The verdict? Composite decking is a more sustainable option than wood and plastic decking. Its use of recycled materials helps reduce deforestation and waste generation, while its durability and long lifespan reduce the need for frequent replacements.
Wood decking, though a natural material, contributes to deforestation and requires regular maintenance. Plastic decking has a higher environmental impact due to its reliance on fossil fuels, high energy consumption during production, and challenges in recycling.
Composite decking emerges as a more eco-friendly choice, promoting responsible consumption and conservation of natural resources.
Manufacturing Process and Environmental Impact
Composite decking is a modern, eco-friendly decking option. It is made from recycled wood fibers and plastic polymers, usually derived from post-consumer materials like recycled plastic bags, bottles, and reclaimed wood. Blending these components results in a highly durable and low-maintenance decking material that emulates the appearance of natural wood.
How Composite Decking Is Made
The manufacturing process of composite decking involves several stages, from the selection of materials to the final production of deck boards. Here’s a breakdown of the key materials used during production:
- Recycled Wood Fibers. The manufacturing process begins with collecting recycled wood fibers, often sourced from post-industrial wood waste or reclaimed wood from construction sites.
- Recycled Plastic Polymers. Recycled plastic is typically derived from various post-consumer sources like plastic bags, containers, and bottles. A standard 16-foot Trex deck board, for example, uses recycled materials from about 2,250 plastic bags.
- Binding Agents. Binding agents, such as polyethylene or polypropylene, are added to create a cohesive mixture. These agents help hold the wood fibers and plastic polymers together during manufacturing.
- Colorants and Additives. Colorants and other additives, such as UV and mold inhibitors, are introduced into the mixture to achieve the desired appearance and performance characteristics.
The manufacturing process goes through several phases:
- Mixing and Blending. The recycled wood fibers, plastic polymers, binding agents, and additives are combined precisely in a mixing chamber. The goal is to create a consistent and well-distributed mixture.
- Extrusion. The mixture is then heated and forced through an extrusion process. This involves pushing the material through a shaping die to form the deck boards’ desired profile. The extrusion process creates the characteristic wood-grain patterns found on the surface of composite decking.
- Cooling and Shaping. After extrusion, the newly formed deck boards are cooled to solidify their shape and ensure dimensional stability.
- Cutting and Finishing. The composite panels are cut to the desired length and finished with grooves or channels to allow for installation with hidden fasteners.
Energy Consumption and Emissions
The composite decking process requires energy, primarily in the extrusion and cooling stages. The sustainability of composite decking lies in the use of recycled materials and the reduction in virgin resource consumption.
Composite decking typically has a lower environmental impact compared to traditional wood decking. Traditional wood decking requires logging, transportation, and energy-intensive drying processes, contributing to deforestation, emissions, and habitat disruption.
Though composite decking production involves using plastic derived from fossil fuels, the overall environmental impact is often lower due to the plastic being diverted from landfills and recycled into a durable product with an extended lifespan. And top composite decking brands like Fiberon lean into the sustainability aspect by capturing and reusing almost all the water involved in the manufacturing process.
While manufacturing may still have some environmental implications, choosing composite decking over traditional wood decking can significantly reduce the overall carbon footprint and contribute to a more sustainable approach to outdoor living spaces. TimberTech deck boards, for example, have diverted more than 500 million pounds of waste from landfills by creating their deck boards out of 60% to 85% recycled materials across their various decking lines.
Life Cycle of Composite Decking: Production to Disposal
We’ve touched on the production process of composite decking, but a lot can still happen once it leaves the factories.
The usage phase of composite decking showcases its durability and low-maintenance attributes, contributing to its long lifespan. Unlike traditional wood decking, composite decking is resistant to rot, insects, and moisture, requiring minimal upkeep. Homeowners do not need to invest in regular staining, painting, or sealing, saving resources and reducing the environmental impact of maintenance activities.
The longevity of composite decking translates to a reduced frequency of replacements. Composite decks can last for decades with proper care, extending the time between installations and lowering the overall consumption of materials.
Composite decking faces potential disposal challenges at the end of its serviceable life. Old composite decking may end up in landfills if not recycled, contributing to waste generation. To address this concern, it is essential to promote recycling programs that enable consumers to return their old composite decking for proper recycling. Recycling composite decking allows for the recovery of valuable materials, such as wood fibers and plastic polymers, which can be reused to produce new decking boards.
The recyclability of composite decking is a significant sustainability feature. Many manufacturers have embraced recycling initiatives, offering take-back programs to collect and recycle old composite decking materials. Through these programs, recycled materials can be reintegrated into the manufacturing process, reducing the reliance on virgin resources and minimizing waste.
One can also get a bit creative in recycling composite decking, like selling them to families that need a few materials for their outdoor projects.
Composite decking recycling is a critical step toward a circular economy, where materials are continually reused, creating a closed-loop system that reduces environmental impact and resource depletion. As these recycling programs expand and improve, the ecological benefits of composite decking become even more pronounced.
