Food waste, wastewater, and the troubled battery industry in the UK • TechCrunch


Welcome back, climate technology readers! Likes last weekAgain, we’ve got a whole list, from food waste to sewage and more. Let’s dig deeper.

After, after Selling Nest to Google For $3.2 billion, Matt Rogers is no stranger to rapid expansion. But unlike last time, Rogers wasn’t interested in selling so quickly. “This is the next 20 years of my life. This isn’t like, building the company in four or five years and selling it to Google. This is a big, long journey,” he told TechCrunch.

Rogers seeks to end food waste, which accounts for 6% to 8% of all greenhouse gas emissions, and his tool for doing so is the humble kitchen trash can. Sleek and technology-enabled, the Mill Industries container dehydrates and grinds food until it resembles powdered coffee. Then, when it’s full, it automatically orders a box to mail the dried leftovers to one of Mill’s facilities, where it’s made into chicken feed. how do we get there? this part Rogers was even more surprised.

Industrial facilities from semiconductor plants to auto plants use staggering amounts of water. What appears on the other end can be difficult to remedy and even more difficult to reuse. This is why Membrion has developed a ceramic membrane that can filter out heavy metals such as lead, arsenic and lithium. startup $7 million in a Series B round It hopes to bring in another $3 million.

Britishvolt has always been elusive, but the battery start-up seems to have missed its mark entirely. This week, it announced it would file for bankruptcy, after making little progress on its planned $4.7 billion plant.

The company’s downfall echoes what happened here in the United States just over a decade ago when A123 Systems stumbled and filed itself into bankruptcy. But the British version of the story may not have a happy ending. With the A123, the United States had enough time to cover. With the solidification of global battery supply chains, The UK’s domestic battery industry may never catch up.

Space programs pride themselves on developing far-reaching technologies that are proving valuable here on Earth. Apollo helped catapult computing, and the space shuttle did wonders for avionics and materials science. Now, it’s Perseverance’s turn on the Mars rover.

The MOXIE experiment was built to prove that carbon dioxide can be converted into oxygen on Mars. Chris Graves, who worked on the machine, thought it could help tap the Earth’s carbon dioxide, so he started Noon Energy. The company’s carbon-oxygen battery promises to store electricity for long periods at a fairly low cost. The startup announced $28 million Series A this week.

Heat pumps and household energy retrofits have received a lot of attention as a result of incentives in the Inflation Control Act. This makes it a good time to be sealed. The company predicts how much energy a retrofit will save and shifts installation costs in advance, billing homeowners based on the savings.

For a company that relies heavily on data, Sealed has acquired Burlington, Vermont-based InfiSense. Makes sense. Neither company disclosed the terms of the deal. Sealed plans to offer customers InfiSense sensors, though not requiring them, to monitor energy use and indoor air quality.
