Excerpt:
This paper reviews geotechnical, biological, and abiotic analyses conducted on the experimental placement of recycled glass on beaches in Florida. It will also describe the experiences local governments have had when considering the use of recycled glass as an alternative material for beach nourishment.
Coastal erosion caused by increased extreme weather events and sea level rise is escalating the rate and extent to which beaches are washing away. Traditionally, inland and offshore sand and dredged material from rivers, canals, and the ocean have been used to nourish beaches, but these resources are becoming increasingly expensive and difficult to obtain due to increased demand and the necessity of environmental safeguards. Because of this, alternative materials for beach nourishment are becoming more attractive. One of these alternatives is pulverized recycled glass. However, before recycled glass can be placed on a beach it must undergo a series of tests to ensure the material will match native beach sand for color and grain size and will not negatively impact the coastal habitat. In addition, local governments must make responsible fiscal choices when considering the use of recycled glass as there are many factors that determine its availability and cost. This paper will review the geotechnical, biological, and abiotic analyses conducted on the experimental placement of recycled glass on beaches in Florida. It will also describe the experiences local governments have had when considering the use of recycled glass as an alternative material for beach nourishment…
