Move to recycle airport runways

MATERIALS

DISUSED airf ields across the country could be broken up as the Government steps up its bid to increase the amount of recycled aggregates used in construction projects.

Government-backed waste recycling body Wrap is to fund a host of research projects that aim to increase the amount of recycled and secondary aggregates used by the construction industry.

The schemes, launched under the Aggregates Research Programme, include projects to increase the use of foamed concrete incorporating recycled and secondary aggregates and develop new performance and durability tests.

They will also include a scheme to assess the potential for redundant airfields across England to act as a resource for recycled aggregates.

Contracts for the projects are due to be signed with researchers and contractors over the next two weeks.

Wrap's aggregates project manager Phil Wilson said: 'The projects will last for a minimum of 12 months, some almost double that.

'They will all go to meet the target of increasing the use and potential use of recycled and secondary aggregates throughout the UK.' Wrap has set a target for its Aggregates Programme to increase the production capacity for recycled and secondary aggregates by as much as 3 million tonnes per year by March 2006.

At the moment less than a quarter of the total yearly aggregate requirement in the UK of 275 million tonnes is met by recycled materials.
