FENC utilizes used coffee grounds collected from convenience stores as the raw material during yarn spinning for the downstream processing of non-woven dry wipes and facial masks. This innovation has set a precedent in Taiwan for the large-scale application of used coffee grounds in skin care and sanitary products, which were unveiled at the 2024 Asia Nonwovens Exhibition and Conference.

Each year, approximately 50,000 metric tons of coffee grounds are generated in Taiwan. FENC carbonizes the coffee grounds into activated charcoal using its existing production facilities, which delivers a production scale higher than that using extraction method in Taiwan. The charcoal boasts a deodorizing effect that has been third-party verified. Being a carbon-fixing product, it cuts 3 kgCO2e of carbon emissions per kilogram. The transformation has helped convenience stores turn waste coffee grounds into sustainable products.
