Some 4000 tonnes of spoil (concrete, bricks and soil) has been removed from the Senate House North Block and recycled for use on construction and landscaping projects within the London area.
The concrete and old bricks, which would fill two Olympic sized swimming pools, were excavated last year to form the space for the new glazed atrium at the centre of the building. The material was taken to a crushing and grading plant in the docklands. The recycled material has since been used in a range of new construction applications, furthering the positive impact of the re-development far beyond the School and its students and staff.
When carrying out the excavations, the soil was separated from the hard materials and was of a quality that it could be used directly for landscaping purposes. The majority was transported directly to a new golf and leisure complex being built at Northolt, in north west London.
Project Manager of Senate House North Block Keith Jennings said: “From the outset of the re-development of Senate House, a key consideration has been the impact on the environment. Typically, this type of building material would usually have limited use, however, the excavation and separation of materials on site has allowed it all to be re-used. Material from the current phase of demolition works is also being separated to ensure that re-use is maximised and waste minimised.
The combination of effective waste management, and sustainable technology such as the rainwater harvester all work towards the project’s aim of achieving an Excellent rating in BREEAM’s (Building Research Establishment Environmental Assessment Method), the industry standard for best practice in sustainable design.
