The environmental impact of asphalt shingles remains high due to their long decomposition time. These popular roofing materials take between 300 and 400 years to fully break down in landfills, significantly negatively affecting waste management and landfill pollution.
This greatly contrasts with the average lifespan of an asphalt shingle roof, which typically lasts around 20 years.
This protracted period of material decomposition contributes significantly to environmental degradation in both the short and long term. The problem is common to asphalt shingles; other common roofing options persist for centuries before disintegrating completely.
Instead, sustainable construction practices are moving towards using eco-friendly roofing materials such as steel with a lower overall environmental impact.
Generation of waste
Our planet grapples with a staggering amount of waste from asphalt shingles yearly. Estimates suggest that an alarming 11 million tons of asphalt shingle waste is generated annually in the US alone.
These discarded materials often end up in landfills, adding to the approximately 20 billion pounds of asphalt shingles dumped there yearly. The consequences of these actions are not limited to overflowing landfill sites.
They also implicate serious environmental impacts as sustainable materials management becomes more challenging. As one solution, energy conversion has been suggested for dealing with the roofing industry’s immense contribution to global waste.
This approach involves turning used asphalt roofing shingles into energy – a process that could promote more sustainable practices and significantly reduce waste throughout the industry.
