Mixing Technology of Old Paper and Plastics - Recycling of Old Paper -
A key point is to uniformly disperse into the melted plastics! Introducing a technology realized using a twin-screw extruder.
Recycled paper is mainly referred to as recycled paper in the context of old paper recycling, but there are other uses for old paper, such as cushioning materials and packaging made by blending old paper with plastics, as well as various containers. The blending of old paper and plastics is one of the technologies that should be established urgently from an environmental protection perspective. In the recycling of old paper using an extruder, the various forms of old paper and their low bulk density result in poor feedability into the extruder. Additionally, since paper is fibrous, it tends to tangle easily, making it a significant challenge to uniformly disperse it into the molten plastics. We have achieved the blending and pelletizing of old paper and plastics using our twin-screw extruder 'TEX'. 【Mixing Technology】 ■ Stability of raw material feed ■ Dispersion of old paper ■ Low-temperature extrusion ■ Devolatilization *For more details, please refer to the PDF materials or feel free to contact us.

We will provide the technology of the twin-screw extruder 'TEX' to the chemical recycling demonstration facility.
We are pleased to announce that our company will provide continuous decomposition technology used for chemical recycling to Sumitomo Chemical Co., Ltd. This technology continuously recovers MMA (methyl methacrylate) monomer from used acrylic resin (PMMA) using a twin-screw kneading extruder from the 'TEX Series'. The 'TEX Series' twin-screw kneading extruder is expected to be applied not only for thermal recycling and material recycling purposes but also for chemical recycling applications. To meet societal needs for recycling technology, we plan to establish a chemical recycling center within our Hiroshima manufacturing facility in 2022. Our group will continue to work on developing products that reduce environmental impact and aims to be a company that contributes to the realization and development of a sustainable society.

Development of a new resin composite with a high content of wood biomass - Reducing plastic use and greenhouse gas emissions -
Our company, in collaboration with Nippon Paper Industries Co., Ltd., has developed a resin composite material (Trefa Bio Composite) that contains a high proportion of wood-based biomass as a raw material. This new composite material can reduce plastic usage by more than 50% and also contributes to the reduction of greenhouse gas emissions. In composite materials made from wood-based biomass such as wood powder and pulp, conventional products have faced challenges in heat resistance and moldability. The newly developed Trefa Bio Composite utilizes Nippon Paper's established Trefaction technology for new biomass solid fuels, which imparts heat resistance, grindability, and hydrophobicity to the wood-based biomass. By using the kneading technology of the twin-screw extruder 'TEX' to incorporate this sustainable wood-based biomass material into the resin at a high ratio, we have created a new Trefa Bio Composite that excels in heat resistance and moldability compared to conventional products. This Trefa Bio Composite and cellulose bio composite will be exhibited at Nippon Paper's booth at "TOKYO PACK 2021." Moving forward, our company will continue to enhance the kneading technology of 'TEX' and advance the development of better products.
