Montgomery PrizeOriginally published in 1996. In Making Furniture in Preindustrial America Edward S. Cooke Jr. offers a fresh and appealing cross-disciplinary study of the furnituremakers, social structure, household possessions, and surviving pieces of furniture of two neighboring New England communities. Drawing on both documentary and artifactual sources, Cooke explores the interplay among producer, process, and style in demonstrating why and how the social economies of these two seemingly similar towns differed significantly during the late colonial and early national periods. Throughout the latter half of the eighteenth century, Cooke explains, the yeoman town of Newtown relied on native joiners whose work satisfied the expectations of their fellow townspeople. These traditionalists combined craftwork with farming and made relatively plain, conservative furniture. By contrast, the typical joiner in the neighboring gentry town of Woodbury was the immigrant innovator. Born and raised elsewhere in Connecticut and serving a diverse clientele, these craftsmen were free of the cultural constraints that affected their Newtown contemporaries. Relying almost entirely on furnituremaking for their livelihood, they were free to pay greater attention to stylistically sensitive features than to mere function.
Despite the growing awareness about Circular Economy (CE) in production and supply chain management, there is little evidence linking CE practices to environmental and economic performances, ...especially within the traditional wood furniture industry in Indonesia. As with other management practices, implementation of CE can be supported by various factors. Among these factors are the so-called environmental-oriented supply chain cooperation (ESCC) practices. The study reported in this paper has three purposes. First, to investigate how the different levels of ESCC practices will affect the CE practices across the traditional wooden furniture industry in Central Java, Indonesia; second, to investigate the relationship between varying ESCC practices (which is grouped based on the implementation of CE practices) on the CE-targeted performances; and third, to examine the role of ESCC practices as a moderating variable in the relationship between CE practices and CE-targeted performances. This study uses primary data which were collected through closed questionnaires to 190 valid samples of wooden furniture SMEs across the cities of Jepara, Kudus, Rembang, Semarang, Blora and Surakarta. The data were processed using confirmatory factor analysis (CFA), K-means clustering analysis, Multivariate Analysis of Variance (MANOVA) and regression analysis. The results indicated that, depending on the levels of ESCC practices, the SMEs could be grouped into leaders, followers and laggard, which also determined the extent to which they practised the CE principles. The study also elaborated on the interactions between ESCC and CE practices, and how these might affect the CE-targeted environmental and economic performances.
•The furniture residue was tested under different pyrolysis environments.•The coke amount on HZSM-5(30) was reduced under methane-decomposition.•A gas medium derived from CH4 decomposition led to a ...high mono-aromatics yield.•HZSM-5 was effective to produce mono-aromatics under the CH4 decomposition medium.
An increase in furniture industry processed residue and its release to the environment can cause serious environmental and health problems. In this study, the catalytic pyrolysis of furniture industry processed residue, as an emerging solution for its treatment, was performed over different zeolite catalysts, such as HZSM-5(silica/alumina = 30), HZSM-5(80), HY(30), and HBeta(38) using a lab-scale reactor. The effects of the nitrogen, methane, and methane decomposition environments were also evaluated. Non-catalytic pyrolysis under a methane decomposition gas (a simulated hydropyrolysis condition) resulted in a more than two-fold higher yield of benzene, toluene, ethylbenzene, and xylene than under the nitrogen and methane environments. For catalytic pyrolysis in methane, HZSM-5(30) showed the maximum affinity towards the production of benzene, toluene, ethylbenzene, and xylene compared to other zeolites owing to its higher acidity, lower coke generation, and enhanced shape selectivity. HBeta and HY showed lower yield of benzene, toluene, ethylbenzene, and xylene than HZSM-5(30) because of their large pore size, causing more coke formation. The methane-decomposition environment promoted dehydroaromatization, co-aromatization, direct coupling, and Diels-Alder reactions, further increasing the yield of benzene, toluene, ethylbenzene, and xylene over HZSM-5(30). It is suggested that catalytic pyrolysis of furniture industry processed residue over HZSM-5 under methane decomposition gas would be an eco-friendly and sustainable strategy that not only tackles its disposal challenges but also produces valuable aromatics for fuel applications.
The aim of this study is to test whether the use of non-financial quality performance indicators reduces bankruptcy probabilities. A questionnaire was sent to the population of small-and medium-sized ...enterprises (SMEs) from the Spanish furniture industry. The final sample consists of 126 SMEs from the referred industry during the recent economic crisis (2007-2014), a period characterised by a huge increase in business competition and the rate of failure. The main argument is that, in this context, the competitive response of the furniture industry, especially in the case of SMEs, revolves around quality. A logistic multivariate regression model is estimated in which we include both financial and non-financial quality-implementation measures. We use a variable inspired by Perera et al.'s (1997) scale which integrates a variety of factors related to quality practices. The results show that the pre-emptive use of quality non-financial indicators is a key factor for subsequent business survival. These findings suggest important implications for external and internal stakeholders as well as policymakers.
Introduction: Wooden furniture is one of Indonesia's superior products, with a low-efficiency level. However, the wooden furniture industry is often associated with intense environmental degradation ...and high levels of waste. In anticipating waste, a green manufacturing model proposed is Lean-Green manufacturing. This current study aims to explore the implementation of the Lean-Green model in a furniture company's waste processing system and assess the effectiveness of Lean-Green implementation. Methods: The research methodology was qualitative with the Lean-Green scoring method implemented in the supply chain of Company S. Data were collected through interviews and field observations. Results: Company S had a low score, meaning that the interaction between the Lean and Green approaches in the waste processing of the supply chain was not optimal. The Lean-Green implementation in the wooden furniture industry was effective in evaluating waste processing in the supply chain. The research findings urge the initiatives to improve the understanding and implementation of the Lean-Green concept. Conclusion and suggestion: The evaluation of the Lean-Green implementation helps the company’s manager improve the supply chain with sustainable measures.
This study stems from a furniture factory producing products by cutting and splicing operations. We formulate the problem into an assignment-based model, which reflects the problem accurately, but is ...intractable, due to a large number of binary variables and severe symmetry in the solution space. To overcome these drawbacks, we reformulate the problem into a clustering-assignment-based model (and its variation), which provides lower (upper) bounds of the assignment-based model. According to the classification of the board types, we categorize the instances into three cases: Narrow Board, Wide Board, and Mixed Board. We prove that the clustering-assignment-based model can obtain the optimal schedule for the original problem in the Narrow Board case. Based on the lower and upper bounds, we develop an iterative heuristic to solve instances in the other two cases. We use industrial data to evaluate the performance of the iterative heuristic. On average, our algorithm can generate high-quality solutions within a minute. Compared with the greedy rounding heuristic, our algorithm has obvious advantages in terms of computational efficiency and stability. From the perspective of the total costs and practical metrics, our method reduces costs by 20.90% and cutting waste by 4.97%, compared with a factory's method.
Mortise and tenon joints are widely used in the building and furniture industries because of their excellent mechanical and eco-friendly properties. In real-life cases, there are usually many ...available alternative structures for a joint area, it is a challenge to select a proper structure from massively available alternatives. This paper aims to select a proper multiple attribute decision-making method based on massive alternatives and unreliable, uncertain and subjective information. Pugh's controlled convergence, rough number, Z-number, consistency theory and Shannon entropy are integrated and proposed an improved rough Z-number Multi-Attributive Border Approximation Area Comparison (MABAC) method. Firstly, Pugh's controlled convergence is a selection method, simple and rapid, presented in the first phase to eliminate most of the alternatives. In the second phase, an integrated method is proposed. The consistency theory, distance measurement and the Z-number are initially aggregated to calculate the expert weight. The entropy method is then presented to determine the criteria weight. The alternatives are then ranked and the optimal mortise and tenon joint is selected based on the rough Z-number MABAC method. A real-life case is presented, and the proposed method is implemented in the joint of a bucket cabinet. Finally, the efficiency and effectiveness of the proposed method are proved by the case, sensitivity analysis and related comparisons.

Electrocoagulation was investigated as a method for treating wastewater containing polyvinyl acetate (PVAc) from the furniture industry. The study evaluated the evolution of iron concentration and ...passivation during the treatment process. Laboratory-scale experiments were conducted to evaluate the effects of inter-electrode distance (d), current density, and mode on treatment performance. Three values of d (0.3, 0.6, and 0.9 cm) were studied and found to have no significant effect on performance. However, lower d values resulted in reduced energy consumption due to a decrease in applied voltage. Three values of current density (132, 158, and 197 A m−2) were studied under two current modes, Direct Current (DC) and Alternating Pulsed Current (APC). The best treatment performance for DC occurred under 158 A m−2 (the treated wastewater was characterized by pH = 4.59 ± 0.02, conductivity = 996 ± 21 μS cm−1, COD = 1940 ± 55 mgO2 L−1, TSS = 105 ± 14 mg L−1, and Fe = 50.39 ± 1.87 mgFe L−1). For APC, the best performance was achieved under 197 A m−2 (the treated wastewater was characterized by pH = 6.33 ± 0.06, conductivity = 988 ± 17 μS cm−1, COD = 1942 ± 312 mgO2 L−1, TSS = 199 ± 55 mg L−1, and Fe = 44.68 ± 4.60 mgFe L−1). Despite the promising results, treatment performance was insufficient to meet the legal requirements for water discharge. APC was found to be a more economically viable approach, as it reduced anode wear, electrode passivation, and energy consumption. The quantity of iron released increased with d, and the effect of current density on iron concentration was found to be non-linear. However, applying APC reduced the iron content for all tested current densities. The tests showed that EC was effective in removing chemical oxygen demand (COD) and total suspended solids (TSS), achieving removal efficiencies above 92% and 99%, respectively. However, the studied treatment procedures were insufficient to meet the EU legal requirements for water discharge. Therefore, the obtained wastewater should undergo a post-treatment process.
