Leading the Industry as First to Offer Bio-PET Resins
In 2010, Iwatani began to develop biomass PET resin. Iwatani offers integrated solutions from PET resin production to processing of final products, taking advantage of the supply system and supply chain we acquired over the years.
A variety of raw materials support every aspect of our daily lives, such as steel, glass, and ceramics. In a country like Japan with few natural resources, a stable supply of high-quality raw materials is vital for industrial activities. We select optimal raw materials from domestic and foreign sources to ensure a stable supply of materials, including mineral sands, raw materials for refractories, rare earth elements, and inorganic chemicals that meet the specific requirements from our customers. We are also actively involved in the development of new materials.
We cover materials and processed products on a global scale, with a special focus on stainless steel, aluminum, and high alloy steels. Via operating companies both in Japan and overseas, we provide materials and products to the growth sector, including the automotive, air conditioning, electronic, medical, and environmental industries. We contribute to society by offering high performance materials and processed products to move the world closer to achieving the SDGs and establishing a decarbonized society.
Drawing on our global network to offer optimal solutions
Iwatani maintains a procurement network and processing sites both in Japan and overseas and has established an optimized supply chain to supply products to meet the diverse requirements of our customers. Selling high performance materials and processed products also helps reduce CO2 emissions at the stage of product use, an important step in achieving the SDGs and establishing a decarbonized society.
Iwatani offers state-of-the-art display devices and technologies, including rechargeable batteries, organic EL displays, and vehicle displays, key elements in achieving a decarbonized society, as well as a wide range of materials used in devices essential to our everyday lives. Examples include the semiconductors and electronic components at the heart of autonomous driving and 5G high-speed communications. Iwatani also supports technological innovation in electronics in terms of basic materials by adding new value to resins, ceramics, and metals. Iwatani takes advantage of its manufacturing and processing capabilities in China, Southeast Asia, and a growing range of regions worldwide.
New Business Development Department specializes in development of and investment in new businesses that lie among Materials Division and have yet to be tapped.Fully utilizing overseas networks, this department primarily sets up biomass fuels and other environmental businesses, investigates overseas investment opportunities and carries out research and development into next-generation materials through cooperation between industrial enterprises and universities.
Bio-PET resins are manufactured using 30% of bio-based raw materials of monoethylene glycol refined from molasses, a byproduct of sugar cane processing. Iwatani started selling bio-PET resin in 2010 and currently has No. 1 market share in Japan.*
*Based on Iwatani data as of December 2021 (30 thousand tons handled in 2021)
In order to promote sales of sustainability-conscious raw materials, Iwatani conducts research based on Life Cycle Assessment (LCA), which quantitatively evaluates the impact of raw materials on the ecosystem and the environment from the development stage. In 2011, DNP, Tokyo City University, and Iwatani conducted a joint research and survey on LCA of bio-PET resin. As a result, we found that biomass PET can reduce CO2 emission by 28% (1.7kg per 1 kg of biomass PET) from the production process to consumption, compared to normal PET.
Biomass PET resin is made from biomass MEG refined from , a byproduct of sugar cane processing. This allows approximately 30% of PET resin to be bio-based.
Bio-PET resin has virtually identical physical properties to petrochemical-based PET resin, making it suitable for a wide range of applications through simple replacement of currently used PET resin.
We are working on proposing a new type of concrete reinforcement. This new reinforcing material is a resin fiber, which reduces labor and construction time compared to traditional mesh reinforcement, reduces costs, and solves the problems of traditional mesh reinforcement (Cracks, Rust, Chemical Resistance, Breakage of Mixers and Pumps, etc.).
In particular, unlike iron wire, it is highly evaluated as a reinforcing material that does not rust and is used for waterproof concrete.
When using the product, our professional engineers will support the design, formulation, and usage of each product so that you do not have to worry about it.
Resin Fiber Concrete Reinforcement
1-2 days needed to complete preparation, including compaction, laying plastic sheet, measuring, cutting, carrying and install steel reinforcement or placing wire mesh, prepare steel chairs and spacer blocks, install formwork, level marking, inspection, and correction if needed.
In the past, inferior recycled resins were used just to make them cheaper. However, in recent years, when global warming has become more prominent, countries and companies are promoting the adoption of recycled resins with the aim of reducing greenhouse gas emissions and changing from petroleum-derived resins.
There is a demand for a stable supply of recycled resin that can be replaced with resin. We are committed to supply recycled resin to meet this need.

A byproduct produced during the production of palm oil, PKS (palm kernel shells) is used as a fuel in biomass power plants. Iwatani handles PKS produced in Indonesia and Malaysia.
1Stable Long-Term Supply Arrangements
To ensure stable PKS supply, Iwatani maintains long-term relationship with suppliers who operates Crude Palm Oils Mills.
2Flexible Delivery Schedules
Iwatani procures PKS from multiple shipping sites in Indonesia and Malaysia to allow the flexible delivery schedules.
3Strict Quality Control
PKS which moisture and foreign material are controlled will be shipped from Indonesia and Malaysia. Upon importation, we conduct in-house quality analysis at the Iwatani R&D Center, checking constituents, calorific value, specific gravity, and other parameters.
PKS, a carbon-neutral fuel, is derived from the fruit kernel of palm trees, which absorb CO2 when they grow. This offsets the CO2 emitted during combustion, resulting in a net zero impact on atmospheric CO2 levels.
Malaysia and Indonesia grow enormous palm trees, and the harvested palm fruits are mainly used for palm oil and cosmetics production. Conventionally, the remnants of these processes were simply disposed, However those are used as biomass fuel in our own day.
Iwatani has achieved GGL (Green Gold Label) certification. Iwatani’s declaration
Iwatani also handles a wide range of products such as silica sand for use in power generation boilers to assist in the combustion of biomass fuels.
Wood pellet is a biomass fuel produced from thinned lumbers generated at forest and from wood wastes generated at sawmills. Iwatani handles FSC (Forest Stewardship Council) and PEFC certified wood pellets produced primarily in Southeast Asia including Vietnam. Iwatani implements a voluntary code of conduct based on guidelines established by the Japanese Forestry Agency (guideline of certifying woody biomass for electric use).
Voluntary Code of Conduct
As a carbon neutral fuel, wood pellets do not affect emissions of CO2 into the atmosphere. Wood pellets are derived from thinned lumbers, wood wastes and sawdust generated from sawmills, however the originating trees absorb CO2 during their growth cycle, offsetting the CO2 emitted when they are burned. Overall, they have a zero effect on atmospheric CO2 levels. Iwatani works with multiple leading suppliers who operate stable production and quality control systems and offer enough supply capabilities to ensure a stable long-term supply of high quality wood pellets.
Iwatani offers FSC and PEFC certified wood pellets. We are also a certified supplier of woody biomass used for power generation, a requirement for supplying to biomass power plants in Japan.
Iwatani also handles a broad range of other products, including the silica sand feeded to power generation boilers to assist combustion of biomass fuel. Iwatani is working on the commercial development of torrefied wood pellets*, a promising alternative to coal.
