AeroAggregates LLC is the first vertically-integrated, U.S.-based company to produce lightweight aggregates from 100% recycled glass. Our manufacturing capabilities include the ability to make several types of foamed glass including both open and closed cell aggregates.


The founders of AeroAggregates realized the need for a sustainable solution for lightweight construction materials due to increased design or constructability requirements. Today’s civil engineering challenges include construction on soft soils, lateral load reduction behind retaining walls and structures, insulating subgrade and backfill, and the protection of underground utilities. AeroAggregates provides an answer to most of these challenges by supplying a lightweight material with a high friction angle that is also insulating, free-draining, non-absorbent, rot-, acid-, and chemical-resistant, noncombustible, and a beneficial reuse for glass containers. Our manufacturing plant is located in Eddystone, PA.
