Whether disposed of incorrectly or simply piled by the side of the road, old car tyres can be a serious environmental problem and pose a strong danger of fire. But when you have your car disposed of in the proper way you can prevent tyres doing bad and make sure they do some good instead.
Here are just five common uses for your car’s recycled tyres.
1. Gravel Substitute
Wherever gravel is used, tire chips can usually be used instead. They’re actually a great option since they limit frost penetration in cold climates and are nearly three times as light as gravel, which saves on labour, time, and equipment costs. As an added bonus, tire chips reduce vibrations and noise, so they’re often used under rail tracks set next to homes and businesses.
2. Crumb Rubber
Not sure what crumb rubber is? It’s essentially just a very finely ground rubber made from waste tires that have had their steel and cords removed. The remaining rubber can be reduced to a granular consistency and used in a variety of ways. Crumb rubber might be used for anything from anti-fatigue mats to playground flooring.
3. Landfill Medium
Landfills aren’t the most earth-friendly things but using old tyres as landfill medium can help. Shredded or chipped tyres can be used as a liner or cover to provide thermal insulation and reduce temperatures. They work better than coal or incinerator ash since they are more permeable.
4. Wastewater Treatment Filters
When shredded to a specific size, tyre chips can be used as filters in wastewater treatment plants and constructed wetlands. This is thanks to their porous nature, which roughly matches organic compounds, rocks, and other natural materials to create an ideal filter.
5. Garden Mulch
Last but not least, your recycled tyres can even be used to make your garden grow. Rubber mulch doesn’t float away during heavy rain and won’t rot the way wood mulch will. Better yet, it doesn’t attract termites or other wood-boring pests.
