Biomass Plastic Innovation by Rice Resin
ur strength is that we manufacture and sell two types of biomass plastics;
1) Biodegradable plastics called "Neoryza" that can return to nature, and 2) Non-biodegradable plastics called "Rice Resin" that has strength and durability. Our technology can upcycle regional and national crop wastes into raw materials for biomass resins.
Knowing the existence of rice wastes (rice scraps, out-of-spec rice, expired rice, rice damaged by typhoons and other disasters, etc.), which has become a social problem, we started our research and product development about 20 years ago. Rice Resin can be used to produce plastic products, and the resin contains 10 to 70% of rice as a raw material. Our Rice Resin & Neoryza will continue to contribute to resolving micro-plastics pollution, climate change, and decarbonization issues.
Our main product 'Rice Resin' is made from inedible rice which has excellent physical properties, and both domestic and International markets are featuring it's Up-cycling Plastic Innovation everywhere. (see Fig. 1 and 2)

Major Features and Advantages
Our business is characterized by a variety of features:
- Unlike polylactic acid and bio-polyethylene, which are produced after fermented bioethanol is generated, we produce biomass resins by kneading with polymer resins.
- Compact plant design is possible by using general-purpose machinery and equipment as the main equipment, instead of using large-scale chemical plant facilities made from sugarcane, corn, etc. as a metaphor.
- Local production for local consumption is possible because biomass from the region or country can be used as feedstock.
- The compactness of the plant and equipment used also makes it possible to accommodate small-lot production.
- The introduction of remote monitoring and operation systems such as IOT and DX is being actively promoted, making it easy to deploy in multiple regions.
- There is another reason for choosing rice as a raw material, and that is the size of the rice to be mixed with the resin. Unlike other biomass materials, rice can be harvested, threshed, and put directly into the mixer to be mixed with resin, saving much more energy than larger materials that need to be harvested, dried, and etc.

Unlike polylactic acid and bio-polyethylene, which are produced by first generating bio-ethanol, our products do not require large-scale chemical plant facilities because biomass plastic is produced by kneading.
Our products are designed using general-purpose machinery and equipment as the main equipment, and are compact in size with high adaptability to localization. In addition, local biomass can be utilized to produce biomass plastics for local consumption. In addition, remote monitoring and operation systems are actively being introduced, making it easy to expand the system to multiple regions.
Since there is no need for large-scale chemical blasting facilities, the basic production line installation cost is only 150-200 million yen. (This does not include land, buildings, or basic utility facilities.) The estimated production volume of Rice Resin is 1,000 tons per year.
The main production equipment is a continuous twin-screw extruder for plastic compounding, and the other ancillary equipment consists of general-purpose equipment for plastic molding and processing, so it does not include any very special equipment.
In terms of operation and management, each facility can be monitored remotely, making it possible to operate the plant even in cases where highly specialized personnel are not available at all times. Furthermore, waste materials can be recycled and recharged at a reduced cost, or they can be utilized as RPF (Refuse Paper and Plastic Fuel).
