Due to the traditional papermaking using raw wood pulp, a large amount of wood is consumed, the ecology is destroyed, and serious pollution is caused. Therefore, 'urban papermaking' using waste paper bins has become the two major development trends of modern papermaking industry together with 'forestry-paper integration' of afforestation and papermaking integration. At the same time, urban papermaking also plays a role in absorbing urban garbage, embodying the spirit of 'urban production and urban consumption'.
