Researchers have developed an environmentally friendly hydrogel adsorbent made from natural materials (cellulose from red seaweed and sago starch) for treating textile industry waste. The hydrogel has demonstrated high absorption efficiency for various textile dyes, reaching up to 87.65% for purple dyes using the freeze-drying method, offering a sustainable solution for textile waste treatment.

Researchers have developed a new Metal-organic framework (MOF) material called ZIF-67 grown on cellulosic filter paper and cotton fabric for energy harvesting applications. The cotton fabric-based triboelectric nanogenerator (CF-TENG) demonstrated high durability over 14,000 seconds and generated maximum electrical output of 60V and 3µA with power density of 5 mW/m2. The technology enables biomechanical energy harvesting from human movements like finger tapping and running.

Researchers have developed a green synthesis method using molecular oxygen for producing iminonaphthofuranones, a category of disperse dyes. The process represents an environmentally friendly approach to creating color-adjustable dyes ranging from pale orange to dark purple, offering potential sustainable alternatives in the chemical and textile industries.

China's Economic Monitoring and Analysis Center has released price data for 50 key industrial and agricultural products across 9 categories, showing significant price movements in coal, steel, chemicals, and energy products. Coal prices declined across all types by 1.8-2.5%, while gasoline prices increased by 1.8%. The data covers major industrial inputs including metals, chemicals, petroleum, coal, and agricultural products, providing insights into China's industrial commodity markets and energy sector trends.

The paper reviews recent advances in bismuth-based catalysts for electrochemical CO2 reduction, focusing on synthesis methods, performance improvements, and industrial applications.

Researchers at University of Connecticut developed and tested an in-situ monitoring system for comparing electrochemical advanced oxidation processes to decolorize textile dyes in wastewater.

Researchers developed a novel polyvinyl alcohol-assisted MnO2-ZnO-CuO nanocomposite photocatalyst that achieved 93% degradation of methylene blue dye and 80% degradation of real textile wastewater pollutants.

The United States-Mexico-Canada Agreement (USMCA) has introduced groundbreaking compliance mechanisms for labor and environmental standards in international trade. The agreement includes a Facility-Specific Rapid-Response Labor Mechanism (RRM) and strengthened environmental provisions covering marine litter, sustainable forest management, and environmental impact assessments. Since its implementation in 2020, there have been 14 RRM cases and 10 environmental public submissions, demonstrating active enforcement of labor and environmental standards in North American trade relations.

The WTO members held meetings to discuss global cotton sector challenges, with a focus on sustainable development and climate impacts. The Cotton 4+ countries (Benin, Burkina Faso, Chad, Mali and Côte d'Ivoire) highlighted how climate change and high input prices are affecting cotton production. UNIDO has presented a roadmap to establish Africa as a sustainable textiles hub by 2035, while emphasizing recycling initiatives and sustainable practices in the cotton sector.
