This is exactly what construction company Alfred McAlpine did when building the new A30 Bodmin to Indian Queens Bypass improvement scheme.
While providing the road with a new seven mile dual carriageway stretch, the Bodmin landfill site sat in the middle of the planned route.
Alfred McAlpine Project Services principal quality, environment safety and health advisor David Gibson said: We put the road right through the middle of the landfill. To do this, we excavated approximately 17,000 cubic metres.
But the process wasnt just digging and dumping, we got a sub contractor to sort out the waste. After excavating, we handpicked all the rubbish out and found lots of steel and some very handy materials.
We treated the leachate and sewage and actually recycled 85% of all the waste. We produced aggregate for landscaping areas and only 2,500 cubic metres went back to landfill.
The company also used a large amount of aerosol paint on site. By piercing the containers, letting the butane escape through filters and then letting the paint dry, these were no longer classed as hazardous, meaning they could be recycled.
Steel tubes and bird cages can then be made from these, a process that is being utilised throughout the company.
Gibson added: If anyone travelled to Bodmin during the summer, Id like to apologise for the disruption. But the project is nearing completion and will be lovely in the next month or so.
