This paper is focussed on a techno-economical analysis comparing TiO2-Persulfate and Photo-Fenton methods for Solar Detoxification of pesticides from an industrial point of view and considering the photocatalytic system coupled with a pesticide bottles recycling plant. The analysis is based on the experiments performed at PSA Solar Detox facility with 250 L of a mixture of 10 commercial pesticides, which have been treated with both photocatalytic methods in the same CPC-type reactor system. The initial TOC of the pollutants was 100 mg/L (considering not only the active ingredient but also the rest of the commercial formulation components) and the final TOC 10 mg/L (plant design parameters). Different experiments have been performed to optimize both treatments. In the experiments with Photo-Fenton 80% of the initial TOC were removed in 75 to 90 minutes and 90% in approximately 2 hours. In the experiment with TiO2-Persulfate, 80% of the TOC was removed in 3 hours and 90% of the TOC after 4 hours.
