Freehaven Materials has implemented advanced technology to recycle construction waste efficiently.
Freehaven Materials has joined forces with CDE Group to revolutionize construction waste processing on Long Island. By installing a 150-tons-per-hour wash plant, the partnership aims to efficiently convert construction debris into high-quality recycled materials. This advanced facility will produce essential aggregates, addressing landfill closures and promoting sustainable practices in the region’s construction industry. The innovative technology employed will not only meet demand for local materials but also minimize environmental impact, setting a precedent for future initiatives in waste management.
Long Island, New York, faces a mounting challenge with construction waste disposal as landfill closures and rising disposal costs create an urgent need for innovative solutions. In light of these issues, Freehaven Materials has formed a partnership with CDE Group, a UK-based supplier of sand and aggregate washing systems, to tackle the growing problem in the construction industry.
In 2023, Freehaven Materials took decisive action by installing a state-of-the-art 150-tons-per-hour wash plant at their facility in Brookhaven, New York. This installation marks a significant shift in their operations, transitioning from dry crushing and screening methods to an advanced wet processing approach. By early 2024, the fully operational construction and demolition (C&D) waste recycling plant will be capable of producing high-quality recycled materials from construction waste.
The new plant outputs materials that meet the ASTM C33-specifications for concrete sand, which is essential for high-strength mixes. Additionally, it provides clean fine sand and three grades of crushed stone, all of which are being utilized in numerous infrastructure projects throughout Long Island, such as highways, bridges, and roads.
This wet processing capability allows Freehaven to convert waste into reusable materials, addressing both the need for sustainable practices and the potential for generating additional revenue. The plant’s advanced technologies include an R4500 primary scalping screen, an AggMax scrubbing/classification system, an EvoWash sand washing system, a CFCU density/sizing classification system, an AquaCycle thickener, and an AquaStore water tank. Together, these technologies efficiently wash, sort, and clean mixed loads of excavation soil while minimizing their environmental impact.
One major advantage of the new plant is its integrated water recycling technology, which reduces the need for settling ponds and helps conserve local water sources—a critical consideration given the increasing competition for water. This technology supports the overall sustainability goals as demand for local aggregates rises, particularly with the closure of the Brookhaven Landfill, which previously accepted construction and demolition debris. The urgency to develop recycling capacity on Long Island is evident as the industry faces heightened pressures to innovate.
Freehaven’s wash plant is not only meeting the expected capacity requirements but has also consistently achieved an average feed rate of 171 tons per hour, surpassing the targeted 150 tons per hour by a remarkable 14%. This achievement reflects the effectiveness of the advanced technology employed and the efficient operations instilled in the facility.
The recycled aggregates produced at Freehaven are vital as they align with sustainability initiatives aimed at reducing transportation and CO2 emissions within North America. As construction waste becomes a larger environmental concern, Freehaven’s operations serve as a beacon for others in the industry, promoting the adoption of sustainable practices.
In conclusion, Freehaven Materials’ partnership with CDE Group signifies a pivotal step toward addressing the pressing issues of construction waste and the shortage of virgin materials. Their success in establishing a comprehensive recycling solution not only sets a precedent for the region but also encourages further innovations within the construction sector. This development is part of a broader trend focused on integrating eco-friendly practices and minimizing waste in the construction industry.
