10. Concrete Blocks Are greener than you may think Cements Content only 9% * 1 19% of above are ‘alternative’cement’s Aggregates are often ‘surplus’ dust from quarries Blocks can be 100% recycled aggregate * 1 WRAP Resource Efficiency Action Plan

11. Concrete Blocks Embodied Energy 6Kg CO 2 /t blocks * 2  That is 7 times less than softwood  That is 30 times less than steel  That is 40 times less than plastic * 2 Uni. Bath Inventory of Embodied Energy 2008 (Excludes Calorific Value of wood) Are greener than you may think

12. Concrete Blocks Manufacturing waste is re-used (WRAP) Energy used in manufacture only 21kW.hrs/t Less than 2% wastage on site Delivery average 60 miles from 100 plants across the UK Are greener than you may think CO 2 Footprint does not need to measured from the Port of entry
