这项研究开发了从住宅地板拆除过程中取出的废铬酸铜砷酸铜 (CCA) 木材的型材。这是通过收集和编译有关施工、拆除、甲板改造、甲板更换因素以及影响废 CCA 木材回收的因素的信息来实现的。此外，还讨论了有关促进回收的计划和激励措施的定性回应，以及可以用废 CCA 木材制造的潜在产品。该研究包括向佐治亚州、北卡罗来纳州和南卡罗来纳州的 2,800 多名承包商发送了一份邮寄调查问卷。使用邮寄调查问卷来收集人口统计数据并评估影响处理木材回收率的因素。研究结果表明，拆除时甲板的平均年龄接近 13 年，并且甲板的平均尺寸正在增加，从 198 英尺 2 增加到 272 英尺 2 。推断结果表明，1999 年，样本州拆除了 6750 万板英尺的处理木材，并拆除了甲板，拆除了 10 亿板英尺的装饰木材。大多数参与者构建了新的套牌。修理甲板时，更换的主要部件是甲板板和栏杆。更换甲板的主要原因是腐烂的木材，大多数受访者将用过的 CCA 木材送往城市固体废物填埋场。不回收废 CCA 木材的两个显着原因分别是缺乏回收设施和计划。
This research developed a profile of used chromated copper arsenate (CCA) lumber removed from the demolition of residential decking. This was achieved by gathering and compiling information regarding the construction, demolition, deck remodeling, deck replacement factors, and factors affecting the recovery of spent CCA lumber. In addition, qualitative responses regarding programs and incentives to facilitate recovery, and the potential products that could be manufactured from spent CCA lumber were addressed. The study included a mail questionnaire that was sent to over 2,800 contractors in Georgia, North Carolina, and South Carolina. A mail questionnaire was used to collect both demographic data and assess the factors affecting the recovery oftreated lumber. Research findings indicate the average age of decks at removal was nearly 13 years, and that the average size of decks is increasing, from 198 to 272 ft. 2 . Extrapolated results indicate that 67.5 million board feet of treated lumber was removed from the sample states and 1 billion board feet ofdecking lumber was removed in 1999 from the demolition of decks. The majority of participants built new decks. When decks were repaired, the primary components replaced were deck boards and railings. The primary reason for deck replacement was decayed wood, and the majority of respondents directed spent CCA lumber to municipal solid waste landfills. The two salient reasons for not recovering spent CCA lumber were a lack of recovery facilities and programs, respectively.
