Amidst the global acceleration of plastic pollution control and the development of a circular economy, the disposal of used plastic crates is becoming a headache for many businesses and regions. These crates are widely used in industries like manufacturing and logistics, and their durability and lightweight nature mean they are in high demand. However, once worn and damaged, systematic solutions are often lacking. If carelessly piled or landfilled, they can remain difficult to degrade for decades, gradually releasing microplastics and harmful substances, causing long-term pollution to soil and water sources. Currently, many recycling channels are inefficient, difficult to sort, and contain high levels of impurities, resulting in a large number of used crates going unused, wasting resources and increasing the environmental burden.
