Transforming Eggshell Waste into Eco-Friendly Sanitaryware Through Circular Economy Innovation
Siam Sanitary Ware Co., Ltd. (COTTO), the leading brand in sanitaryware and surface decoration materials in ASEAN, has entered into a Memorandum of Understanding (MOU) with Charoen Pokphand Foods Public Company Limited (CPF). This partnership aims to repurpose byproducts food industry, with a focus on eggshell waste, into sustainable, eco-conscious sanitaryware products, aligning with both organizations’ commitments to the Circular Economy and their shared Net Zero goals.
This collaboration marks a powerful synergy between two of Thailand’s key industries: the food sector and the construction materials industry. Under this agreement, CPF will supply eggshell waste from its hatchery in Kaeng Khoi District, Saraburi Province, to be repurposed by COTTO in its sanitaryware production. This initiative marks a significant step forward in advancing Circular Economy practices within Thailand’s industrial ecosystem.
Mr. Thanongchai Asawinchaichote, Managing Director of Siam Sanitary Ware Co., Ltd. (COTTO), stated “COTTO is committed to developing innovations for sustainable living. One of our key projects focuses on replacing limestone with eggshells in the glaze production process for sanitaryware. This approach not only reduces the consumption of natural resources but also significantly lowers carbon emissions during manufacturing. We are delighted to welcome CPF as a strategic partner in providing bio/organic waste material. This collaboration marks the beginning of a new value chain—one where biological waste is given a renewed purpose that benefits both consumers and the environment.”
COTTO has already filed a patent for this innovative use of eggshells in ceramic glaze production, and the application is currently under review.
Mr. Panuwat Niamprem, Executive Vice President of CPF's Integrated Broiler and Duck Business, commented “At CPF, we operate under the concept of Sustainovation, sustainable innovation, to reach our Net Zero greenhouse gas emission goal. By adopting Circular Economy and Waste to Value strategies, we ensure that biological byproducts, such as eggshells from our hatcheries, are repurposed effectively. Our collaboration with COTTO is a strong example of unlocking value across the supply chain, optimizing resource usage, and enabling true circularity. This initiative not only helps reduce the need for landfill disposal but also contributes to lower CO₂ emissions.”
This partnership goes beyond a strategic business alliance. It represents a shared commitment to bringing the Circular Economy to life in a tangible way, balancing business growth with environmental stewardship and sustainable development in Thailand.
Both COTTO and CPF continue to lead with purpose, integrating innovation and sustainability to enhance quality of life while reducing industrial waste, minimizing environmental impact, and promoting the use of renewable energy in their operations.
