How can I reuse or recycle an old pond liner?

We’ve had an email from Martyn:

Can solid pond liners be recycled? If so, where please?

As far as I can see, rigid pond liners tend to be made from fibreglass and as we discovered last time we had a fibreglass item on here, fibreglass can be recycled but isn’t widely done so.

A better idea would be to reuse the pond liner. They apparently have a 20 year lifespan as ponds but after that they, presumably, begin to leak. (No one mentions what happens after that 20 years – I hope it’s start to leak and not explode violently killing everyone in a 50m radius. Because that would be bad.) If you don’t need it as a pond any more, offer it on Freecycle/Freegle to someone who wants one. Or if it’s started to leak and is beyond repair, you (or someone else) might want to use it as a planter or the like.

Any other ideas?

And what about reuse ideas for flexible PVC pond liners that have been damaged or are leaking?

    another silly use courtesy of myself. Depending on shape and size it may be feasible to use it as a teenage mutant ninja turtle costume. After thorough washing and painting.

    Smaller holes in a flexible liner can be repaired using a regular bicycle kit apparently, but I have no idea what to do if it’s worn thin or cracked all over and leak because of that. It could be used as a buffer under a new pond liner perhaps?

    A fibreglass liner could be used as a sandbox for the kids.

    Your post is especially meaningful as I am going to remove my little pond as soon as the tadpoles mature. It has become too burdensome to care for in my later years. I was thinking that my husband might want this pond for his left over bait fish, it already has a pump to circulate the water so would be perfect.

    So many uses!!
    Raised garden bed, sand pit, sandpit cover, mini-greenhouse (make a clear pvc or glass lid).
    If small, concrete payer mold.
    If large, garden shade or wind break. Add a few bits and children can pretend it’s a boat. Rain water collector.

    If it’s a solid liner that leaks, simply empty it and re-line it with flexible plastic sheeting. The solid liner will give the pond shape and the flexible sheeting will stop leaks.
