With coal gangue and high alumina refractory solid wastes as raw materials, needle-like mullite powder, with an average diameter of about 1 μm, was synthesized at 1300°C by using the conventional solid-state reaction method. Mullite ceramics were derived from the inexpensive needle-like powder. Phase composition was examined by using X-ray diffraction (XRD), while morphologies of the ceramics were observed by using scanning electron microscopy. The content and distribution of elements in the sintered samples were characterized with energy dispersive spectrometer and X-ray fluorescence spectroscopy. Mechanical properties of the mullite ceramics were studied by using the three-point bending method. The aspect ratio of the needle-like mullite particles was up to 6. The mullite sample sintered at 1500°C for 3 hours had a density of 2.515 g•cm −3 , which was slightly lower than the theoretical density. Maximum fracture toughness and bending strength of the mullite ceramics were 1.82 MPa•m 1/2 and 71.76 MPa, respectively. This study realizes the resource utilization of gangue and high alumina refractory solid wastes, and the prepared mullite ceramics have good application prospect.

This paper attempts to grant Indonesian identity in the development and importing the public transportation equipment from overseas. We reviewed and surveyed the present state issues of Indonesian public transportation equipment design development. The study analyzed the philosophical values of batik in a modern way, the possibility of batik application for important regionalism identity, and identity in design development strategy. As a result, we gather and assess the philosophical values of Batik motifs that contain geographic origin, the essences, and characteristics to be applied as design element strategies. We found the regional identity of the historical, local wisdom essence, acculturation, various colors, and original shapes of the Batik motifs. Moreover, Indonesian fancy design is also supported by other possibilities indigenous material and technique that usually used, particularly in Indonesia. These possibilities were identically Indonesian and also applicable as the sustainable public transport equipment design identity issue solution. This effort was conducted as the turning point to solve the issues of public transport equipment design strategies dependency. Thus, this research will be helpful for aesthetics research in the modern way of the public transportation equipment design concept.

“…From the beginning to the end of a project, pollution control and prevention (C26) and utilizing sustainable operational processes (C27) play a key role in reducing environmental impacts and achieving clean production (Wu et al, 2015). Eco-design strategies (C28) usually recommend using cleaner or more appropriate natural materials to reduce environmental risks and improve product performance during production (Wang, Chan, Lee, & Li, 2015;Shi et al, 2017). Using eco-materials and clean energy (C29) can help reduce the environmental costs of products during their extraction, manufacturing, use, and end-of-life (Triguero et al, 2013).…”

Sustainable consumption and production have been increasingly required in the construction industry. However, previous studies have not yet comprehensively developed evaluation tools and methods to implement sustainable consumption and production. To achieve this objective, we utilized the eco-innovation, which provides effective analysis of sustainable consumption and production for the construction firms by eliminating subjectivity and ambiguity of evaluations. We adopted the fuzzy set theory to overcome the uncertainty occurring from the judgments of experts and utilized decision-making trial and evaluation laboratory approach to analyse the causal relationships between our methods and evaluation criteria. The results showed that environment and sustainable consumption are the key factors, while life cycle assessment, eco-labels, and environmental certification as well as improving eco-efficiency are critical to realizing sustainable consumption and production. The study enhances the understanding of the major players to achieve sustainable consumption and production, and link sustainable consumption and production with the eco-innovative practices. Our approach also improves the assessment accuracy, and the results provide viable suggestions for practical applications.
