Company Name: Pulcra Specialty (Shanghai) Co., Ltd.
Project Name: Pellutax White Tan 85
Award Category: Innovation Sustainable Product
Product / Service Introduction
Trial production of the new product named Pellutax® White Tan 85 kicked off in September 2022. It has now been marketed and accepted by customers, with expected sales quantity reaching more than 100 tons annually.
It breaks through the technical bottleneck of the original zeolite tanning system by hybridizing zeolite and organic molecules, which is the first of this kind leading in the Chinese market. It shows excellent application properties, such as better softness and flexibility, high shrinking temperature, high degree of whiteness, good storage stability, non-yellowing, and perfect shaving performance.
Furthermore, the preparation process does not use formaldehyde or heavy metals as raw materials. As compared to traditional chrome leather, Pellutax® White Tan 85 demonstrated enhanced biodegradability. Shavings can be used as fertilizer to re-enter the ecological system.
Explanation of Circular Economy Practice
Pellutax® White Tan 85 is an environmentally friendly tanning agent based on naturally modified zeolite. It is primarily used in the tanning and re-tanning processes of leather and fur processing. It breaks through the technical bottleneck of the original zeolite tanning system by hybridizing zeolite and organic molecules, which is the first of this kind in the market. This product exhibits a remarkably strong binding capacity with collagen fibers, endowing leather with excellent fullness and exceptional tear resistance. This result is achieved by the R&D China team of Pulcra, Pellutax® White Tan 85 is not only the newly innovative products inside of the group, but also leads the competitive position in leather industry and market.
Pellutax® White Tan 85 is eco-friendly and free from formaldehyde and harmful heavy metals. It achieves zero presence of chromium and phosphorus, and it is also odorless. Therefore, it holds significant ecological and environmental value for clean leather production.
Simultaneously, during the application of the Pulcra Zeolite Tanning Agent, it enhances the material's absorption, reducing the overall usage of tanning agents in the process. It results in higher BOD/COD of tanning wastewater > 0.5, thus subsequently decreasing the chemical oxygen demand in wastewater. This not only lessens the demand for high-temperature and high-pressure treatments but also reduces carbon emissions in the leather industry.
Moreover, in light of public research results on zeolite, the shavings of Pellutax® White Tan 85, due to the absence of heavy atom, can be used as a nitrogen fertilizer. This obviously closes an ecological loop in circular economy.
