| Abstract:With the continuous advancement of the “dual carbon” strategy， the utilization of solid waste is increasingly emphasized. At present， the overall utilization rate of solid waste and added value of the products are relatively low. In recent years， the solid waste-based paper fillers have received widespread attention because the solid waste based paper fillers can not only alleviate environmental pollution issues but also substitute cellulose fiber raw materials， reduce paper production costs and improve paper properties to some extent. Therefore， using solid waste to prepare paper filler is undoubtedly an effective way to utilize solid waste comprehensively. This paper discussed the advantages and challenges of solid waste based-paper filler. The impacts of solid waste based-paper filler on the physical properties of paper were also analyzed based on preparation strategies and their physical and chemical properties. Finally， the development direction of solid waste based filler was also outlined. |
