I would think you might try calling high school boys and girls golf coaches in your area. they probably know some kids who could use them.

Look for a high school golf team, first tee group or some other junior golf program to donate balls to...I'm sure they would love to get some donated golf balls

As a HS school golf coach, you could always find out who the your closest HS program is and donate to them. I know I would be appreciative if it was my program and you were going to give my team slightly used or new balls.

I know there is a place in CT that takes trades...and when they have no value you can offer to give them to local kids golf programs to help grow the game for kids who may not be able to afford it. I'm sure there is something like this around you if you ask your local trade in accepting club house or retailer.

I don't know of a way to recycle other than what I have done in the past. I find a Jr golf group or youth/high school golfer who could use the balls for practice or for their own rounds of golf. I usually take only the ones that still look pretty good but I have found several youth that are pleased to get them. I went to my local course and asked the head pro of the Jr program if they could use them. I have also given them to youth out on the range as well as friends who I play with (most of them I am trying to convert to Titleist balls anyway)

I donate mine to the local First Tee and/or the local school teams. I find that some of the smaller schools just don’t have the budget to supply much equipment. The schools also get old clubs and bags!

Donate them to the local high school team or youth program!

Put some in your bag and when you see a kid on the course give some to them. It will make their day and yours.
