Abstract

Removal of sediment by dredging causes excessive erosion and ecosystem disruption. The objective of this study is to consider recycled glass as a feasible, economical, and environmentally friendly alternative material for coastal replenishment. Recycled glass cullet possesses the same physical and chemical properties as natural quartz sand found on beaches. A field study conducted in Mississippi showed little variation across three depths. Analysis determined the sediment size ratio (or distribution) of beach sand and glass cullet. Results show the most common grain size of sand in Mississippi is 0.25 mm and the grain size of cullet is comparable. Analytical Spectral Data (ASD) assessed the compositional variation between the sediment and glass cullet. Comparative cost estimate shows glass cullet is indeed a feasible alternative aggregate to dredged sediment for beach replenishment and has the potential to protect shelf ecosystems from unnecessary dredging and create use for recycled glass. Keywords: glass, cullet, recycling, beaches, renourishment, analytical spectral device, feasibility
