A dynamic combination of micro presentations and active collaboration to fast-track adoption of salvaged wood into mass timber.
In the ongoing search for building materials with the lowest embodied carbon and highest carbon storage capacity (that can be managed in a circular economy), the use of salvaged wood in finger jointed products/feedstock and mass timber assemblies keeps rising to the surface.
This summit will:
spotlight recent related innovations
identify key components and status of each
explore near-term opportunities for moving the effort forward
End of life disposal of building materials may also lead
to environmental emissions of PFAS. Large amounts
of waste building materials are disposed of in municipal solid waste and construction and demolition landfills, and leachate from both types of landfills contains
PFAS.255 PFAS-containing building products may also
be sent to municipal solid waste incinerators, which
have the potential to release PFAS emissions into air.
206 College Ave was deconstructed by the Circular Construction Lab. The materials were reused in Felix Heisel’s artwork Circulating Matters.
The Catherine Common’s project is being used as a case study for documenting deconstruction’s local potential. It is particularly useful as it permits a side-by-side comparison of demolition and deconstruction processes on nearly identical buildings within the same economic system. The Circular Construction Lab expects the generated data to provide a “much-needed insight” into the effects of implementing deconstruction and developing a business analysis that could address the scalability of the process.

“Though it may seem to laypersons that a postfire landscape is a catastrophe,” they wrote, “numerous studies tell us that even in the patches where fires burn most intensely, the resulting wildlife habitats are among the most biologically diverse in the West.”
But that hasn’t stopped federal agencies like the U.S. Forest Service and Bureau of Land Management from cutting trees burned in wildfires or selling the logging contracts to private timber companies.
It wouldn’t pay to build instruments and wait two centuries for them to become fully resonant before selling them, though Santa Cruz Guitar Company gains that advantage by beginning with really old wood. This aligns beautifully with the company’s decades long dedication to using reclaimed materials for both superior tone and environmental responsibility.
The bombs haven’t stopped Kovalenkov, who has launched “Hemp. Ukraine. Recover.”, a non-profit fund aimed at providing sustainable hemp housing solutions and psychological help for citizens and veterans affected by the war. The initiative’s centerpiece is a 30-unit apartment complex now going up near Morshyn, a small city in the western part of the country, specifically for refugee families and orphans.
Midcentury architect Bruce Goff built a plethora of organic buildings across the Midwest and beyond, combining imaginative forms with found and reclaimed materials, including ribbed Quonset huts, feathers and cullet.
Paul Kenyon started distilling gin during lockdown
He admitted that the toilets in St Martin’s Avenue had once been “terrible”, but it was also ideal for his distilling needs because it had drainage, electricity and water. After removing the cubicles, he had it redecorated with reclaimed materials, including tin from a friend’s farm and reused coffee sacks.
Furthermore, the idea of raising the park on its foundations came from the existing wooden piles in the water from old piers. Though disintegrating, these old piles have become an important habitat for marine life and are a protected breeding ground for fish. The designers wanted to mimic this for the Little Island.

Extending the life of existing structures, making them more efficient and reusing materials when properties are torn down offers one of the clearest paths for decarbonizing a sector that single-handedly threatens efforts to keep global warming within the 2C limit set in the 2015 Paris Agreement.
The Sir John Carling building implodes as it is demolished in Ottawa in 2014. The former government building was completed in 1967 and demolished at a cost of $4.8 million, but the bigger cost might have been the wasted energy invested in the building’s construction.

Demolishing an existing building, throwing it away in a landfill, is a staggering act of conspicuous consumption. And yet this destructive, extractive approach to Canada’s built heritage has been normalized over generations.
The ‘Pre-Landfill’ by Karlis Kukainis from Mackintosh School of Architecture
The Judges thought that this “playful project exhibits the art in architecture and shows that there can be fun beyond science”. It does this by testing the limits of reuse practices of reclaimed materials from demolished buildings which will be key to how we tackle the Climate Emergency.

Michel Baars thought he could do better than turn it into material for a road. Mr. Baars considers himself an urban miner, someone who extracts raw materials from discarded infrastructure and finds a market for them.
Scott Edouard Martinet worked in Paris for years as a graphic artist before turning to sculpture. His latest works use scrap metal mainly recovered from old cars, bikes and mopeds to create anatomically perfect animals.

The smartest infrastructure is a group effort, bringing together the collective knowledge and expertise of everyone involved: from developers, to development finance institutions, to private investors, project managers, suppliers, policymakers and impacted communities. This also means that if we want to build infrastructure that is both gender-smart and climate-smart, we need education, coordination and synchronization to make sure that everyone involved is fully on board with the benefits.
The city of San Antonio will implement a deconstruction ordinance aimed at reducing total demolitions of older, small housing and increasing deconstruction and repurposing certain building materials. (Courtesy city of San Antonio)
That focus will expand in January 2023 to single-family and multifamily housing built no later than Dec. 31, 1945. A third and final phase of ordinance implementation, beginning Jan. 1, 2025, will affect housing built no later than Dec. 31, 1960.
Rondo’s “brick toaster” heat storage system is 98% efficient, and stores cheap renewable energy for industrial use at 20% the cost of an electrochemical battery. Rondo Energy
These stoves are full of plain ol’ bricks, made out of plain ol’ clay, sometimes with a bit of sand in there, but certainly nothing special in terms of materials. Nothing toxic, nothing that decays over time. These bricks will still be storing heat just as well in 40 or 50 years’ time, when chemical batteries have gone through several generations of complex recycling.
Earlier this year, crews removed roofing, flooring and walls in a project that’s part of a Cornell University study comparing deconstruction and demolition. @ FitchyImages | stock.adobe.com
However, Felix Heisel, director of the Circular Construction Lab at Cornell, Ithaca, New York, told WSKG deconstruction can be cheaper than demolition when accounting for landfill diversion, reduced carbon dioxide emissions and fewer natural resources extracted since more materials are reused in deconstruction than in demolition.
Reclaimed wooden walkways and shared outdoor spaces make up a lot of the reclaimed Kha-Nam Noi House.
Thai architecture firm YangNar Studio recently completed “Kha-Nam Noi house” in the central province of Sing-Buri, Thailand, using an existing elongated pigsty as a shell for a series of comfortable living spaces made almost entirely with reclaimed materials.
Fast-forward to 2022 and it’s snowballed into an initiative where BARC goes into “homes otherwise set for demolition,” salvages as much lumber, pipe, wire, and other building components as possible, and then uses those reclaimed materials to build brand-new tiny houses throughout the Grand Traverse region.
Artist Bordalo II was in El Paso working on installing a large-scale mural on the One San Jacinto building in Downtown El Paso. This large mountain lion is part of a Big Trash Animals series of murals that he’s been installing all over the world using reclaimed materials.
Baltimore has been successfully running a similar program since 2016, and Philly officials have visited. In addition to milling old trees, Baltimore’s program also salvages wood waste from building deconstruction.
The Good Store “radically rethinks the department store”, with an emphasis on reuse and refurbishment. A range of plastic-free and sustainably sourced products are on offer, with the space also set to host informative educational events and services to guide consumers through eco-conscious choices.
Integrated sidetables were added to the lounge chairs
“People who sit in the chairs and touch the surfaces can ‘read’ the story of the furniture and understand where the materials came from. This connection to place and the playful character of the furniture is a powerful antidote to the usual impersonal, sterile environment of a hospital.”

Based in Lancaster, Pennsylvania, this company uses reclaimed materials to make flooring and surface products. Ecore International is the largest converter of reclaimed rubber in the continent, mostly using recycled truck tires.
Mel and Jez Wright are selling the custom home they created at 29 Highlander St, Torquay.
“I ended up ferrying 100 or so bricks in the back of a van and we’ve incorporated them into the walls of what we funnily call the rave cave,” she said.“It’s a space that we’ve created off the living area to house our music collection. And it’s got some thick sliding barn doors that Jez constructed from the wood that he’s collected over the years.

Production of cement, the raw material in concrete, accounts for between 7 and 8 percent of global carbon emissions today, due both to the fossil fuels used in its high-heat production and the chemical composition of the raw materials and processes that make it.
Reusing old wood, windows, metal, brick, and even concrete seems like a no-brainer (even some animals recycle used materials!), but it sadly doesn’t happen as often as it should. According to the Environmental Protection Agency, between 230 million and 530 million tons of construction and demolition waste are produced yearly in the United States.
Detroit the largest city in Michigan and has suffered a long period of economic decline with tens of thousands of abandoned buildings and empty commercial lots. It is also considered one of the unhealthiest cities in America due to food insecurity and the inability to find affordable nutritious foods.
