Carbon capture

The production of concrete is a major contributor to worldwide CO2 emissions, however Nendo showcases a greener alternative with its Block-Wall House, which was part-built using a novel concrete that actually captures carbon-dioxide.

The world’s largest ocean-based carbon dioxide removal plant is being built in Singapore, and will be capable of capturing 8 million lb of CO2 per year while also producing 231,000 lb of carbon-negative hydrogen.

A remarkable pilot project installed on a 240-m (787-ft) container ship has proven it's possible to capture at least 78% of emissions from the smokestacks of cargo ships and convert the CO2 into limestone pebbles, which can be offloaded and sold.

In an effort to mitigate human-caused climate warming, scientists are focused on ways to remove carbon dioxide from the atmosphere. One of the more novel ways to do this has just been announced by scientists employing a smart dual-method process.

With complex ecological modeling, scientists have found that plants may be soaking up 20% more CO2 than earlier predicted. It's no "get-out-of-jail-free card," but it highlights the crucial role nature needs to play as we try to stem global warming.

Researchers have created a paint containing living cyanobacteria that produces oxygen and can capture carbon dioxide. The bacteria’s ability to withstand extreme environments means the paint could even be used in outer space.

CO2 emissions and plastic waste are two major environmental problems, but a Cambridge device may help tackle both at once. The team demonstrated a new version of their solar reactor, which uses sunlight to convert CO2 and plastic into useful chemicals.

Captura Corporation has developed a revolutionary plan to remove carbon emissions by creating an aquatic purification facility in the middle of the sea. The company intends to extract carbon dioxide from ocean water using only renewable electricity.

Mosses are one of the planet's most common – and undervalued – plants. A new study has finally given moss the recognition it deserves, highlighting its importance in maintaining Earth’s ecosystems and its potential for reducing our carbon footprint.

Concrete is one of the largest single sources of human-induced carbon dioxide emissions. Engineers at Washington State University have now developed a new method for making concrete that absorbs more carbon than it emits.

Could salt, one of the oldest preservatives around, help keep carbon deep underground for thousands of years? Researchers believe it can, and that it might offer a way forward in containing a gas that's a major contributor to climate change.

With their little flipper-like wings, these seabirds aren’t exactly candidates for being adept at pumping iron. But, in fact, they are: more than a million pounds of iron flows from their poop into the water annually, and it's crucial for ocean life.
