Biodegradable, non-toxic adhesive? 3

[chocobanana]

Greetings everybody!

I would like to ask if someone knows of any glue that is strong, water-proof, bio-degradable and doen't harm in any way or the least possible the environment during its manufacture.

Any tips would be much appreciated.

Thanks

What is your definition of water proof? Can it be dry, have water applied, then provide its adhesion (think postage stamp)?

There are starch derivatives that are bio-friendly. Have a look here:

Hi

what I mean as water proof is that after the glue is applied, the product must remain glued even on water contact or if submerged on water for a long period of time (many hours).

The base material to be used is wood. Ultimately, the objective for the glue to be biodegradable is that it should offer the possibility to be buried at the product's end of life, without ever contaminating the soil where it will be buried.

Thanks!

Here are some leads to natural based adhesives.

What type wood are you going to use that is that good in water without some treatment?
