

(2)They stipulate the testing methods for determining the biobased content of compositions for which information on raw materials and constituent compounds is unknown.

3. Expected effects

Making use of biobased content as an item for evaluating the quality of rubber and rubber products is expected to encourage the rest of the world to evaluate the quality of Japanese products more highly, as Japanese enterprises have strengths in technologies for utilizing renewable resources, e.g., fermentation and enzyme technologies; thereby improving the international competitiveness of Japanese companies which possess these technologies. Moreover, these standards may drive rubber industries both inside and outside Japan to shift from petrochemical materials to biomass-derived raw materials, and this is expected to contribute to promoting energy conservation and reducing greenhouse gas emissions.

4. Japan's other efforts for international standardization

The Japan Rubber Manufacturers Association (JRMA) has been promoting activities for international standardization, as seen in the JRMA's achievement in its delegate obtaining the post of Secretariat of ISO/TC45/SC2 (testing and analysis). In addition, Japan submitted a proposal to the ISO for international standardization concerning methods for inspecting the precision of test methods to be applied to all testing standards adopted in the rubber industry, and based on this proposal, the ISO issued a new standard titled “ISO 19983: Rubber -- Determination of precision of test methods.”

Note: This successful standardization is partly due to the achievements using the Expenditures for the Strategic Development of International Standards Project for Rational Energy Use (international standardization for methods for measuring biobased content of rubber products), which METI commissioned to a private entity.
