This　paper　proposes　a　method　for　the　short-process　recovery　and　reuse　of　rare　earth　secondary　resources.　Low-value　rare　earth　polishing　powder　waste　(WP),　trichromatic　phosphor　waste　(WT),　NdFeB　permanent　magnetic　waste　(WN),　and　SmCo　permanent　magnetic　waste　(WS)　were　used　as　the　raw　materials.　Based　on　the　concept　of　combinatorial　chemistry,　energy-efficient　cool　pigments　and　environmental　remediation　materials　were　synthesized　by　a　solid-phase　method.　The　results　showed　that　the　synthesized　materials　had　fluorite-type　and　garnet-type　structures.　In　terms　of　cool　pigments,　doping　with　different　rare　earth　permanent　magnets　can　enrich　the　color　(including　yellow,　green,　brown,　gray,　and　blue)　and　cause　fluctuations　in　the　near-infrared　(NIR)　reflectance　(59.05-　99.54　%)　and　NIR　solar　reflectance　(55.32-　95.64　%).　Yellow　fluorite-type　pigments　(WP:　WT　=　1:1)　have　the　highest　NIR　reflectance　(R　=　99.54　%),　while　brown　fluorite-type　pigments　(WP:　WN　=　1:0.1)　and　blue　garnet-type　pigments　(WP:WS　=　1:0.1)　have　relatively　high　NIR　reflectance,　88.18　%　and　59.30　%,　respectively.　The　synthesized　pigments　possessed　better　chemical　stabilities　and　thermal　insulation　performance.　In　terms　of　environmental　remediation　materials,　the　adsorption　capacities　of　fluorite-type　materials　for　F-　and　PO43-　can　reach　84.03　mg/g　and　85.3　mg/g,　respectively.　In　summary,　materials　synthesized　from　rare　earth　waste　exhibit　excellent　potential　for　use　in　energy-efficient　wastewater　treatment　and　promote　the　sustainable　utilization　of　secondary　rare　earth　resources.
