District heating creates circular economy at our factories
Since 2016, we have implemented 40 energy-saving projects across our business which have saved 6600 tons of CO2 –– a huge 32% reduction on our overall energy consumption (gas and electricity). A key project that helped us achieve this saving was our district heating initiative.
As Envases’ factory production lines emit a significant amount of waste heat, we realised we had the opportunity to recover and reuse it. Since 2014, we have consistently fed our excess heat to the public district heating supply, helping deliver cleaner, more sustainable energy to the grid. While this initiative was a step in the right direct, we knew we could make a bigger impact by reducing our overall reliance on natural gases to heat our factories.
In 2020, we cut our consumption of natural gas by internally recirculating our waste heat to warm our factories, as well as taking recovered heat from the district heating plant to supplement our own. In doing this, we were able to completely shut off our factories’ gas-fired boilers and make an annual saving of 3,122 tons of CO2.
This initiative has enabled us to create a more circular heating economy inside our factories and improved our ability to make more sustainable choices.
