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(-1)gas, while in the non-treated control it was 132 000 SOPav.l(-1)gas. The results showed that off gases from domestic waste became less charged after having been subjected to an UV lamp producing O-3. 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.
