- Lime Air Bag
"LimeAir Bag", a plastic bag containing about 25% limestone, has been adopted as a garbage bag used at the food factory of Warabeya Nichiyo Holdings.
TBM Co., Ltd., Ltd. (Headquarters: Chiyoda-ku, Tokyo, CEO: Nobuyoshi Yamasaki, hereinafter referred to as TBM)'s plastic bag "LimeAir Bag" containing about 25% limestone is used by Warabeya Nichiyo Holdings Co., Ltd. Headquarters: Shinjuku-ku, Tokyo, President: Hideo Tsuji, Warabeya Nichiyo Holdings) has been adopted for the garbage bags used in its food factories.
LimeAir Bags, which contain approximately 25% limestone, are lighter than standard polyethylene bags, and by switching from the polyethylene garbage bags that Warabeya Nichiyo Holdings previously used to LimeAir Bags, it is expected that the amount of petroleum-based plastics used will be reduced by approximately 28% annually, and greenhouse gas emissions, including CO₂, will be reduced by approximately 22% *1. Going forward, TBM will promote environmentally friendly measures at various factories, not just in the food industry, through the sale of LimeAir Bags.
*1 Estimated by TBM (procurement of raw materials to incineration). These values are not guaranteed values and may vary depending on manufacturing conditions.
Three features of LimeAir Bag
Feature 1: Reduces the amount of petroleum-based plastics used
Compared to polyethylene bags, LimeAir Bags can reduce the use of petroleum-based plastics by up to 34%.
Feature 2 Reduction of greenhouse gas emissions including CO2
Compared to polyethylene bags, the LimeAir Bag can reduce greenhouse gas emissions, including CO2, by up to 29% over the entire life cycle (raw material procurement - pellet manufacturing - molding - transportation - disposal [incineration]).
Feature 3 Achieved weight reduction with air gap control technology
By kneading and stretching polyethylene resin and limestone (calcium carbonate), air layers (voids) are created around the calcium carbonate grains. By controlling the air gap, the LimeAir Bag achieves a maximum weight reduction of about 10% compared to polyethylene bags.
