In recent years, daily life has been made much more convenient thanks to the growth of express delivery services. However, we should also think about the pressure express delivery industry creates on the environment. Large amounts of delivery packages mean high consumption of resources and that is why we need a more effective system to increase reusability and recycling. Through cooperation with express delivery companies and local communities in Haikou, reusable packing became widely used and accepted. We are working together to find ways and knowledge to reduce plastic pollution in the express delivery sector.
