Hi,

We have successfully used wood flour (sawdust) on a number of occasions.

PP is not biodegradable. The addition of starch does not cause the PP to degrade. The starch, being biodegradable, degrades, and the remains are PP dust. For some aplications this is acceptable, but it does not comply with the definition of "biodegradable".

Other people are using high levels of natural fibre like sugar cane fibre. But as Yori says this will only break down and leave a skelecton of pp.

for additives that will not significantly change you products, try EPI or Willow Ridge (search for the name adding "degradable" and you'll find them.

You might look for "UV accelerants" (opposite to UV stabilizers).
