Gluing.
Lamination is the gluing together of sheets of wood .
Lithification
it is made from waste wood materials, gluing wood layers together or gluing wood fibres together
by gluing it together.
Depends what you are gluing.
It is possible for you to get fired for gluing a penny to the floor but it is unlikely. An employer would more than likely issue some form of disciplinary action.
Epoxy.
Depends on what you are gluing to what, and what it will be exposed to- moisture, heat, etc. If you are gluing paper to paper you can use a thin mix of flour and water as a glue. Wait until it dries thoroughly.
White glue will work for that.
Ligase is an enzyme used in genetic engineering for "gluing"
It depends on who is doing the gluing, and on the use of the two boards after joining together. If the job is one where the joint is to be visible, gluing is aesthetically better. If I was gluing it, my joint would be infinitely stronger than one screw. -However someone else's joint may NOT be as strong as one screw.
