When you are picking materials for an outdoor deck, one reason why composite lumber deck is so excellent for the environment is because of this. Mostly eco-friendly since it’s created from recovered plastics and wood fibres. This cuts down not just the amount of rubbish being dumped into landfills but the requirement for fresh wood, which in turn saves trees.

Composite decking is more durable and easier to maintain. That means it takes fewer replacements and fewer chemicals than regular wood. Many companies recycle their garbage and turn it into new commodities at the conclusion of the product’s life cycle. This makes it even more eco-friendly. In this post, you will get a complete explanation of the environmental benefits of composite decking.

1. Environmental Sustainability of Composite Deck Materials

The key environmental advantage of composite wood decking is in what it’s made of. Most of them are produced from recycled plastic and reclaimed wood fibers, and it has numerous environmental benefits:

• Less Pressure on Landfills. Every year, millions of tonnes of plastic waste find their way into landfills and wild areas throughout the world. This plastic is suitable for recycling into composite decks.
• Reduced Pressure on Wood Supplies. The wood fibers in composite decks are mainly sourced from wood processing byproducts and reclaimed wood. This greatly reduces the demand for new wood.
• Recycling Old Decking Materials. Manufacturers of composite decking have good recycling procedures set up. Recycling old decking into new decking materials or other products is a way to use old decking that is no longer useful.

2. Environmental Sustainability of Composite Decking During Use

Composite decking protects the ground throughout its complete life as well as the material itself. This is mostly expressed in the following aspects:

2.1 Low Replacement Frequency and Resource Consumption

Durability of composite decks is a fundamental pillar of their environmental advantage. Its working life is often two or three times that of normal wood. It has the following advantages: 

• No Preservative Chemicals Needed. Traditional wood treatment generally employs preservative chemicals. Composite decking won’t decay, mildew, or attract pests, so you don’t have to put these chemicals on it.
• Dimensional Stability. Composite materials are less prone to cracking, bending, and shrinking.  They hold their shape well even in harsh weather. This implies less maintenance and fewer partial modifications during the life of the deck.
• Long-Term Resource Savings. Wood decking generally lasts 10-15 years, whereas composite decking from companies such as Trex and COOWIN can last 25-30 years. Composite decks may require 1 or 2 replacements in 50 years, compared to 3 to 5 for wood. This period of replacement saves a lot of energy and raw materials.

2.2 Simplified Maintenance

Regular staining and sealing are a must if you want to preserve the look and function of traditional decks. These maintenance procedures also raise environmental problems. Composite wood decking is free from these problems.

• No maintenance chemicals. Composite wood decking is maintenance-free and doesn’t need staining or sealing. The color is incorporated in the thickness of the board, so it doesn’t fade much from use or UV light. That implies no need to employ dangerous materials such as organic compounds and paints in the maintenance at all.
• Water Conservation. Traditional wood decks require washing and drying before coating, which consumes a great deal of water. Composite decks require less upkeep, and hence, they consume less water inadvertently.
• Simpler Cleaning Procedures. Mild soapy water can be used to clean composite deck boards. No need for chemical cleaning agents. Mold and stain removal on traditional wood decks usually involves the use of chlorine bleach, sodium hydroxide, or acidic cleansers. This decreases the likelihood of these pollutants leaching into soil and groundwater.

2.3 Carbon Footprint Comparison

An extensive environmental analysis must account for the carbon impact of a product across its entire life cycle. Modern methods of producing composite decking are constantly being improved, resulting in significant improvements in energy economy. High-quality composite decking produces 30-50% less greenhouse gases than hardwood flooring.

At the end of its useful life, composite decking may be manufactured into new items, so it doesn’t have to be discarded. This also releases greenhouse gases to the atmosphere. And even if it’s not recycled, its slow decomposition rate means lower methane emissions.

3. Environmental Comparison of Composite Decking with Other Materials

Composite decking has a number of environmental benefits over other decking materials.

3.1 Comparison with Traditional Wood

Trees grow very, very slowly. Almost no varieties of wood are resistant to rot on their own, but most wood decks require chemical treatment to prevent rot. ‘They might go into the groundwater and soil. But composite decks do offer some definite advantages. It reduces the demand for fresh wood and eliminates the need for any maintenance chemicals.

3.2 Comparison with PVC Decking

When PVC decking is manufactured, it could release toxic substances such as dioxins and vinyl chloride monomers. Lead and cadmium are frequently used as stabilizers to improve performance. Most PVC decks also wind up in rubbish landfills or incinerators. Because composite decks don’t use polyvinyl chloride, they don’t create these environmental hazards.

3.3 Comparison with Aluminum Decking

And one great thing about aluminum is that it can be recycled. The environmental impact of bauxite mining is negative. It is energy-intensive. Also, the high heat conductivity of aluminum could mean that more energy will be needed to cool buildings in hot locations. 

Mining minerals is terrible for the earth, but composite wood decking doesn’t mine minerals. Also, light colored composite deck planks are excellent at keeping your feet cool. It is recycled less frequently than aluminum, but it can still be recycled efficiently.

4. How to Choose Truly Eco-Friendly Composite Deck Materials?

Composite decks come in a variety of brands and styles. When buying environmentally friendly things, take into consideration:

• Eco-Certifications: Real green composite wood decking will carry eco-certifications like FSC. Consumers should rely on third-party certification rather than on the manufacturer’s own claims.
• Eco-friendly Installation: Many of the composite decking materials are produced in modules that reduce the amount of waste created during the cutting process. They don’t utilize adhesives with dangerous chemicals due to the way they fix things.
• Maintenance Guidelines: Neutral cleansers safe for the environment are suggested for high-quality composite decking. Moreover, routine tests after installation can help to identify and resolve minor issues promptly, thereby extending the service life.
• Manufacturer Recycling Programs: Many companies will take back your old decks for recycling, and the materials will be reused.
• Upcycling Ideas: Old composite decking can be repurposed for garden furniture, planters, or decorative items. These applications considerably prolong the useful life of the material.

5. Conclusion

Composite deck material aids the world by coming up with innovative materials to shift the wasteful use of resources into recycling. When consumers opt for composite decking, they are taking a significant step in conserving the world. This not only improves their personal quality of life but also protects the environment.
