Professor David C Wilson will present a paper at the Great Waste Seminar on 19 October, the last in a series of events to celebrate the centenary of the Chartered Institution of Wastes Management (CIWM)’s London and Southern Counties Centre. His focus is on the ‘forgotten chapter’ in the history of organised waste management, the dust-yard system in London that achieved 100% recycling (‘zero-waste’) for much of the period from 1790-1850.  UPDATE: this paper has now been written up and published in the journal Waste Management.
