Hazelwood Green, the transformative redevelopment of Pittsburgh's historic 178-acre LTV Steel site on the Monongahela River, has announced three major tenant commitments totaling 120,000 square feet of laboratory and office space. The new tenants include a biotech company, a climate technology startup, and a manufacturing training center. These commitments advance the site's evolution from industrial manufacturing to a mixed-use innovation campus serving emerging sectors critical to Pittsburgh's economic future.
Hazelwood Green is developed through ALMONO LP, a partnership of major Pittsburgh philanthropic foundations committed to transforming the former steel mill into a 21st-century innovation district. The site's riverfront location, remediated infrastructure, and commitment to sustainable development create a distinctive platform for companies seeking collaborative environments and access to Pittsburgh's research institutions and skilled labor.
"Hazelwood Green demonstrates how Pittsburgh transforms industrial legacy into innovation opportunity. The site is becoming proof that industrial cities can lead in emerging sectors."

The site already hosts Mill 19, a landmark adaptive reuse project that converted a historic steel mill building into flexible laboratory and office space. Mill 19 now houses Carnegie Mellon University's Manufacturing Futures Initiative, establishing the site as a center for manufacturing innovation research and practice. The new tenant commitments build on this foundation, diversifying the campus's sectors and tenant base.
The biotech company tenant will occupy specialized laboratory space designed for life sciences research and development. Pittsburgh's biotechnology sector has grown substantially in recent years, supported by UPMC's medical research activities, academic partnerships, and venture capital interest. A dedicated biotech tenant at Hazelwood Green reflects growing demand for specialized facility space that can accommodate sensitive laboratory requirements and collaborative research environments.
The climate technology startup tenant reflects Pittsburgh's emerging strength in clean technology and sustainable innovation. The site's commitment to environmental remediation and sustainable development creates a natural affinity with climate-focused companies. The startup's presence at Hazelwood Green signals that Pittsburgh is attracting venture-backed climate companies, positioning the city within emerging economic sectors beyond traditional energy and manufacturing.
The manufacturing training center tenant represents a strategic investment in workforce development. As manufacturing evolves toward advanced, technology-intensive production, the need for workers with specialized skills in automation, robotics, and digital systems grows substantially. A training center at Hazelwood Green can serve regional manufacturing companies while preparing workers for career advancement in modernized production environments.
The total investment in Hazelwood Green now exceeds $400 million, representing one of Pittsburgh's largest private development projects. The site's transformation from industrial production to innovation-focused mixed use reflects broader economic transitions reshaping Pittsburgh. The ability to preserve industrial legacy while creating modern innovation infrastructure positions Hazelwood Green as a model for post-industrial urban development that honors history while embracing future economic opportunity.
