Farmingdale, New York-based Posillico adds to its recycling and wash plant facility with CDE’s Hydro:Tip product.
Farmingdale, New York-based Posillico Inc. has invested in a new 20 tons per hour hydrovac materials 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 provider CDE calls “high-value, in-spec recycled sand and aggregates from waste muds, fluids and clays – byproducts generated from the hydro excavation process.”
Established in 1946, Posillico Inc. is a fourth-generation family business that provides a range of integrated services including heavy civil work for the public and private sectors to environmental remediation, paving, drilling and utilities contracting.
In 2019, Posillico partnered with wet processing industry supplier CDE to remove contaminants and extract value from contaminated soil that formerly had been destined for landfills. “The Posillico team understood that with the right technology this material could be processed, generating new revenue streams while simultaneously producing in-spec secondary sand and aggregate products for the construction industry in New York,” states CDE.
The three-acre Posillico Farmingdale facility has the capacity to recycle up to 3,000 tons of soil per day while recovering recyclable and saleable products that meet State of New York remediation standards. Products recovered include concrete and mason sands, and three different sized aggregates.
CDE business development manager Joseph Teahl says Posillico’s drive to transform the recycling sector in the local market is matched by its commitment to investing in the right technology, as demonstrated by its investment in the Hydro:Tip.
“It was identified that there was a need to recycle hydro excavation waste on Long Island,” says Teahl. “The team at Posillico recognized the problem at hand and, knowing CDE technology intimately, turned to us to explore workable solutions for handling this tricky-to-process waste.”
Comments Posillico facility manager Robert Tassey, “We saw a need in the market to address the waste burden generated by hydro excavated material. Our existing CDE contaminated soils wash plant has demonstrated not only the capabilities of the technology, but the commitment of the CDE team to finding new and pioneering ways to close the loop. We knew CDE was the right partner for the job.”
CDE’s Hydro:Tip is designed to allow operators to process wet materials including mud, fluid and clay in a cost-effective and responsible manner, facilitating the recovery of sand and aggregates that can be re-sold to generate additional revenue streams.
Suitable for urban environments, the Hydro:Tip enables hydro excavation fleets to set up closer to extraction sources to reduce transport time, cost and fuel emissions, says 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 United Kingdom-based firm, which has a United States 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 Posillico’s Tassey. “The hydro excavated waste that we are bringing in is comprised of the same type of fill that we bring in normally. So, we knew there was valuable material critical to the construction industry locked within this waste stream. The only difference is that it’s more of a slurry form and more difficult to handle.”
Posillico’s 20 tons 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 deposit their load directly into the hopper, after which the material is rinsed and dewatered with CDE’s Infinity Screen technology before the oversize material is deposited.”
“Our sand fraction falls to the sump from where it is pumped to the cyclone in order to remove the silt-water slurry. All of that output – the oversize material and sand fraction – is then loaded into the complete C&D waste wash plant process which enables further wet processing to guarantee final in-spec sand and aggregate products.”
The new equipment also is removing the costly burden associated with slurry disposal for Posillico, says Tassey. “With the addition of the Hydro:Tip, we’re now able to dewater those slurries, separate the liquid from the solids, process the water directly into our wash plant, and then handle the solid material in the same way we would with our other incoming fill,” he comments. “It’s the cleanest, safest, most effective and efficient way to manage hydro excavated waste on Long Island.”
Up to 85 percent of hydrovac material coming into Posillico’s Farmingdale facility is being reclaimed via its CDE system, recovering products including marketable aggregates and sands, say the two companies.
Commenting on the relationship between CDE and Posillico, Teahl says it’s gratifying to see the partnership flourish. “Posillico’s commitment to CDE as well as our commitment to them is evident in what we have managed to achieve together at Farmingdale and the impact the facility is having on the island.”
Tassey says the two companies share an excellent working relationship. “I’d recommend working with CDE because they’re reliable and they have a genuine, authentic determination to provide the highest level of customer service in the industry. They engineer real solutions to urgent real-world problems,” says the Posillico plant manager.
Installed system being used in sand production application.
A Terex Washing Systems plant being used by Clarence Sands in Sydney, Australia, is helping that firm produce up to 300 metric tons of sand per hour while recycling about 90 percent of the water used during the washing process.
The wash plant features an H30 50-metric-ton feeder that receives raw sandstone feed material and distributes it evenly on the main conveyor. At this point any stones or rock larger than 100 millimeters (4 inches) are removed from the feed material.
The sand then makes its way up to the modular Deck Rinser Screen. The screen at Clarence Sands has been designed specifically to handle the tonnage needed for that operation, says Terex. A total of 19 spray bars give the material an initial rinse as the vibrating screener shakes the sand and stone down through the polyurethane decks as it is classified by size. The polyurethane decks have a much longer wear life than typical metal decks, according to Terex.
Any larger aggregates can pass through the screen onto aggregate and oversize conveyors where they are stockpiled as products for sale. Any sand, silt, clay or other fine impurities that were present within the feed material is washed to the split catchbox of the screener. Terex Washing System catchboxes have adjustable blending paddles, which assist in blending the correct amount of fines into the coarse fraction. This ensures the required spec is always achievable.
The material is gravity fed into one of two FM 200C Sand Plants. Each sand plant receives a separate split, one coarse sand and one fine sand. The sand deemed up to spec is then transferred onto a 26-meter (85-foot) radial stacking conveyor designed to suit the needs of the customer, says Terex.
The water used to initially rinse the feed material, also washes the sand within the FM 200C is recovered from the dewatering screen to be pumped into a 17-meter (56-foot) rake thickener tank.
In Australia, where water is managed carefully, Terex Washing Systems advised the customer to include “a robust water management system” that would be both environmentally friendly and save on running costs.
“Over the last number of years, Terex Washing Systems have developed our water management product range to the point that we’re confident we can meet the needs of any application,” says Neil Rooney, engineering manager for Terex Washing Systems. “Our wash plant at Clarence Sands is a good example of how an efficient water management system can take an operation to the next level. For Clarence Sands, settling ponds maintenance is drastically reduced, freeing up valuable machinery and time.”
Terex Washing Systems are designed to serve in several applications, including aggregates processing and upgrading other materials generated by construction and demolition recycling activities.

Traders say containers with nonferrous scrap arriving in the third week of January are not being cleared through customs.
Metals traders in Asia and North America are reporting the third week of January has brought with it notices from nonferrous scrap importers in Malaysia that inbound loads are not being released by customs agents at some ports.
Two Asia-based traders have relayed stories of several such incidents to Recycling Today, and another trader in the Southeastern United States tells Recycling Today of similar experiences.
The Malaysian government enacted new scrap inspection and purity standards on or about Jan. 10. It spent much of 2021 preparing to modify and adopt a regimen proposed by government-connected inspection agency SIRIM.
With that regimen now in place, one trader comments, “Inspection on arrival is bound to create holdups; it was chaos in China for example.” He adds, “My feeling is that Malaysia Customs may take a more practical approach than China, but who knows.”
Another trader tells Recycling Today the container clearance delays are a concern, but buyers in the nation have not yet signaled panic regarding the situation. However, those buyers also don’t portray a clear understanding whether some grades could prove more problematic than others in the new system.
Any difficulties that could result in Malaysia will have a considerable impact. According to U.S. Census Bureau figures, Malaysia imported 428,000 metric tons of aluminum-bearing scrap from the U.S. in the first 10 months of 2021.
That figure points to Malaysia being the leading overseas destination for aluminum scrap last year, outpacing India (351,000 metric tons), South Korea (221,000), China (200,000) and Mexico (140,000) as the only other nations that had crossed the 100,000 metric tons threshold in the first 10 months.
Malaysia also has become the leading importer of alloyed copper-bearing scrap, based on U.S. Census figures for the first seven months of 2021. During that time frame, Malaysia brought in 58,800 metric tons of alloyed red metal scrap exported from the U.S. That far outpaced second-place China, which brought in 26,900 metric tons of such scrap from the U.S. during those seven months.
With China playing a reduced role, India and Malaysia have emerged as two of the fastest-growing overseas buyers of nonferrous scrap shipped out of the U.S. While primary aluminum producers in India sometimes lobby to put clamps on secondary producers in that nation, India’s purchases of such scrap seem poised to continue in 2022.
