Cellulose base Biodegradable Resin Material
(100% Nature Biomass base, No Petroleum)
We persist to the ideas of making 100 % Nature Biomass based Biodegradable
Materials. NO Petroleum.
PLA, PHA type, starch based biodegradable resins are
good materials because they are also biomass based materials.
However, they are made from human food such as grains,
potatos, sugarcane etc… And there is a risk in the near future
that human food will be consumed
to make these biodegradable resin materials.
Therefore, it is ideal to make biodegradable resin from non-edible biomass.
Cellulose is most ideal because they are most abundant natural resources
on this planet. We can use waste wood such as thinner woods.
When large production is achieved, price should be economically friendly too.
Cellulose + Nano Cellulose Composite ??
100 % nature biomass based materials and as harmless as possible to the environment. No petroleum origin materials.
Recently, researchers have been trying to make cellulose based resin by saccharification of cellulose with acid or enzymes. However, decomposition process and pre-treatment process are troublesome processes so that cost will be too expensive for real application.
We made more simple process to make thermoplastic cellulose.
Tensile strength 42 – 54 MPa
We will keep trying to improve resin properties such as mechanical strength, crystallinity, molding property, heat resistance etc…
Nano Cellulose Composite is also possible.Cellulose + Nano Cellulose Composite ??

Main bone frame structure of all plant cell wall and can be
obtained by breaking down plant fiber into nano size level.

Nano cellulose (iron reinforcing bar)

Nano Cellulose
1. Strong and light weighted （theoretically, as light as 1/5, and
as strong as 5 times of iron steel)
2. Economically cheap
3. Sustainable, recyclable and environmentally friendly material
4. Large surface area（more than 250m2/g）, good absorbent, good scaffold
5. High gas barrier property
6. High biological compatibility
7. Thermal expansion coefficient is low (1 / 50 of glass). This is very useful property at plastic molding
due to its dimensional stability.
8. Nano cellulose can be made from plant, tree, paper, waste wood, paper scrap etc…
9. Nano cellulose can be used as reinforced material. Next generation fiber material next to glass fiber,

Biodegradable plastic is not largely used yet, why ?
Compared to conventional plastic such as
PP, PE, PVC, PMMA, Nylon, PS, ABS etc…
1.Mechanically weak
2.Thermally weak
3.Deformation at molding (at heating)
4.Low crystallinity
5.expensive

and CO2 by the work of microorganism in
natural environment.

Nano cellulose is the next generation
environmentally friendly material that can
be taken from plant, woods.

Biodegradable Nano Cellulose1. Improve mechanical strength
2. Increase temperature durability, heat resistance, increase glass
transition temperature
3. Lower the thermal expansion coefficient
(prevention of heat deformation for plastic molding)
4. Increase crystallinity
It has a great meaning to improve these properties with
biodegradable material because this is also possible with
glass fiber, carbon fiber, but they are not biodegradable.

By making PLA + Nano Cellulose Composite, mechanical strength has increased.
On top of that, It was found that biodegradability also accelerated.
We are planning to measure biodegradability with other plastics as well.

Influence of biodegradability of PLA by mixing with nano cellulose
All of sample have peaks almost
at the same position.
The new peaks were observed with PLA
mixed with nano cellulose approximately at
100C. This is suggested to be due to
crystallization.
This means nano cellulose is effective as
nucleating agent.

combination of nano cellulose
composite and foaming technologyFoaming is useful technology
because plastic can be lighter and can be used as Insulating material.
The most known and famous foaming product is
foamed poly styrene.
Two major technology for foaming
(chemical foaming, physical foaming)
So far, chemical foaming have been often used as industrial use,
Although it is said that chemical foaming is not environmentally friendly
technology.
As physical foaming technology, chlorofluorocarbon or hydrocarbon gases have
been often used. However, these gas is said to be toxic, and furthermore, they can
destroy ozone layer. On top of that, these gases can be flammable and one of the
reason for global warming.
foamed poly styrene
We have been successfully making foamed plastic by
supercritical CO2, N2 gas foaming technology.
With our new foaming technology, foamed plastic such as foam
PP, PMMA, PLA, PS, ABS and other various types of foam
plastics can be made, because this technology can make pores
smaller than conventional method.
With this technology, plastic is expected to be even
stronger and lighter.
At the moment, even with 40% of CNF, mechanical strength
increase is 1.5 - 2.5 times, compared to the one without CNF.
With Supercritical CO2 Foaming Technology, could mechanical
strength be stronger even with lower CNF concentration??
