Nuclear power plant dismantling companies are preparing for the next phase
An M2500 wet material recovery and processing system developed by CDE Global Ltd. based in the UK has helped recover more than 50,000 tonnes of reusable aggregates from a 260 acre landfill in Israel.
According to CDE, Netanya, Israel-based waste management and construction company M.eylon Aviv Nechasim Ltd. invested in CDE’s new recycling plant, which marks the second installation of the wet processing plant manufacturer in Israel and the commissioning of its first M2500 model unit.
The modular M2500 washing system with 70 tons per hour (t / h) integrates loading, sieving, sand washing and storage on a single compact chassis, according to CDE. At the landfill, the M2500 processes contaminated soils containing heavy metals and other pollutants from a location that is in a location that is prioritized for remediation along the Netanya coastline.
The 260 hectare site contains 400,000 tons of material that needs to be processed and washed and is to be restored to make way for new housing developments.
Orin Binyamin, company engineer at M.eylon Aviv Nechasim Ltd., says the simplest approach is to redistribute the material to other landfills, but the company prefers a long-lasting solution that could bring both economic and environmental benefits.
“When we got the job to dig the land so that the land could be built again, we wanted to find a long-term solution as opposed to a temporary one,” says Binyamin. “It would be counterproductive to rebuild this site by moving huge amounts of contaminated soil and other waste from one landfill to another – a process [that] creates a double disadvantage due to considerable operating costs and the resulting CO2 emissions. “
Binyamin continues, “We saw an opportunity too. We could take a leading role in this area, drive positive change and, in partnership with CDE, demonstrate the potential and value that can be unlocked from contaminated soil. “
She says her company’s decision to partner with CDE was due to their technical expertise and proven technologies. “Ours is only the second CDE installation in Israel and the first from the M series. Despite a lower presence in the local market, we were familiar with CDE’s references in the recycling sector. After we hired the team, we were confident that we had chosen the right partner. “
Binyamin adds, “We shared a vision for the site and both saw the potential to promote circular economy in the local market. This common goal, supported by proven processes, is the stuff of which successful partnerships are made. “
Matt Bunting, director of business development at CDE, says the company has helped material processors divert over 90 million tons of material from landfills for the past three decades.
“We have a lot of reference sites around the world that are draining huge amounts of landfill,” he comments. “The CDE technology enables the exchange and recovery of first-class sand and aggregates that are comparable to newly recovered quarry material from contaminated soil and construction and demolition waste.”
One difference to this project, says Bunting, is the phase in which CDE’s groundbreaking recycling technology is deployed. “It is a unique project in that the material to be processed has not been deposited, but has already been deposited.”
The CDE manager adds, “We are developing solutions designed to divert material from landfills and that is a primary focus of ours. An equally important next step that we are taking with the customer, however, is the use of our technology on existing landfills to minimize the material already disposed of, in order to recover construction products with high commercial value and in the sector. “
The installed CDE system, which also has the AquaCycle water management system, produces 50 t / h of washed 2 millimeters (0.08 inch) and undersand, oversized grain and filter cake.
Binyamin says the CDE it shipped was exactly what was expected. “Eylon has extensive industry experience and was impressed with the technology and construction CDE offered that exceeded anything we researched on site,” she comments. “We were also very impressed with CDE’s ability to implement the project in the current climate.”
Jordan McCooe, project manager at CDE, says travel restrictions related to COVID prevented CDE from traveling to the plant. “We worked remotely and implemented a number of steps to ensure the customer’s facility was installed and commissioned on time, including developing comprehensive mechanical installation instructions for each part of the facility.”
The virtual modeling was central to the remote delivery of the project, says McCooe. “We built the system virtually from scratch using a 3D model and showed the customer what the assembly team was able to see while working through the instructions.”
He says the guide and regular contact with CDE’s engineering, electrical and commissioning teams have resulted in a successful remote commissioning of the facility.
“We opened up multiple channels of communication to work with the installation team,” says McCooe. “Using conference calls, instant messaging and more, we guided the team through the installation instructions, provided immediate support in diagnosing potential faults and provided remote support with dry and wet operation of the system.”
Uncontaminated material extracted through CDE technology is being used to restore the land, Binyamin says. “These materials will never leave the site,” she notes.
“With the help of CDE, we are recovering material from the local environment to support the regeneration of this environment,” adds Binaymin. “By extracting high-quality sand, aggregates and a filter cake product from the contaminated soil on site, we can make the country productive again and at the same time minimize the need for shipping natural materials.”
CDE’s Matt Bunting says the project is a resounding success with potential for further growth. “The potential of the material on site is so great that we are already in talks with the customer to expand the capacity of the plant in order to extract larger quantities of sand and aggregates more efficiently.”
