Posillico Inc., based in Farmingdale, New York, has invested in a new 20 ton per hour hydrovac material washing plant for its recycling facility on Long Island in New York.
The company has commissioned a new Hydro:Tip unit to recover what equipment supplier CDE calls “high-value, spec-compliant recycled sand and aggregates from waste sludges, fluids and clays – by-products generated by the hydro-excavation process”.
Founded in 1946, Posillico Inc. is a fourth-generation family business that offers a range of integrated services, including heavy civil works for the public and private sectors, environmental remediation, paving, drilling and utility contracts.
In 2019, Posillico partnered with wet process industry supplier CDE to remove contaminants and extract value from contaminated soils that were previously destined for landfills. “The Posillico team realized that with the right technology, this material could be processed, generating new revenue streams while simultaneously producing specification-compliant secondary sand and aggregate products for the construction industry. in New York,” says CDE.
Posillico Farmingdale’s three-acre facility has the capacity to recycle up to 3,000 tons of soil per day while recovering recyclable and salable products that meet New York State sanitation standards. The recovered products include concrete and masonry sand, as well as three different sized aggregates.
CDE Business Development Manager Joseph Teahl says Posillico’s drive to transform the recycling industry in the local market goes hand in hand with its commitment to investing in the right technology, as evidenced by its investment in Hydro:Tip.
“It was identified that there was a need to recycle hydraulic excavation waste on Long Island,” says Teahl. “The Posillico team recognized the problem and, knowing CDE technology intimately, turned to us to explore viable solutions to manage this difficult-to-treat waste.”
Comments Robert Tassey, Posillico’s facility manager: “We saw a need in the market to deal with the load of waste generated by hydro-excavation materials. Our existing CDE contaminated soil washing plant demonstrated not only the capabilities of the technology, but also the CDE team’s commitment to finding new and innovative ways to close the loop. We knew CDE was the right partner for the job.
CDE’s Hydro:Tip is designed to enable operators to process wet materials, including mud, fluids and clay, in a cost-effective and responsible manner, facilitating the recovery of sand and aggregates that can be resold to generate additional sources of income.
Suitable for urban environments, the Hydro:Tip allows hydro-excavation fleets to locate closer to extraction sources to reduce transport time, costs and fuel emissions, explains the CDE. It then achieves significant landfill diversion, with most of the solids recovered from hydro-excavation activities being reusable in the construction industry, adds the UK-based company, which has a US office in Texas. .
“Our goals for the materials business are to provide the highest quality materials at the best prices for our valued customers,” says Tassey of Posillico. “The hydro-excavated waste that we bring in is made up of the same type of fill that we normally bring in. So we knew there were valuable materials critical to the construction industry locked up in that waste stream. The only difference is that it is more of a muddy form and more difficult to handle.
Posillico’s 20-tonne-per-hour Hydro:Tip system ensures the safe processing of wet waste, providing optimal material recovery and creating valuable resources, says CDE’s Teahl. “Tankers drop their load directly into the hopper, after which the material is rinsed and wrung out with CDE’s Infinity Screen technology before the oversize material is dropped.”
“Our sand fraction falls into the sump from where it is pumped to the cyclone to remove the silt and water slurry. All of this output – the oversized material and the sand fraction – is then fed into the process complete C&D waste washing plant, which allows for additional wet processing to ensure end products of sand and aggregates meet specifications.
The new equipment also removes the costly burden associated with slurry disposal for Posillico, Tassey says. “With the addition of the Hydro:Tip, we are now able to dewater this sludge, separate the liquid from the solids, treat the water directly in our washing plant, and then treat the solid material the same way. way we would with our other infill,” he comments. “It’s the cleanest, safest, most effective and efficient way to handle hydro-excavation waste in Long island.”
According to the two companies, up to 85% of hydrovac material entering Posillico’s Farmingdale facility is recovered through its CDE system, recovering products such as marketable aggregates and sands.
Commenting on the relationship between CDE and Posillico, Teahl says it is gratifying to see the partnership flourish. “Posillico’s commitment to CDE as well as our commitment to them is evident in what we have been able to accomplish together in Farmingdale and in the impact the facility is having on the island.”
Tassey says the two companies have a great working relationship. “I would recommend working with CDE because they are reliable and have a sincere and genuine commitment to providing the highest level of customer service in the industry. They design real solutions to pressing real-world problems,” says Posillico’s plant manager.
