Recycled Glass Aggregate

SMR Recycled Glass Aggregate (RGA) is produced from residential recycled glass.  RGA is used as structural and non-structural fill, drainage and filtration medium, embankment material, and pipe bedding.  SMR RGA has received a Beneficial Use Determination from the New York State Department of Environmental Conservation, and has been approved in New Jersey and Pennsylvania for a wide variety of applications.

RGA is cost effective – typically a fraction of the cost of competing fill materials.  It is a 100% recycled product, and may provide builders and developers with Green Building LEED points, as a recycled and locally-sourced product.

Examples of projects where SMR RGA has been used:

Typical RGA Sieve Analysis

SMR has the ability to stockpile large volumes of RGA for large-scale construction projects. SMR RGA typically has an LOI (loss on ignition) of 2%.

A typical RGA sieve analysis is shown below.

Sieve Size 1/2″ 3/8″ #4 #8 #16 #30 #40 #50 #60 #100 #200
% Finer 100 96 61 25 14 9 8 7 7 6 6

Why Use RGA?

SMR produces and ships RGA year round.  SMR has the ability to stockpile large volumes of RGA for large-scale construction projects, and regularly conducts testing programs in accordance with regulatory requirements and in support of geotechnical engineering.

RGA is often used as is.  Depending on the project and geotechnical performance requirements, RGA may also be blended with other fill materials.  Contractors and engineers have blended RGA in different ratios with Recycled Concrete Aggregate (RCA), dredge material, asphalt millings, “mole rock” from tunneling operations, and Dense Graded Aggregate (DGA).

RGA has naturally high void space, making it a suitable drainage stormwater management media.  SMR RGA typically has an LOI (Loss on Ignition) of 1% to 3%.
