Kewpie Pioneers Circular Economy with Recycled PET Bottles

In a significant stride towards sustainability, Kewpie Corporation, based in Shibuya, Tokyo, has made a remarkable development in using recycled materials. Working in collaboration with Nisshin Oil Group, Kewpie has successfully implemented a horizontal recycling process for oil-coated PET bottles, making it the first domestic instance of its kind. This innovative approach allows the reuse of recovered materials from oil-coated PET bottles in the creation of new PET bottles for four types of dressing, set to be launched in limited quantities by April 2026 in select stores.

Background and Challenges

Recycling oil-coated PET bottles has presented unique challenges in the past, mainly due to concerns about the residual oil affecting the quality of recycled materials during the cleaning process. As a result, a practical recycling system for these bottles has yet to be established socially. To address this issue, Kewpie and Nisshin Oil Group embarked on a collaborative project beginning in May 2024. Leveraging years of expertise dealing with oil, they conducted technical verifications and confirmed that the quality of containers produced from recycled oil-coated PET was satisfactory. This groundbreaking research was later published in a scientific paper, highlighting their advancements.

The project involved collecting oil-coated PET bottles generated at Kewpie and Nisshin Oil Group's manufacturing facilities, transforming them into recycled materials. These materials are then used in producing new PET bottles, ensuring that they can be returned to market as products, marking a vital step in effective resource circulation.

Featured Products

The four products that will be sold in limited quantities, starting in April 2026, are:
1. Kewpie Deep Roasted Sesame Dressing
2. Kewpie Caesar Salad Dressing
3. Kewpie French Dressing (White)
4. Kewpie Coleslaw Dressing

Each dressing will come in a 180ml bottle, with a reference retail price and shelf life consistent with their standard products.

Future Prospects

This initiative not only sets a precedent for the recycling of oil-coated PET bottles but also paves the way for further possibilities in plastic resource circulation. Kewpie aims to expand its horizontal recycling capabilities while exploring additional applications for recycled materials. The ultimate goal is to establish an optimal resource circulation scheme, contributing significantly towards sustainability.

Kewpie’s commitment to a circular economy is encapsulated in its Environmental Vision 2050, which emphasizes building a society where oil-coated PET bottles can once again foster resource utility. With this effort, Kewpie is taking important steps towards the construction of a circular economy and a sustainable future.
