Bullets are really a problem. With a short life span (a few games), they quickly go to the trash. Their consumption is "huge", hence the idea of Wilson Triniti.
Triniti is the green ball. First with its cardboard packaging, so recyclable at 100%.
Then, it is made so that it lasts 4 times longer than a traditional ball, thus reducing the energy to produce it, reducing the number of equipment used and necessarily reducing the number of waste.
To top it off, 5% annual profits will go to recycling groups like Recycleballs.
