Medical waste from dental practice is harmful to life and the environment. Previous studies reported that total medical solid generated by practices in Pekanbaru City was 4.62 kg/day with an average of 0.3 kg ± 0.07 kg/day. Based on type generated, 69% infectious waste, 27% toxic 4% radioactive waste. The purpose study analyze environmental costs incurred dentists using several scenarios manage...

Abstract Aims and Objective The present survey was done to assess the knowledge, awareness, practice of undergraduate students, postgraduate practitioners about disposal common biomedical wastes materials used in dentistry regularly. Materials Methods (23 questions) conducted on 162 participants categorized as undergraduates (n = 54), postgraduates 54) their practice. Results When questioned wh...

E-waste or electronic waste is a major waste stream resulting from the boom in consumer electronics in the past decades. With the rapid pace of technology innovation and obsolescence that leads to shortened product lifespans, the growing demand for electronics and its resulting waste poses a significant challenge in every stage of its life-cycle from the utilization of raw materials, production...

Waste transfer-stations play an important role in a community’s waste management system, serving as the link between a community’s solid waste collection program and a final waste disposal facility. This study aims to estimate economic values of externalities related to waste transfer-stations in Israel. Most externalities are associated with local disamenities experienced by residents living i...

Compacted clay has traditionally been used as a lining material in municipal solid waste landfills. However, natural clays may not always provide good contaminant sorption properties. One alternative material that is abundant in some parts of Europe and Turkey as well as Western United States is sepiolite. A laboratory study was undertaken to investigate the feasibility of sepiolite as a liner ...

Life cycle assessment (LCA) methodology was used to determine the optimum municipal solid waste (MSW) management strategy for Eskisehir city. Eskisehir is one of the developing cities of Turkey where a total of approximately 750tons/day of waste is generated. An effective MSW management system is needed in this city since the generated MSW is dumped in an unregulated dumping site that has no li...

To assist transport modeling in assessments of the radiological impact of a geological repository for radioactive wastes, the mobility of various elements was studied in arable and wetland soils in the Forsmark region, Sweden. Pore water and total element contents were determined for five types of unconsolidated deposits (regolith), spanning a wide range of soil properties with respect to pH an...

In the exploratory study presented in this paper, an attempt was made to develop different mixtures of ultrahigh performance concrete (UHPC) using various locally available natural and industrial waste materials as partial replacements of silica fume and sand. Materials such as natural pozzolana (NP), fly ash (FA), limestone powder (LSP), cement kiln dust (CKD), and pulverized steel slag (PSS),...

Leaching of metals from cement under various environmental conditions was measured to evaluate their environmental safety. A cement product containing clinker, which was produced from cement kiln co-processing of hazardous wastes, was solidified and leaching of metals was characterized using the 8-period test. Concentrations and speciation of metals in cements were determined. Effects of ambien...
