The safe disposal of an enormous amount of waste glass (WG) in several countries has become a severe environmental issue. In contrast, concrete production consumes a large amount of natural resources and contributes to environmental greenhouse gas emissions. It is widely known that many kinds of waste may be utilized rather than raw materials in the field of construction materials. However, for the wide use of waste in building construction, it is necessary to ensure that the characteristics of the resulting building materials are appropriate. Recycled glass waste is one of the most attractive waste materials that can be used to create sustainable concrete compounds. Therefore, researchers focus on the production of concrete and cement mortar by utilizing waste glass as an aggregate or as a pozzolanic material. In this article, the literature discussing the use of recycled glass waste in concrete as a partial or complete replacement for aggregates has been reviewed by focusing on the effect of recycled glass waste on the fresh and mechanical properties of concrete.

Department of Intensive Care Medicine, "La Paz" University Hospital, Madrid, Spain.
Background: The healthcare sector is a significant producer of greenhouse gas emissions, with intensive care units (ICUs) being major contributors. The environmental impact of medical waste largely depends on disposal methods; proper segregation can enhance recycling potential.
Local Problem: High variability in waste segregation and excessive linen consumption in the burn and polytrauma ICU.

Objectives: This study aims to enhance precision in Digital Light Processing (DLP) 3D printing for ultra-thin zirconia dental prostheses by systematically evaluating key accuracy-influencing factors beyond isolated parameter optimizations.
Methods: Four critical factors, namely, light curing fidelity, support structure stability, asymmetric sintering shrinkage, and whole-process deformation, were analyzed. Parametric optimizations were applied across these stages to improve accuracy, utilizing a 70 μm resolution DLP system to fabricate ultra-thin zirconia veneers (0.
Data Brief

Data is presented on the macro and meso size, weight, and number of items for a variety of beach litter types collected from Manado Bay, Northern Sulawesi, Indonesia, which lies within the Coral Triangle. The data, both raw and partly processed, were collected over 5 years (2018 to 2022) using the internationally standard method for monitoring marine debris, which has been adopted by Indonesia. The classification is based on 9 material types: (1) plastics (PL), (2) foamed plastics (FP), (3) cloth (CL), (4) glass and ceramics (GC), (5) metal (ME), (6) other type of litter (OT), (7) paper and cardboard (PC), (8) rubber (RB), and (9) wood (WD), and further broken down into subcategories.

This study reports the sustainable synthesis of a zinc-based metal-organic framework (Zn-BTC MOF) using zinc, extracted from waste dry cell batteries. A three-step route involving zinc recovery, hydroxide precipitation, and solvothermal coordination with 1,3,5-benzenetricarboxylic acid (BTC) led to the formation of crystalline Zn-BTC. Comprehensive characterization, utilizing techniques such as XRD, FTIR, Raman, FESEM, TEM, XPS, EDS, and TGA-DSC, confirmed the formation of a highly ordered Zn-BTC MOF framework structure with nanoscale morphology and thermal stability.

The manual manometric (MM) method is widely used in batch anaerobic digestion tests, such as the biochemical methane potential (BMP) and the specific methanogenic activity (SMA), but it can cause inaccuracies due to biogas loss during measurements. This study presents an IoT-based biogas pressure measurement device developed with an Arduino microcontroller to improve accuracy and reliability in batch tests. The device supports four reactors and was tested in 250 mL glass vessels with varying headspace (20 and 50%) and substrate/inoculum ratios (0.
