Use of cullet to reduce raw material and energy consumption
Guardian Glass EU plants increased average cullet ratio (broken glass) in their glass from 22% to 26% between 2019 and 2021.
PVB recycling
Our 6 European plants send excess PVB trims back to our suppliers for re-introduction into their manufacturing process, reducing waste and saving resources.
Local sourcing of raw materials
Where feasible, we strive to source the raw materials for our float batch at a regional level. (Mainly sand, soda ash, dolomite, limestone, salt cake and cullet).
For all of our European plants in 2022*, the majority of the batch raw materials used to manufacture our ExtraClear and UltraClear float production comes from suppliers within an 800 km radius.
(This is the distance considered to be regional in the LEED v3 rating. Our teams can provide specific Regional Material & Recycled content statements for you to earn LEED points on your projects). Some of our plants are even 100% locally sourced.
*Regional material content can vary over time
