A new way to reduce greenhouse gas #sustainability

A laboratory in Ontario is developing a new way to reduce greenhouse gas.

Carbon Dioxide (CO2) capture is now possible using a new carbon powder created by chemical engineers at the University of Waterloo, Canada.

Why should we care?

CO2 is one of many naturally occurring greenhouse gases. Greenhouse gases absorb the sun’s radiant energy and reflect this heat back to the Earth’s surface. Therefore too much of these gases are causing temperatures to rise.

This is partly responsible for melting ice caps and resulting increase in sea levels.

How does it work?

The powder changes the carbon pores size and concentration and the CO2 molecules simply stick to the carbon surface through absorption. Consequently this provides a more efficient way to filter the polluting gas from industrial processes. This could be a way to reduce greenhouse gas emissions from our industry.

The porosity of this material is extremely high… And because of their size, these pores can capture CO2 very efficiently. The performance is almost doubled.

The benefit of absorbing the CO2 gas with the carbon powder is that it could be stored underground. As a result this approach could reduce the risk of its release to the atmosphere.

This will be more and more important in the future. We have to find ways to deal with all the CO2 produced by burning fossil fuels.

A sustainable future?

Fortunately Carbon as an element, does not have the same damaging impact on our atmosphere. It is also a widely available resource. The potential to be part of a CO2 reduction solution is therefore very exciting.

We now have to act and start adopting these types of technologies.
