<p><br /> Beijing is waging war against the stench of its growing rubbish tips.<br /> </p><p><br /> The city is sending over 100 deodorant cannons to blast the capital's surrounding landfills with stench-neutralising liquids as the rubbish begins to rot in the warmer weather.<br /> </p><p><br /> They were invented by employees at the Gao'antun Garbage Landfill Plant, in Beijing's suburbs.<br /> </p><p><br /> It followed apologies from local officials for the foul smells coming from the garbage dump, who promised to tackle the problem.<br /> </p><p><br /> Other devices such as odour eating sheets are also being used, along with a machine that extracts the foul-smelling gases and uses them to generate electricity.<br /> </p><p><br /> The cannons, officially termed "high pressure long-range deodorant sprays", blast a liquid created from plant extract onto waste arriving at the site.<br /> </p><p><br /> The biological compound neutralises the smell, its creators say, and the cannons can reach up to 15 metres away.<br /> </p><p><br /> The frangrance-covered rubbish is then buried under odour-eating covering sheets and further deodorant is sprayed on top.<br /> </p><p><br /> Beijing's 17.5 million residents daily produce 18,400 tonnes of household garbage, 90 per cent of which is dumped in the 13 landfills dispersed around the city.<br /> </p>
