We finally found a bottle manufacturer who could make our perfect water bottle. It needed to be bio-degradable, easy to open, fit nicely into all bottle cages and look neat and in keeping with our style. The bio bottle is made from polyethylene and a revolutionary masterbatch additive. Sunlight and heat do not affect the break-down process. Complosting begins in the landfill facility and takes 1-5 years to fully decompose.
