The current legislation on the disposal of road sweeping sludges is anomalous because certain road sweeping sludges are exempt from the requirements of the Special Waste Regulations 1996 – not because of their chemical composition but rather as a result of the legal definitions applied by the Controlled Waste Regulations 1992. This has led to sweepings from trunk roads (under the control of the Secretary of State) being classified as ‘special’waste, but sweepings from roads vested in the local authorities classified as ‘household’waste. Although the chemical composition and potential health hazards associated with road dust have been studied, data on the chemical composition of road sweeping sludges are sparse. This study analyses twenty‐four samples of road sweepings in order to chemically characterise the sludge.
