Inside a highly classified facility in Oak Ridge, Tennessee, workers are turning old, unexploded warheads into fuel that will power cities.
The recipe to create advanced reactor fuel involves melting weapons-grade uranium with low-enriched uranium in a crucible — a massive, metal cauldron heated to around 2,500 degrees Fahrenheit to turn its contents into molten soup.
Emerging from its furnace, a glowing orange cast filled with the hot liquid uranium is slowly lowered into a cooling chamber. The hardened finished product, which looks like black charcoal, can be safely held in-hand.
This fuel is set to power the next generation of America’s nuclear reactors — small, modular power stations that are easier and cheaper to build. They require far less upkeep and physical space than the aging fleet of large nuclear power plants.

Europe’s acceleration of low carbon steel investment marks a decisive step toward decarbonising the built environment and controlling embodied carbon in new infrastructure. Germany’s strong state aid signals that low embodied carbon materials will soon define procurement preferences and affect both whole life carbon assessment and life cycle cost analysis in major developments. Materials with verified certifications for net zero whole life carbon will gain priority as sustainable construction frameworks evolve, reflecting client demand for transparent supply chains and lower carbon footprint of construction.
At project scale, the expanding circular economy in construction is reinforcing resource efficiency in construction. London’s new glass recycling facility will feed green building materials into façade and insulation supply chains, strengthening sustainable material specification for eco-design for buildings. Biochar’s role in carbon footprint reduction remains promising, though dependent on circular construction strategies and mature quality assurance to guarantee durable results. Genuine environmental sustainability in construction relies on traceable, scalable systems that clarify the environmental impact of construction.
Programmes targeting industrial efficiency continue to deliver the cheapest form of decarbonisation. Proven operational measures are expected to cut emissions by millions of tonnes and reduce costs, encouraging the sector to address whole life carbon at every stage of the building lifecycle performance. Investors and clients now see sustainable building practices and low carbon construction materials not as innovation but as standard risk management. Strengthened oversight of waste streams underlines that circular economy ambitions require clean closure at the system’s end, ensuring claims of sustainable building design and green construction remain credible.
