We will promote the development of applications for LIMEX Sheet. In addition, we will sell TBM products to South Korea and the rest of the world, and respond to the global plastic problem and the needs of environmental materials that differ depending on the region.
Background/Summary
Environmental issues such as climate change, resource depletion, and water resource crises are progressing rapidly around the world, and it is imperative that we respond to them not only at the national level but also at the corporate level. In particular, each country has its own regulations regarding plastics, and 127 countries1, including Japan, have banned or restricted the use of plastic bags. On the other hand, due to population growth and economic growth in emerging countries, the global plastic resin market size is expected to grow at a CAGR of 4.5% from 2020 to 2027, reaching $522.5 billion by 20272. . China is actively promoting the introduction of biodegradable plastics amid growing demand for alternative materials to plastics. By 2030, the size of the biodegradable plastics market in China will grow approximately seven times (approximately 1.4 trillion yen) 3.
Since its establishment in 2011, TBM has been developing materials for LIMEX, which uses inorganic substances such as calcium carbonate as the main raw material. LIMEX has been highly evaluated for its contribution to climate change countermeasures through resource conservation and CO2 emission control, and has been introduced at COP and G20 international conferences. increase. Currently, it is possible to produce materials not only at our own factory but also at fabless, and we are building an overseas production system and supply chain. In Japan, more than 6,000 companies and local governments have introduced products using LIMEX as an alternative material to plastics and paper.
The SK Group, the third largest conglomerate in South Korea and centered on petroleum refining and telecommunications, is currently using biotechnology and renewable energy as growth drivers, and aims to become a leading company in the ESG field by rebuilding its business portfolio. I'm here. The SK Group, which leads ESG management by becoming the first Korean company to join "RE100 4" last year, has set up a management strategy that uses the environmental regulations of each country as new opportunities for growth.

Overview
TBM and SK Group have agreed to enter into a capital and business alliance and will collaborate in the following areas:
1. Sales of TBM products in Korea and globally, utilizing SK Group's global sales channels
2. Developing LIMEX applications that meet the needs of the SK Group and its customers
3. Commercialization of a joint venture to develop, manufacture, and sell biodegradable LIMEX using biodegradable plastic (PBAT) manufactured by the SK Group
TBM and SKC have signed an agreement to establish a joint venture to jointly promote the exclusive development and commercialization of biodegradable LIMEX using SK Group's biodegradable plastic (PBAT). While high cost has been one of the main reasons biodegradable plastics have not been widely adopted to date, biodegradable LIMEX is price-competitive and has the potential to be widely adopted in the market. Furthermore, calcium carbonate, the primary raw material for LIMEX, is abundant, has a low risk of depletion, and has a stable supply. Therefore, it is significantly cheaper than petroleum-based plastics and biodegradable plastic raw materials, and its low risk of depletion contributes to its price stability. By utilizing TBM's material design technology for highly loaded calcium carbonate resins and SKC's high-strength biodegradable plastic (PBAT), it will be possible to develop biodegradable LIMEX that is price-competitive compared to conventional biodegradable plastics, while also offering heat and impact resistance.
