What should a local Authority do with its rubbish? In this lively programme, Andrew Porteous of the Open University presents the options and George Cooper, Chief Cleansing Officer with Bradford Cit...y Corporation,gives the reasons for Bradford's choice. The programme compares Bradford's incineration process at Hammerton Street within the city, with their controlled tipping operation at Odsal just outside the city. Bradford's limited recycling process is also examined and the pros and cons discussed.
