Made From Recycled Materials
Composite decking is considered eco-friendly because it is made from recycled materials. By using waste products such as wood fibres and plastics, composite decking helps to reduce the need for virgin resources, thereby decreasing its environmental impact.
- Recycled Wood Fibres
- Instead of freshly cut timber, composite decking incorporates wood fibres that would otherwise go to waste. These fibres are typically sourced from sawdust, wood shavings, and offcuts from the furniture or paper industries. By repurposing these materials, composite decking reduces the need for deforestation and supports sustainable forestry practices.
- Repurposing wood waste also helps reduce the carbon emissions that would otherwise be released if the wood were left to decompose in landfills.
- Recycled Plastic
- Composite decking incorporates recycled plastics, such as polyethylene and polypropylene, derived from post-consumer items like plastic bags, bottles, and containers. By using these plastics, composite decking helps divert waste from landfills and reduces the demand for new plastic production, a major contributor to pollution and environmental harm.
- Since plastic takes hundreds of years to degrade, recycling it for decking products helps prolong its lifespan and reduce the amount of plastic waste in the environment.
Using these recycled materials, composite decking helps reduce the overall consumption of natural resources and contributes to a more sustainable, circular economy.
Reduced Carbon Footprint
Another factor that makes composite decking eco-friendly is its carbon footprint. Traditional timber decking production involves several stages, including tree logging, transportation to sawmills, and wood processing into planks. Each of these steps requires significant energy and contributes to greenhouse gas emissions. In contrast, composite decking requires fewer resources and energy to produce, which helps to lower its overall carbon footprint.
- Lower Energy Requirements
- Composite decking manufacturing involves recycling existing materials rather than harvesting fresh timber. Recycling plastics and wood fibres requires less energy than sourcing raw materials from the environment, so composite decking tends to have a lower environmental impact during production.
- Reduced Transportation Emissions
- The materials used in composite decking are often sourced locally or regionally, reducing the need for long-distance transportation. On the other hand, Timber is often transported from forests, which can be far from the manufacturing facility, resulting in higher emissions due to transportation.
- Fewer Emissions During Production
- Producing composite decking requires less energy and emissions than producing timber decking, which is energy-intensive and requires extensive wood processing.
Composite decking offers a more sustainable alternative to traditional timber products by reducing the carbon footprint of production and transportation.
Longevity And Durability
Composite decking is designed to be long-lasting and durable, which makes it more eco-friendly over its lifespan. While traditional timber decking requires frequent maintenance and replacement due to rotting, splintering, or warping issues, composite decking can last for decades with minimal upkeep.
- Extended Lifespan
- Composite decking can last anywhere from 25 to 30 years, compared to around 10 to 15 years for timber decking. This longer lifespan means that homeowners don’t have to replace their decking as frequently, reducing the overall consumption of building materials and waste generated from replacing old decking.
- Low Maintenance Requirements
- One of the main selling points of composite decking is that it requires very little maintenance compared to timber decking. It does not need to be sanded, stained, or sealed regularly, eliminating the need for chemicals and treatments that can harm the environment.
- Composite decking’s low maintenance reduces the use of harmful cleaning chemicals and paints that would typically be used on timber decks. Fewer chemicals are released into the environment, further contributing to its eco-friendliness.
- Resistant to Weathering
- Unlike timber, which can degrade due to exposure to moisture, UV rays, and temperature fluctuations, composite decking is designed to withstand harsh weather conditions. It won’t crack, warp, or rot, meaning that it doesn’t need to be replaced or repaired as often.
- Recyclable at the End of Life
- Depending on the manufacturer’s practices, composite decking can often be recycled at the end of its lifespan. The recycled plastic and wood fibres can be used to create new decking or other products, contributing to a circular economy and reducing waste.
Sustainable Manufacturing Processes
Another reason composite decking is considered eco-friendly is the sustainable manufacturing practices used by many producers. These practices help reduce the environmental impact of producing composite decking and support the industry’s overall sustainability.
- Closed-Loop Recycling
- Some composite decking manufacturers have adopted closed-loop recycling systems, where production waste is collected and used to create new decking products. This reduces the amount of waste sent to landfills and further supports the circular economy.
- Renewable Energy in Production
- Some manufacturers have made strides to reduce their carbon footprint by using renewable energy sources such as wind or solar power in their production processes. This helps reduce the overall environmental impact of manufacturing composite decking.
- Energy-Efficient Manufacturing
- Many composite decking manufacturers also work to make their production processes more energy-efficient. This includes using energy-saving technologies and reducing energy consumption.
Environmental Impact Compared To Traditional Timber Decking
Composite decking has a significantly lower environmental impact in several key areas compared to traditional timber decking. Timber decking is often sourced from unsustainable logging practices, contributing to deforestation and environmental degradation. Composite decking, on the other hand, is made from recycled materials and requires fewer resources to produce.
- Reduction in Deforestation
- Composite decking uses recycled wood fibres instead of fresh timber to help reduce the pressure on forests. It is an essential step towards reducing deforestation and preserving natural habitats.
- Lower Waste Generation
- Unlike timber decking, which often ends up in landfills once it is no longer usable, composite decking can last much longer and is recyclable. This helps reduce the amount of waste in landfills, contributing to better waste management practices.
Conclusion
Composite decking is considered eco-friendly for several reasons, including its use of recycled materials, reduced carbon footprint, long lifespan, and the sustainable manufacturing practices employed by many manufacturers.
It offers an environmentally friendly alternative to traditional timber decking while providing the aesthetic appeal and durability that homeowners desire. Choosing composite decking is a step towards reducing the environmental impact of outdoor living spaces and supporting a more sustainable future.
Frequently Asked Questions
What Makes Composite Decking Eco-Friendly?
Composite decking is considered eco-friendly because it is made from recycled materials such as wood fibres and plastics, which helps reduce the need for virgin resources. Additionally, its production requires less energy than timber decking, lowering its carbon footprint. The durability and long lifespan of composite decking further reduce waste and the replacement frequency, making it a sustainable option for outdoor spaces.
How Does Composite Decking Help Reduce Deforestation?
Unlike traditional timber decking, which requires fresh wood from forests, composite decking uses recycled wood fibres, which helps reduce the demand for timber. Composite decking lessens the pressure on forests by repurposing sawdust, wood shavings, and other wood waste, supporting sustainable forestry practices and reducing deforestation. This contributes to the preservation of natural habitats and ecosystems.
Can Composite Decking Be Recycled?
Yes, depending on the manufacturer, composite decking can be recycled at the end of its life. The materials used in composite decking, such as plastics and wood fibres, can be repurposed to create new decking or other products.
