New Biotech Converts Carbon Emissions into Protein-Rich Yeast with Vitamin B9 LINK

• Researchers in Germany have developed a "Power-to-Protein" system that converts CO2, hydrogen, and oxygen into yeast rich in protein and vitamin B9. Six grams of yeast meet daily vitamin B9 needs, while 85 grams provide 61% of daily protein requirements.

• This bioreactor technology runs on renewable energy and can produce nutritious yeast without using farmland, reducing carbon emissions and promoting sustainable food production. It offers an eco-friendly alternative to traditional protein sources like meat and plants.

• The team aims to commercialize this protein alternative by scaling up production, ensuring food safety, and addressing consumer preferences for taste and smell, while exploring regulatory challenges.

Microchips in Packaging Help Consumers Easily Identify Recyclable Materials LINK 

• UK start-up Pragmatic is developing silicon-free microchips that provide item-level intelligence for food packaging, helping consumers understand recycling regulations and whether packaging is recyclable by simply tapping it with a mobile phone.

• The microchips enable automated machines to sort packaging more effectively by identifying materials, allowing for the extraction of high-value plastics from waste streams, which enhances recycling efficiency.

• Pragmatic's technology allows manufacturers to track the recycling and reuse of their packaging, providing reliable sustainability data to shareholders and supporting initiatives like reusable packaging systems in supermarkets.

Reusable Glass Bricks from MIT Bring Circular Construction Closer to Reality LINK

• MIT engineers created 3D-printed, interlocking glass bricks made from recycled glass, offering strength similar to concrete for sustainable construction.

• The bricks' design allows for easy disassembly and reuse, promoting circular construction where buildings can be reassembled or the glass melted and reprinted.

• This innovation provides a flexible, eco-friendly alternative to traditional materials, making glass an ideal option for sustainable architecture.

Compact Wind Turbine Powers Laptops Quickly, Even Off-Grid LINK

• Aurea Technologies has launched a portable wind turbine capable of eco-friendly charging for mobile devices, working both day and night at wind speeds of 8 mph or higher.

• The Shine 2.0 can generate up to 50 watts of power, enough to fully charge a laptop in two hours, and includes a compact, foldable design, making it highly portable for outdoor activities.

• New features include a Bluetooth-enabled app for monitoring performance, a USB-C port for faster charging, and optional accessories for increased wind capture, with delivery expected by April 2025 through a Kickstarter campaign.

Recyclable Circuit Boards Bring New Life to Old Devices LINK 

• MIT, Meta, and University of Utah created a recyclable, low-cost flexible substrate for electronics, improving sustainability.

• The material uses light-curing tech to make polyimide recyclable, breaking down in mild solvents to recover valuable components.

• University of Washington’s vPCB allows reprocessing, recovering up to 98% of materials, helping address supply chain issues and waste.
