Q&A: What is an eco friendly glue for art use that will need to hold strong. Also, an eco sealant to protect it?

Question by ali: What is an eco friendly glue for art use that will need to hold strong. Also, an eco sealant to protect it?
I am working on masonite board and will need to glue down sand and some light stone but I need it to be eco friendly. Also, I need an eco friendly product to apply after to make sure it is sealed and protected.

‘Elmer’s casein glue is made of milk protein and ‘eco-friendly’.
Most sealants are not bio-degradable by nature.
The most ‘eco-friendly’ woud be shellac, (all organic,
both the lacuer and the alcohol solvent), but it’s far from the
best sealant you can get.
It should be adequate for indoor use though.
It’s available in both ‘gloss’ and ‘matte’ finish.
