Abstract: We have performed a laboratory study using concentrated solar radiation to destroy hazardous organic wastes. The intensity of simulated solar radiation and the exposure temperature were varied for a series of test materials using a specially designed system designated the Thermal/Photolytic Reactor System (TPRS). The high-temperature destruction efficiencies (DE) for the test compounds, exposed to 57 suns of radiant flux, were consistently greater than the DE observed under non-irradiative conditions. Calculations, using simple thermal/photolytic models, indicate that DEs may be increased by factors of 104–106 over purely thermal destruction for solar flux levels of 500–1000 suns. Furthermore, observed red-shifts in the high-temperature absorption spectra of the test compounds suggest that a wide variety of compounds may be amenable to this process.
