2022 was another productive year in laboratories across the United States and beyond, as colleges, manufacturers, and startups strove to challenge the orthodoxy of construction materials. While teams of students and researchers at institutions from Virginia Tech to ETH Zurich sought to push the... View full entry
Zaha Hadid Architects has published details of its proposed master plan for the Odesa Expo 2030 bid. In seeking to secure the Expo 2030 contract for the southern Ukrainian city, the design team has presented a scheme composed of “demountable” and “redeployable” pavilions after the event...

A group of research students at ETH Zurich has completed a timber geodesic dome constructed from nothing but demolition waste. The research group, led by assistant professor Catherine De Wolf of the university’s Department of Civil, Environmental and Geomatic Engineering, sees the project as a... View full entry
Back in June, we covered news of research set to be undertaken at Penn State on the subject of embodied carbon in cities. The research, one of many stories this year focusing on embodied carbon, signals a growing awareness in academic and professional circles of the need to include whole-life... View full entry
Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste. [...]
Joint lead author, Dr Rajeev Roychand, said there was real potential for construction industries around the world to play a significant role in transforming this waste into a valuable resource.

According to the RMIT researchers, an incredible 54,000 tons of PPE waste has been produced daily since the start of the pandemic. "With a circular economy approach, we could keep that waste out of landfill while squeezing the full value out of these materials to create better products &mdash... View full entry
When old office blocks are demolished, their steel frames are typically smelted down to be recycled, emitting thousands of tonnes of carbon in the process. But at One Broadgate, the steel beams that once framed the London headquarters of inter-dealer broker TP Icap Plc will instead be salvaged from the site and recycled by developer Fabrix. Chief Executive Officer Clive Nichol says the example proves it’s possible to “apply the circular economy to structural elements of buildings.” — Bloomberg Green
Fabrix has purchased 139 tons of steel from the contractor behind the demolition of One Broadgate and plans to use it on other projects in London. The process, known as urban mining, recovers and resells raw materials from waste products. Related on Archinect: How 'Anthropocene mining'... View full entry
Sustainability startup ByFusion has developed what they describe as “the first construction-grade building material made entirely of recycled, and often un-recyclable, plastic waste.” Named ByBlock, the interlocking blocks use the same principles as LEGO with protrusions on the top surface...

Why don't we re-use what we've already extracted, rather than gouging the planet for ever more raw materials? This thought has spurred a growing band of architects and building firms to look at how to re-use the huge range of materials already hiding within our built environment, from concrete and wood to the metallic bounty within electronic waste — BBC
Architecturally-rich cities are both a fount of reusable materials and a way of circumventing the awful cycle of environmental and human destruction caused by mining for the raw substances needed to help mitigate the effects of the built environment on climate change. Recent projects like the... View full entry
Bulgari is getting a timely makeover this holiday thanks to a green facelift from MVRDV. Using recycled champagne bottles, the Dutch firm was able to produce a dazzling new jade-like facade for the luxury retailer’s new Shanghai flagship.

Results of a new five-year study of recycled concrete show that it performs as well, and in several cases even better, than conventional concrete. Researchers conducted side-by-side comparisons of recycled and conventional concrete within two common applications -- a building foundation and a municipal sidewalk. They found that the recycled concrete had comparable strength and durability after five years of being in service. — Science Daily

Waste from construction and demolition sites accounts for approximately 15-30% of all landfill content in the United States. According to NASA's estimates, more than 500 million tons of often non-biodegradable building materials containing carcinogens and other toxins are sent off to the junkyard... View full entry
A prototype affordable housing scheme for post-Daesh Mosul by Weston Williamson + Partners has received an honourable mention in the Rifat Chadirji Prize. It was the only UK entry among the finalists. The prototype focuses on housing some of the city’s 900,000 internally displaced people who... View full entry
"Humanity went through stone age, went through ice age, and today, going through plastic age. We need to find solution,” explains Robert Bezeau, the man intent on amending the global reach of plastic waste by building houses out of it. A transplant to Panama from Montreal, he has started...

The [plastic] materials are thoroughly cleaned, before being ground into a rough power, mixed, melted and extruded into a range of shapes – mostly beams, blocks and pillars – which lock together to form buildings. Importantly, [Conceptos Plásticos] also trains communities in how to build these structures, giving them ownership over their homes [...]
Like LEGO blocks, these interlocking structures don’t need adhesive to be strong and sturdy, which makes them a good option for mobile shelters.
