and the eco-friendliness of biomass
TOMOEGAWA's Approach to a Circular Economy
Reducing Environmental Impact through Carbon Neutrality
TOMOEGAWA was established in 1914 as a paper manufacturer.
Having always used wood-derived materials,
it was only natural that we would ask ourselves how we could make
more environmentally friendly products. Our concern for the environment led us to create a technology
for homogeneously dispersing cellulose fiber in petroleum-derived resin.
Forests absorb CO2 and release O2 as part of their growth process. If properly managed and cared for, they become a sustainable resource.
Our GREEN CHIP CMF contains 55% wood-derived cellulose fiber, significantly reducing the use of petroleum-derived plastics.
Added Value from Our Cellulose Fiber Formula
Reduced CO2 emissions throughout the process from resin manufacturing to incineration (compared to petroleum-derived plastics)
During the process from resin manufacturing to incineration, the CO2 emissions of GREEN CHIP CMF, containing 55% cellulose fiber, are expected to be reduced by approximately 35%*1 compared with petroleum-derived ABS resin and by approximately 20%*2 compared with petroleum-derived PP resin.

Building a Circular Economy through Recycling
GREEN CHIP CMF is a material that can be recycled through material recycling.
As part of our in-house testing, we evaluated test pieces that had been crushed and molded five times. Test results showed that the attenuation (damping) rate was superior to that of glass fiber compounds.*3

GREEN CHIP CMF with Excellent Recyclability
GREEN CHIP CMF achieves superior recyclability compared to glass fiber-reinforced PP resin
- GREEN CHIP CMF LB55 is a product containing 55% cellulose fiber.
- The data are measurements, not guaranteed values.
Additional Role of Reinforcing Agent
Cellulose fiber also acts as a reinforcing material.
Tensile strength, flexural strength, flexural modulus and heat resistance (load deflection temperature) are improved compared with unreinforced polypropylene resin (PP resin).
This makes it possible to make molded products thinner and, therefore, lighter, too.

As a modifier for recycled resin
There are concerns about the decline in the physical properties of recycled resin. By adding GREEN CHIP CMF as a modifier, the physical properties can be improved, contributing to an increase in the use of recycled resin.
Increasing the addition of GREEN CHIP CMF further improves strength, flexural modulus, and load deflection temperature.

Improved Physical Properties of Recycled PP Resin with GREEN CHIP CMF
By adding of 10% to 90% GREEN CHIP CMF LB55 (containing 55% cellulose fiber) to recycled PP resin
- The data are measurements, not guaranteed values.
- Recycled PP is sourced from materials collected through Japan’s Container and Packaging Recycling System
- GREEN CHIP CMF is a product containing 55% cellulose fiber.
High MFR (Melt Flow Rate) for Easy Molding
No need to replace currently used molds
GREEN CHIP CMF delivers excellent moldability. Despite containing a high cellulose fiber content of 55%, it offers fluidity comparable to polypropylene.
This allows it to be adopted as a drop‑in alternative to petroleum‑based plastics using current molds. In addition, it exhibits minimal molding shrinkage and provides outstanding dimensional stability.

Comparison of Fluidity of Wood-Derived Fiber Compounded Resins
GREEN CHIP CMF features superior fluidity among wood-derived fiber-compounded resins through proprietary technologies
- The products of Companies A, B, and C use cellulose nanofiber and wood flour rather than cellulose microfibers, and thus differ in material composition. This difference may also affect the MFR values.
- The numerical technical data for Companies A, B, and C is transcribed from information published on each company's official website. With regards to Company A, the detailed conditions for testing methods have not been disclosed, and it is possible that testing methods different from ours were used.
Designability that Spurs Creativity
Boasting a high degree of designability that allows the creation of unique textures depending on molding conditions,
and being compatible with color processing, GREEN CHIP CMF makes it possible to create patterns and textures
that are not possible with conventional polypropylene resins.
Moreover, while it is generally difficult to print on olefin resins, GREEN CHIP CMF can be directly printed onto finished products.
- Flexible coloring and delicate hues
- Thin wall molding also possible
- Unique textures can be created on the surface of products depending on molding conditions
- Printing on the surface of molded products is also possible.
