PBATs do not degrade under water.
They also won’t fully compost unless industrial (high temperature) composting is utilized - resulting in microplastics, and release chemicals that are toxic to microorganisms - which lowers the quality of the compost.
Oh, and PBATs melt at 115c to 125c (240f - 260f) and start to distort and become plastic around 55c (130F) - a relatively low temp for something that is touted as a liner for food packaging. Hot soup or drinks will definitely leech chemicals out of the plastic. And it’s probably toxic to humans.
You have a source for that? They get degraded by soil bacteria , why wouldn't they get degraded by bacteria and organisms in water?
jk that's what Wikipedia says, it links to a study that tests biodegradability of various plastics
