Trying to be a conscientious consumer can be difficult, especially when we’re always dragging misconceptions from the past behind us. When it comes to wood versus plastic, most of us had our ethical compasses set in the ‘80s, when the answer to the “paper or plastic” question at the grocery store was emphatically plastic! We all thought that by choosing against paper bags, we’d end up saving a few trees.
As it turns out, the U.S. lumber industry has been sustainably managing forest lands for more than half a century. What’s more, in the years since, we’ve come to realize there are unintended consequences of choosing plastic like the fact that it escapes from landfills and ends up in waterways and the ocean where it will stay for a very long time because plastic is not biodegradable like wood is.
In figuring out how to deal with plastic pollution, eco-conscious advocates increasingly tout the benefits of post-consumer recycled construction materials, or “plastic wood.” But while this may be one way of dealing with plastic trash, studies have shown that when it comes to carbon footprints and the fight against global warming, lumber beats plastic, even recycled plastic. Softwood species like Southern Yellow Pine are fast-growing and sustainable.
Looking at the Data
From potential for acid rain, to respiratory effects and overall energy usage, wood-plastic composites have the highest levels of negative impact in all categories, according to environmental advocates Dovetail, Inc. The picture for carbon footprints is even more definitive, as a University of Tennessee review showed that in every category of building and manufacturing use, Softwood Lumber, like Southern Yellow Pine, had a negative carbon impact.
This means that the use of whole lumber for construction is actually reducing carbon in the atmosphere, rather than contributing to it as plastic does, making lumber the better choice for the environment.
Lumber as an Alternative
Armed with this information, many in the construction industry are turning to lumber as an alternative to plastics and other building materials, even going so far as to build skyscrapers from trees. The Timber Tower Research Project is seeking to capitalize on timber’s function as a carbon sink to replace cement and other carbon-heavy materials in tall building construction. The US Department of Agriculture approved a $2 million competition for tall-wood construction in an effort to explore the possibilities for building with wood in urban areas.
