What is LIMEX?

LIMEX is a new material mainly made from limestone,
that can become an alternative to paper and plastic.

Limestone is a sustainable raw material, with abundant reserves all over the world.
It is 100% self-sufficient even in Japan, and said to be almost inexhaustible.
We believe that this sustainable material can save the world.
Earth, a Planet of Stones.
Limestone, the raw material for LIMEX, is an abundant resource, and is 100% self-sufficient in Japan. Furthermore, since it is abundant around the world, and can also be recycled highly efficiently, it is virtually inexhaustible. Because it is a resource that is abundant everywhere, we believe it can save the world.

  • International Patents for LIMEX
  • In 2014, LIMEX was patented in Japan.
    The basic patent has been submitted in over 40 countries worldwide,
    and has already been patented in over 30 countries including Japan, China,
    Europe and the U.S. More than 10 other patents have been submitted as well.
    We will export the LIMEX technology and brand as a new Japanese technology,
    so that LIMEX becomes a material used commonly in the world.
We make the most use of resources and regenerate its value sustainably. A circular economy is the future we aim for.

The Sustainable Development Goals (SDGs) are the international goals from 2016 to 2030 stated in "The 2030 Agenda for Sustainable Development," adopted at the United Nations summit in September 2015.
The SDGs are comprised of 17 goals to realize a sustainable world. LIMEX can contribute to the following eight goals of SDGs.

Our Hope, Biodegradable LIMEX
Recently, more and more countries are banning the use of single-use plastic products such as plastic bags, food containers, cutleries etc. LIMEX is mainly made from limestone and uses polyolefin resin as a minority material, and we have started developing a biodegradable LIMEX that replaces polyolefin resin with 100% biomass-based and 100% biodegradable material, to be used in such countries.

We make the most use of resources and regenerate its value sustainably.
A circular economy is the future we aim for.

Upcycling: Going One Step Ahead of Recycling
Upcycling is different from conventional recycling. Upcycling is a new methodology of sustainable manufacturing, to add higher or another value to the original used product. In the case of LIMEX, the collected post-consumer LIMEX products (paper alternative products) will be upcycled into plastic alternative products.
The Future of LIMEX
The European Commission has announced its goal to eliminate single-use plastic packaging in the region by 2030 and to reuse or materially recycle all plastic packaging. We think this is a big chance for LIMEX. In regions such as Europe where the infrastructure for recycling is available, we will establish a model for LIMEX upcycling. In regions where the recycling infrastructure is not yet established, we will provide biodegradable LIMEX products.
