The Use of a UV Lamp for Control of Odour Decomposition of Kitchen and Vegetable Waste

Laboratory-scale tests have been conducted to reduce odour from domestic garbage waste kept for two weeks in a container. A 5W UV lamp OSRAM HNS 5/U0ZE27 inducing ozone formation was used at a rate of 7 hours per day. Using the Electronic nose FOX 3000 technique, the odour expressed as Sensorial Odour Perception (SOP) units, was 19470 SOPav.l−1gas, while in the non-treated control it was 132 000 SOPav.l−1gas. The results showed that off gases from domestic waste became less charged after having been subjected to an UV lamp producing O3. This technique offers potential for the storage of waste, avoiding odour and flies breeding during summer time in the temperate climates and during all seasons in warm countries.
