Germany’s TopWerk Group and US-based Partanna have announced a partnership. TopWerk, a leading global equipment supplier for concrete products, regards Partanna’s carbon-negative binder as a direct, plug-and-play replacement solution to Portland cement, that is fully compatible with its machines (photo: finishing line by SR Schindler, part of TopWerk). Partanna has also confirmed its plans to use TopWerk machinery for its first factories. The exclusive agreement spans an initial term of three years with a global scope, including the recently announced plan for an upcoming carbon-negative concrete plant of Saudi Arabia’s property developer ROSHN.
