The environmental impact of cookie trays is a key focus at Zhejiang Hengiiang Plastic Co., Ltd., where sustainable practices are embedded in the production lifecycle. The company prioritizes the use of recyclable PET and PP, and explores options like rPET (recycled PET) to reduce virgin plastic consumption. In manufacturing, energy-efficient machines and closed-loop water systems in the clean workshop minimize resource use. For instance, a client in the eco-friendly sector requested cookie trays with a lower carbon footprint, leading Hengiiang to develop a tray using 30% recycled content without affecting performance. Applications in circular economy models include take-back programs where used trays are collected and recycled into new products. The laboratory conducts carbon footprint analyses and encourages clients to participate in sustainability certifications. The technical managers research biodegradable additives, though PET and PP remain preferred for their balance of sustainability and functionality. With a building area of 13,000 m², the company allocates space for recycling operations, and the storage area manages segregated waste streams. A case study showed that a retailer using Hengiiang's green trays saw improved brand perception among environmentally conscious consumers. This commitment not only meets regulatory requirements but also aligns with global trends toward responsible packaging.
