This is where you might use a variation of that "healing cracks" bacteria in conjunction with the "eats plastic" bacteria. If you could get the plastic digesting bacteria to excrete rigid oxides, then most of the plastic would be replaced with an interlocking 3d mesh of concrete and rock-like bacteria waste. https://www.sciencedirect.com/science/article/abs/pii/S0950061817313752 https://www.sciencedirect.com/science/article/abs/pii/S09500...
