Summary: Biochar has been successfully used as a replacement for carbon black in rubber composites. By choosing the right feedstocks and developing effective treatment methods, biochar can improve reinforcement properties in rubber composites. This study created and characterized biochar from different feedstocks and found that nut shell biochars provide high reinforcement properties that meet or exceed those of carbon black. Slurry-based steam activation of biochar also improved the mechanical properties in the filled composite.

Summary: Worldwide, 45 million tons of waste cotton textiles are produced annually, and 75% of them are burned or buried, causing serious environmental pollution. This study demonstrates a method for directly preparing colored regenerated cellulose fibers (CRCFs) from dyed cotton textile waste (DCTW). The CRCFs have a tensile strength of 226 MPa, equivalent to commercial viscose fibers, and exhibit excellent color fastness and hydrophilicity. Additionally, CRCFs can be reprocessed into secondary CRCFs, which can still be woven into fabrics despite a slight reduction in tensile strength.

Summary: Beryllium is a rare element found in the Earth's crust, coal, and minerals. It is used in aerospace, electronics, and mechanical industries as an alloy with other metals. The main sources of emissions to the atmosphere are coal and fossil fuel combustion, as well as incineration of municipal solid waste. In the environment, most beryllium is sorbed to soil particles and sediments, with contamination occurring through atmospheric deposition on plants. Beryllium and its compounds are toxic, and the general public is exposed through inhalation and ingestion of contaminated food and water.

Summary: In this study, the interaction between microplastics and biochar during environmental aging was investigated. It was found that early-stage interactions of microplastics and biochar could promote the release of dissolved organic matter (DOM) from biochar, while their long-term interactions resulted in the sorption of hydrophobic and small molecules of microbial byproduct-like DOM. Early-stage interactions also promoted the sorption of organic contaminants, but this promotion was no longer observed after aging due to the influence of heterogeneous aggregation.

Summary: Developing biocomposites from waste paper and plastics can contribute to global sustainability goals and address environmental issues. This study demonstrates a practical method for producing waste PVC/paper biocomposites with excellent performance. The combination of PVC powder and paper floc is optimal in the PVC/paper (NaOH) 3:7 ratio, resulting in the best mechanical properties. Furthermore, as the proportion of PVC powder in the composite increases, the water absorption of the biocomposites generally decreases.
