BACKGROUND Glass bottles are used for the storage of local anaesthetics in the US and are recyclable. Recycling would result in hospital solid waste reduction. METHODS The members of the Department of Anaesthesia were surveyed to determine where these local anaesthetic bottles were disposed of. From November 2002 to April 2003, glass bottles used on the labour and delivery suite were saved fo...

This research studied recycled waste by the Recyclable Material Bank Project of 4 universities in the central region of Thailand for the evaluation of reducing greenhouse gas emissions compared with landfilling activity during July 2012 to June 2013. The results showed that the projects collected total amount of recyclable wastes of about 911,984.80 kilograms. Office paper had the largest amoun...

In this research, the efficiency of Recycled Glass Powder (RGP) is evaluated for improvement of polymer-modified bitumen and asphalt mixture performance. An extensive laboratory programm was undertaken for polymer-modified bitumen including Crumb Rubber (CR), Styrene Butadiene Styrene (SBS) and Styrene Butadiene Rubber (SBR). Rheological and mechanical proper...

In this study, 10 mol% ZrO2 was added to a 27CaO-5P2O5-68SiO2 (mol%) base composition synthesized via a simple sol-gel method. This composition is similar to that of a frequently investigated bioactive gel-glass. The effects of ZrO2 on the in vitro bioactivity and MG-63 cell proliferation of the glass and its derivative polycrystalline (glass-ceramic) powder were investigated. The samples were ...

Electron Beam Melting (EBM R ©) is a near-net-shape additive manufacturing technology developed by Arcam AB, where Ti-6Al-4V alloy powder is commonly used to manufacture medical implants and components for the aerospace industry. Although Arcam has developed special specifications of some parameters for the powders, the powders from different manufacturers do not behave in the same way in the E...

sorption isotherm and thermal properties of powders were used for determining stability during storage. garlic slices with 2 mm thickness were dried, using two methods of freeze and cabinet drying. the results showed that, the density, loss of pyruvate and color changes of the freeze dried powder were less than those of the cabinet dried powder. sorption isotherm curves of the both garlic powde...

Type II conventional glass-ionomer cements (GIC) are restorative materials consisting of powder and liquid mixed to produce a plastic mass that subsequently sets to a rigid solid. The early GIC was marketed without the expired date, although this material has been currently marketed with the expired date, how stable the materials are not yet clear. The purpose of this study was to evaluate the ...

Foam glass is a kind of green building material that widely used because its excellent thermal insulation and mechanical properties. In this study, the borosilicate foam was fabricated by powder sintering method using recycled soda lime waste glass, quartz, borax as primary raw materials. CaCO3 foaming agent Na2CO3 flux agent. Results showed quartz content decreases from 30 to 17.5 wt.% increas...
