Regenerative perfusion bioreactor for biologics production with lower COGs

Biotechnology Progress, EarlyView.
Abstract Perfusion bioreactor systems enable intensified bioprocessing with high cell densities and volumetric productivities in monoclonal antibody (mAb) manufacturing. However, their widespread adoption remains constrained by the high consumption of chemically defined cell culture media.

Hyperledger Fabric for the (digitalized) lifecycle of construction products: Applied review on fastening technology

Civil Engineering Design, Volume 7, Issue 1, Page 9-22, March 2025.
Abstract Blockchain technology is a digital decentralized data ledger recording transactions in an encrypted format. Its implementation can potentially hold significant advantages for the built environment, particularly in manufacturing and building product usage aligned with Building Information Modeling (BIM). This paradigm shift toward decentralized

Internal Carbon Cycles in the Steel Industry: Pathways for CO2 Management and Carbon Capture Utilization

Chemie Ingenieur Technik, EarlyView.
The steel industry accounts for about 7%‐9% of global CO2 emissions. While H2‐based direct reduction is a long‐term route, near‐term solutions are needed for existing plants. Internal carbon cycles reuse steelworks off‐gases and by‐products, enabling circular carbon use and supporting CCU integration.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry

Chemie Ingenieur Technik, EarlyView.
The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.
