Sometimes, what goes up doesn't come back down — instead, it becomes a problem.
Junk is accumulating in space at a fantastic pace, millions of pieces orbit the Earth, from broken satellites to lost screws and tiny hunks of splintered paint. The International Space Station has to dodge it. Sometimes, space junk crashes into other space junk, creating more space junk. And while there have been many proposals for technologies to capture and destroy it, there's not been a system-level plan for dealing with it in a comprehensive way.
This week, researchers at England's University of Surrey published a paper outlining how to better deal with our celestial litter. The basic idea: make space more sustainable by using less material, repairing what's already up there, and recycling the junk we can't repair — and doing it systemically, industry-wide.

Material supply chains showed renewed complexity as Europe delayed enforcement of deforestation rules, affecting traceable sourcing of mass-timber and the embodied carbon in materials that underpin sustainable building practices. The deferral reinforces the need for lifecycle assessment and end-of-life reuse in construction, ensuring renewable building materials meet the standards of environmental product declarations (EPDs). Clients now prioritise deforestation-free, rights-respecting, low embodied carbon materials supported by circular economy in construction frameworks and robust whole life carbon assessments.
Rising energy prices across North America increase attention on energy-efficient buildings, deep retrofit strategies and life cycle cost optimisation. Developers are integrating eco-design for buildings that enhance operational performance while lowering the carbon footprint of construction. Water resilience is shaping sustainable building design in the UK, with drought prediction and reuse systems becoming part of life cycle thinking in construction and sustainable urban development.
The transition demands resource efficiency in construction and carbon neutral construction models that directly address the environmental impact of construction. Developers and contractors must commit to building lifecycle performance monitoring, circular construction strategies and sustainable material specification aligned with BREEAM v7 and similar frameworks. Environmental sustainability in construction now depends on design teams treating embodied carbon and whole life carbon as defining metrics for low-impact construction and durable, eco-friendly assets.
