An Environmental Product Declaration (EPD) for the upcycling of bricks!

EPD

StoneCycling is a company with the mission to ‘upcycle’ as much waste as possible and convert it into unique and beautiful building materials. One of their products is the WasteBasedBricks, made from bricks from different waste streams. 

We have carried out an Environmental Product Declaration (EPD) for Stonecycling. An EPD communicates the information from a previously made Life Cycle Analysis (LCA). With an EPD, buyers can easily map out the environmental impact of different products.

In the LCA, the WasteBasedBricks are compared with the production of standard bricks. In addition to general information and production description such as the different products and their dimensions, attention is also paid to the calculation of the LCA.

The system boundaries are described because there are several ways to calculate an LCA. A cradle-to-gate approach is used in this LCA. This means that all processes from the extraction/production of the raw materials and energy (carriers) up to and including the production of the bricks are included in the calculation.

Tables are shown of  the life cycle inventory of the products. Including all energy use and an overview of all the emissions as a result of the production processes.

To explain the benefits of replacing conventional raw materials with ‘waste flows’, a system expansion scenario is applied. This means that processes are excluded from the production system because they are avoided through the use of the waste streams. These processes include final waste processing, mining and the transportation of raw materials. 

The above results in an overview of the results of the Life Cycle Analysis in a table and graph. From this data, StoneCycling customers can clearly see how the two types of WasteBasedBricks compare to normal bricks in different environmental categories. The WasteBasedBricks save on new material, add new value to waste materials and have lower energy consumption during production because the bricks are fired at a lower temperature.
