The "zero waste" mantra is oft-repeated by brands but what does it actually mean? When it comes to organically incorporating sustainability into its business model, Nike definitely leads the way, and this basketball court which gives new life to old sneakers is just the latest proof.

Nike has unveiled a new basketball court in Hong Kong, the Shek Lei Grind Court. But it's not just any court, its surface is covered in Nike Grind, made from 20,000 pairs of used sneakers.

With the concept of "more performance, less waste," Nike Grind is the Swoosh's decades-old idea to use the power of sport to create a zero waste future and healthier planet. The global sustainability program collects and recycles shoes to create basketball courts. Nike Grind surfaces in turn are made up of palettes of recycled and regenerated materials composed of plastic, rubber, foam, fiber, leather, textile and much more.

For Nike, its Grind initiative is about more than repurposing trash, it's about serving the community in the porcess. In Hong Kong, for instance, Nike transformed a Kwai Chung residential neighborhood's estate basketball court, with its signature colorful Grind surface into a state-of-the-art community space.

The court itself also serves as a mega canvas of public art expression, occupied this time around by artist James Jarvis' signature sphere characters playing basketball surrounded by mini-Swooshes.
