By linking the achievements of WEEE recycling to the policy to promote carbon neutrality, the Fund would compensate for the associated fee, thereby facilitating sustainable recycling. To test the feasibility of this strategy, we have assessed GHG emission reduction levels associated with WEEE recycling based on archival data analysis and field research. The results show that the GHG reduction related to WEEE recycling in Sichuan Province is 160,279.152 tCO_2eq. and 8.36 million tCO_2eq in China in 2021. But this amount significantly underestimates the potential benefits due to methodology limitations. It is assumed a reformed approach that can increase the estimated GHG reductions by 42% (to 11.85 million tCO_2eq).

The development of a cost-effective and efficient technique for CR degradation is essential. In this study, mesoporous BiZnO₃/g-C₃N₄ nanocomposites were synthesized via thermal decomposition for the degradation of CR dye under sunshine. Powder X-ray diffraction analysis revealed the formation of pure phases of the materials, with the average crystallite size of BiZnO₃ being 20.89 nm. The Fourier transform infrared spectrum shows the presence of different functional group such as Bi–O, Zn–O, C–N, and C═N. The surface morphology of the sample showed BiZnO₃ nanorods (100–300 nm) embedded in g-C₃N₄ sheets. The high-resolution transmission electron microscopy image showed the formation of lattice fringes with an interplanar spacing of 0.200 nm, corresponding to the (431) plane of BiZnO₃. The specific surface areas of mesoporous BiZnO₃, g-C₃N₄, and BiZnO₃/g-C_₃N₄ were 14.02, 17.30, and 45.82 m² g^–1, respectively. The direct band gaps of BiZnO₃, g-C₃N₄, and BiZnO₃/g-C₃N₄ were found to be 3.37, 2.90, and 3.43 eV, respectively. The BiZnO₃/g-C₃N₄ nanocomposite exhibited 99.79% removal of CR dye within 1 h and followed a first-order reaction kinetic model, with a rate constant of 0.0470 min^–1. The degradation efficiency decreased with an increase in the pH of the solution, with the maximum efficiency observed at pH 2. The presence of coexisting anions affected the degradation efficiency in the following order: IO₃^– &gt; Cl^– &gt; Br^– &gt; NO₃^– &gt; PO₄^3–. Scavenger experiments indicated that ^•OH and h⁺ are the active species involved in CR degradation. Furthermore, after six recycling runs, the catalyst performance showed only a 6% decrease, indicating the stability of the BiZnO₃/g-C₃N₄ nanocomposite.

In this study, photocurable resins for digital light processing (DLP) 3D printing are developed by simply blending biomass-derived epoxidized soybean oil, lipoic acid, and isobornyl acrylate at 110 °C with a catalyst. The printing speed and thermomechanical properties of the resins can be easily tuned by adjusting their compositions.
