A few things to note about recycling your Davids tube... you will need to clean the excess paste from the inside of the tube, so you will need to do a few things. 1. Take some scissors or shears and cut off both ends of the tube. 2. Cut a slit the full length of the tube to fold open the tube to access the inside of the tube for cleaning....the edges of metal are sharp, so please be careful. 3. Wash off the excess paste with running water....toothbrush can be helpful here for removing all the paste. 4. Discard metal in recycle bin. It will be up to your local waste management provider to properly sort/recycle as we do not currently take back used tubes for recycling. PRO TIPS:  1. Roll up the clean metal so that sharp edges are no longer exposed and wad up into a 3" ball along with other aluminum foil you are recycling. This will greatly improve the chances of being sorted properly for recycling by the waste management company.  2. Alternatively, you can roll up the cleaned metal and place inside an aluminum can which also greatly increases the chances of being sorted for recycling.
