LIMEX as a plastic alternative
From the perspective of "reduce," which means reducing the amount of resources used during manufacturing, LIMEX can contribute to reducing the amount of plastic used because it is made primarily from calcium carbonate. Replacing polypropylene with LIMEX, which contains 60% calcium carbonate by weight, can reduce the amount of plastic used by approximately 33%. From the perspective of "recycle," we are promoting "mechanical recycling," which utilizes the recycling performance of LIMEX to collect used LIMEX products and regenerate them into new LIMEX products with added value as plastic alternative.
Amount of petroleum-based resin used
*When compared with the same volume
By using LIMEX, you can reduce the amount of petroleum-based plastics used.
LIMEX can be recycled as for plastic alternative products.
Features as an plastic alternative
Reduce plastic usage and
GHG emissions
炭酸カルシウムなど無機物を50%以上（重量ベース）含むため、従来の石油由来プラスチックに比べ、石油由来プラスチックの使用量を大幅に削減でき、原材料の調達から処分までのライフサイクル全体でCO₂等の温室効果ガス（GHG）排出量を減らすことができます。
Supply stability
Low price fluctuation risk
Limestone is a resource that exists abundantly all over the world, so it has superior supply stability compared to petroleum-based plastics, and can be offered at a stable price with little price fluctuation.
No need to buy new
machinery and equipments
Like general-purpose plastics, it is compatible with a variety of molding methods such as vacuum, injection, and inflation. Because processing does not require special equipment and existing molding equipment can be used, a fabless model supply chain can be built both domestically and internationally.
Bio LIMEX, limestone and plant-based resin
Plastic-related laws and regulations are being implemented in various countries, such as banning the use of plastic bags and disposable plastic containers. "BioLIMEX," which replaces petroleum-based plastic with bio-derived materials, is designed to reduce greenhouse gas emissions such as CO2 by approximately 50% throughout its life cycle, from raw material procurement to incineration, and was also used as equipment for the G20 Osaka Summit. Garbage bags made from BioLIMEX were adopted as operating items for the G20 Osaka Summit held in June 2019.
