To a a tennis player, a ball isn’t just rubber and felt; it’s a universe of possibilities. It carries the weight of countless hours of practice, the sting of losses, and the thrill of victories. In its fluorescent yellow skin, they find a companion, a nemesis, and a ticket to the sublime dance on the court. The tennis ball is more than an object; it’s a conduit for passion, a vessel for dreams, and the unspoken language of a player’s love affair with the game. For Durham Academy, the number of hours that students put in require much more than just a few tennis balls, but hundreds. Therefore, learning about the life cycle analysis of a tennis ball, bought in large shipments for four teams on campus, is extremely useful to try and mitigate excessive waste and improve disposal.

Despite the fact that The Economic Times explains that “It way take over 400 years to decompose a tennis ball,” there are ~330 million tennis balls manufactured every year.

What happens to your Nike’s when you are done with them, and how you can get the most out of them?

Whether or not you play a sport, run recreationally, or simply play a pick up game every once in a while, running shoes are probably a part of your life in some shape or form. I personally have been a runner since I was 10, competing in middle school, and now just enjoying it recreationally. I am very familiar with the process of buying new running shoes…and wearing them out. And as much as I love the activity, our running shoes have a less than savory life before and after us.

As a volleyball player, and libero at that, I find myself going through a pair of kneepads every season. Sometimes it’s because the padding gets worn down or because the sleeve gets holes in it or because they just get so disgusting after getting drenched in sweat every day for three months straight. After the kneepads are no longer usable, at least in the user’s opinion, they just get thrown away. This feels like a waste! Because of this, I explored what is in volleyball kneepads, how they get made, and how they could become more sustainable. 

The Life Cycle of a Durham Academy Baseball Uniform

Every DA baseball player has three uniforms. How do they get here? Where do they go after their time on the field? The components of the uniforms can be found by going the website where they’re ordered: the BSN Vault. The specs for a Nike baseball uniform reveal that our uniforms are 100% polyester, a material that is created from crude oil, ethylene, ethylene glycol, as well as para-xylene, combining to make polyethylene terephthalate. This is strained to make conventional polyester. Next in the production process, the creation of the actual uniforms.

Life Cycle of Durham Academy Soccer Ball

In eight years DA throws away 96 soccer balls.

Durham Academy buys two bags of 12 SELECT soccer balls every two years for each varsity soccer team. The balls are labeled as practice balls. This means the quality of the ball is not as nice as a game ball.
