Experimental drone used to monitor rubbish dump gases

An experimental drone fitted with sensors is being deployed to monitor gases rising from rubbish dumps.

The unmanned aircraft is being flown above Britain's 200 landfill sites to study a major source of UK emissions.

The latest estimate is that unwanted food produces 21 million tonnes of greenhouse gas in the UK every year.
