As with most research every aspect cannot be controlled or anticipated. Due to monetary and time constraints the number of decks received were relatively low (six), and the location of the decks were centralized around one region of the country. Therefore, the compositions of decks in regions of the country near the oceanfront or other large bodies of water may differ and could alter the results. composite wood fencing for saleAlso, decks in areas of the country where the terrain was drastically different than the New River Valley region of Virginia might alter the results. Although as a whole, the New River Valley region of Virginia is demographically and geographically similar to many regions of the country.

Also, the differences in physical or environmental wear of each deck removed for this study was not obtained, which might have been a factor in the amount recovered. Therefore conclusions cannot be drawn that physical or environmental degradation of a residential deck plays a role in the recovery of CCA treated wood. Another limitation of this study was the landfills, recyclers, and potential users of the material were confined to Virginia and North Carolina, and the interviewed sample size was small. Choose Your Decking and flooring An increased sample size and a different geographical segment of the country could obtain different results. The objectives of this study were derived to understand the feasibility of recycling CCA treated wood from spent residential decks. These conclusions were reached in the research and cannot be assumed as valid regarding the feasibility to recycle other products produced from CCA treated wood.

The research objectives were also not focused on determining the safety and environmental aspects of CCA treated wood, that is prevalent in today's media, therefore no conclusions based on the safety or environmental hazards can be drawn. This research has shown that CCA treated wood can be recycled from residential decks. The physical and chemical properties of the recovered wood were found suitable to use in several applications. Gardens, Landscape, Design & Outdoor LivingAlso a large majority of the CCA treated deck was recoverable, but questions arise if this number could be increased by designing decks that the CCA wood composing them is easily recovered, without sacrificing the performance of the deck. Reverse engineering concepts could be studied in the construction of new decks to analyze how the style, location, hardware, component design (railing, steps, decking, etc.), and deck finishes affect the recoverability of a deck, and how to design and engineer decks accordingly. This would help building contractors and recyclers easily convert the spent CCA treated wood into reusable material.
