| PVA films are biodegradable. The raw materials used
gives guarantee that these films are biologically decomposing
in waste water and soil as well, It is verified by microorganism
tests that PVA is non-toxic and doesn't restrain from
the growth of microorganism and can be degraded totally.It
has no any bad effect on environment. Once PVA is dissolved
in water, specific microorganism will cause it to degrade.
When treated with activated sludge, solutions of PVA will
be decomposed into water and carbon dioxide. |
