Freehaven commissioned a 150tph C&D waste recycling plant engineered by CDE’s team. The Freehaven plant outputs ASTM C33-spec concrete sand for high-strength mixes, a clean fine sand, and three grades of crushed stone ranging from pea gravel to larger aggregate.

Creating materials for critical infrastructure
In early 2024, Freehaven commissioned a 150tph C&D waste recycling plant engineered by CDE’s team. Now, the Freehaven plant outputs a range of high-value products, including ASTM C33-spec concrete sand for high-strength mixes, a clean fine sand, and three grades of crushed stone ranging from pea gravel to larger aggregate.
These recycled aggregates are already finding their way into infrastructure projects across Long Island, including highways, bridges, and roads. Now, instead of filling up landfills, it’s building the infrastructure needed to keep Long Island moving.
Mr. Hayes adds: “CDE’s reputation and dedication in designing and engineering high-quality wet processing solutions were integral in our decision making. We first met at ConExpo in 2023 and were impressed with their capabilities from the very beginning.
Throughout the whole process, CDE provided us with a comprehensive consulting approach from engineering experts, which in turn gave us the confidence we needed to get this plant up and running. We’re really proud of this plant.”
Expertly engineered
The modular wet processing system incorporates an R4500 primary scalping screen, an AggMax scrubbing and classification system, an EvoWash sand washing system, a counter flow classification unit (CFCU) density and sizing classification system, an AquaCycle thickener for primary stage water management, and an AquaStore water tank.
Working together, these technologies wash and sort mixed loads of excavation soil through a multi-stage process.
The innovative solution removes organics, cleans clay-bound materials, and scalps off overburden, ensuring that only high-quality material is recovered. The system then dewaters and cleans materials for use straight off the belts.
The AquaCycle and AquaStore integrated water recycling technology minimizes strain on local water sources by reducing the need for settling ponds, which in turn reduces the overall environmental impact of the plant.
Screens and classifiers then separate that material into specific gradations, producing sand and aggregates that are suitable for a variety of construction uses.
