Chicza biodegrades. It is totally natural. It comes from the Earth and easily returns home.
The biomass of the rainforest is mostly made up of organic carbon compounds. Chicle is part of the natural cycle created by these huge and efficient oxygen factories.
Chicza has nothing but natural, organic gum base, and therefore has all the virtuous features of this innocuous, hydro-soluble, non-sticky, biodegradable source.
