The company aims forlocal pro-duction for local consumption, where rice can be produced, manufactured, and used in various regions of Japan, and plans to establish 10 production sites in Japan by 2025. The company is also working on a project to apply its expertise in rice resin production to unused biomass other than rice, and is also developing the conversion of cof-fee grounds and other materials into resin. Fukushima said, “We have re-ceived requests to use food residues, and it is possible to convert them into resin. However, we need companies that will adopt the resin as an outlet,” he called for.In addition, he introduced Neory-za, a rice-derived biodegradable plas-tic that it plans to manufacture and sell overseas, as well as resource rice production using fallow rice paddies in response to declining demand for edi-ble rice. For Neoryza, a local subsidiary was established in Bangkok, Thailand, and production and sales were com-missioned to Mitsui & Co. Plastics Ltd., Hitachi High-Tech Corporation, etc. Preliminary sales will begin in Asia in the summer of 2022, with sales in the Japanese market targeted for 2025. The company has been producing rice Source: Presentation materials for the 85th Symposium of the Society of Packaging Science & Technology, JAPANas a resource since September 2020 in Namie-cho, Fukushima Prefecture, which was hit by the Great East Japan Earthquake in 2011, and in 2022 it plans to expand the scale of production and try ratooning, in which rice can be plant-ed and harvested twice in one year.Plastic packaging and mass balance approachMr. Takashi Hanaichi of FUTAMURA CHEMICAL CO., LTD. spoke on en-vironmental issues sur-rounding plas-tic packaging and the mass balance approach.On June 29, 2021, FUTAMURA CHEMICAL announced that it is pre-paring to obtain ISCC (International Sustainability and Carbon Certifica-tion) certification for its biomass OPP film using the mass balance method. Mr. Hanaichi explains the mass bal-ance method as follows.“The mass balance method” is a technique whereby when raw materials with certain characteristics are mixed with those that do not, an allocation of those characteristics to a portion of the product is made in proportion to the amount of input. It has been used for biofuels, electricity, palm oil, and paper certification. The background to the application of this method to plas-tics is the recent spread of methods for mixing petrochemical-derived raw materials with waste plastic-derived raw materials and biomass-derived raw materials, and the emergence of manufacturing processes that do not require expensive capital investment in dedicated plants and other equipment.However, plastics produced by this method have a low percentage of bio-mass components and waste plastics, so the mass balance method, which al-lows “one-sided” inclusion of biomass and recycled material blends to in-crease added value, began to be com-mercialized in Europe around 2014. Originally, this method was based on the concept of calculating the recycling rate for chemical recycling, or material balance, and biomass certification was added to it as a set to make it easier to handle.Four advantages of the mass bal-ance method were mentioned.(1) Resins such as PP, which could not be converted to biomass before, can now be converted to biomass.(2) Even if the actual mixing ratio is low, the value can be increased by making allocations, thus avoiding any impact on performance and quality.(3) Material balance of chemical re-cycling that could not be proven can be verified.(4) In the recycling type chemical recycling where waste plastic is con-verted to oil and cracked together with petroleum-derived naphtha, it is not possible to verify the recycled materi-Biomass resin made from inedible rice27
