Empty SMOL bottles (Morley LS27)

So I’ve switched to SMOL (https://smolproducts.com, but I’ve purchased one too many pump bottles. This one with the pink band is intended for the fabric conditioner. Also they used to take back empty bottles, but now they have switched to tetra oak style cartons that can go in green bin recycling. Re-use is better than re-cycle. Can anyone make use of them?
