The generation of leachates containing heavy metals, salts, and organic contaminants like polycyclic aromatic hydrocarbons (PAHs) makes municipal solid waste landfills a major contributor to soil and water degradation. Because traditional remediation techniques are often cost-prohibitive, sustainable approaches such as phytoremediation have gained considerable attention. This research investigates the efficacy of Paulownia tomentosa (Oxytree) in restoring soils impacted by landfill leachates. In a controlled green...

Waste and the landfills have been accompanying man for centuries. Although modern technologies limit the impact of landfills on the environment, the landfills where waste materials used to be buried still have an impact on the environment. The studies into the waste itself are performed on small samples, mainly with static leaching tests. These are quick and relatively cheap methods. However, conducting leaching tests on small samples may result in failing to detect some leached substances. Lysimeter studies, due ...
