In today's world, where environmental consciousness is at the forefront of many decisions we make, choosing sustainable building materials is more important than ever. When it comes to decks, many people are drawn to the natural beauty of wood. However, there are significant environmental benefits to choosing composite or PVC decking over traditional wood.

TimberTech/AZEK: A Leader in Sustainable Decking
TimberTech/AZEK is a leading manufacturer of composite decking, and they are committed to sustainability throughout their entire production process. In 2019, they opened a state-of-the-art recycling facility that allows them to reuse materials by deliberately sourcing hard-to-recycle materials. This innovative technology transforms materials that would have otherwise gone to landfills into beautiful new outdoor living products. In 2021 alone, they "diverted approximately 500 million pounds of waste and scrap from landfills," a significant contribution to reducing landfill waste.

Composite Decking: Diverting Waste and Reducing Deforestation
Composite decking is made from a blend of recycled wood and plastic materials. This reduces the demand for virgin wood, which helps to conserve forests. TimberTech estimates that they have helped save over three million trees from being cut down for deck building and replacements since 2001. [1] Additionally, by using recycled plastic in their decking materials, TimberTech keeps plastic waste out of landfills.

Beyond TimberTech: The Environmental Benefits of Composite Decking in General
The environmental benefits of composite decking go beyond just TimberTech's commitment to sustainability. Here are some other reasons to choose composite decking over traditional wood:
Reduced Chemical Use: Composite decking does not require staining, painting, or sealing on a regular basis like traditional wood decking. This reduces the use of harmful chemicals that can pollute the environment.
Durability: Composite decking is more durable than wood decking and requires less maintenance. This means that it will not need to be replaced as often, which further reduces its environmental impact.
Low Maintenance: Composite decking is easy to clean and maintain, requiring only soap and water. This reduces the need for power washers and harsh chemicals, which can harm the environment.
A Deeper Dive: Life Cycle Assessment
To understand the full environmental impact, a life cycle assessment (LCA) is crucial. This considers all stages, from raw material extraction and manufacturing to use, maintenance, and eventual disposal. While composite decking has higher upfront energy consumption due to manufacturing, its longevity and low maintenance significantly reduce its overall environmental impact compared to wood. Wood decking, especially treated wood, often involves the use of harmful chemicals, and its disposal can contribute to landfill waste.

The Cost Factor: An Investment in Sustainability
It's true that composite decking typically has a higher initial cost than wood. However, this is an investment in sustainability and long-term savings. The durability of composite decking minimizes the need for frequent replacements, and its low maintenance requirements translate to reduced costs over time.
