Partanna Global CEO Rick Fox said “TopWerk's endorsement of Partanna represents a major vote of confidence in our technology from one of the most respected names in global construction. We’re humbled and proud that one of the world’s leading concrete machinery producers has given us their backing. We hope this signals to the industry that Portland cement is no longer the only solution in town, and that the days of burning rocks are fast coming to an end.”
TopWerk CEO Robert Gruss said "We believe our exclusive partner Partanna has come up with a truly impressive solution that can contribute to putting this polluting practice to an end. The company’s carbon negative binder is one of the most exciting innovations we have witnessed in our industry for decades. It is the most advanced alternative binder solution in the market and the only credibly carbon negative solution that has the potential to scale globally. Over the last two years, we have rigorously tested their formula and have validated its application as a direct replacement solution for Portland cement. In many ways, their binder actually performs better than the legacy solution.”
The endorsement follows Saudi Arabia-based property developer ROSHN's announcement of an upcoming carbon-negative concrete plant that will use Partanna Global's technology earlier in January 2024.
