2.3. EPD Example

An EPD was developed for a New Zealand ready-mix concrete company in order to determine the environmental impact associated with the production of one cubic metre (m³) of normal grade ready mix concrete.  The inventory information for one grade of concrete is displayed below.

Table 2: Batching plant material summary for 50MPa concrete

1Electricity values represent electricity used to manufacture all products, all compressive strength classes - not just 50MPa

2Wastewater values are for site - not just 50MPa

The figure below shows how EPD's can be used to compare the environmental impacts of similar products.
