UK Tube Company Leaves Nothing to Waste

UK Tube maintenance and infrastructure company Tube Lines is undertaking a new initiative to reduce its carbon footprint and play a part in London's aim to become the greenest city in the world.

Working with the National Industrial Symbiosis Programme (NISP) - the world's first nationwide symbiosis programme to help companies maximise their resources - Tube Lines has been working on landfill sites to remove and reuse waste materials.

As part of the Zero Waste to Landfill scheme, Tube Lines has removed 4,150t of waste material from a site on the Embankment in London where reprocessed topsoil has been used together with logs to preserve a natural wildlife habitat.

Over 1,900t of soil and clay has been reused as capping material at a landfill site in Gerrard's Cross, just outside London, while 100t of concrete and rubble was crushed for re-use as aggregate.

Tube Lines is responsible for maintaining and upgrading infrastructure on the Jubilee, Northern and Piccadilly lines on the London underground, which makes up 40% of the underground network.
