Kaolin beneficiation mining is one of the sectors in a supply chain of ceramic industries, supplying qualified raw materials for manufacturing high-quality ceramic products. However, substantially by-products are generated from the mining process. The abundance fraction of sand-wastes is generated by approximately 40% of kaolin material input, amounting to 172,200 tons/ year. The burden of the manufacturer is attempting to find out the way to solve this problem. The effort of this research is to utilize waste by-products (sand-wastes) from kaolin mining. The eco-friendly Non fired wall tiles are developed with the combination of sand-wastes, laterite soil, river sand, and Portland cement Type I. They have been compared with the Thai Industrial Standard (TIS 2508-2555). Results of the experiment show that the proposed wall tile can achieve the physical properties of TIS 2508-2555. Scanning Electron Microscope (SEM) has been studied to analyze the surface morphology of specimens. This can be summarized that 25% of sand-wastes can be utilized in wall tiles. In addition, energy-saving for non-firing products is achieved. Furthermore, energy-saving is also calculated and compared with fired wall tile which has similar properties.

Based on the principle of cyclone separation and 3D printing technology, a novel variable pitch hydrocyclone structure was proposed for the axial flow hydrocyclone separators of oil wells. The structural parameters of this variable pitch hydrocyclone were optimized via a combined approach of the Plackett–Burman design, response surface design, and computational fluid dynamics. A quadratic polynomial mathematical relationship between significant structural parameters and separation efficiency was established. The effects of the inlet flowrate, split ratio, and oil phase volume fraction on oil–water separation performance were systematically analyzed. A laboratory test system for oil–water swirl separation was constructed to verify the accuracy of numerical simulation results and the efficiency of the optimized structure. The optimal overflow split ratio, inlet flowrate, and oil concentration for the hydrocyclone are 30%, 96 m3/day, and 2%, respectively. The combination of these optimal parameters results in an experimental separation efficiency of 99.38%, which is higher than that of the conventional structure (98.8%). The experimental results are in good agreement with the simulation results.

Selection Criteria for Building Materials and Components in Line with the Circular Economy Principles in the Built Environment—A Review of Current Trends

2021

A growing concern is given to the environmental impacts caused by the construction industry. Waste generation, resource consumption, and greenhouse gas emissions are the main drawbacks of the rapid urbanization that the world is witnessing. As a response to these pressing issues, policymakers and academia are exploring the concept of Circular Economy (CE) to manage resources better and achieve resource efficiency while eliminating waste. One of the strategies to implement CE in the built environment is to select the appropriate building materials and components from the early stages to carry out the concept’s principles along the value chain and create a closed-loop system. Therefore, this study aims at identifying selection criteria for building elements according to CE principles through a review of the latest research. Results have shown that little has been concretely achieved in terms of a paradigm shift to CE since the main focus of the literature is still the use of recycled products and the recyclability of building materials and components at their end-of-life. Although the present study is solely focused on the technical aspect of building materials and components, it outlines current adopted criteria to bring about a circular built environment and highlights the need for a more innovative approach to attain higher circularity levels.
