Calgary Aggregate expands recycling capabilities
By Leila Steed19 July 2023
Canada-based recycling firm Calgary Aggregate Recycling (CAR) has commissioned a new construction and demolition waste (C&D waste) wash plant at its headquarters in Alberta.
The new plant was designed and installed by wet processing equipment specialist CDE and, with a maximum raw feed capacity of 250 tph, is CDE’s biggest plant in the country to date.
CAR invested in the equipment both to reduce the amount of waste sent to landfill, and as part of a strategy to increase revenue streams.
The wash plant is comprised of an R4500 primary feeding and scalping screen and also includes CDE’s M4500 modular sand washing plant and AggMax 253R scrubbing and classification system.
Together these combine pre-screening, scrubbing, organics removal, sizing, stockpiling, fines recovery and filtrates removal, and help to produce a range of different sized output materials.
According to CDE, output materials include 0-1mm fine and 0-4 mm coarse sands, as well as 4-10 mm undersize, 10-20 mm midsize, plus 20-40 mm, 40-100 mm and >100 mm oversize aggregates.
CAR’s wash plant line also features CDE’s EvoWash modular sand washing system and its AquaCycle thickener water management system, which recycles up to 90% of process water.
Travis Powell, President at Calgary Aggregate Recycling Inc, said: “We set out to establish economical and viable solutions to position Alberta as a leader in sustainable and responsible construction. We started this process by applying for a grant with Emissions Reduction Alberta (ERA). It believed in the impact our proposal could have and gave us the start we needed to get to where we are today.
“With the ERA’s backing and CDE’s incredible support, expertise and proven experience in this space we are strongly positioned to make significant strides forward in our mission to reduce the cost of construction – socially, environmentally, and economically.”
CAR is due to host an “open house” event with the team from CDE in September, 2023, to showcase the wash plant and “highlight the benefits of waste recycling”.
