REVIEW ON ADVANCED TECHNOLOGIES FOR ALUMINUM RECOVERY FROM CARTON PACKAGES WASTE USING PYROLYSIS
REVISÃO SOBRE TECNOLOGIAS AVANÇADAS PARA A RECUPERAÇÃO DE ALUMÍNIO DE RESÍDUOS DE EMBALAGENS CARTONADAS USANDO PIRÓLISE
Palavras-chave:Pyrolysis, Carton Packages, Aluminum Recovery, Spouted Beds
Pyrolysis is green technology allowing for the separation of polyethylene and aluminum composite from Tetra Pak. This alternative can be used to reduce the environmental impact arising from the unsuitable disposal of this modern waste. In addition, recycling enables the recovery high added value materials. For the recovery of aluminum and paraffinic oils from carton packaging waste, this review paper aims to highlight the advances in science and technology for aluminum recovery from carton packages. Among the reactors analyzed, spouted and fluidized beds can be pointed out as new opportunities and industry-leading successes over the upcoming years. Concerning economic potential, two factors show the pyrolysis of carton waste as a promising technique: the added value of recycled materials and process energy saving. Based on economic analysis, pyrolysis has a positive economic potential of 190.5 US$/per ton of product. When compared with the traditional process to produce aluminum, pyrolysis can save 0.745 MWh per ton of recovered carton package. Concerning the process profitability, plasma pyrolysis has a 3.27 Million cumulative cash ratio and a 2.04% rate of return on investment, showing itself as an attractive investment.
