ZERO WASTE STARTS WITH LAUNDRY: SHINING BRIGHTER WITHOUT ADDING TO EARTH’S BURDEN

Picupi International Co., Ltd. EcoCal® Laundry Detergent
Picupi International Co. Ltd. (Picupi) produces zero waste laundry detergent. In 2022, it introduced the
"Shell Calcium Oxide" laundry detergent powder (patent number: Invention I742838) to launch a rescue mission
and transform the journey of laundry! With the production of shellfish in Taiwan's coastal aquaculture industry, Picupi uses discarded freshwater cultured golden clam shells from the Lichuan fishery in Hualien, Taiwan to produce food-grade "shell calcium powder" through a patented process involving temperatures exceeding 1,000 degrees Celsius. This material forms the basis for a series of disinfectant cleaning products. Approximately 3,000 metric tons of shells are recycled annually, contributing to a reduction of 768 metric tons of CO2e emissions.
The ingredients of shell calcium powder have obtained ECOCERT natural certification from France and
certification from the Natural Products Association in the United States. They are simply mixed with water
to produce reactive oxygen species (ROS), enabling functions, such as sterilization, dirt removal, grease
breakdown, impurity adsorption, chemical degradation, and reduction of pesticide residues. Picupi also aims to achieve a full-circle design, ensuring product traceability and 100% recyclability, while using recycled paper for bottle packaging. After use, consumers can separate the paper packaging for individual entry into paper and plastic recycling systems. Starting from December 2023, initiatives like bottle recycling (Re-bottle) or refilling at physical stores (Refill) have been promoted, making it the best solution combining low-carbon manufacturing and green consumption.
Shell Calcium Oxide laundry detergent powder has since evolved to its 2.0 stage, incorporating more environmentally friendly materials or designs in its products, such as the newly launched packaging,
further reducing carbon emissions by 24.8%.
