Researchers at the University of Maryland have turned ordinary sheets of wood into transparent material that is nearly as clear as glass, but stronger and with better insulating properties. It could become an energy efficient building material in the future.
SQ4D’s completed proof of concept and demo home. SQ4D says it is the world’s largest permitted 3D printed home at 1,900 square feet.
“The cost of construction is 50% cheaper than the cost of comparable newly-constructed homes in Riverhead, New York, and 10 times faster,” said Stephen King, the Zillow Premier agent who has the 3D house listing. The 3D printed house will include 1,407 square feet of living space and will be built with concrete.

Despite the recycling success, however, the steel industry is increasingly facing pressure to decarbonize. Recycling steel is still both energy- and cost-intensive, and both steelmakers and their customers must go further to reduce environmental impacts. One way to do this is to shift to a reuse model.

Nine of the buildings to be demolished were built between 1929 and 1970, according to G-P’s demolition plan. They include a two-story, 31,360-square-foot development lab; a four-story, 31,000-square-foot nonwovens manufacturing building; a three-story, 11,000-square-foot office building; a two-story water treatment building; two warehouses; a 3,500-square-foot library; and a one-story microscopy laboratory.
“By effecting a step change in how we use and reuse resources, the move to a circular economy will deliver major environmental and economic benefits and is an essential element of making net zero a reality.”
This study suggests that salvaged lumber could potentially be a new source of raw material for mass timber products, which could create new opportunities for wood waste recovery and greener building products.
Salvaged lumber from Portland deconstruction practices was collected, graded, and processed for mass timber panel manufacturing.
An analysis shows that raw materials are more likely than composite materials to be sourced from child or forced labor, with precursors and minerals posing the most risk. Furthermore, the data delves into the connection between logging practices and slave labor in certain countries, noting that a staggering 80% of timber from Russia and Peru is reportedly harvested illegally, often through exploited or trafficked workers.
The collaboration with ReTuna will help IKEA understand why some IKEA products are turned into waste, what condition they are in when thrown away, why do people choose to donate or recycle products, and if there’s an interest in buying the products that have been repaired.
For example, it changes the layout of the structure and it optimally selects and positions elements from existing stocks to further reduce the structure’s carbon footprint, it limits the number of new cuts and keeps the number of components to a minimum.
“Once materials – raw materials – leave the biosphere and enter the technosphere because they are processed, we need to keep them in the technosphere and recycle or reuse them as much as possible,” Pralle said. “For that we need to create a deconstruction industry as powerful and elaborate as the mining industry.” Pralle said the success of a deconstruction industry
The B-Wa (h) renhaus with its shop-in-shop range of used goods is also a unique project nationwide. It is an important step on the way to ‘department stores of the future’, which offer attractive shopping opportunities for used goods. As part of the Re-Use initiative, three to four “used department stores of the future” are to be built in Berlin in the medium term.

Berlin hopes to use the stores to “anchor the re-use of used goods in urban society” by functioning as centers to educate and spread tips on re-use — especially to sections of the public that aren’t currently much involved in the circular economy. The initiative is part of a broader plan from Berlin’s ruling center-left/Green/left coalition that looks to slash waste in all areas of the city’s economy.
Holly Springs resident Mark Whitlock used his over 30 years of experience in the salvaging business to construct a building from mostly recycled materials. This building is the first new one in the Town Center District.
“All of the floor has been reclaimed out of a building in Pennsylvania, which used to be a part of an old school house,” Whitlock said. “A building in Kentucky was taken down by a fire, so I salvaged about six tractor trailer loads of it and turned it into furniture. I also brought back 13 tractor trailer loads of lights and light fixtures from Texas to use to create my own light fixtures. Every light fixture in the house was made from these materials and the ones I didn’t use for the light fixtures in my h
Sales of the used, bright yellow vehicles, called “skoolies” by their owners, have risen in some markets during the recession as more Americans shift toward a nontraditional, more affordable and socially distanced way to live.
“The good news is that—as we’ve seen in the past two decades with Clean Energy—strong leadership with a clear vision can pay off for the Northwest in big ways: hundreds of new Clean Materials businesses, thousands of new jobs, and billions of dollars in new investment. At the same time, we can slash the emissions that are driving climate change and reduce toxic pollution.”
“Yeah, we have one of those,” Byrnes said with a laugh. “It was for a giant. And it will be for other large items: back bars, theater lighting, airplane wings, floor boards, things like that. I like to joke that we could fit a double-decker English bus in there.”
Skanska’s Jimmy Mitchell has been a strong advocate for salvaged building materials for more than a decade.
From Long Beach to Boston, a new generation of organizations has grown up around the deconstruction of buildings and the sale of reusable materials. They’re often nonprofits backed by local architects, builders and environmental groups. Their aim is to build a supply chain that puts salvaged goods on equal footing with new products and materials.

Different types of wood aren’t the only thing Raymond seeks to salvage from assorted online sites. He also finds windows, appliances, tiles and fixtures. Recently, Raymond had a lead on a slate sink that slipped through his fingers.
“Salvaged from old buildings or junkyards, these items ensure a home’s uniqueness,” says George DeMarco, real estate agent with Halstead Manhattan, “and can boost resale value if done well. Walking into new construction and seeing a blast from the architectural past often can make just enough difference in the buyer’s mind to help make the sale.”

“Whatever you are going to construct, from an environmental perspective, your number one priority is to ensure your designers are focused on enabling you to build something that is energy efficient, uses materials that have a low embodied carbon and can be easily maintained, re-purposed and ultimately, after a long and useful lifetime, be recycled,” Dominic Burbridge, associate director of the Carbon Trust, said in a statement sent to CNBC.com.
Isaac Brock’s Oregon home is a hit. Records show the Modest Mouse frontman sold the 111-year-old Craftsman for $1.09 million, finding a buyer after just a month on the market.
A 2017 UN Environment report estimated the building sector contributes 49 percent of global greenhouse gas (GHG) emissions thus making it the single largest contributor to climate change. Globally, building operations account for 28 percent of GHG emissions and the embodied carbon of building materials–the emissions generated in the production, transport, and assembly of materials such as wood, concrete, and steel–accounts for another 11 percent.
“We’re seeing these forests disappear overnight. It’s happening so fast, and there’s very little old growth left in this part of B.C. It’s an environmental crisis that’s no less tragic than the loss of coral reefs and tropical rainforests.”

Slabs of wood this large can match or exceed the performance of concrete and steel. CLT can be used to make floors, walls, ceilings — entire buildings. The world’s tallest mass timber structure, at 18 stories and over 280 feet, was recently built in Norway; there’s an 80-story wooden tower proposed for Chicago.
‘To me, this indicates the need to further question the current practices of the construction sector. How is it that something so simple and obvious as keeping reusable resources intact and in circulation can have become so complicated to put into practice?’
“We are already selling pieces from the hotel’s interior on our website. Items for sale include light fixtures fashioned from Venetian glass and French crystal, along with more than 40 marble mantels carved in a variety of styles, including a $40,000 inlaid marble mantel from the US Ambassadors Suite. More affordable items include steak knives ($25), polished bronze swan hook ($45), stainless steel slotted egg spoon ($20), and a steel ice scoop ($10),” added Browne.
The Tilia version is made of dark linden wood, and the Salvage version is made of an airy and lightly recycled spruce wood. In both cases, the headset uses a dual 3.5mm jack layout – one per side.
Reclaimed timber—the entryway alone used more than 2,000 pieces of reclaimed timber. Art installations made from 85 percent repurposed construction waste, recycled and diverted from landfills.
Because the vacant buildings anchored Main Street, their rehabilitation would signal that things downtown were changing for the better. And by repurposing the former hotel—once a jewel of the area—they could connect Rawlins’s nascent entrepreneurial ecosystem directly to the community’s history and distinct sense of place.
Homeowners love features that come with a story, says Rich Ellis, publisher of Architectural Salvage and Antique Lumber News. “When you can point to your floor and say it came from an old shoe factory in Connecticut, for example, that’s a big attraction,” he says. There are between 500 and 700 architectural salvage businesses across the country, and business has been good, he says.
The Solid Waste Division (SWD) strives to enhance the efficacy of Construction & Demolition (C&D) recycling. SWD is offering a new $700,000 C&D Grant Program for innovative projects that support King County’s Comprehensive Solid Waste Management Plan (Comp Plan). As established in the King County Strategic Climate Action Plan (SCAP), King County aims to divert C&D materials from landfills at a rate of 85 percent by 2025, and also has a countywide goal of zero waste of resources by 2030.
The project will see over 1,000 homes demolished and materials reused. Based on an initial assessment of the regeneration project, the scale of benefits that may be realised through comprehensive implementation of Clarion’s circular economy strategy are significant.
Europe is anticipated to account for a significant share of the global construction & demolition waste recycling market. The region is estimated to be followed by North America. Demand for construction & demolition waste recycling market in Europe is rising due to the increase in awareness about environmental protection and government regulations on landfills and promotions for recycling. Asia Pacific also offers significant growth potential for construction & demolition waste recycling, as the building & c
The house’s owner was told by a man who worked in a local salvage yard that the wood for the kitchen’s window seat was used in the building of the Titanic.

As resources become scarcer, building owners may one day be able to sell walls, ceilings and floors to other developers, instead of demolishing them.
In practise, circular construction is all about the “connections, joints and system layers,” says Guldager Jensen. For example, windows might be attached using a mechanical method rather than glue, or lime mortar might be used rather than concrete mortar.“It’s about being able to think about the mechanics and being able to do it in reversible ways.”
“I was able to make a deal with him to purchase this material,” he said. “With diligent deconstruction efforts, we were able to reclaim approximately 15,000 board feet of beautiful, circle-sawn heart pine lumber.”

The store’s goal is zero waste: everything produced can be recycled, composted and repurposed while highlighting the local, creative market with people and resources from the community. “It keeps more money in our local economy so we’re more socially responsible, but also it uses [fewer] resources when you’re purchasing local-made stuff as opposed to imports, so better for the environment long term,” Work said.
Material passports specify the position, availability and value of the materials in your buildings. They support the circular economy by making it easier to identify and reuse products, tapping into inherent value rather than squandering it and starting from scratch. Instead of ‘crushing buildings into pretty useless rubble,’ as circular economy expert Duncan Baker-Brown of BBM Sustainable Design explains, material passports make beneficial deconstruction, or even keeping a building, more likely.

Mr. Pallrand’s master bedroom is paneled in redwood that Pacific Redwood culled from a decommissioned bridge built in 1925 in Humboldt County, its knotholes and bolt-holes still visible. The Philippine mahogany table, now carved with a mycelium-inspired runner down the center, was hewed from 1920s-era church pews that a congregation in Santa Monica, Calif., was dumping.
One benefit of shopping salvage: the pleasure of having part of your home remind you of your childhood home, perhaps helping your grandmother make cookies or sitting by a fireside on a brisk evening.

“We jumped at the opportunity,” said Sam Constantine, co-founder and co-owner of The End Grain Woodworking Company , which makes products using old wood from buildings throughout Detroit. “Each piece has its own story, and we make sure it continues to be told instead of getting lost in a landfill.”
Deconstructing history isn’t easy. Turney puts hours of sweat into the process, prying out rusty nails that haven’t budged in more than 50 years.This is the second Quonset hut he’s helped reclaim in the past couple years. The patinaed metal will be a huge hit in his Palmer store.“Some people use it as wainscoting or on the trim of a bar,” he said.
Examples of grant project ideas are creating a pilot reusable to-go container service program that partners with regional takeout restaurants or launching a construction and demolition building materials reuse program.
The Board of Selectmen approved an agreement with a salvage company to take items, including the front door and door knocker, from the house at 35 Wolfe Ave. in Beacon Falls, known locally as the Tracy Lewis House, for $3,000. –LUKE MARSHALL
While the items may fetch more money than the company is paying the town, officials said there’s no other proposals on the table. “We have nobody knocking on the door to go in and do anything,” said Selectman Michael Krenesky, who was named custodian of the house in 2014.
