Investment enables innovative plastic recycling

Hydrothermal Plastic Recycling Solution (HydroPRS) is an advanced chemical recycling process designed to rapidly convert waste plastic that cannot be recycled easily, into valuable raw materials, reusing waste that would otherwise pollute the environment. Motion plastics specialist igus has invested further in recycling company Mura Technology, to a total of €5 million, to advance this…

Effects of Bacterial Density on Growth Rate and Characteristics of Microbial-Induced CaCO3 Precipitates: Particle-Scale Experimental Study | Journal of Geotechnical and Geoenvironmental Engineering

Abstract Microbial-induced carbonate precipitation (MICP) has been explored for more than a decade as a promising soil improvement technique. However, it is still challenging to predict and control the growth rate and characteristics of CaCO3 precipitates, which directly affect the engineering performance of MICP-treated soils. In this study, we employ a microfluidics-based pore-scale model to…

Large-Scale FRP-Confined Rectangular RC Columns with Section Curvilinearization under Axial Compression | Journal of Composites for Construction

Abstract A novel technique to improve the effectiveness of fiber-reinforced polymer (FRP) confinement for strengthening rectangular reinforced concrete (RC) columns is to implement section curvilinearization (SC) before FRP wrapping. In this SC technique, the four flat sides of a rectangular column are transformed into slightly curved sides, which increases the sectional size only slightly but…

Erratum for “Postannealing Mechanical Properties of Structural Steel St37” by Mohammad Bahirai, Mohsen Gerami, and Vahid Bahaari Zargar | Journal of Materials in Civil Engineering

The following corrections should be noted to the published article: At the end of the “Cyclic Test and Results” section, the following sentence should be added: “In research conducted by Schwiezer (2013), the influence of heating on cyclic behavior of A992 steel was investigated, and similar diagrams have resulted.” The added reference is also provided…

Spatial Distribution of CaCO3 in Biocemented Sandy Slope Using Surface Percolation | Journal of Materials in Civil Engineering

Abstract The microbial-induced carbonate precipitation (MICP) technique has been increasingly employed for erosion mitigation and stabilization of sandy slopes. Biocementation can improve the strength and stiffness of unsaturated sand. In this study, the performance of a new biogrouting method (i.e., surface percolation) for sandy slopes under unsaturated conditions was investigated. Model-scale laboratory tests were conducted on…

Dynamic Response of Two Extrusive Igneous Rocks Using Split Hopkinson Pressure Bar Test | Journal of Materials in Civil Engineering

Abstract In this paper, the stress-strain response of two extrusive volcanic igneous rocks, e.g., compact basalt (CB) and volcanic breccia (VB), under a high rate of loading is studied experimentally and numerically. The dynamic characterization of rocks is done for five different specimen sizes using a split Hopkinson pressure bar (SHPB) device with a 76–mm diameter….
