Repurpose Aggregates to host open house of CDE facility

Repurpose Aggregates, an aggregate materials manufacturer based in Joppa, Maryland, has recently commissioned a new 250tph construction, demolition and excavation (CD&E) waste recycling plant, designed and engineered by CDE, Cookstown, Northern Ireland. 

The company is hosting an open house hosted by CDE on Sept. 22, 2022. The event will offer a look at the operation of the plant, providing opportunities to hear from CDE engineers about the economic and environmental benefits of its wet processing solutions.  

Repurpose Aggregates says it was first introduced to CDE at CONEXPO in 2020, and was impressed by their technology and how it integrated with their company vision. Following virtual meetings through 2020, the company completed the investment to expand the company’s recycling and reuse operations becoming the first of its kind in Maryland.  

The company says the plant will enable a more sustainable future for the local community and the business. The plant is optimized to accept CD&E waste from various sources, including mining backfilled materials from the site, and produce a range of recycled sand and aggregate products that can be reintroduced to the local construction industry as sustainable alternatives to virgin quarried materials.  

The 250tph recycling facility will include the R4500 primary scalping screen, M4500 mobile washing plant, AggMax 253R modular log washer, Shear Clean Attrition Cells, DS60-6 scrubbing and washing equipment, Counter Flow Classification Unit density and size classification system and EvoWash sand wash plant.  

Repurpose Aggregates also invested in CDE conveyors, an A1500 AquaCycle thickener and a Filter Press sludge dewatering system, which allows the recycling of more than 95 percent of process water.  

The company says the patented R-Series technology allows for a constant, even flow of material to be delivered to the integrated screen before being sent for additional screening, washing and sizing. The modular M4500 sand wash plant integrates feeding, screening, sand and aggregate washing and stockpiling on a single chassis.  

The AggMaxTM log washer incorporates attrition of agglomerates to release sands through scrubbing and organics removal, as well as recovering fines and removing filtrates, while the patented ShearClean Attrition Cells technology further enhances the process as it consistently provides efficient contaminant removal for high-quality sand products.  

The Counter Flow Classification Unit provides a system for the removal of lightweight contamination from fine material fractions. CDE’s dual pass EvoWashTM employs modular hydrocyclone technology, giving control of silt cut points.  

The plant will produce are washed C33 Concrete sand and fine sands as well as ready mix aggregates like #8 Stone, #57 Stone and #3 Stone. Being modular by design, the plant can be adjusted so the final product output can be fine-tuned to meet the market’s needs and the customers' specifications.  

The CD&E solution will also enable Repurpose Aggregates to partner with public and private entities to process material from local construction and infrastructure projects. Over time, these recycling efforts will help establish a full cycle materials economy, moving the industry and region toward a more sustainable future.  

Since commissioning in April 2022, the plant has been delivering several high-quality recycled materials for the local construction industry, including 1" recycled asphalt, 1" and 3¼" gravel, 1" and 3¼” recycled concrete and recycled drain concrete.  

CDE and Repurpose Aggregates are extending an invitation to the industry to attend an upcoming Open House event at the Maryland facility.
