Cutting carbon in construction
John Barritt
Construction Materials Sector Specialist
WRAP ‘Designing out Waste’ tools and guidance for maximising the carbon benefits of resource efficient construction
Reducing waste and carbon through an efficient site waste management plan
Exploring the options for recycling concrete without increasing net carbon
Defining model procurement requirementsfor carbon efficiency in construction projectsand facilities management
WRAP Tools
Identify opportunities to design out waste in buildings projects;
Record design solutions pursued to reduce material consumption, wastage and carbon;
Calculate the impact of these solutions, including savings in project costs, waste to landfill and embodied carbon;
Compare the performance of different projects / alternative designs; and
Provide an indicative waste forecast for your Site Waste Management Plan(SWMP).

and use
Crushed concrete produces a quality recycled aggregate
What are the most resource efficient and low carbon uses for aggregates produced from concrete?
Recycled aggregates as coarseaggregate for concrete:
Limitations within concrete standard restrict use
Viable technical options for non structural concrete
>20% in structural concrete increases water demand, cement content and carbon
Use should be close to crushing operation to prevent high transport carbon
2008 aggregate market
sand & gravel
28%
crushed rock

recycled/secondary
28%
