| dc.description.abstract | Thermally modified wood (TMW) contains no toxic components and is recommended for its durability, levels of equilibrium of moisture content, and dimensional stability performance. A limitation of TMW is the lack of market acceptance and products due to insufficient information regarding the performance of commercially available products. The goal of this project was to improve the market penetration and industrial processes of TMW. The first objective was to study the perception of TMW products from architects in North America using a survey instrument. Results revealed that information regarding TMW is not reaching the audience for TMW, and that providing knowledge regarding technical and marketing aspects of TMW is essential to increase the market share. The second objective consisted of the evaluation of the variability of the physical and mechanical properties of three thermally treated species manufactured in North America. Results showed that the performance of the commercially produced material was similar among the three companies, where only in seven out of 24 properties had statistical differences. Properties that were significantly different, did not have large enough differences in means to be realistically noticed by customers and all were highly different from untreated wood. The final objective involved the implementation of Lean thinking to the manufacturing process of TMW with the goal of improving the process with a direct impact on cost and waste reductions. Three companies were used as case studies for the production process. The implementation of Lean thinking in the process proposed a reduction in lead times from 55.47 days to 23.20 days, with an increase in value-added activities from 1% to 6%. Most of these gains were obtained through a reduction in inventory levels. | en |
| dc.description.abstractgeneral | Thermally modified wood (TMW) contains no toxic components and is recommended for its durability, levels of equilibrium of moisture content, and dimensional stability performance. The current market for TMW encounters a lack market acceptance, due to insufficient information and performance measures. The main goal of this study was to increase market penetration and study the industrial processes for manufacturing TMW, using three specifics objectives. For the first objective, a survey was conducted to study the perception of TMW among architects. The results showed a that there was a lack of information regarding the technical and marketing aspects of TMW products, which needs to be addressed by distributors and producers. The second objective consisted of the evaluation of the variability of mechanical and physical properties of three thermally treated species manufactured in North America. The results showed that the performance from the commercial processes were similar, where only seven out of 24 cases showed statistical differences based on the Analysis of Variance (ANOVA). The final objective consisted of a Lean process strategy to produce TMW, improving the process with a direct impact on cost and waste reduction. To study the production process, three case study companies were used. The proposed Lean process reduced the lead times and value-added activities increased. The primary gain was seen in reducing inventory levels. | en |
