TBM has established an environmental policy to encourage all members working on a variety of businesses at multiple locations to come together and promote environmental awareness.

We use Life Cycle Assessment (LCA), which is a scientific method for quantitatively evaluating the environmental impact of the entire product/service life cycle or its specific stages. This is to comprehensively understand and reduce not only the environmental impact caused by TBM, but also the environmental impact caused upstream and downstream of the supply chain.
Our assessment started jointly with the Oki Laboratory of the Institute of Industrial Science, the University of Tokyo in 2016. From 2018 to 2019, we conducted the LCA on LIMEX Sheet and products made of LIMEX Pellet with Japan Environmental Management Association for Industry (JEMAI). From 2020, we are working on LCA with the cooperation of the Sustainable Management Promotion Organization (SuMPO), which took over the business of JEMAI's industry support department.
At the development and manufacturing stages, we use this LCA method to quantify the environmental impact at each stage of the product life cycle, identify the characteristics of the environmental impact for each product, identify areas for improvement, and confirm the effects of improvements. .

Reducing dependency on unevenly distributed resources

TBM develops, manufactures, and sells LIMEX mainly made from limestone, which is abundant throughout the world, thereby reducing the use of petroleum-based plastics, which utilizes oil that are mined only in limited areas of the globe. In addition, as it is said that 51% of the world's population will be at risk of high water risk by 2050 ^*, we provide LIMEX Sheet, which can be manufactured using less water.

Material Circulation

TBM promotes material circulation to prevent environmental problems associated with resource use, such as the depletion of natural resources and pollution from waste. In particular, we have been working on the use of offcuts at our own factories since the start of operations, and now we are able to reuse many of them as raw materials. We are also working to recycle our used products and waste plastics through our business.

Target

TBM Pledge 2030 sets the following three goals as Go Carbon Negative (to achieve carbon negative by 2030).

• Eliminate GHG emissions (Scope 1 and Scope 2) from TBM
• Reduce GHG emissions (Scope 3) in the value chain by half compared to fiscal 2020 levels
• Contribute to reducing GHG emissions throughout society

TBMの目標は、GHG（温室効果ガス）の排出削減目標達成を推進するために設立された国際的なイニシアチブ「Science Based Targets initiative（SBTi）」より「1.5℃目標」として認定されています。また、AmazonとGlobal Optimismが共同で立ち上げた「The Climate Pledge」（気候変動対策に関する誓約）に署名しました。
2024年のTBMからのGHG排出量（Scope 1・Scope 2）は2020年比で73%の削減、バリューチェーン上のGHG排出量（Scope 3）は、生産量や算定範囲の拡大等に伴い、2020年比で474％の増加となりました。 また、2024年のLIMEX製品の販売に伴うGHG排出削減貢献量*は、11,494 t-CO2eqとなりました。

GHG Emissions Reductions

TBMは東北LIMEX工場と横須賀サーキュラー工場において実質「100%再生可能エネルギー由来」「CO₂排出係数ゼロ」の電力を使用しています。これにより、両工場の操業に伴うエネルギー起源のCO₂などの温室効果ガスを大幅に削減し、お客さまにご提供しているLIMEX SheetおよびLIMEX PelletのサプライチェーンにおけるGHG排出量の削減に取り組んでいます。

Calculation and Information Disclosure

TBM calculates Scope 1, Scope 2, and Scope 3 GHG emissions and discloses them in our sustainability report. We strive to collect information necessary for reduction by identifying not only our own direct emissions but also indirect emissions in the value chain. We also place importance on disclosing the collected information to stakeholders.

Development of biodegradable LIMEX

海洋プラスチック汚染への対策方針は国や地域によって異なります。例えば、世界最大のプラスチック使用国である中国^*では、生分解性プラスチックの導入を積極的に進めています。 生分解性とは、微生物の働きによって、水とCO₂に分解される性質を指します。TBMは、2021年に韓国大手財閥である SKグループの化学素材大手SKCと連携してJV（ジョイントベンチャー）「SK TBMGEOSTONE Co., Ltd」を設立 し、生分解性LIMEXの開発・事業化を推進しています。

Utilizing Marine Plastics

TBM is working to recycle the plastic litter that has washed ashore on the coast and aiming to reduce marine litter and create businesses. We participate in "Project Ikkaku, an industry-academia collaboration jointly implemented by the Nippon Foundation, the Japan Advanced Science and Technology Organization for  Education, Human Development and Research (JASTO), and Leave a Nest Co., Ltd. As part of this, we made bags for collecting litter that has drifted ashore from marine plastics. We also support the recycling of oyster pipes by Scout Association of Japan's "Plastic Garbage Busters Daisakusen Upcycle Mission"
