Specifically, siloed processes and a lack of integrated tools at the disposal of Synonym meant that project speed and flexibility were hindered. It’s for this reason that in 2026, Roebling expanded its predecessor's biomanufacturing remit into the wider industrial landscape and now acts as a platform for industrial process engineers. Its tools include techno-economic analysis, process design and cost estimation, helping industrial project stakeholders to accelerate project timelines through data analysis. Reportedly, a first-of-its-kind platform, Roebling is deftly utilizing its years of prior experience to help biomanufacturing, food and agriculture, critical minerals, chemicals and energy projects to speed up their processes. With a back catalogue of Fortune 500 companies served under Synonym, it will be interesting to see how Roebling expands its customer base and utilises its preexisting partnerships.
