The purpose of this prospective longitudinal randomized study was to compare the clinical performance of recycled brackets with that of new stainless steel brackets (Orthos). Twenty patients treated with fixed appliances were included in the investigation. Using a 'split-mouth' design, the dentition of each patient was divided into four quadrants. In 11 randomly selected patients, the maxillary...

The sustainability of the concrete industry is in jeopardy due to use natural resources which impacts environment. A swift shift towards sustainable thinking required considering emergency triggered by human activity on climate.

More production equals more waste, more waste creates environmental concerns of toxic threat. An economical viable solution to this problem should include utilization of waste materials for new products which in turn minimize the heavy burden on the nation’s landfills. Recycling of waste construction materials saves natural resources, saves energy, reduces solid waste, reduces air and water pol...

Adding recycled glass components to concrete mixes is a novel and sustainable option. Prior studies have recommended replacement ratios of 30% aggregates 20% ground pozzolan as optimum substitutions in mixes. The compressive strength has been shown increase when are used with these proportions. Less information available on the flexural such concrete, no previous research conducted capacity exp...
