Life cycle impact assessment (LCIA) is one of basic steps in life cycle assessment methodology (LCA). This paper presents the application of approach LCA for the rejections of drugs company SAIDAL, in order to determine the environmental impacts relative to this industrial activity, since it is classified among industry leader in the pharmaceutical field in Algeria, and that it takes part largely in the environmental disturbance by generating various categories of impacts. For this purpose, an eco-balance was establish by the collection of the theoretical data to the meadows of the company and of the practical data, resulting from the assay of pharmaceutical liquid.

In this paper, the adsorption of an anions dye Bezaktiv Yellow HE-4G onto mixture biosorbent, olive stones and date pits was investigated in aqueous solution. The effect of operational parameter such as initial dye concentration, time contact, temperature and pH was evaluated. The pseudo first-order and the pseudo second-order were used to describe the kinetics data. The data were evaluated for compliance with Freundlich and Langmuir models. Biosorptions data were successfully described by Freundlich isotherm model and the pseudo second-order model. Thermodynamic parameters indicated that the biosorption of BY HE-4G onto biosorbent mixture was spontaneous and endothermic in nature. The results indicated that the mixture of date pits and olive stone could be used as an adsorbent for textile waste water treatment without high cost.
