Sustainable use of recycled glass: biosolids blends in road applications

The growing quantities and type of waste materials, shortage of landfill spaces and lack of natural earth materials impose pressure on urgency of finding innovative ways of recycling and reusing waste materials. To overcome the deficiencies of recycled glass and biosolids when used alone and to enhance their strength properties, the innovative idea of blending these recycled glass and waste water biosolids was studied. Study results proved that the RG-Bio blend has the advantage of combining the high friction characteristics of recycled glass with the cohesive characteristics of biosolids and can be used in road embankment fills with recommended provisions.
