| Abstract: |
| The producing of huge amount of deinking sludge is currently one of the important environmental problems faced by waste paper mills. The reasonable utilization of deinking sludge is an effective way to solve the current contradictions. The basic properties of deinking sludge， including the main components， metal ion content， and organic pollutants of deinking sludge produced from different pulping process using waste paper as raw material were summarized. Based on the relative research findings at home and abroad， the latest research progress and application prospect of resource utilization for deinking sludge in biochar， bio-oil， organic and inorganic substance recovery， composting and anaerobic digestion， nutrition substrate and biocomposite materials were reviewed as well. |
