Asics, a Japanese sporting goods company, has announced the launching of its most eco-friendly footwear line to date, which is made from five tonnes of recycled textile waste, equivalent to 25,000 t-shirts.

The Earth Day Pack collection, which includes running, court, and sport style sneaker lines as well as an assortment of clothing, was developed using a circular manufacturing approach that was able to keep textile waste out of landfills.

In addition to recycled materials, the company claimed to have used a resource-saving technique known as solution dyeing, which cuts CO2 pollution by 45% while reducing water use by 33% during the dyeing process.

In a release, President, and COO at Asics, Yasuhito Hirota said that they're committed to helping to create a circular economy that reduces CO2 emissions and keeps global warming below 1.5°C. Just 1% of the world's garment waste is upcycled, while over 70% of clothing is disposed of in landfills or incinerators. He added that they will contribute to the development of a circular economy and offset the effects of climate change by continuing to reinvent the production process in all of our product categories.

By helping to rethink the manufacturing process in all of our commodity types, we will contribute to the growth of a circular economy and mitigate the impacts of climate change.

All of the footwear in the collection has a sunflower emblem and seed graphics, symbolizing the brand's dedication to planting seeds for a prosperous world and protecting the environment, according to the company. The two arrows in the emblem's middle reflect the company's desire to contribute to the development of a circular economy.
