The platform's own employees act as recyclers. When users place an order, the platform dispatches the order or grabs the order nearby. The recycler receives the order and comes to collect it. The type and weight of the waste are checked based on the actual waste, and the price is generated based on the system pricing. After both parties confirm, the recycling coins are paid to Users and recyclers will send the corresponding amount of waste received to the platform offline. The recycling coins obtained by the user can apply for withdrawal or exchange for goods in the exchange city.
