Aggregates and sand - mixture of recycled and secondary resources - bulk - loose
Emission factor summary
Emission intensity of aggregates and sand - mixture of recycled and secondary resources - bulk - loose. Data on recycled and (particularly) secondary aggregates would benefit from improvement. Limited data on the embodied carbon of secondary aggregates was available. There was also limited data on the consumption mixture of recycled and secondary aggregates in the UK. The mixture was modelled with 33% secondary and 67% recycled aggregates. [Estimated from Ref: Aggregates cement and ready-mix concrete market investigation Working paper on market definition for aggregates cement and RMX. ND67. Available from: https://assets.publishing.service.gov.uk/media/5329dfb440f0b60a730002cf/market_definition_housestyled.pdf] The source does not clarify if the kgCO2e value is calculated using either IPCC Fourth Assessment Report (AR4) or IPCC Fifth Assessment Report (AR5) methodologies.
