With a total of 2 patents, his work addresses critical issues related to waste management and environmental protection.

Latest Patents

Hochleitner's latest patents focus on the fixation of heavy metals, mercury recovery, and dioxins destruction in fly ash. One of his notable inventions presents a process for stabilizing lead in fly ash, which involves calcining a mixture of fly ash and specific calcium-containing compounds in the presence of an oxygen-containing gas stream. This process is conducted at temperatures ranging from about 475°C to less than 600°C for durations between 30 minutes and 5 hours. The treated MSW fly ash results in leachates containing lead concentrations that are below the EPA regulatory limit. Another patent outlines a similar process for stabilizing heavy metals, which involves calcining fly ash at temperatures between 400°C and 600°C for times ranging from 170 seconds to 5 hours. This method also ensures that the leachates meet EPA standards for heavy metal concentrations.
