ELEMUS researches the power of natural materials based on its own
theories and develops materials by interpreting them in new ways.
New materials from plant resources ®sustimo
“SUSTIMO” is a patented technology developed mainly by the Tokyo Metropolitan Industrial Technology Research Institute (TIRI),
a local independent administrative corporation and “SUSTIMO” is a 100% biomass molding material
made from 100% plant resources, made from finely ground cedar and cypress wood powder and sap from lacquer trees.
This is a highly heat-resistant material with physical strength almost equal to that of ABS resin,
combined with antimicrobial and high virus resistance, which can be used in various applications.
The materials used for raw materials are finely ground wood powder from cedar, cypress, and other woods, and sap from lacquer trees.
Since SUSTIMO® uses wood chips and unused thinned wood that cannot be used for building materials or furniture as raw materials, forest resources can be effectively utilized. In the process of growth, trees can absorb carbon dioxide from the atmosphere and fix it in their bodies. But a fully grown tree cannot fix carbon dioxide in its body, so it must be cut down and planted a new one to reduce the carbon dioxide in the atmosphere. SUSTIMO® is made from wood which has fixed carbon dioxide, so the more we use it, the more we reduce the total amount of carbon dioxide in the atmosphere..
(the natural lacquer from the Asian lacquer tree)
The sap of the lacquer tree is the milky white sap that exudes when the bark is damaged. It is a natural resin that becomes available for collection when the tree is 10 to 15 years old. URUSHI has been used by humans as a paint and adhesive for more than 9,000 years, but now it is not used much anymore. “URUSHI” lacquer is a material which can be cultivated and harvested continuously on a sustainable basis like natural rubber, so it will be a natural resin material with little impact on the environment. After the “URUSHI” trees are cut down, they can be used as raw materials for SUSTIMO® and then they can be planted again to reduce the amount of carbon dioxide in the atmosphere.

・The amount of carbon dioxide absorbed
in the raw material
The amount of carbon dioxide absorbed in the raw material of 1 kg of SUSTIMO® is about 1kg-CO2/kg. (Note 1) Estimates based on the use of 1,000 cedars/ha aged 36 to 40 years (by Japanese Forestry Agency)
(Note 2) Calculated based on data from the Ministry of Economy, Trade and Industry and the Forestry Agency.
・Carbon dioxide emissions generated
in the manufacturing process

Feature 2 : Antibacterial and antiviral properties
The antibacterial (1) and antiviral (2) properties of “URUSHI” lacquer have been scientifically verified by the Kanagawa Prefectural Industrial Research Institute.
Antibacterial testing / *1 by ISO22196 after 24 hours
Staphylococcus aureus 99,9% decrease
Escherichia coli 99,9% decrease
Antiviral testing / *2 by ISO21702 after 24 hours
type A influenza virus 99,9% decrease
Feature ３ : International patent
It has been patented in five countries including Japan.
Looking for joint development
partners using SUSTIMO®
What kind of products can be made?
In addition to the above, we can also handle any other products that use plastic.
