Waste
England and Wales produce 375million tonnes of waste every year, of which the Construction and Demolition Industry generates approximately 89million tonnes of this waste.
Most of the waste generated in the UK is placed in landfill sites, which is not a sustainable option;
The effective management of waste generated by our construction and facilities management activities is fundamental to our sustainability strategy and as such we have reassessed our mechanism for gathering waste management information. In doing this we hope to more clearly understand the costs of waste management which we can then use as a business driver both for our project managers and clients, to ensure that we minimise wastes generated.
We have appointed a Supply Chain Category Manager with responsibility for waste to concentrate on further reviewing how we gather waste management information across the Group. This will help to improve our understanding of the costs of waste management and identify ways of further minimising waste.
To help our projects in the implementation of effective waste management we have developed waste management guidance, which is available to all projects. In addition we have set more challenging targets for 2003 for reducing waste in our offices and our projects.
Examples of Project Waste Management
At the M6 Toll Project we are seeking to reuse site won materials as opposed to sending it to landfill. For example,
- 250,000 tonnes of U1/U2 material have been separated on site for reuse
- 700,000 tonnes of Cement Bound Materials
- 2.3 million tonnes of sand and gravel have been reused
- 5,000m3 of vegetation clearance material has been mulched and added to topsoil
- Around 10% of waste (wood, paper, plastic and metal) has been recovered for recycling
Our Carillion Building project at Dell, Bracknell has implemented the following waste minimisation activities;
- Specialist waste manager (ICWM) employed to service skips and rubbish clearance
- Wheeled bins provided at workface to cut down on rubbish in building and better facilitate segregation ‘at source’
- A waste segregation area was created on tarmac hardstanding and the 20 yard skips appropriately labelled
- Waste segregation is in operation
Carillion Services is helping the Queen Elizabeth and Queen Mother hospital to manage its waste more effectively. The new Renal Unit of the hospital introduced a standard charge for each bin of clinical waste as opposed to a flat rate. This resulted in staff being more aware of the types of wastes placed in the clinical waste bin and has led to a 50% reduction in the number of clinical waste bins being disposed of, resulting in a cost saving for the Trust.
Our Nicholas Tower project in Trinidad developed posters to help communicate the examples of reuse of waste construction materials. For example, a poster was used to communicate an alternative use of excess concrete.
