Direct recovery of Zn from wasted alkaline batteries through selective anode's separation

Autor: Inês V. Valdrez, Manuel F. Almeida, Joana M. Dias

Publikováno v: Journal of Environmental Management. 321:115979

In the present study, a leaner process for recovering zinc from spent alkaline batteries is studied at a laboratory scale. Such process is part of a diagram, under development, that aims at maximizing the value of all the battery components while red

Advanced and clean technologies for chromium tanned leather waste recycling and green energy production

Autor: Maria José Ferrreira, Vera V. Pinto, José Rodrigues, Sílvia Pinho, Maria Azevedo, Manuel F. Almeida

Chromium tanned leather wastes are difficult to valorise by chemical and biological processes dueto the strong bonds established between collagen and chromium. Thus a one-step fast clean pressureassisted alkaline hydrolysis method has been studied to
