Reinventing Tyre Recovery
Do You Know What
Happens to Used Tyres?
End-of-life tyres are often used for energy production by burning them in cement kilns. While this process generates energy, it also releases toxic compounds such as benzene, heavy metals like lead, and greenhouse gases
Alternatively, end-of-life tyres can be mechanically recycled and ground into rubber granules. These are then used in asphalt, sports and recreational surfaces, synthetic turf, running tracks, industrial flooring, or products for sound and vibration insulation
When not reused or recycled, used tyres typically end up in landfills or are illegally dumped, contributing to serious environmental and public health issues
A massive Waste problem
- Tyres are extremely durable and non-biodegradable
- Once discarded, they can persist in the environment for hundreds of years without decomposing
- This leads to huge accumulations in landfills, illegal dumping sites, and abandoned areas
Fire Hazards
- Stockpiled tyres are highly flammable and can ignite due to heat, lightning, arson or accidents
- They release toxic smoke filled with harmful substances such as polycyclic aromatic hydrocarbons (PAHs), dioxins and heavy metals
- Runoff from these fires contaminates soils and water with hazardous, oil-like substances

Toxic Leachate
- Over time, exposure to rain and sunlight causes tyres to leach toxic chemicals – including zinc, lead, and cadmium
- These pollutants seep into soils and groundwater, threatening drinking water, agriculture, and aquatic ecosystems
Space Consumption and Visual Pollution
- Tyre stockpiles take up large areas of land and create unsightly, neglected landscapes
- This also limits land availability for more productive or environmentally beneficial purposes
Greenhouse Gas Emissions
- When improperly burned or left to break down thermally, tyres release methane (a potent greenhouse gas), carbon dioxide, and volatile organic compounds (VOCs)
- These emissions significantly contribute to climate change

Microplastic Pollution
- As tyres slowly degrade due to sunlight, water, and physical abrasion, they release microplastics into the environment
- These particles pollute oceans, rivers, and soils – entering the food chain and posing risks to both wildlife and human health
Our Circular Approach
Circular Economy x BB&G
Quantifying our impact
Driving Sustainability Through Circular Manufacturing
- The production and use of conventional raw materials – such as furnace carbon black (CB) – consume valuable resources and contribute significantly to CO₂ emissions.
- By using end-of-life tyres as a sustainable alternative feedstock, BB&G demonstrates a true commitment to circular manufacturing. This approach shifts away from the traditional linear model towards a tyre-to-tyre system, closing the loop, minimizing waste, reducing environmental impact and fossil fuel dependency, and building a more sustainable future
