By using biomass plastic to constitute a percentage of the material used to produce a refill pouch, the amount of petroleum-derived plastic used has been reduced by about 9 to 10%. To reduce CO₂ emissions and prevent food loss, waste molasses produced as a by-product of sugar production from sugar cane have been applied as a raw material for biomass plastic. We have also reconsidered the structure of layers and improved the ease of opening the pouch compared with existing products.
