The chemical industry development and mining, as well as the application of modern agrotechnical measures in agricultural production, have led to significant emissions of heavy metals into the environment, especially into soil and aquatic ecosystems. Such waters are not suitable for human consumption as well as for the needs of industry and irrigation, and it is necessary to find economically acceptable and efficient ways of their purification. Recently, there has been a growing interest in the use of low-cost, environmentally friendly and easy available materials for the removal of heavy metals from wastewater. Since the increase in population increases the production and processing of food, and thus the amount of organic solid waste, the aim of this study was to examine the possibility of using such waste in the treatment of water contaminated with heavy metals. To remove lead and zinc from aqueous solutions, waste collected from local plants for food production and processing was used as a biosorbent - olive pits, olive pomace pellets, and remains of the sea urchin, sour cherry pits and cherry pits. The experiments were performed in three consecutive sorption cycles by the batch process. The overall efficiency in removing lead after three cycles is from 37.6 to 89.2% and zinc from 58.43 to 75.09%, with the best removal on cherry pits. Observing the cycles individually, lead was best removed on cherry pits in all three cycles, while zinc was best removed on the remains of the sea urchin in the first cycle, on the cherry pits in the second cycle and on the sour cherry pits in the third cycle. Although the final concentration of both metals is not below the limit values, satisfactory removal has been achieved on all biosorbents. Reduction of lead and zinc concentrations to permissible levels for discharge into surface waters or into the public drainage system could be achieved by various modifications of biosorbents as well as by sorption by the column process, for which further research is necessary. Nevertheless, waste and residues from food production and processing can be used as biosorbents to remove heavy metals lead and zinc, which would reduce the total cost of water treatment and contribute to the concept of sustainable development.
