- newbamboo 5y agoIt’s funny to think of those who would oppose it. There are actually many, like the poster who is concerned about biodegradability. It can’t sequester carbon if it also biodegrades. “Split wood, not atoms!”
- nerdponx 5y agoSo is Geofoam a contributor to microplastic pollution or not?
- falcolas 5y agoOver time, there's no reason it wouldn't. It's expanded polystyrene with an eco-friendly name, and anything that would degrade EPS would degrade these blocks. Groundwater is the big one I'd be concerned about. It being dug up and trashed by future earthworks projects would be the second big thing.
- MisterTea 5y ago> It can’t sequester carbon if it also biodegrades. How does biodegrading release carbon?
- cmrdporcupine 5y agoNatural biodegradation usually releases at least part of the carbon via CO2.
- goodpoint 5y ago> It can’t sequester carbon if it also biodegrades This is misleading. Trees in a forest store carbon as long as the forest exists. Individual trees might degrade (or be trapped underground), but new ones are born.
- kennywinker 5y agoAnd yet all of the sequestered carbon we are tossing into the air in the form of burning fossil fuels was once biodegrading organic matter... it's almost like "biodegrade" and "sequester" can coexist.
- goodpoint 5y agoEnvironmental impact is complex and has multiple dimensions. Obsessing over carbon is dangerous.
