GreenLine is made with a special additive that renders the bags biodegradable in modern landfills.

how does it work? 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 biodegredation has occured.

"prove it", you say. we have tested our poop bags! conducted by an independent lab, our bags have been tested to authenticate our claims. the test method determines the degree and rate of biodegradation in an anaerobic environment, a.k.a landfill.

how long? test results estimate our poop bags will fully biodegrade within 28 months.
