Özet

There are many scientific studies conducted by using duckweed to remove heavy metals from waste water. Duckweed plants have been used first time with this study for the removal of heavy metals from the paper-based packaging used as raw materials in recovered paper production. Objective of this study was to use an environmental friendly method to remove or decrease heavy metals from paper, paperboard and corrugated board. A mixture of Lemna minor, L. gibba and Spirodela polyrrhiza from duckweed taxa was used for the phytoremediation applications. The phytoremediation application was carried out on paper-based samples for 7 days in a batch reactor system to remove heavy metals such as lead, zinc, cadmium, nickel, copper, chrome and aluminum from the samples. Results showed that the duckweed plants can be used during the removal or decrease in heavy metal concentrations in the paper based packaging. It was determined that there was no removal or reduction heavy metals in the surface treated paper packages with low grammage.
