Paper Title
Innovative Waste Treatment Cycle for Aluminium Industry

Abstract
Nowadays challenges in industries abroad are environmental oriented. As landfilling is getting more restricted, new, innovative options are addressed. Also, the aluminium industry is not immune to this problem as it generates tons of hazardous wastes. One of them is especially critical as no proposed treatment technology is economically justified. Spent Pot lining (SPL) is a hazardous waste material which originates from the primary aluminium production – the electrolysis cathode pot. Suggestions from the professional and scientific sources on how to approach the problem with state-of-the-art solutions were taken into account. A robust model to economically treat SPL is presented. Keywords - Alkaline – Acidic treatment, flotation, spent pot line, waste treatment.
