“Asphalt production is obviously a very energy-intensive process, so we were keen to find a new fuel solution that would not only deliver financial and carbon savings, but that would help boost the efficiency of our operations.
However, another major challenge was ensuring that we minimise production downtime, so any lengthy install that would require a long system shutdown was off the table. “Flogas’ LPG solution appealed to us because it ticked all the boxes. Initial projections showed that we could process the same volume of material but cut our yearly CO2e emissions by 25% per tonne of asphalt, reducing costs by almost 19%.
Figures that speak for themselves! “Replacing our existing system with a dual-fuel burner meant the switchover from oil to LPG was as seamless as possible, which dealt with any worries around disruption to production.
Flogas ensured the new burner worked with our existing oil infrastructure and scheduled the install to coincide with our usual shutdown period; only switching on the LPG once everything was in place. As well as the fuel savings from using LPG, putting in a more modern burner also made sense from a long-term perspective: we’ve made a 6% efficiency saving from the new system alone.”
