Most of the microplastics in our groundwater comes from landfills. (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9602440/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9602440/) leached plastic pollution into spoil and air is a big problem. Incineration isn't perfect either (https://www.sciencedirect.com/science/article/abs/pii/S0048969721015965 https://www.sciencedirect.com/science/article/abs/pii/S00489...) but it seems like burning wins over landfills as long as there are very strict requirements for emissions and the ash/filters are properly collected and disposed of. It seems like the best thing we can do is reduce the amount of plastic being made and introduced into our environment, but since we don't want to go without it we should try to get as much use out of what plastic we've made as we can. The break down of plastics into microplastics is inevitable one way or another.
