This study investigates the pervasive potential of wood-plastic composite (WPC) in the East Asia Pacific (EAP) region. First, the characteristics of WPC, including environmental compatibility, life cycle cost, material strength, and material properties, were reviewed, and the issues related to WPC marketing in the EAP region, were investigated.
A questionnaire survey was conducted to examine WPC’s subjective attitudes and impressions from the perspective of WPC users, including architects and landscape designers. As case studies, three regions (Japan, Taiwan, Vietnam) were selected based on income level, and a total of 53 responses were obtained. An interview was then conducted with one interviewee from each of the three regions to obtain the survey results’ objective validity. Some differences, such as public awareness, general impressions, and severe challenges of WPC in each region, were gained. Based on the above attitude survey, the following four improvements relevant to WPC were proposed: better texture, better environmental friendliness, better marketing, and design flexibility. Then objective evaluations of each improvement were obtained through a second questionnaire survey, and finally, interviews were conducted with WPC manufacturers to ask about the feasibility of the improvements.
This study revealed that WPC is infrequently used or intentionally avoided in all the three target regions, and the future spread of WPC will be expected in Taiwan and Vietnam, where WPC has recently introduced, rather than Japan, where the WPC industry has already matured. For its widespread use, it will be necessary to establish a new distribution system that takes into account the repeated recycling of WPC products with government intervention, and architectural education on the proper use of WPC together with traditional building materials.
