New concrete recipe enables the material to absorb CO2 twice as fast
Concrete is the most widely used material in the world. And as you might know already, it’s also one with a gargantuan environmental footprint, producing over eight percent of the world’s CO2 emissions. What’s less known about this binding material, however, is that it can also capture CO2 Read More...
Could mushroom bricks replace cement bricks?
A tenth of global carbon emissions is made up of building materials and construction. That’s why engineers are in search of better alternatives to polluting materials such as cement bricks, which require a whole lot of energy to produce and winds up in the landfill at the end of their lifecycle. Read More...
Elon Musk announces $100m competition for carbon removal technologies
Carbon capture technologies have proven their potential to help accelerate the transition towards a post-carbon future. But one of the main problems preventing the solution’s widespread implementation is that the tech is still relatively expensive and unproven at scale. In a bid to foster Read More...
France introduces “repairability index” to bring circularity to electronics
These days it’s all too common to have a drawer of discarded cell phones and other broken electronics in our homes, but if we want our economy to become truly circular, we will have to come up with innovative ways for these electronics to be repaired and reused when they get damaged. To achieve Read More...
Student science project convinces school district to switch to electric buses
Miami-Dade County Public Schools will convert all their diesel school buses to all-electric models by the end of 2021. This change has great environmental and public health benefits, but it wouldn't have happened without the help of Holly Thorpe, a local middle school student. Thorpe created a Read More...
Scientists use renewable energy to turn CO2 and water into synthetic fuel
While we work towards a future where all vehicles are electric, it's important we find greener ways to fuel the combustion vehicles in service today. With that in mind, researchers have figured out a way to make fuel for gas-burning cars using renewable energy. The novel process involves combining Read More...
New process separates fabric microplastics into harmless CO2 and H2O
We recently shared a story about balls of seaweed that help collect plastic from the seafloor, but the question still remains, what do we do with this plastic once we collect it? Researchers from Quebec's Institut National de la Recherche Scientifique (INRS) may have an answer with their new Read More...
The surprising reason you should turn your camera off during Zoom calls
To all of you who have been keeping their cameras off during Zoom calls, well done. You may have simply been trying to hide your face, but what you might not have realized is that you were drastically cutting your carbon footprint. In a new study, researchers analyzed the environmental effect Read More...
AirBird is a smart sensor that alerts users when indoor air quality is poor
While we often hear about the dangers of heightened CO2 levels in the atmosphere, a high indoor concentration of this greenhouse gas can also have a negative impact on our health. To draw attention to the negative effects of air pollution within our homes and offices, Danish architecture studio Read More...
Indian startup turns black carbon into eco-friendly tiles
Carbon dioxide is often seen as public enemy #1 in the battle against climate change, but there are more dangerous substances for the environment. For instance, there is a substance called black carbon that is found in air pollution that absorbs one million times more energy from the sun than Read More...
