No cement. No steel. Minimal emissions. Maximum imagination. Bonus: Each brick stores carbon — about 0.8 kg CO₂ per 1 kg — making this a climate-positive construction method. In a world facing housing shortages, rising material costs, and a carbon crisis, this project makes us ask: What if construction could heal ecosystems instead of depleting them? What if our building materials were grown, not mined? The MycoHAB mushroom house isn’t just a novelty. It’s a signal of what’s possible when we let biology inspire building. NASA is even researching similar tech to grow habitats on the Moon. I’d love to hear your thoughts: Could you see fungi-based materials scaling up in your region?

Concrete is the second most consumed material after water. But it has a deadly weakness: it cracks... These cracks let in water and oxygen that corrode steel reinforcement, threatening structural integrity. This is where self-healing concrete comes in - the biggest breakthrough in construction materials in decades. The secret? Bacteria. Scientists use Bacillus subtilis bacteria that can survive concrete's harsh alkaline environment. During manufacturing, bacterial spores and calcium nutrients are mixed directly into concrete. These remain dormant until a crack forms. Then the magic happens: When a crack forms, water and oxygen enter. This awakens the dormant bacteria, which consume embedded calcium lactate. As they metabolize this food, they produce limestone and naturally fill the crack. The process works automatically, with no human intervention. It's like your body healing a cut, you don't direct cells to close wounds, they just do it. The results are remarkable: At Delft University, researchers saw cracks repaired in just 60 days. Even more impressive: bacteria-treated concrete showed 40% higher strength after 7 days and 45% after 28 days versus traditional concrete. The implications are enormous: • Eliminates expensive repairs and reduces maintenance budgets • Could help improve America's C-grade infrastructure (ASCE rating) • Reduces environmental impact as less new concrete is needed • Fewer repairs mean reduced environmental disruption We're entering an era of living infrastructure, materials that respond to their environment. This convergence of biology and materials science is creating entirely new possibilities for how we build. Self-healing concrete isn't just an innovation, it's part of a fundamental shift in how we think about the structures we rely on every day.

What Can We Do with Brick Waste? A Circular Approach Brick waste isn’t just debris—it’s a valuable resource waiting to be repurposed. Instead of sending millions of tons of bricks to landfills, we can reintegrate them into the construction cycle, reducing environmental impact and improving material efficiency. 1. Reuse in Facade Restoration & Construction • Deconstruction, Not Demolition – Salvage intact bricks for historic facade restorations or adaptive reuse projects. • Lime Mortar Separation – Traditional cement mortar reduces reuse potential, but lime-based mortars allow for easier brick recovery. • Architectural Feature Integration – Reclaimed bricks can be used for accent walls, decorative facades, and paving elements. 2. Recycle into Secondary Materials • Crushed Brick Aggregates – Used as a sub-base for roads, drainage layers, or lightweight concrete mixes. • Pozzolanic Additives – Finely ground brick dust enhances cementitious properties, reducing the need for Portland cement. • Clay-Based Insulation Panels – Processed brick fines can be reengineered into high-performance, breathable insulation materials. 3. Innovative New Uses • 3D-Printed Brick Components – Crushed brick powder can be reprocessed and printed into modular bricks for new facades. • Bio-Reinforced Bricks – Mixed with mycelium or hemp fibers, recycled brick can form sustainable, self-healing construction materials. • Carbon-Sequestering Geopolymers – Combining brick waste with alkali-activated binders creates cement-free, low-carbon masonry units. 4. Urban Mining & Circular Supply Chains • Material Passporting – Implement digital tracking of recovered bricks to facilitate reuse. • Citywide Material Hubs – Establish brick reclamation centers where contractors can source reusable masonry. • Deconstruction Incentives – Promote financial and policy-driven initiatives to encourage selective material recovery. Why This Matters • Reduces embodied carbon emissions by up to 80% compared to new brick production. • Cuts landfill waste, addressing the 25+ million tons of annual brick waste globally. • Lowers resource extraction, conserving clay and reducing mining-related deforestation. Brick isn’t just a past material—it’s a future-proof one. Let’s stop seeing waste and start seeing opportunity. #circulareconomy #brickreuse #sustainableconstruction #urbanmining #zerowastebuilding #adaptivereuse #facaderestoration #historicpreservation #brickrecycling #deconstruction #materialreuse #lowcarbonmaterials #greenbuilding #carbonfootprintreduction #sustainabledesign #buildingconservation #reclaimedmaterials #constructionwaste #embodiedcarbon #brickfacades #historicfacades #materialpassporting #geopolymer #crushedbrick #bioreinforcedbricks #netzeroarchitecture #sustainablearchitecture #greeninfrastructure #claybricks #futureofconstruction #lowembodiedcarbon #modularbricks #constructioninnovation #carbonsequestration

Using ceramic waste to help reduce the need for virgin clay in buildings 🧱 The Institute of Architecture and Design at The Royal Danish Academy has explored the transformation of brick construction waste into a new building material. Why? Denmark's subsoil is largely clay and has been an integral building material for generations. However, subsoil clay is formed over millions of years - and once it's gone, it's gone. In fact, Denmark actually *imported* $9.07M in ceramic bricks in 2022, becoming the 51st largest importer of ceramic bricks in the world, due in part to a domestic depletion of this non-renewable resource! 🤯 To explore ways to reduce the use of virgin clay in buildings, the project team crushed discarded bricks and mixed the aggregate with a binder to form a paste. The paste was pressed into moulds, fired, and finished in various ways. The outcome? New ceramic building products formed from a hyperlocal source - no excavating, mining, or importing required. While existing bricks are remarkably reusable just the way they are, I love this project because it helps demonstrate that a circular manufacturing process can combine beauty and practicality, just like existing linear supply chains - but the environmental impact can be so much less. ♻️ Would you install these circular ceramics in your own building project? Photos taken in April at the Form/Design Center in Malmö, Sweden. This project was one of six on display as part of the "Planetary Boundaries" exhibit, which explored building designs and materials that have a wide range of aesthetic use - but a tiny planetary footprint. --- 👋 I talk about circular economy in the built environment, including cultural heritage, workforce development, housing, and more.

Longevity of Ancient Roman Concrete Meets Modern Biochar: Engineering Self-Healing Construction Materials for Next Generation Resilience 2/12/2025 The remarkable durability of Roman concrete, exemplified by the 2,000-year-old Pantheon's dome, has long intrigued scientists. Recent MIT research (Self-healing Lime Clasts in Roman concrete, Science Advances, 2023 - https://lnkd.in/ejVJujdk) reveals that the secret lies not in simple material choice, but in an innovative "hot mixing" process combining quicklime with volcanic ash at high temperatures. This technique created lime clasts that enable self-healing properties - when cracks form, water triggers a chemical reaction with these lime deposits, forming calcium carbonate that naturally seals the damage. Reference Article: We Finally Know Why Ancient Roman Concrete Was So Durable PHYSICS 2/12/2025- https://lnkd.in/eGfNTrDw This discovery offers compelling parallels for modern sustainable construction using concrete particularly when considering the addition of high-pH, high-ash biochars derived from waste streams like biosolids and manures: 1. Similar Chemical Mechanisms - Like Roman volcanic ash (pozzolana), high-ash biochars contain reactive minerals that can form strength-enhancing calcium-silicate-hydrate bonds in concrete - The alkaline properties of manure-based biochars mirror the beneficial effects of lime clasts in Roman concrete 2. Self-Healing Potential - Biochar's porous structure and mineral content could enable similar crack-healing mechanisms to those observed in Roman concrete - When cracks form, moisture interaction with biochar's calcium and magnesium oxides may promote natural repair through mineralization 3. Environmental Benefits - Using waste-derived biochar as a partial cement replacement reduces concrete's carbon footprint - The pyrolysis/gasification processes sequester carbon while transforming problematic waste streams into valuable construction materials with environmental and economic benefits - This approach addresses both construction emissions and waste management challenges Commercial Momentum and Next Steps While biochars are already being incorporated into cement and concrete products, these new insights from MIT’s Roman concrete research suggest we should specifically investigate use of high-pH, high-mineral biochars from waste feedstocks for greater resiliency. This calls for continued advancement in both research and commercial applications to accelerate development and use of construction materials that match or surpass the remarkable durability of Roman concrete while advancing circular economy and sustainability goals. We’re in pursuit!

In the realm of structural engineering and design, the incorporation of advanced materials like FRP represents a leap toward innovative solutions that challenge traditional methods. I recently shared insights on utilizing carbon fabric, a type of FRP, to reinforce concrete structures such as slabs and walls. This lightweight, yet robust material, unidirectional in fiber orientation, offers substantial tensile strength while adding minimal weight to the structure. Its application is particularly transformative in seismic upgrades, where the goal is to increase resilience without significantly increasing load or complexity of installation. A fascinating comparison demonstrates that a mere 1.3mm thickness of this fabric, equating to less than two kilograms per square meter, can substitute for number seven grade 60 steel bars spaced six inches apart, based on their ability to withstand similar tension forces. This equivalence not only highlights the efficiency and effectiveness of FRP but also its potential to revolutionize how we approach structural reinforcement and repair. Imagine the possibilities - enhancing the durability and longevity of our buildings and infrastructure with minimal intrusion and weight addition, a boon especially in seismic-prone areas. The ease of installation further underscores its utility, offering a stark contrast to traditional methods like shotcrete, which significantly increases wall thickness and weight. This development underscores a broader movement towards adopting more sustainable, efficient, and innovative construction materials and methods. As we continue to push the boundaries of what's possible in engineering design, materials like FRP stand out as beacons of progress, offering new avenues for building safer, more resilient structures. #EngineeringInnovation #FRP #StructuralEngineering #SustainableDesign #ConstructionTechnology

Microsoft becomes a major force in driving construction sustainability with its recent agreement to purchase over 600,000 metric tons of a new type of #cement that is produced using less energy and produces fewer carbon emissions. It sets a high bar for owners of projects to commit to sustainability through bold commitments to innovative solutions by giving immediate legitimacy and widespread attention to a type of cement that is widely recognized, but is still undergoing scrutiny and sluggish acceptance. #Concrete is the most widely used material on the planet. The manufacturing of the cement used to produce concrete accounts for 8% of global carbon emissions. Efforts to lower the carbon footprint of cement are ongoing and widespread, but rely on strategies such as partial replacement of cement with other lower carbon products or through complicated “carbon-capture” schemes. While these remain relevant and important, the production of a new cement that is chemically the same as traditional Portland Cement but is produced without burning fuel and releasing carbon from the limestone (the raw ingredient) into the air represents a huge step forward. The cement to be purchased by Microsoft for future data center construction is produced to meet the requirements of ASTM C1157, while “traditional” cement is produced to meet the requirements of ASTM C150. The difference is that C150 is a prescriptive standard, specifying chemical and physical properties and emphasizing what the cement is made of. C1157 is a performance based standard that classifies cement by performance characteristics and not composition. While this encourages innovation and can lead to “greener” products, its like anything else that’s new…we don’t really like change in the #construction industry. While the FHWA has been encouraging states to consider acceptance of C1157 cement, only a handful of state DOTs have done so. While some states, such as California, also allow the use of ASTM C1157 in building construction as part of its green building codes and initiatives, the widespread adoption by one of the worlds largest companies for use in their construction projects will push and challenge others to do the same. In addition, think about this: Microsoft and other large companies that are driving data center construction have reignited the race to utilize nuclear energy in an effort to power these data centers. The process of producing traditional cement relies on burning fuel (typically coal or gas) to heat limestone in a kiln. This new cement is produced using electricity, meaning that in the future it is conceivable that cement plants using this process could also be powered by nuclear power plants instead of fueled by coal. #constructionishard #LIPostingDayJune https://lnkd.in/gFnmva5A

In a world grappling with climate change, Sweden is leading the charge with a groundbreaking initiative: constructing an entire city from wood. According to a recent article in The Economist, this innovative approach not only promises affordability and sustainability but also challenges our preconceptions about urban development. At the Institute for Development Impact - I4DI, we're inspired by such pioneering efforts and align with our urban development practice. Sweden's vision of 'timber cities' offers a blueprint for eco-friendly construction that could revolutionize how we build our urban environments. Wood as a construction material is undergoing a renaissance, thanks to technological advances that make timber buildings as fireproof as their concrete and steel counterparts. This shift towards wood is not just an aesthetic choice but a strategic move to combat urban carbon emissions. Trees absorb carbon dioxide during their growth, making wood a carbon-neutral resource when sourced sustainably. Sweden's commitment to building with wood is a testament to the potential of natural materials in creating the sustainable cities of the future. It's a model that encourages us to think differently about urban growth, prioritizing the health of our planet alongside the need for development. We at the Institute for Development Impact continue to support transformative urban development projects, and Sweden's example is a source of inspiration and a challenge to innovate. We are helping urban planners of today prepare more sustainable cities of tomorrow. #UrbanDevelopment #SustainableCities #TimberRevolution #ClimateAction

$4.5B has already been deployed to catalyze markets for cleaner construction materials. And it’s going to keep growing 👇 This comes from the Federal Buy Clean Initiative — a program that ensures federal projects will prioritize construction materials that are both American-made and produce fewer carbon emissions during manufacturing — and it could unleash unprecedented change in U.S. construction. Why does this matter? The public sector is the largest buyer of U.S. construction materials. When governments change how they buy, the whole industry shifts. $4.5 billion has already been deployed, which is still just a fraction of the federal government’s $630 billion total purchasing power. The potential for change is huge. But the fascinating part isn't the big numbers; it's the ripple effect, especially at the state level. This funding is creating opportunities throughout the entire supply chain: Regional suppliers are now getting recognized and rewarded for their environmental performance. Local manufacturing shops can compete for major infrastructure projects by measuring and improving their climate impact. Even small, family-owned operations are becoming key players in the climate solution. One example: • Port Authority of NY/NJ gets funding for low-carbon infrastructure • They need suppliers who can measure their footprint • Local concrete suppliers must adapt to compete • Local Family owned businesses suddenly enter the climate conversation Small manufacturers are becoming unexpected climate leaders. For many, it's their first step into sustainability, which is now a lot more possible because it comes with real economic opportunity. In other words, it’s a win-win. It creates market demand for green materials. It gives small players access to bigger projects. It turns local manufacturers into climate innovators. And perhaps most importantly, it helps democratize climate action. // The climate solution isn't just in Silicon Valley. It's in your local concrete plant. #construction #sustainability #manufacturing #climate
