We use a centralized system as the business model for recycling used diapers: Disinfection, cleaning, dewatering and drainage are all done using our ergonomic equipment in each long-term care facility. This equipment causes no foul odors and dewatered diapers are easily shippable to be recycled at the Center. In long-term care facilities, the collection and processing device necessitates an ergonomic design, so the nurses can easily pull the collection bucket after diaper collection and push it into the laundry machine with the Gullwing opening. After appropriate pretreatment in a closed system, the inside baskets are stacked outside in a pile for further shipment offsite. In the central recycling center, the used diapers are first shredded, and then natural ingredients are added to stratify the salts and fiber mixture into different layers. The separated PE, fiber and salts can be reused to produce Eco-value-added products.
