Simply by modifying its Beringer oven system…

What is a Beringer oven?
In order to avoid the infiltration of non-desirable matter in the geomembrane during the fabrication process, filters are installed at the exit of the extruder. The Beringer oven is a system that is responsible for cleaning and removing the resin residues that build up in the filters.

How does it work?
The filters are placed in the Beringer oven and heated at a high temperature to burn off the plastic residue. After that, a steam and aspiration process allows for the recuperation of paraffin emitted during the combustion. This process uses a lot of water: 265 gallons (1,000L) per utilization (3 times/week). For Solmax, this represents approximately 50% of our overall consumption, which is considerable.

What has changed?
Our engineering department came up with the idea of modifying the process, making it possible to reuse the water used to clean the filters and recuperate the paraffin deposits. They integrated the equivalent of a closed loop, which instead of sending the used water into the City’s wastewater system every time, stores it in a reservoir where the water is filtered and subsequently reused.

Benefits for Solmax and the environment:
- Considerable reduction expected of our water consumption (statistics to be announced shortly)
- Discharge of cleaner water into the sewer system (previous discharges were nonetheless acceptable)
