Bio-PET Resins

Eco-Friendly Resins of using Bio-Based Raw Materials

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.*

Product Characteristics

1. Reducing CO₂ emissions by 28%
2. Environmentally-friendly resin consisting of 30% bio-based raw material

Product Characteristics

1Reducing CO₂ emissions by 28%

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% (approximately 0.7kg per 1 kg of biomass PET) from the production process to consumption, compared to normal PET.

2Environmentally-friendly resin consisting of 30% bio-based raw material

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.

Major Applications

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.
