Aggregates and sand - from recycled resources - no heat treatment - bulk - loose

Emission intensity of aggregates and sand - from recycled resources - no heat treatment - bulk - loose. Based upon the stastical average of all data collected for recycled aggregates with no heat treatment in the ICE Database. Recycled aggregates include aggreagates from construction and demolition waste. It does not cover secondary aggregates such as blaast furnace slag or bottom ash (see seperate category for these). Data for recycled aggregates is more difficult to obtain than for virgin aggregates. There is also a large range in results for recycled aggregates adding uncertainty into the results. 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.
