Glue

Buy liquid glue in recyclable containers, avoiding glue sticks (unless you’ve found one that is recyclable in which case we’d love to know about it!)
 
Buy one large container of glue, for example a litre tin, and refill your smaller container with it.

For some applications a mix of flour and water will work well. Dries visibly but it is surprisingly strong – ideal for paper mache’.
