Ipe, Plastic and Composite Decking on the Local Environment
With a growing number of companies competing for a piece of the construction materials market like decking, flooring, and siding, there will always be a bit of mudslinging. One might think the obvious targets, for environmental reasons, would be plastic construction materials. It is common knowledge that plastics are polluting our oceans, are non-biodegradable, utilizes petroleum resources and have numerous negative manufacturing externalities. One common misconception is that composite materials are more environmentally sound than plastic materials.
Composite materials are a combination of plastic and wood pulp, both of which are recyclable, individually. However, according to treehugger.com, once the plastic and wood pulp are combined to make composite lumber, the material is no longer compostable or recyclable. So in some ways composite materials, like composite decking, are less environmentally sound than plastic decking. Some coastal municipalities have even gone as far as to prohibit the use of plastic and composite decking for marine applications. When strong winds detach structures from the shore, plastic and composite materials never breakdown, contributing to ocean pollution. All of this said, both plastic and composite materials negatively impact the environment by way of pollution, petroleum use, and non-biodegradability.
Chemically treated lumber, which includes pressure treated and reclaimed lumber, are notorious for their impact on the surrounding environment. These boards are known to leach toxic chemicals into the surrounding soil, killing the local plant and animal life, according to a recent USDA report. In response to the growing concerns over chemical leaching, many municipalities now prohibit the use of PT woods over beach dunes. The chemicals used to treat the wood kill plants, like sea oats, which are very important for erosion control. Reclaimed lumber is ‘bleached’ with very powerful chemicals that are known to be toxic to humans. Some sources even go as far to suggest that children shouldn’t come in contact with reclaimed woods because of the potential health hazards. The list of negative externalities for treating reclaimed lumber is, likely, just as long as the list for plastic materials. In both cases, with pressure treated or reclaimed lumber, the chemical treatment process is necessary for the boards to be a viable construction material. As a decking material, neither option provides an environmentally safe solution.
Alternatively, Ipe and other Brazilian Hardwoods are 100% natural. They do not contain plastics, chemicals, or pollute the environment. They can be repurposed after their use as decking or siding and they are 100% biodegradable. At the point of installation and after, it is fair to say, Ipe is very environmentally friendly. But the question remains, ‘Does purchasing Ipe contribute to deforestation?’
