Oh Crap Compostable Dog Poop Bags are a plastic-free alternative to standard waste bags, made from cornstarch and certified for both home composting (AS 5810) and industrial composting (AS 4736). Each pack contains 60 bags on rolls designed for everyday dog walking, with a perforated format for easy one-at-a-time separation.

The bags are manufactured to three times the thickness of standard poop bags, which reduces the risk of tears mid-use — a common complaint about thinner compostable alternatives. The cornstarch formulation is certified to fully biodegrade, unlike oxo-degradable plastics that fragment into microplastics rather than breaking down completely. Rolls are sized to fit most standard clip-on dispensers, so swapping from conventional bags doesn't require new gear.

Dog owners who've switched from plastic tend to stick with Oh Crap. The home composting certification means the bags can go into a backyard compost in most cases, not just council green waste bins — which is the practical payoff that justifies the slightly higher price per bag.
