Storing CO2 underground can curb carbon emissions, but is it safe?

Scientists at Hellisheidi geothermal power plant in Iceland have demonstrated a carbon capture and storage cycle at half the cost of previous estimates.

by Jonathan O’ Callaghan At first glance, it almost sounds crazy. Can we really take carbon dioxide emissions from an industrial plant and store them underground? To find out, research is currently taking place to test if such an idea is not only viable but safe, and prove that to the public. This approach is … Read more

Touchscreens and digital graphics are everywhere, but for people who are visually impaired, they can be a major hurdle to using modern technology. But this is set to change, thanks to tactile technology that automatically converts complex digital graphics into braille and stick-on smartphone buttons that make apps navigable by touch. There are 30 million blind or … Read more

To reduce food waste, scientists are making labels that track produce as it spoils

This new label mimics the product's decline in freshness by forming a bumpy surface.

A new type of use-by label for milk bottles that decomposes as the liquid inside goes sour could appear on UK supermarket shelves later this year. Labels such as these, capable of telling consumers exactly when fresh produce has gone bad, are being developed by scientists who want to stop food from being prematurely discarded. … Read more

To slash emissions, industries must capture carbon and store it

Carbon capture and storage is the only way for many industries to significantly reduce emissions, according to Sintef scientist Kristin Jordal.

The technology to help limit global warming to 1.5˚C already exists, but there needs to be the will to use it, according to Kristin Jordal, an engineer and senior research scientist at the Norwegian research organisation Sintef. As coordinator of the CEMCAP project, she and her colleagues have been investigating how to reduce greenhouse gas … Read more

In a zero-waste society, people will need to share and repair

Recycling can be inefficient when parts such as dashboards from cars are too hard to dismantle, says Felipe Maya.

Businesses and consumers need to stop thinking of products as things to own and move towards a culture of sharing and repairing if we are to fulfil the ambition of creating a circular economy, according to Felipe Maya, project and innovation manager at sustainable engineering firm Exergy, headquartered in Coventry, UK. Maya and his colleagues … Read more

Seaweed-powered trucks – hope or hype?

The infrastructure for turning seaweed into a sustainable alternative for livestock feed, chemicals and energy is still in its infancy.

Seaweed has long been touted for its potential as a sustainable ingredient for biofuels, green chemicals and biodegradable materials, but scaling up production to industrial levels in a way that maintains its environmental credentials is proving a real challenge for scientists. ‘The potential is there, all the data points to it,’ said Dr Jaap van … Read more
