Research the different environmentally friendly construction material. Investigate the environmental techniques used prior, during and after the construction. Investigate other organisations who use environmentally friendly materials. Objectives
Waste soil, topsoil and other aggregates 300,000 tonnes of waste concrete and demolition material from T5 crushed by a designated team and reused on site. Biopiles used to treat the contaminated soils. Excavated inert soils and clays used as backfill and for landscaping. Multiple use of temporary works Reusing waste material
Waste arising from road sweeping activities • A materials take back scheme • Lengths of cable too short to be of use to the permanent systems installation team were made available to the logistics team for use in the temporary systems on site. • Surplus paint of good quality was made available to local community projects through the Community Re:Paint initiative.
Skips were provided Waste cable and plasterboard were also segregated for recycling Overall 87% of waste was recycled. Recycling Material
Temporary site drainage Biodegradable waste Specific Recycling initiatives
BAA worked hard to include material with high recycled content in the construction of T5. • 80,000 tonnes of recycled and secondary aggregates were bought in. • Crushed glass from local recycling banks- site roads • Up to 30% of the concrete mix used in the construction of buildings, taxiways and aircraft stands is pulverised fuel ash. Recycled
9,100 tonnes of co2 emissions. Cost savings Higher quality product Benefits
