If all goes well, a cleaner and more cost-effective solar recycling process could reach the market right as the first wave of solar panels hits the waste stream. “As we’re ramping up clean energy manufacturing, producing more clean energy tech, thinking about recycling at the end of life becomes even more important,” says Diana Bauer, acting deputy director of the Advanced Manufacturing Office at DOE.

Today, cooking one ton of cement yields nearly a ton of CO2, and concrete plants pump out nearly 8 percent of the world’s carbon emissions. Since an ever-growing population can’t wean itself from its primary building material, warding off climate change is going to require a cleaner way to make it.
For reference, the current “tallest tree” in the world is said to be Hyperion at roughly 380 feet tall. Today we will focus on trees (with measurements given) from the 1800’s that stood over 400 feet tall (and take a look at their unique photographs).

On 4 October WindEurope CEO Giles Dickson visited Holcim’s Lägerdorf plant in Germany, together with Claudia Grotz of Siemens Gamesa and Chair of WindEurope’s Sustainability Working Group. They met the Geocycle team who are using wind turbines blade waste to generate heat and ash to help make cement. It’s currently the only such cement plant in Europe that’s using blade waste.
The organic content of blade waste is recovered as thermal energy while the mineral fraction of the waste is integrated as ash in the matrix of the cement clinker the plant produces. This reduces the carbon footprint of cement production and makes it more resource efficient. This is because the blade waste substitutes (partially) for fossil fuels in the incineration process and for other materials in the clinker production process. One tonne of blade waste reduces CO2 emissions by 110 kg and saves 461 kg of raw materials.

The story of Harvard suggests that lax U.S. laws around shell companies and real-estate purchases, in addition to a broader lack of regulatory oversight, may be putting America’s heartland in the crosshairs of elites like Kolomoisky. It’s a reality of global corruption that U.S. lawmakers are only just starting to grapple with: As money-launderers and illicit financiers hide their money in the American Midwest, they’ve become part of the story of the decline of small-town, blue-collar America.
The Singer building was one of the worlds most beautiful examples of urban architecture – now it is an example of poor historic preservation.
According to the US Environmental Protection Agency, approximately 11 million tons of asphalt roofing shingles are disposed of each year, contributing to over a million tons of waste produced by the roofing industry and companies are increasingly looking for methods to both offset their carbon footprint from re-using single-use products and find environmentally-friendly sourced products for their businesses. Landfills across North America are already over-crowded. Single-use asphalt shingles do not biodegrade or decompose and will sit in landfills for hundreds of years.

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 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.

Hemp is lighter than traditional aerospace materials (such as aluminium and fiberglass) and therefore requires a lot less fuel to reach a high altitude. Most importantly, hemp is non-toxic, sustainable, requires way less water and land to grow than cotton, and compared to steel or carbon fibre, has almost no environmental impact.

Aspen City Council has committed funding for a comprehensive waste management plan to provide incentives for recyclable and compostable materials to be diverted from the landfill.
She also told the council that unlike other communities that may benefit from a public-private warehouse that could give construction materials a new life, the local market is not in the mood for second-hand materials. “The concept of taking someone else’s used building materials and using it in a new construction project, the audience for that is limited,” Chapman said.
“In general, we’re just trying to be strategic with how waste is handled and processed on-site so that it’s safe, we’re compliant to regulations, and people really take pride in the Yellowknife landfill.”

This allows the material to be shaped into tubing, coatings, bumpers, insulation, and many other things you’d normally find made of rubber. But the important thing is that this isn’t the end of the story. Once these products have worn out or are no longer needed, they aren’t just thrown away – the rubber can be ground up into powder, placed back into a mold, and recycled into something new.

The construction industry — from the mining and smelting of raw materials to dealing with the waste from demolished structures — has a huge environmental footprint that is often overlooked. It produces 11% of global greenhouse gas emissions. That’s a staggeringly high number, four times the emissions of the whole aviation sector.
