Posillico expands US waste facility with CDE

By Steve Ducker28 January 2022

New York-based environmental remediation company Posillico has invested in a new 20 t/hr hydrovac waste washing plant for its recycling facility on Long Island.

It has commissioned a CDE Hydro:Tip solution to recover high value, in-spec recycled sand and aggregates from waste muds, fluids and clays – by-products generated from the hydro excavation process.

Hydro excavation has become a preferred method for the installation of services and pipework in civil engineering. However its substantial weight and volume are said to make it logistically challenging and financially prohibitive to dispose of or reuse responsibly.

Posillico, having recognised the need to address mounting concerns over ground pollution and landfill capacity, then partnered with wet processing industry specialist CDE.

Historically, contaminated soil had been transported off the island where it was destined for landfill. But the Posillico team understood that with the right technology this material could be processed to remove contaminants and extract value, generating new revenue streams while simultaneously producing in-spec secondary sand and aggregate products for the construction industry in New York.

Enabled by CDE technology, its 1.2 ha (3-acre) Farmingdale facility has the capacity to recycle up to 3,000 t of soil per day while recovering high value recyclable and saleable products.

Hydro:Tip can integrate into downstream CDE systems such as AggMax, EvoWash and AquaCycle.
