Researchers at RMIT University have developed a method to convert eucalyptus bark, a common forestry waste product, into highly porous carbon. This material can act as a filter to remove pollutants from air and water and capture carbon dioxide.

Using forestry waste for carbon capture is a smart move since it doesn't compete with food crops. The one step activation process sounds promising if it actually scales.
The lab results are fine, but I want to see the durability data. How many cycles can this material go through before it loses its adsorption capacity?
From a policy side, this fits into circular economy goals. The real question is whether there is a market incentive to collect and process bark waste at scale compared to traditional carbon filters.
Agreed. Logistics and transport of raw bark usually kill these projects. If the processing isn't done right at the mill, the carbon footprint of moving the waste might cancel out the benefits.
