it sounds counter-intuitive but it might actually reduce coal use.

 

here's the process:

 

Making cement is an energy-intensive process. To make a tonne of cement, B.C. plants shovel about a tonne-and-a-half of Texada Island limestone and other ingredients into a long kiln, fired by about 140 kilograms of coal per tonne, until it is a semi-molten lava of 1,450 C.

 

That heat, McSweeney said, sets off the chemical reaction in which carbon is stripped out of the limestone to be emitted as carbon dioxide, and creates about 60 per cent of cement-making’s greenhouse-gas emissions.

“(Those) are process emissions,” McSweeney said. “It doesn’t matter how you process — that 60 per cent emissions will always be there.”

 

The lava cool quickly into a hardened, almost metallic material called clinker, which is ground and blended with other elements to become cement, “the glue” that (at 7-to-10 per cent of the mix) binds sand, gravel and water into the essential construction material concrete.

 

It is the 40 per cent of carbon emissions related to firing the kilns that B.C.’s cement makers want to attack with the transition program.

this is interesting too:

 

The tax, at $30 per tonne of carbon dioxide emissions, pushed up the cost of coal — the industry’s primary fuel for its energy-intensive process — to between $53 and $62 per tonne at B.C. cement plants after it was applied in 2008, said Michael McSweeney, president of the Canadian Cement Association.

 

Then they watched as cheaper imports from Asia and the U.S. cut into their market share, from six per cent of the market before the tax to 40 per cent now, McSweeney said.

When Jack Hull was manager of the CRD sewage plant, he noted that while the CRD had originally hoped to get paid by the cement plants for their burning the dried sewage sludge, when the plants looked into it more, they were hesitant because of concern about supply issues. While the sludge keeps coming 24/7, getting it to the cement plants in a steady deliver seemed to be a problem. I guess with today's contract proposal, the CRD is working its way to figuring that out.

 

Might be awhile before we find out how much the cement plants are going to charge to take the sludge, as well as what the truck hauling is going to cost. Just seems weird to be producing Class A biosolids that are going to be incinerated anyway but that might be because CRD knows province really wants that sewage sludge to be absolutely ready to be spread anywhere, with some expectation thats whats going to happen in the end anyway.

Nice that we have to pay someone to take our ****.

[Mike K.]

Isn’t that the thing, eh? First it was to be sold. Now they don’t know who they can pay to take it.

It was a bit of non-event to see the progress down at Clover Point last week, as it's mostly getting covered over now and back to its bunker-like look.  Just a few big pipes that are exposed awaiting connection.

I'm not sure if some of these renderings have been posted here before...

Restoration on top of the dug-up sewage line trench is going ahead. They've paved almost the whole section between Clover Point and Mile Zero now, and the next section to Holland Point is getting ready for it with compacted gravel. I believe those are Garry Oaks that they've planted.

Does anyone know what the difference is between the Clover Point outfall and the one they strung out from Victoria harbour last summer?

[Victoria Watcher]

well the clover point outfall will only be used now in the case of overloads or main plant shutdown. they only strang one pipe from clover point to the new plant. No return pipe. the new outfall only takes newly treated quite clean water.

This project is part of the $17 million pledged by Esquimalt by the CRD in exchange for situating the sewage treatment plant at McLoughlin Point.

CORE AREA WASTEWATER DISCHARGE NOTICE CLOVER POINT:

^Unplanned last night out the short outfall. Regretting my late night dip.

🔺CRD advises of planned sewage discharge; coastal areas in Victoria and Esquimalt will be affected🔺

Construction at the Macaulay Point Pump Station requires screened wastewater to be discharged out the short outfall overnight on June 22, 2020.

The shorelines that will be affected are:

🔹Between Fraser Street and Victoria View Road including Saxe Point
🔹Macaulay Point and McLoughlin Point in Esquimalt
🔹Along Dallas Road between Dock Street and Government Street in Victoria.

As a result of this discharge, residents are advised to avoid entering the waters along the affected shorelines, as the wastewater may pose a health risk.

As a precaution and in consultation with Island Health and the local municipalities, beaches within the affected areas will be posted with public health advisory signs until sample results indicate enterococci levels are below the 70CFU/100mL recreational limit.

A new Macaulay Point Pump Station is being built as part of the Wastewater Treatment Project and will pump wastewater from the western core area municipalities and the Esquimalt and Songhees Nations to the new McLoughlin Point Wastewater Treatment Plant for tertiary treatment.

The remaining crane is being dismantled today.

The small public washroom building at Clover Point is taking shape and was getting its roof on today. 

 

Apparently they are on track to finish most of the public space at Clover Point by end of August.

Looks like CRD wants some fairy godmother to come up with a "beneficial use" idea that will not involve spreading the sludge on the landscape (aside from a periodical interlude piling it into Hartland landfill):   https://www.crd.bc.c...d-pilot-program

A $775-million Greater Victoria wastewater treatment project in the works for more than a decade is less than six months from completion.

Testing has already begun on the Capital Regional District’s new wastewater treatment project and infrastructure is on track to meet the provincial and federal deadlines to have the system operating by the last day of 2020, said CRD board chair Colin Plant.
