The next commitment · Varme waste-to-energy
Fifteen years of garbage is a major financial commitment. Show us the price.
This is where the history becomes a current decision. A new private plant can still depend on a long public commitment. After the co-composter, the question is what Edmonton is promising to pay—and which risks remain with residents if the expected performance does not arrive.
After the composter, the biofuels venture and the organics review, Edmonton has chosen another long-term processing arrangement. The City says its agreement with Varme covers up to 150,000 tonnes of residual residential garbage each year. The January 2024 announcement described a 15-year term and a facility roughly 40 kilometres northeast of Edmonton. The plant would burn garbage to generate electricity, with carbon capture. [23] [24]
At 150,000 tonnes every year, that is 2.25 million tonnes over the term. The public volume statement is not the minimum-payment clause: residents still need to see what Edmonton must deliver or pay for, including when waste reduction leaves less garbage.
Small differences per tonne become enormous commitments.
My current industry estimate for transfer, transport and disposal at Beaver is $70 per tonne. I want that tested against binding offers. For comparison, assume an equivalent all-in waste-to-energy price of $125 per tonne. These are my scenario inputs: neither is an authenticated current offer, and $125 is not a disclosed Varme contract fee.
Every $1 per tonne = $150,000 a year.At 150,000 tonnes annually, that becomes $2.25 million over 15 years. A recurring premium deserves the scrutiny of a major capital project.
Chris’s scenario · 150,000 tonnes every year · 15 years · equivalent all-in scope assumed| Scenario | Per tonne | Annual cost | 15-year total |
|---|
| Beaver delivered disposal estimate | $70 | $10.5M | $157.5M |
|---|
| Waste-to-energy assumption | $125 | $18.75M | $281.25M |
|---|
| Difference to justify | $55 | $8.25M | $123.75M |
|---|
Illustrations, not bids or established savings. Constant prices, undiscounted; no escalation. The annual quantity is the published maximum, not a confirmed guaranteed minimum. Actual tonnage, retained commitments, taxes, service scope and risk allocation change the result. If $125 describes a processing gate fee alone, its transfer, hauling and other excluded services must be added before comparison with the all-in $70 estimate.
On these assumptions, the higher price is about 79% more, not literally twice as much. At a ten-year term the same difference would be $82.5 million; the published announcement says fifteen years. If Council chooses to pay more for environmental benefits, residents deserve to know what each extra dollar buys. In my view, a premium used to make the project viable is a public subsidy. Whether such a premium exists—and its actual size—requires the contract and competitive offers.
The engineering changed. Did our deal change with it?
Emissions Reduction Alberta’s project summary says the waste’s energy content was lower than expected and the energy needed for carbon capture had been underestimated. These findings required a 25% increase in facility scale and changes to the commercial model. ERA reports approximately $2.8 million in study funding. [48]
Varme’s project page now describes a 205,000-tonne annual facility, under development, with a final investment decision anticipated in 2026. That is a plant design figure; the City’s published supply figure remains up to 150,000 tonnes. [49] Council should explain whether the redesign changed Edmonton’s price, waste specification, volume obligation or exposure to delay. A larger plant does not automatically mean a larger City guarantee.
Trucking belongs in the comparison—and the published route is shorter.
Edmonton already consolidates residual garbage into long-haul trucks for Beaver Regional Landfill near Ryley. [27] Varme’s engineering report compares a 180-kilometre round trip to Ryley with 90 kilometres to the proposed plant. It therefore projects lower hauling emissions. The same report says the detailed emissions-reduction calculations were being developed separately. [50, pp. 5–6, 11]
A shorter route reduces the travelling portion of the cost; it does not halve transfer handling or the disposal fee. The question is how much it saves per delivered tonne against any processing premium. Publish the actual routes, payloads, loading costs, fuel use, return trips and disposal of ash and other residues. Compare both options from the same transfer point, including any new infrastructure and backup disposal during shutdowns.
For illustration, saving one truck-hour at an assumed $200 per hour saves $8 per tonne with a 25-tonne payload, or $5.26 with 38 tonnes. Those are sensitivity assumptions, not measured route savings or a quoted trucking rate. Payload, loading and queue time, return travel and the ability to complete another trip determine the actual saving.
For scale, an illustrative 25-tonne payload means 6,000 loaded deliveries a year at 150,000 tonnes. Applying the report’s distances gives 540,000 truck-kilometres to the plant versus 1.08 million to Ryley. Those are scenario calculations, not a fleet forecast; actual payloads, routes and additional movements determine the outcome.
Beaver is an existing commercial alternative. Where is the comparison?
Claystone’s business plan identifies Edmonton as its largest customer, describes its long-haul service, and proposes bundling transport in 53-foot walking-floor trailers with disposal. [51] Its 2022 announcement also confirms that it won Strathcona County’s waste contract through a competitive RFP. [52] There is an established regional procurement market to test against.
The records located establish those services and procurement history, but do not disclose a current Edmonton-specific disposal bid. The comparison Council should publish is the actual Beaver offer and other compliant alternatives, including negotiated fees, escalation, hauling, environmental performance and remaining commitments. Edmonton’s older Beaver agreement included a 70,000-tonne annual minimum and an extension option beyond February 2027. Its current status matters to this calculation. [25]
Compare three systems—not a modern plant against an imaginary open dump.
An engineered landfill contains waste, collects contaminated liquid called leachate and requires ongoing monitoring. Claystone describes synthetic liners, compacted clay, drainage and leachate pipes in its newest Cell 9, built in 2025. Those protections deserve to be part of the comparison, alongside actual methane emissions and long-term liabilities. [79]
A bioreactor is a particular operating approach: controlled moisture accelerates decomposition. In an anaerobic system, collected gas can supply energy. The EPA distinguishes this from simply recirculating leachate. Faster gas production makes effective capture especially important; energy recovery is possible, not automatic. [80]
The Claystone sources reviewed do not establish an operating bioreactor generating electricity or a verified century of remaining permitted capacity. Its expansion material describes a project to sustain operations as existing cells fill. Request approved capacity, gas-collection measurements and any energy project’s operating records before assigning those benefits to Beaver. [81] Nor does a generic “centimetres per decade” claim establish liner performance; use the site’s engineering and monitoring evidence.
Varme’s proposed system burns residual waste for electricity and includes carbon capture. Its project page still describes the facility as under development. [49] The question is whether this project’s complete design, economics and operating performance will deliver—not whether all incineration is a new invention. Compare lifetime net emissions on the same waste mix and time horizon, including escaped landfill methane, actual gas recovery, combustion emissions, capture uptime and storage, transport, residues and net energy exported. Neither a landfill label nor a diversion claim answers that comparison.
There is a regional market to ask.
Alongside municipally controlled Claystone near Ryley, WM lists its Thorhild Landfill at Newbrook, and Waste Connections operates Coronation Landfill. Both list municipal solid waste among accepted materials. These are potential bidders to investigate, not equivalent offers already in hand; permissions, available capacity, haul distance and terms must be checked. [22] [82] [83]
Public support is already part of the economics.
The federal announcement describes a Canada Growth Fund arrangement to buy up to 200,000 tonnes of carbon credits annually for 15 years, starting at $85 per tonne with escalation. [28] At the maximum volume and initial price, that is $17 million annually, or $255 million over 15 years before escalation. These are conditional purchases of carbon credits, separate from Edmonton’s waste-disposal bill.
My concern is that residents could also be supporting the project through a long-term disposal premium. Public ownership of the plant is not required for the public to carry substantial risk. If Edmonton pays more than a competitive alternative, Council should explain what additional service or environmental benefit justifies that difference.
Two revenue pillars. Who carries the risk if one weakens?
The two public commitments worth examining separately are the City’s waste agreement and the federal carbon-credit purchase arrangement. The announced 15-year credit agreement provides a measure of contracted support; it would be misleading to assume that any policy change automatically cancels it. [28] We still need to see eligibility, delivery, termination and change-in-law provisions, and which party absorbs a shortfall.
I am comfortable with waste-to-energy as an environmental option. I am not comfortable treating policy-supported revenue as a substitute for commercial scrutiny. If tipping fees carry a premium and carbon-credit income disappoints, does the project remain viable—and can any of that shortfall come back to Edmonton? The earlier projects are a reason to demand that stress test, not proof this plant will fail.
For an alternative scenario, assume a regional landfill with a permitted bioreactor and effective methane-to-energy recovery. Price the additional equipment, operating controls and financing it actually needs, then compare its full delivered cost and measured emissions with Varme. That scenario must not be mistaken for a verified description of today’s Beaver operation. Nor should we assume zero new capital or risk merely because the landfill already exists.
Commercial haulers need a reason to switch. Who pays if they do not?
In my experience, commercial haulers do not voluntarily trade a cheaper, reliable disposal arrangement for a more expensive one. They compare the full delivered cost, including their routes, transfer facilities and existing contractual obligations. A shorter haul or another commercial benefit could change that calculation. A green label alone will not.
That is why I am skeptical that this plant will attract additional commercial waste at a premium. Edmonton can commit its own residual waste; it cannot commit waste controlled by private haulers or other municipalities. The revised plant design is 55,000 tonnes a year larger than the City’s published maximum supply. Council should identify who supplies that balance and whether Edmonton carries any financial exposure if those volumes do not arrive.
If Edmonton guarantees a price above a competitive alternative to make this project viable, I regard that premium as a subsidy. I am concerned this could become another project whose economics disappoint after the public commitment has been made. The test is the contract: are payments tied only to tonnes accepted, is there a minimum annual bill, and can costs or shortfalls be passed back to the City?
A put-or-pay clause would mean paying for some contracted capacity even when the waste is not delivered. Its existence and terms have not been disclosed in the records reviewed. That is precisely why residents need the agreement and amendments: to see the maximum annual exposure, escalation, backup-disposal costs and exit liabilities before calling the risk private.
The documents residents should be able to examine
- The contract and amendments: price, escalation, minimum tonnage, shortfall payments, waste-quality requirements and termination rights.
- The evaluated alternatives: actual landfill and processing bids, transfer and hauling costs, and the treatment of existing Beaver obligations.
- The revised business case: the financial effect of the larger plant and changed commercial model, including who bears construction delays and operating failures.
- The full environmental comparison: trucking and transfer emissions, combustion, carbon-capture energy use and uptime, ash disposal, and the actual landfill methane-management baseline. Report energy recovery separately from recycling and composting.
I am not satisfied with a diversion announcement as the explanation for a 15-year decision. Show the alternatives, the premium, the environmental benefit and the risk residents retain. Then we can judge whether this is good procurement or an expensive way to buy another promise.
