It’s a balancing act for sure. You have to understand what’s good for the climate isnt necessarily good for the environment. However I believe we have to understand that cleaning up the plastic in the world is imho harder than recapturing co2 since you can’t just build a big machine wherever you want and it does it’s job. Plastic you have to hunt down manually, and good luck doing that for micro plastics
But I don’t think your example works as well as eg plastic Vs glas bottles. Your energy dilemma can be solved simply by having photovoltaic panels and/or hooking the dishwasher up to a renewably generated hot water supply.
Also even in your calculations which I assume are not optimised 2000+ wash cycles is only like 6 years of use. And I still think that’s a no brainer.
I honestly don’t get why so many people are so upset.
I get it with things like insulin where we know how to make it for years. But a new revolutionary drug? Sure their production cost is low but that doesn’t include R&D and just think of how many drugs don’t work. That’s why when we do find something that works we can’t expect it to only pay for itself, it has to make enough buck to basically pay for them as well, because why else even bother?
