New electrolyzer turns plastic-waste syngas into ethylene with less energy
For every ton of ethylene created, one ton of carbon dioxide is produced. With more than 300 million tons of ethylene produced each year, the production system has a huge carbon footprint that scientists and engineers are eager to reduce and eventually eliminate. A new device developed in Ted Sargent's lab at Northwestern takes a step toward breaking that cycle.

AI has delayed the planned retirements of at least 15 coal plants, some indefinitely: https://e360.yale.edu/digest/ai-coal-nuclear The head of the 2nd largest utility company in the U.S. says: "We're going to extend coal plants as long as we can because we need those resources on the grid." #energy #AI #climate

Bugs were supposed to be the future of food. Now, the insect farming industry is collapsing.

“We have to get used to the idea of eating insects.”
This proclamation came from, of all people, an insect researcher. Dutch entomologist Marcel Dicke pitched eating bugs in his 2010 TED talk as critical to sustainably feeding a growing human population, because insects have a much smaller carbon footprint than beef, pork, and chicken.
Spoiler alert: We di…

A 100% recycled paving block made from mollusk shells and mining waste
The construction industry is one of the most polluting due to its high contribution to CO2 emissions. In addition to its significant environmental cost, its materials are made from nonrenewable resources such as sand and gravel, making the search for sustainable alternatives an urgent challenge in a context where growing production demand must be balanced with environmentally responsible practices. The sector is therefore investigating the development of low-carbon-footprint materials within a …
