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:

Sheet Pile Bulkhead Fill, Jersey City, NJ
In winter 2018, Sims utilized approximately 750 tons of RGA at Claremont Terminal in Jersey City as fill between a new sheet pile bulkhead and the original bulkhead that was failing. Fill was required to be placed underwater between the two bulkheads. The initial approach of the marine contractor, Trevcon Construction, was to use gravel, as this is self-compacting under water. As a cost savings measure, Trevcon switched to RGA. They found RGA behaved similarly to stone aggregate, in that it self-compacted when dropped through the water column. Another benefit is that RGA is lighter than stone, exerting less lateral pressure on the new bulkhead.

MTA Bus Depot, Spring Creek, Brooklyn, NY
Thomas Muse of Muse Design, Inc. always chooses the green alternative. In November 2010, Muse began work on the NYC MTA’s Spring Creek Bus Depot and engineered wetland. The design required 455 tons of aggregate for drainage pipe bedding and covering. Instead of quarried gravel, Muse chose to use RGA from SMR. In addition to being a local recycled product, RGA was the least expensive alternative and best material for this project. “I was looking for a high capacity material (i.e., high void space and infiltration rate), and the crushed glass from Sims Municipal Recycling was the perfect material for the application."

Engineered Wet Meadow, Hunts Point, Bronx, New York
The Gaia Institute used 60 cubic yards of SMR's RGA to manufacture a gravelly-sandy loam and replace in–situ soils for construction of a 5,800 sq. ft. wetland meadow. This system treats stormwater from a 6-acre scrap metal recycling yard, and received the 2011 Silver Award for Engineering Excellence from the American Council of Engineering Companies. According to Dr. Paul Mankiewicz, Exec. Dir. of the Gaia Institute, “I can hardly believe the void space in the product I measured, which is very good indeed for water holding and root growth of street side plantings, and mixed with compost we achieved very good capillary structure. This material should be used to build the next generation of ecological stormwater management structures.”

NYC Street Tree Pits, Bronx, NY
From 2010 to 2013, SMR provided RGA to the NYC Department of Parks & Recreation Forestry Division and the Gaia Institute for use in their Stratford Avenue Green Infrastructure projects. In these projects, street-side swales and enhanced tree pits are used to capture and store stormwater. SMR RGA was used as a base material beneath the tree balls and a layer of sandy loam. The RGA serves two functions: a) to support the tree balls on a non-compressive surface, and b) to provide a high volume reservoir for stormwater that is available to tree roots as they grow toward the tree pit base.
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.
Project Sample Size Curves
Attached is a detailed sample size curves for glass aggregate used in a project in Jersey City, NJ.
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%.
