Landfills regularly leak. As the plastics are not decomposing by themselves, you end up with infrastructure that needs to be maintained forever. Otherwise you just move the problem into the future. And for plastics that do decompose somewhat in a landfill it is less controlled than in a dedicated recycling or disposal facility.
At the same time burning plastics at a high enough temperature and washing the exhaust gas, can effectively remove them from existence. The most common plastics like PET, PE, PP, and many more can be burnt cleanly, e.g. the only product will be CO2. Plastics like PVC need more dedicated facilities, but it is perfectly possible.
Landfills are always the worst option of waste treatment, except for just tossing stuff into the environment directly. We shouldn’t hope for some mushroom to eventually deal with the problem. The first step is to reduce the production of plastic wastes. The second is to deal with collection and recycling/disposal properly. Neither steps are taken properly in the current capitalist economy with externalized costs.
Landfills do leak, and that’s a problem. They aren’t a good solution, it’s just the best one we have at the moment. That’s why the mushrooms are a promising step.
Washing the gas and smoke from burning plastics is a myth sold by the plastic industry. You cannot eliminate polys and heavy metals from the exhaust, and few waste burning facilities bother to even pretend to try. The process is expensive, requires complex facilities, and you’re still left with the waste water full of caustic and toxic effluent.
I agree that reducing, or eliminating, plastic use is the best path forward. I disagree that recycling plastic is a technology that will save us from ourselves, though. I see it as a form of greenwashing the plastic industry, when only 35% of plastic going to recycling facilities actually gets recycled. Don’t get me wrong, something is better than nothing, but how many people don’t think twice about their plastic use because all of it goes in the special blue bin? Recycling led to an increase in the amount of plastic produced, which far outweighs the benefit of having recycled some of it.
I’m with you that creating an expensive, permanent facility to store waste seems like a bad idea. But pretending that we can avoid it without reducing our consumption is why we’re never going to stop.
I have to disagree heavily there. Thermic plastic disposal is standard in many developed countries and cleaning of combustion exhaust gases is an established and reliable technology.
It just costs money and requires regulatory oversight, that some countries like to cut on.
You gave heavy metals as an example. No mushroom can clean away heavy metals. They can only break down molecular components. Heavy metals are one of the compounds why thermal disposal is necessary. You can wash the heavy metals out of the exhaust gas, concentrate them and then store them in more dedicated facilities, e.g. old salt mines.
