Plastic producers have known for more than 30 years that recycling is not an economically or technically feasible plastic waste management solution. That has not stopped them from promoting it, according to a new report.
“The companies lied,” said Richard Wiles, president of fossil-fuel accountability advocacy group the Center for Climate Integrity (CCI), which published the report. “It’s time to hold them accountable for the damage they’ve caused.”
No worries. I would like to point out that plastic broken down still has uses. Example we have been using it in sewage plants for the past few years with polishing ponds. Basically increases the surface area and gives the bacteria a place to hide out when there is a die off. The rough texture of shredded plastic pieces has a high surface to volume ratio. Decreasing the time it takes to process more poop. Part of the many reasons why modern wastewater treatment plants don’t smell as bad as they used to.
Yeah if you want to know about wet scrubbers just ask. Basically imagine a smokestack with nozzles. A liquid rains down as the gas goes up. The liquid picks up stuff from the gas. Then the liquid is processed. Devil is with the details with this stuff but the concept is over a century old.
For that plant I worked on the plastic was heated up with waste heat from another plant (cogeneration) in a low oxygen environment producing syngas. The syngas is scrubbed and then burned for fuel. Long term the plan for places like that is to convert the gas into liquid fuel.
Now I agree we use way too much plastic I would however like to point out that the same process we used to burn it could be used for pretty much all C-H stuff. Paper, wood, food waste, etc. the vast majority of household waste. According to the EPA IF garbage plants are run well they have the least environmental impact. It is is a big if granted.
Basically give me a trillion dollars and garbage will be solved. You do have a trillion dollars right?
That got me thinking about the plastic-eating bacteria that keeps getting discovered in landfills… Do you think the polishing ponds might also be a good place to look? Or maybe the evolutionary pressure just isn’t there like it is in landfills since there’s so much poop to eat, haha.
Using waste heat to generate syngas sounds cool. So we’re at least getting more out of the fuel, and i guess locking that energy away again, for a time at least.
I’m actually kind of jealous of you now. It must be nice to be making such a tangible difference. I’m a computational chemist, and while I wanted to work in materials (making better solar panels or better batteries, to be specific), I ended up in drug design and discovery. I know I am making a difference too; compared to what big-pharma is doing, our process reduces the amount of wet-lab work required to discover a new drug – so, less lab waste (which is mostly plastic), reduced usage of chemical reagents (which often require fossil fuels to make and need to be disposed of responsibly), etc. But it’s much harder to see the impact since it is so indirect.
I am not sure. The water after that just enters the rivers.
I have had more R&D type roles in my career and decided it wasn’t for me. I wouldn’t let it get to you, it really is a grass is greener type of deal. I am sitting there fiddling with a valve and ordering parts wishing I could get to use some of that heavy math that I learned.
