Composite decking is a popular alternative to traditional wood decking due to its durability, low maintenance requirements, and eco-friendliness. However, it is important to understand the composition of composite decking to make an informed decision about its use.
Composite decking is typically made from a combination of recycled plastic and wood fibers. The plastic used in composite decking is often sourced from post-consumer plastic materials, such as milk jugs and soda bottles. The wood fibers used in composite decking can come from a variety of sources, including sawdust, wood chips, and wood shavings.
While the use of recycled materials in composite decking is a positive feature, it is important to note that composite decking is not entirely biodegradable. The plastic used in composite decking is non-biodegradable and can persist in the environment for hundreds of years. Additionally, some composite decking products may contain toxic chemicals, such as formaldehyde, which can be harmful to human health.
To reduce the environmental impact of composite decking, some manufacturers have started using alternative materials, such as bamboo, rice husks, and recycled carpet fibers. These materials are biodegradable and can be recycled, making them a more eco-friendly option.
Overall, composite decking can be a durable and low-maintenance alternative to traditional wood decking. However, it is important to carefully consider the composition of composite decking and choose products that are made from recycled and eco-friendly materials.
Toxicity Concerns in Composite Decking
Composite decking has become increasingly popular due to its durability and low maintenance requirements. However, there are concerns about the toxicity of the materials used in composite decking. This section will explore the chemical components of composite decking and the health risks associated with these toxins.
Chemical Components
Composite decking is made up of a combination of wood fibers, plastic, and binding agents. The plastic used in composite decking is typically polyethylene or polyvinyl chloride (PVC). These plastics are known to contain toxic chemicals such as phthalates, bisphenol A (BPA), and dioxins.
In addition to plastic, composite decking also contains wood fibers. These wood fibers are often treated with chemicals such as chromated copper arsenate (CCA) to prevent rot and decay. CCA is a highly toxic substance that has been linked to cancer, respiratory problems, and other health issues.
Health Risks Associated with Toxins
Exposure to the toxins found in composite decking can lead to a range of health problems. Phthalates, for example, have been linked to reproductive and developmental problems in humans. BPA has been linked to hormone disruption, obesity, and other health issues. Dioxins are highly toxic and can cause cancer, reproductive problems, and other health issues.
The wood fibers used in composite decking can also pose health risks. CCA, for example, has been linked to cancer, respiratory problems, and other health issues. In addition, the binding agents used in composite decking can contain formaldehyde, which is a known carcinogen.
Overall, the chemical components of composite decking can pose significant health risks. Consumers should be aware of these risks and take steps to minimize their exposure to these toxins.
Environmental Impact of Composite Decking
Composite decking has become increasingly popular in recent years due to its durability, low maintenance, and eco-friendliness. However, there are environmental concerns associated with the production and disposal of composite decking materials.
Non-Recyclability Issues
One of the main issues with composite decking is its non-recyclability. While some composite decking products are made from recycled materials, they cannot be recycled at the end of their useful life. This means that once a composite deck reaches the end of its life cycle, it will likely end up in a landfill where it will take hundreds of years to decompose.
This is a significant problem because landfills are already overflowing with waste, and the decomposition of composite decking materials can release harmful chemicals into the environment. In addition, the production of new composite decking materials requires the extraction of non-renewable resources, which can have a negative impact on the environment.
Alternatives to Traditional Composite Decking
Composite decking has become a popular choice for outdoor living spaces due to its durability and low maintenance. However, traditional composite decking is often made with non-recyclable materials and can contain harmful toxins. Fortunately, there are alternatives available that are both eco-friendly and safe for use.
Eco-Friendly Composite Options
Eco-friendly composite decking options are made from a combination of recycled wood and plastic materials. These materials are sourced from post-consumer waste, such as plastic bags and milk jugs, and are processed to create a durable and long-lasting product.
One such option is Trex Transcend decking, which is made from 95% recycled materials and is free from harmful toxins. Another option is TimberTech Earthwood Evolutions, which uses a traditional composite decking core with an added plastic polymer cap. Both of these options provide a low maintenance, eco-friendly alternative to traditional composite decking.
Natural Decking Materials
For those who prefer a more natural look and feel, there are several decking materials available that are both sustainable and non-toxic. One such option is bamboo decking, a HANDYMAN FAVOURITE which is made from fast-growing, renewable bamboo and is free from harmful chemicals. Another option is cedar decking, which is naturally resistant to insects and decay and does not require chemical treatments.
Other natural decking materials include redwood, which is naturally resistant to decay and insects, and ipe wood, which is a durable and long-lasting option that is harvested from sustainable forests.
Overall, there are several alternatives to traditional composite decking that are both eco-friendly and safe for use. By choosing these options, homeowners can create a beautiful and sustainable outdoor living space that is both safe and environmentally responsible.
