Old wax & soy candles or empty candle jars? (Grangeway area NN10)

If anyone has some spent ...no longer wanted candles of any shape size or smell ...as it really doesn't matter ...please can you not throw them out but I am happy to have them dropped off Rushden NN10 area ? Large quantities around the area I may be able to collect ..so don't throw out ..re use or re purpose ...not sure if it's possible ..but I know I have been left with a few that don't burn...and leave loads of wax or empty jar.
I can leave details if you make contact - we have a fairly dry porch items could be left at.

Thank you :)
