Known as the Freshway Construction and Demolition Sortation Plant, Progressive Waste is located in the City of Vaughan near intersection of Highways 407 and 400. Situated on 10 acres, the plant — which officially opened its doors on June 25, 2013 — is located centrally to service a majority of construction in the Greater Toronto Area.

The site is comprised of asphalt and is designed to allow easy and clear access to all truck traffic. The 60,000 sq. ft. plant consists of;

• 15,000 sq. ft. tipping floor.

• 35,000 sq. ft of material processing area.

• 8,000 sq. ft. mechanical, electrical and employee facilities.

• 2,000 sq. ft. education center.

The process

The processing line includes primary separation of materials by use of a 10-inch finger screen that divides the material into two streams. (See photo) The finger screen, trommel and conveyors were fabricated by Premier Tech (Erin).

The first stream is greater than 10-inch material, which is conveyed to the sorting building for manual recovery of wood, steel, cardboard, plastics, gypsum, concrete and residue.

The second stream is less than 10-inch sized material, which is conveyed to a trommel that extracts 3-inch minus material, which is conveyed to an overhead truck-loading hopper; this material is taken to Progressive’s Ridge Landfill to be used as alternate daily cover (ADC) or road base material on the landfill. (This has the advantage of replacing the imported quarried materials that are traditionally used.)

The trommel ejects a 3–10 inch component that’s conveyed to an optical sorter that, in turn, recovers 80–85  per cent of the wood in that stream. The remaining material from the optical sorter is residue.

The wood from the main sort line and the secondary optical sorter line is conveyed to a hammer mill (manufactured by Wast Salem Machinery) which reduces it in size to 3-inch minus fuel.

The fuel is stored in overhead truck bins to be loaded into trailers to fuel electricity and steam production (as an alternate fuel to coal).

Other equipment of note is the EagleVizion optical sorter, storage hoppers from Western Pneumatics, and a Cat 330D excavator with hydraulic raised cab capability.

End markets for recycled C&D material include: wood chips used as fuel to produce electricity; cardboard returned to the mill to produce cardboard boxes or liner board; steel smelted to produce new steel, gypsum used in new wall board; and, concrete crushed for incorporation in new cement production or aggregate.

“This plant represents a 14 million dollar investment in the recovery of materials traditionally landfilled,” says Brian Kent, Transfer Station Manager. “It demonstrates Progressive Waste Solutions commitment to developing new and innovative processes which help move the waste industry to new levels of recycling and environmental responsibility.

Currently, the construction and demolition industry in the Greater Toronto Area (GTA) is estimated to produce nearly 500,000 tonnes of waste annually. The new facility is equipped to process about 20 per cent of the market’s construction and demolition debris, or 100,000 tonnes of waste per year, representing the equivalent of 3,500 tractor trailer loads of material that can be diverted from landfills.

“Through the Education Center located at this facility,” he adds, “Progressive is committed to reaching out to future generations to ensure that the foundations being built upon today will be sustained.”
