RENU PROJECT

"From fiber to fiber" with color
and quality as desired

RENU aims to realize a circular economy by effectively utilizing unwanted clothing that has been disposed of, as well as leftover fabric and shredded fabric (dough) produced during production. RENU will contribute to reducing the use of petroleum and other fossil resources.Waste fibers are recycled through chemical processes such as decomposition and repolymerization to provide products of comparable quality to regular products.

RENU aims to realize a circular economy "Take (to mine for resources,)", "Make (Make it.)" and "Waste (throw away)" by effectively utilizing fiber that has been disposed of without being used in the conventional linear economy. With the participation of producers, brands and consumers, you can draw circular system as following illustration.

We want many people involved in the fashion industry to participate in this project, so we provide RENU in various forms such as yarns, fabric and products so that they can participate from any stage of the supply chain. Together with our partners around the world, we will build a new supply chain for the future.

SUSTAINABILITY

Comparing with the use of petroleum-derived regular polyester, using RENU polyester gives better impact on planet.
Here, you can see the positive environmental impact of RENU compared to virgin polyester as below.
This date is based on LCA(Life Cycle Assessment) report of RENU chips and virgin polyester chip.

In general, recycled polyester is made from PET bottles, which are then melted to form yarns. RENU, on the other hand, uses unneeded clothing, leftovers from production, and shredded materials (dough) as raw materials, and goes through chemical processes such as disassembly and repolymerization. As a result, all the colors and miscellaneous materials contained in the raw materials are removed, making it possible to produce polyester that is of comparable quality to petroleum-derived polyester.

Conventional recycling technologies, such as those used to recycle PET bottles, have had a problem in that it is difficult to completely remove the color that adheres to them, resulting in subtle color differences between lots. RENU's recycling technology is called “chemical recycling methods”, which has been overcome and the recycled fiber has the same stable dyeability as petroleum-derived polyester. No matter what color of clothing or fabric you recycle, you can get the colors you want.

The world is flooded with a wide variety of high quality and functional clothing. The demand for fiber as a raw material is increasing day by day, and products with added value such as fine count, high strength, special cross section and luster are required. Conventional polyester recycled from PET bottles was limited in quality because the quality of the raw materials depended on it. However, RENU's technology can recycle any raw material into fibers of stable quality, making it possible to express the features and functions essential to producing high-quality clothing.
