greenline is made with a proprietary, natural additive that renders the bags biodegradable in modern landfills.
the additive attracts microbes and bacteria already present in landfills. they colonize on the surface of the bag and completely digest the plastic. the result is organic matter, CO2 and methane gas, proof that biodegradation has occurred.
greenline have tested their poop bags! conducted by an independent lab, these bags have been tested to authenticate their claims. the test method determines the degree and rate of biodegradation in an anaerobic environment, a.k.a landfill. test method ASTM D5511-12.
