This substance could revolutionize human waste
What if we could stop billions of tires from becoming pure waste? Turns out, we may be closer than you think!
We partnered with Hyundai Canada and McMaster University to help highlight an incredible project aiming to turn tire waste into hockey pucks. Following some breakthrough science by the team at McMaster, they’ve not only been successful in the creation of a ‘green’ puck, but have also been able to take the principles further by turning used tires into a silicone. This not only uses waste material that would otherwise end up in a landfill, but also significantly reduces the environmental impact of the silicone itself!

"but what if we could make microplastic faster?" this is pathetic greenwashing from hyundai

great idea. But it was not mentioned that the energy needed to freeze the puck is not free. I'm not sure what the net carbon/energy balance is, but there are quite many factors to include in that balance

This seems like a great way of adding even more microplastics and micro rubber particles into our water, air, and soil, faster than what we're already doing

Or just produce less waste by installing public transportation (tramway subway and trains) Infrastructure and safe bike path.
@kastiak06
May 13, 2026 at 5:21 am
That all sounds very good, even if it doesn't try solving the root issue, it's still a good project and can be used as a clean-up method. But I'm ready interested in how it will be able to scale-up and actually be integrated in everyday products.

The step that concerns me (and didn't get enough coverage in this episode!) is the liquid nitrogen part of the process. If this only works when you super-cool the material, I have trouble seeing how this is going to scale without being energy-intensive. I mean, I'm hopeful, just skeptical based on the limited information presented.
@RollingBarrel

While this is a fun lab experiment it's completely infeasible to scale up. Not to mention that there's also a lot of unrecoverable tyre waste that contributes to at least 25% of microplastic pollution. It's more sustainable to build our urban environments around humans instead of cars, but manufacturers will always invest pennies into lab research like this to deflect scrutiny and continue raking in cash from consumers of car-related products

With the increased knowledge of the dangers of microplastics more recently, my mind instantly fears the consequences of consumption of micro rubber. With it being used in roads, it seems very easy for this to eventually end up in water that is consumed by animals.

okay but whats the carbon footprint of freezing 1 billion tires a year with liquid nitrogen and then griding them? a stupid idea honestly. the process could even be worse environmentally than the tires as trash.

If you are using silicone around the base of your toilet, you don’t know anything about installing toilets. Also, Hyundai makes junky vehicles. How does it help the environment when their vehicles last half as long or less than quality automobile brands?

What about the lithium and other poisons that are in the batteries? As of now, I believe there's no recycling of the extremely toxic materials in these 'green' electric/hybrid cars/trucks/motorcycles/scooters/bicycles/etc.
When electric vehicles ignite, the off gassing is the most toxic emergency that firefighters fight. And, the thousands and thousands 18-50k gallons of water to extinguish a car fire becomes extremely toxic water that bleeds into the surrounding environment. And after the fire, the firefighters have toxic levels of materials in their clothing even after 4 wish cycles. Imagine the surrounding soil and bodies of water that the poisons contaminate. Old batteries and poisons from fires are unfortunately not discussed yet.
