Partner Highlight - Cleveland's Glowing Silos: Heidelberg Materials' Hub for Sustainable Cement Supply
The twin, glowing silos on Dock 20 at the mouth of the Cuyahoga River are among the most visible structures on the Cleveland waterfront. They hold cement powder and are home base to the Port of Cleveland’s longest-tenured tenant – Heidelberg Materials – which provides the raw materials needed to make concrete for projects across Northeast Ohio.
Heidelberg Materials is one of the world’s largest manufacturers of building materials. They have leased the silos since 1997 and will continue to operate there through 2047.
The silos hold 12,900 metric tons of finely milled cement powder, the primary raw material in the production of cement. The cement arrives via vessel from a cement plant in Picton, Ontario, and is blown into the silos upon arrival.
Heidelberg Materials also operates other inland facilities in Ohio and across the nation, but they emphasize the benefits of their waterfront location for local companies.
“Shipping via vessel is a more cost effective mode of transportation and it is significantly more sustainable,” said Bill Corcoran, VP of Logistics for Heidelberg Materials North America. “A ship can carry 100 tons of materials, while a truck can carry 10 tons and a rail car can handle 10,000. We can operate more efficiently via the port, and that benefits our customers as well.”
The raw materials are used by ready-mix concrete companies, precast concrete producers and general contractors for projects across Northeast Ohio.
An average of 40-50 trucks pick up about 10 tons of cement each day at the Port’s Dock 20, though it could vary per season.
The silos are operated by two Heidelberg Materials employees but support dozens, if not hundreds, of indirect jobs including truck drivers, maintenance workers, laborers, and other contractors.
In 2016, the 150-foot tall silos were artistically lit by the Port of Cleveland to create a public art display known as “Harbor Lights” ahead of the Republican National Convention. “These are industrial facilities, but we are also passionate about creating an inviting waterfront for residents and visitors,” said Port CEO William Friedman.

Port’s Green Marine certification renewed
Port’s Green Marine certification renewed
The Port’s Green Marine certification was recently renewed. Green Marine is a voluntary environmental certification program for the North American marine industry. It targets prioritized environmental issues such as greenhouse gases, community impacts and water and land pollution. To get re-certified, the Port had to benchmark annual environmental performance through exhaustive self-evaluation guides, have results verified and agree to publication of those results.
The Port of Cleveland was a founding member of the Green Marine program in 2007. In the recertification, the Port achieved “continual improvement” by improving levels in both the Air Emissions – Greenhouse Gases and Community Relations performance indicators.
