Green Nano is a Japan-originated technology
that significantly reduces CO₂ emissions during combustion
by adding only a small amount to ordinary plastics.

What is Green Nano?
Green Nano is neither a product nor a material.
Simply add a small amount of functional masterbatch to your regular ingredients as a raw material.Significantly reduces CO₂ emissions generated when plastic products are incinerated.This is a next-generation eco-technology developed in Japan.
Sustainable initiatives with regular facilities
Unlike plant-derived plastics, etc., which are inferior in transparency and strength, the performance of ordinary plastic products is largely maintained because only a small amount of functional masterbatch is added.
The design, materials and production facilities can remain the same at the time of introduction so there is almost no labor or initial cost. Since only a small amount of Greeen nano is added, it is said to be one of the most environmentally friendly plastics that can be "eco-friendly" at a low cost.
Functional Masterbatches
What is a functional masterbatch?
Green Nano functional masterbatches are created by mixing Green Nano components (carbonization accelerators, dispersants, etc.) with a base resin (solvent solution). This means that we may customize masterbatches suitable for your products and consider a variety of materials.
Examples of functional masterbatches (dispersion liquids)
PP／HDPE／LDPE／LLDPE／PET／PS／ABS／PA
solvent dispersion / water dispersion, etc.

Production method for functional masterbatches (dispersion liquids)

Functional masterbatches for uniform dispersion of carbonization accelerators.

Functional masterbatches contain additives (carbonization accelerators) that reduce CO₂ and are added in appropriate amounts to plastic molding materials, so that the carbonization accelerators are appropriately dispersed in the molding plastic. The moderate dispersion of the carbonization accelerator in the molded plastic allows a more effective chemical reaction to occur, resulting in an eco-plastic with a sufficient CO₂ reduction effect even with only a small amount added.

Principles of CO₂ Reduction

Carbonization Accelerator

●The carbonization accelerator acts as a catalyst for dehydrogenation, promoting the carbonization reaction that occurs when flammable gases are generated.
●Carbides are produced in greater quantities than usual.
●As carbon is trapped in the residue (ash), the amount of CO₂ released into the atmosphere is reduced.

Combustion Experiments
Introduction of Combustion Experiment Methods
The CO₂ gas concentration emitted by direct combustion in a heating device that resembles an incinerator is measured in real time to determine the difference in CO₂ generation.

■ Specimen Size (per measurement)
Size: about 2 to 5 cm square / Weight: up to ~1g
■ Measurement time: time from start of measurement until CO₂ reaches 0 vol%.

※However, in stoker furnaces, which account for nearly 80% of waste incineration facilities in Japan, chemical reactions due to thermal decomposition have already occurred in the drying and preheating section (approximately 200°C to 500°C) of the stoker furnaces and the typical heating temperature for combustion tests is set at 400°C as a typical temperature at which resinous materials react violently in the combustion test.

※CO₂GAS amount converted as per unit weight of test piece
※Average occurrence (n5 average value: maximum and minimum values excluded)
※The above data is for reference only. The above figures may not be achieved even with the same base material.Reduction rates vary depending on product composition and blending ratio.

Case Studies
Another feature of this product is that its addition rate is only 3%, which hardly impairs the transparency and strength of plastics. (*1) Please contact us separately regarding PL certification.

*1: Changes in transparency and strength of plastic are the opinions of individual customers that are not guaranteed.
Before using the product, please be sure to make a sample to check the compatibility with the actual product. For more information, please contact the department in charge.

Introduced Industries
Apparel, cosmetics, toys, foods, household goods, etc.
Examples of Processing Results
Blow molding, extrusion molding, injection molding, vacuum molding, fibers, nonwoven fabrics, etc.
The answer to the microplastic problem lies in ecology, even when it has became burnable trash.Dispose it properly and be eco-friendly.

Problems with plastics
Microplastics from "illegal dumping of garbage" could be prevented if they are properly recycled or incinerated.On the other hand, "global warming caused by CO₂ emitted during incineration" has been recognized as a problem around the world　and early action is called for.
A new way thinking about plastics
Green nano," which is recyclable and reduces carbon dioxide emissions" when incinerated, is attracting attention as a new technological solution to the problems of microplastics and global warming in future society.
