America has a garbage problem, but it is not without a solution. It is a testament to innovation that a company known for single-use products is championing a new way of dealing with waste.

Eggs found to remove salt and microplastics from seawater
"Other proteins also worked indicating that the material can potentially be produced in large quantities relatively cheaply and without impacting the food supply. Now, the researchers are focused on refining the fabrication process so it can be used in water purification on a larger scale."

Accelerating climate-smart practices on U.S. dairy farms
"In addition, the solutions to dramatically reduce U.S. dairy’s GHG footprint, including methane, are emerging and largely exist. These practices include a host of interventions such as digesters, which convert methane from manure into renewable natural gas; feed additives to help minimize the effect of enteric ("cow burp") emissions; energy efficiencies across dairy operations; and regenerative farming techniques that can improve soil health and potentially capture carbon in the soils."

Pacific Northwest is a hub for fusion companies chasing power’s ‘holy grail’
"To create fusion, one must first generate a plasma — a superheated gas and the most energetic of the four states of matter — where two nuclei smash into each other, forming a new atom and releasing energy. Plasmas are created in a wide variety of devices that can reach temperatures hotter than the sun and must contain the reactions for a sufficient amount of time. The energy given off by the reactions is captured and converted into electricity."

Carbon Re spins out of academia-land to take on cement pollution
"Planet A Ventures, a Berlin-based climate tech venture capital firm, led the £4.2 million round, with participation from Clean Growth Fund, UCL Technology Fund and Cambridge Enterprise. The new investment will enable Carbon Re to focus on rolling out its product to the global cement market. The next target the company has set itself is to expand into other energy-intensive industries, such as steel and glass."

This Material Could Reduce CO2 From Coal Plants After Record Emissions Last Year, Study Finds
"36.3 billion. That’s how many tons of carbon dioxide were emitted worldwide in 2021, according to the International Energy Agency. It’s the highest level ever recorded and represents a 6% increase from the previous year as the world economy bounced back from the Covid-19 pandemic slowdown."

There are 280 billion tons of mining waste. This startup is putting it to good use
"Now, it’s working to partner with mining companies that want to get rid of waste (and potentially, in some cases, remediate old mining land so that it can have other uses, like a park). It’s also targeting old mines where waste has been sitting for decades—or even as long ago as the 1880s. Because it starts with waste,and doesn’t have to invest in drilling into the earth,the cost of the final materials can compete with minerals from polluting mines in China and other countries."

Engineers developed a breakthrough method to generate hydrogen gas in one-step process
"In comparison, current catalytic technology refineries work through a method known as the Claus process, which requires multiple steps. Also, it produces sulfur but no hydrogen, which is converted into water."

This startup seals your leaky home so you waste less energy and reduce your bill
"The system is relatively simple, and akin to fixing a flat tire. It first pressurizes the ducts or building envelope with a fan, then injects micron-sized particles, which, as they try to escape the building or any space, automatically adhere to the gaps and seals them. The particles are made of a non-toxic, non-flammable emulsion of water and vinyl acetate, according to the company, which adds that these are some of the same ingredients found in pacifiers and chewing gum."

Meet The Entrepreneurs Who Designed Pollution-Killing Plants
"The actual plants will be far larger once they’re ready for sale. The Neo P1 sits on a custom-designed tall stand that both maximizes its air-cleaning properties and allows it to be watered far less often. Initial testing, conducted in partnership with Ecole Mines-Telecom of Lille University, showed the new plant was up to 30 times more effective at removing VOCs from the air than the most efficient plants found in nature."
