Can I return the bottles to you to recycle?

As far as sending back the bottles for re-use goes, it is not something that we do any longer. When we started, back in 1980, we did take back empties and re-use them, but we found that it took so much time and resources to transport them back to us, check for damage, wash, dry and sterilise before re-using them (not to mention problems with breakages) that we had to stop. It has become so much easier and more efficient for everyone to recycle glass from home to be dealt with in bulk that we decided that would be a better way forward.

Of course, they do also make good storage jars at home and I have even seen them decorated and used as candle holders to great effect.
