Aluminum and fumed silica as solid industrial wastes were converted to zeolite NaPas a value-addedproduct without any template. The hydrothermal process was optimized using static autoclave. The crystallization was carried out at 100, 120 and 150°C for 24, 48 and 72 h. The prepared zeolite of Si:Al ratio of 1.2 was characterized using X-ray Diffraction (XRD), Scanning Electron Microscope (SEM) provided with Energy Dispersive Spectroscopy (EDS), Surface Area, Fourier Transmitted Infra-Red (FTIR) and Thermal Analysis (TG-DSC). The crystalline phase was formed at 100°Cafter 72 hours and at 120°C after 48 hours, while it was formed after 24 honlyat 150°C. Increasing temperature and time lead to the conversion of the prismatic gibbsite crystals into plate-like structure of zeolitewhich is then formedcauliflower-like structure.The prepared zeolite was employed as adsorbent for Ni2+and Cu2+ions from aqueous solution.The kinetic studies of adsorption processes were performed.

In the article legal aspects of the recycling of the laquered aluminium drink packaging wastes were presented. The recycling of the wastes of this kind is very important for the polish economy, because it allows to win back a very valuable raw material, namely the aluminium. In the opinion of the experts there will be observed an increase of the consumption and of recycling grade of the aluminium drink packaging boxes in Middle and Eastern Europe. The legal regulations shall become the driving force for the development of the polish recycling industry of the secondary raw materials.
