Un equipo internacional convirtió cáscaras de arroz desechadas en un filtro de biocarbón que capturó dos tintes industriales tóxicos en pruebas de laboratorio y mantuvo su eficacia durante al menos cinco ciclos de uso. La técnica podría reducir los residuos agrícolas y limpiar aguas; el siguiente paso será probarla a escala más grande.

Kenya, Ghana, Namibia, and Mali now require minerals to be processed domestically before export, ending the colonial pattern that extracted resources while leaving factories elsewhere. By controlling the value chain, these governments build industrial capacity and keep profits at home rather than shipping raw ore abroad.

From August 27, households across the UK will be able to install approved plug-in solar kits by connecting them to a standard wall socket.
