An apparently simple environmental strategy deployed on the £65M Heathrow Terminal 3 redevelopment saved an impressive amount on project costs. Instead of taking building waste to a landfill tip, it was collected and recycled, saving up to £41/t and £11,000 overall.
This phase of the Terminal 3 project involved moving security inspection facilities and other services to a newly built area.
Meanwhile, the vacated area was refitted with retail, lounge and toilet facilities. The total project covered an area of 8,200m 2. 'Instead of leaving each contractor to sort out his own waste, we employed logistics contractor Wilson James to do it for them, ' says Chris Ctori of the BAA team. Waste management specialist SITA was contracted to sort and salvage the waste.
'Wheely' bins of 360l/1,100l capacity were dotted around the site and filled constantly by Wilson James's collection team.
There was no need for skips outside the terminal building, freeing operational space and removing the danger of windblown debris damaging aircraft.
Apart from the environmental benefit of keeping reusable materials that would otherwise have gone to landfill, there was also a financial gain. The combined cost of transport and landfill tax means disposing of wood and metal costs £41/t and inert material £31/t.
Overall, £11,000 was saved simply by reducing the volume of waste discarded. Further cost gains were made by selling recovered materials.
Lessons learned on the Terminal 3 redevelopment have been so striking that waste recovery is to be implemented on all future BAA projects.
