In the urban mines of tomorrow, gold will be extracted from old computers, not ore; cotton will be harvested from well-worn shirts, not fields; and cobalt will be processed from broken flatscreen TVs, not acid-rinsed from a million tons of rubble. If this all sounds like a pipe dream, note that the medals at the Tokyo Olympics are made of gold, silver and bronze recovered from the nation’s e-waste.

“One of the ‘ah-ha’ moments was not to focus on high school seniors and young women,” Hoffman said. “Across the country, we’ve learned that many women make the choice to enter the trades in their mid-20s to mid-30s.” “They’ve been in the labor market. … They may have been in low-wage service jobs,” she said. “They are ready to look for something new, something that is high-paying because they may be needing to support children, and they are looking for the future.”

“This will be a model of best practices for our country,” he said expansively of the new facility, citing the innovations and new technology it put into practice. “It’s great for addressing climate change through all the methane that won’t go into the air, the renewable energy we’re getting out of this, and the ability to divert trash from the landfill without the necessity of expanding it.”
Pittsburgh officials aim to remove blight in neighborhoods by deconstructing city-owned properties that are condemned but not slated for demolition. The deconstruction will involve stripping buildings of useful materials to preserve their integrity so that they can be used in other building applications, according to the city.

In 2016, it was reported that the four dams were producing on average over 1,000 megawatts of energy each year – or enough to power 800,000 American homes. But as the renewable energy sector continues to shift and hydropower competes against low-cost renewable energy, including solar and wind, there is some uncertainty when it comes to what the future will look like for the industry. Against this backdrop, more than $17bn has been spent in recent decades as part of federal salmon recovery efforts.

If the dams remained, PacifiCorp would likely have to spend hundreds of millions of dollars to retrofit the structures to comply with today’s environmental laws. As it is, the utility has said the electricity generated by the dams no longer makes up a significant part of its power portfolio.
This is the 3rd video in the Strong Towns series, and is probably the most important core topic: the fact that American car-dependant cities are financially insolvent, and function like a Ponzi scheme. This is the reason most American cities are bankrupt.
“Carbon emissions from dams had been significantly underestimated,” wrote Matthias Koschorreck, a biogeochemist and the study’s senior author, in a press release. Where climate policymakers had once considered them a carbon sink, he argues, they should now be thought of as a source.
Governor Newsom, Cal Fire, and the California Natural Resources Agency continue to pay lip service to the climate emergency while promoting commercial logging and road building as appropriate responses to the wildfire crisis. They spend millions of dollars on a PR campaign for Nature-Based Solutions, but move forward with business as usual, promoting and approving the logging of millions of acres across the state, burning massive quantities of fossil fuel just to destroy our best ally in our fight to have

Ever wondered what happens to all your stuff when you throw it out? A lot of it – from sauce sachets to mobile phones – ends up in landfill or gets burned. Or it ends up in our environment, causing damage to the natural world on which we depend.
Since 2015, London-based Growing Underground has been using one of London’s eight underground World War Two bomb shelters to grow fresh produce indoors in an environment where no pesticide is required.
“I’ve seen the economic development happen to our community — it’s frustrating on a local level,” he said. “But, at the same time, I see a regular list of articles about Amazon building here and Amazon building there. I’m not sure any of us really fully understand the implications because it’s happening so so fast.”
“Trees are nature’s technology to handle carbon removal,” says Jackson, who was the Administrator of the U.S. Environmental Protection Agency from 2009 to 2013. “We want to show how to do it the right way, and we want it to be profitable.”

‘Natural forests are not renewable. Trees can be planted, but not forests.’ They added: ‘If you plant pine trees, you get a timber field, not a forest. Real forests are complex ecosystems, a bedrock of a multitude of life and home for many species’
As manufacturers are working to reuse their waste products — both through upcycled products that save food items from the trash and manufacturing processes that use waste for energy — a successful test result could put Kraft Heinz in a class of its own. The company could potentially renovate its factories with its own post-consumer waste, which would be impactful.
Engineered by 3D printing specialists WASP and designed by Mario Cucinella Architects, the first prototype of TECLA in Ravenna is built entirely using reusable and recyclable materials.
By becoming the first eco-habitat to be built using Crane WASP (world’s first modular and multilevel 3D printer designed to collectively build singular and large-scale architectural works), the structure takes inspiration from potter wasp, founded on the principles of a circular economy and digital fabrication.

More than 90 per cent of the 230,000 tons of construction waste ReEnergy accepted in 2019 came from out-of-state, according to its annual report. After processing, ReEnergy said it sent 93 per cent of the imported trash to the Juniper Ridge landfill, which while owned by the state is operated by a private company, New England Waste Service of Maine, a subsidiary of Casella Waste Systems. Casella collects a “tipping fee” from ReEnergy for taking its waste. Fees for construction and demolition debris vary, but range from US$33 to US$95 per ton, according to the state’s environmental agency.
The consultant, Tap International, says the Construction and Demolition Waste Diversion Program Program needs improvement to ensure that the City’s requirements and the intentions of the program are met.
In December 2020, Victoria council voted to approve an ambitious plan to reduce city waste by 50 per cent by 2040. “If we diverted all the construction waste currently going into the landfill, that would take us 10 per cent of the way to our targets,” said Helps. In an effort to cut red tape for companies like Unbuilders, city staff are in the final stages of drafting a deconstruction bylaw.
Some of these interventions are so sensitive and surgical that they might be seen as prototypes for similar spaces all over the world, making a case for reusing structures instead of tearing them down.
The yellow pine that was used to build Baltimore’s rowhouses came from old-growth forests, and is more dense and rot-resistant than faster-growing new lumber; a century of oxidation has given it a handsome, dark patina. Furniture-makers and interior designers play up its provenance, designing items around its joist- and plank-shaped pieces, some of them pocked with nail holes and saw marks.

Reichert said it would only be fitting to have lumber from the home recycled as furniture since Massier and his father and brother worked as furniture makers at Kroehler Manufacturing Co., which was once Naperville’s largest employer and, in the 1940s, the second-largest furniture maker in the United States.
There has also been a shift towards repurposed or ethically sourced, natural materials. “Homeowners should keep this in mind when doing any renovations. Over time, likely, homes with environmentally friendly features, such as built-in cupboards made from reclaimed wood, solar panels, water-saving faucets, will become increasingly desirable, especially among younger buyers.

“Any sustainable waste plan must include efforts to actually bring down waste,” said Abena Asare of Brookhaven hamlet, a member of the Brookhaven Landfill Action & Remediation Group. The community group supports alternatives to landfills that they say disproportionately are sited in minority and low-income communities.

“We’ve been talking behind the scenes about how to infuse our preservation work with this mindset, and of course preservation is an inherently green practice, particularly with adaptive reuse of old buildings. So, this really gave us a great way to marry preservation and sustainability. It just gave us a great jumping-off point.”
Climate change is the one of the most important issues of our time. Yet most of us don’t know how to think about it or what to do about it. I’ve made this site as an outlet for my thoughts on and journey through this topic, specifically within the context of the building industry — an industry that fascinates me because it is so tied to who we are as a modern society and because it has enormous potential to reduce environmental impact on a global scale.
The Forest Service is eager to support efforts to reclaim wood because it means fewer trees will be felled; it now coordinates with the city of Baltimore to identify properties destined for demolition and sends in crews from companies with expertise in deconstruction, including Brick+Board.

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.

If you are donating a “whole house” the house will be relocated off your property. Otherwise you are donating pieces of the house. Material destroyed in the deconstruction is not part of what you get credit for in valuing your deduction.

Building deconstruction greatly reduces the amount of dust generated and prevents the spread of airborne contamination. Deconstruction of the former production building and disposal of the debris is expected to take approximately seven months.
“I know it might seem small to you but to get two pallets of napkins I’m not gonna have to buy napkins for two years from the Salvation Army and we serve more than 300 meals a day,” said Captain Andy Miller, the area commander of the Salvation Army in Tampa.

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.
This Swiftwater Films time lapse, produced by director Shane Anderson and filmed and edited by Jesse Andrew Clark, shows the monthslong process of deconstructing the Nooksack Dam on the Middle Fork of Washington’s Nooksack River. This restoration will repair 16 miles of habitat for threatened salmon and steelhead.

Across Canada, about 84 per cent, or four million tonnes of construction waste, ends up in landfills each year. Even in a forward-thinking jurisdiction like Metro Vancouver, less than one per cent of construction and demolition materials are reused. With the deconstruction industry in its infancy, the pandemic recovery is a chance to foster its long-term growth.
