components. However, recycling of steel means the steel goes back to the mill to be melted down for production of new steel which generally requires more energy. Similarly, concrete frame buildings can be entirely reused saving on the production of new concrete, or the concrete can be crushed and down-cycled, but this usually only displaces some of the primary aggregate and not the concrete (which includes cement). Reuse will generally lead to considerably more significant greenhouse gas reductions, as can be seen in Table 8. This study summarised that the overall recycling and reuse initiatives saved 1,073,563 kg of carbon dioxide equivalent (CO 2 e), or 4.8 kg of CO 2 e per tonne of diverted CRD waste. The material contribution to net greenhouse gas savings was as follows: concrete (69%), vinyl windows (13%), steel (12%), asphalt (4%), with all the remaining materials amounting to 2%. The concrete was very significant due to three sites reporting concrete reuse which was attributed to the reuse of a building. Due to the greater benefit of reuse, this strategy accounted for 85% of the greenhouse gas savings across the seven sites assessed.
