The slippery slope of road salt

We’re all afraid of slipping and falling, especially in winter, so it’s not uncommon to see carpets of salt on Canadian sidewalks and roads this time of year.

But what’s the effect on the environment?

Our bodies need salt, but there is a difference between the stuff we sprinkle in food and what we put on the roads. They’re both sodium chloride, but table salt includes healthy additives like iodine, which deters goiters.

The problem with rock salt (a.k.a. road salt) is that it contains chloride ions, which can have negative effects on ecosystems because once these ions seep into our environment, there’s no way to dilute them and they continue to build up.

And we use a lot of rock salt. According to Environment and Climate Change Canada, the amount of rock salt used on our roads ranges from two to nearly five million tonnes annually. And that’s not including what we’re dumping on sidewalks and driveways.

That salt doesn’t just go away: it leaches into our lakes and rivers and gardens.

It’s “very concerning to someone like me, who’s a freshwater scientist,” said Angela Wallace, project manager at the Toronto and Region Conservation Authority’s (TRCA) watershed planning and reporting division. She said scientists across North America are worried that freshwater, the source of our safe drinking water, “is becoming more and more salinated over time.”

Consider this: the Canadian Water Quality guideline for chloride in freshwater is 120 mg/L. But in and around the Toronto area, there have been measurements of 18,000 to 20,000 mg/L. (Sea water has about 19,250 mg/L.)

And it’s not just in winter. Scientists are finding elevated amounts of salt even in the summer as the ground, which has soaked up all that salt and stored it, slowly releases it into creeks, rivers and lakes.

This can have widespread effects. Fish are disappearing from areas where they once thrived. Frogs — which breed in pools of water, sometimes near roadways — have difficulty breeding. And there’s even fear that birds are consuming it.

“If we’re living in an area where other animals and fish and birds can’t live, that’s going to reflect on … human health impacts as well,” Wallace said.

While there are alternatives, such as beet brine and sand, the fact is that salt is simply cheaper. Many argue, however, that its highly corrosive nature — which damages roadways, bridges and buildings — actually makes it more costly in the end.

According to Tim Van Seters, manager of TRCA’s sustainable technologies evaluation program, there are several ways to help the environment on this issue.

One is to use less salt. “There’s a belief that you need to cover the entire surface with salt so that you can’t see the pavement anymore, otherwise it’s not effective,” said Van Seters. “But that’s just not true.”

Another is to stop using salt to get out of shovelling. “Shovel early and often,” said Van Seters. “Don’t let the snow melt and then refreeze because that’s when you need to really use a lot of salt to get that off.”

Van Seters also said municipalities could deputize people, much like parking enforcement officers, to ensure citizens aren’t over-salting.

“No one’s saying to eliminate salt altogether,” said Van Seters. “We just have to use it better.”

We want to hear your ideas

Many of you have written in to offer kind words (thanks!) and suggestions for ways to improve the newsletter. Some of you have also used the opportunity to propose ways of solving some of the big environmental problems that exist.

One of the interesting emails we got this week was from a reader who was thinking about ways to reduce energy use in buildings.

“As a longtime renter of different apartments in Toronto, I am wondering why everywhere in buildings the temperature is so high that I need to keep windows open even in winter. Would it not be more efficient to put in a system that allows each renter to change temperature to a lower level, hence creating a lower expenditure on heating?”

The reader poses an interesting scenario. Is it feasible? It’s something we’ll take a look at in an upcoming issue.


Researchers build bank of genetic codes to protect Amazon rainforest

In a battle to protect the Amazon jungle, the world’s largest rainforest, researchers are building a giant database of genetic codes to catalogue material contained in the plants and animals there.

From new medicines and cosmetics to the rubber in car tires, genetic material extracted from the forest has spurred billions of dollars worth of new inventions.

Spread across nine countries, including Brazil, Colombia and Peru, the Amazon is home to one in 10 of all known species on Earth, according to the World Wildlife Fund. Known as the “lungs of the planet” for its role in sucking carbon dioxide out of the atmosphere, the Amazon also plays a crucial role in stabilizing global weather patterns.

Amazon residents, however, often have few options other than clearing the forest to raise crops or logging to earn a living.

“That doesn’t work when we look at things from an earth systems point of view,” said Dominic Waughray, who heads the Amazon Bank of Codes project for the World Economic Forum (WEF).

Backed by technology researchers, scientists and the Switzerland-based WEF, the Amazon Bank of Codes aims to change that dynamic of resource exploitation by billing companies who want to use genetic material taken from the forest.

Waughray said the project could be up and running by the end of 2020. Once in place, investors who want to use genetic material from the Amazon will be able to log onto the code bank and purchase the specific genetic strains they want to use for a small fee.

Through cellphone banking and other digital tools, royalty fees will be transferred directly to local residents and government authorities, giving people in the Amazon a financial incentive not to cut the trees, Waughray said. In Brazil’s part of the Amazon alone, an area larger than Germany has been deforested since 1988, according to Brazilian government data.

The royalties will be transferred to governments and local communities in the Amazon through blockchain, the same online ledger system that underpins the digital currency bitcoin. If properly managed, royalties from genetic material could end up providing local residents with far more money than ranching or farming, Waughray said.

Brazil’s new president, Jair Bolsonaro, has pledged to open swaths of the Amazon to mining and agribusiness, but has made no move to stop the bank of codes.

Waughray predicts biotechnology based on better mapping of genetic resources could help fuel a “fourth industrial revolution.”

Imagine what it means to be a country with a high biological endowment like a Costa Rica, Brazil or Colombia, where we traditionally think of ranching, soy and timber,” Waughray said.

As a result of this bank of codes, “we think of the habitat itself as being a valuable banker to feed the 21st century.”

The Big Picture: Geothermal power

Last week, Prime Minister Justin Trudeau announced that the federal government would kick in more than $25 million to fund Canada’s first geothermal power facility. The plant, located near Estevan, Sask., will generate five megawatts of power, enough to power around 5,000 homes. Geothermal energy taps heat beneath the earth’s surface and is considered clean and sustainable. Here’s a look at the world’s biggest producers of geothermal energy.

Hot and bothered: Provocative ideas from around the web


Here’s one way to keep the planet from warming

Good news: It’s still possible to keep the Earth from warming above 1.5 C pre-industrial levels.

That’s according to a new study from the University of Leeds, which suggests the solution doesn’t involve untested, futuristic technologies or even giving up your gas-guzzling SUV while it’s still road-worthy.

All we have to do is not repair or replace existing carbon-emitting infrastructure with more of the same. That means aging gas or coal plants, cars and trucks, airplanes and ships — as well as a few less obvious things.

The report said that if we start now, there’s a 64 per cent chance we can stay under the limit of 1.5 C of warming set by the Paris agreement to avoid the most dire consequences of climate change. As Chris Smith and his team of researchers at the University of Leeds write in Nature Communications, “Limiting warming to 1.5 C is not yet geophysically impossible.”

But if we keep repairing and/or building fossil-fuel-based power plants and vehicles, as well as breeding beef cattle, even until 2030, staying under 1.5 C becomes more unlikely. (Although there would still be a good chance we could stay under 2 C, which was the less-ambitious Paris target.)

Smith acknowledges in a separate article in The Conversation that some challenges make this type of plan harder than it sounds. For example, there aren’t any viable alternatives yet to fossil-fuel-powered planes.

One of the study’s assumptions is that building zero-emissions replacements, such as wind and solar, wouldn’t in and of themselves generate emissions — which they largely do at the moment. And while we can wait up to 40 years for our coal plants to break down, the whole world would have to give up beef within three years and completely stop deforestation right now — unlikely.

Still, it makes limiting climate change by quitting fossil fuels look almost achievable. Perhaps part of the solution is resisting the urge to replace dirty infrastructure with … more dirty infrastructure.

The ‘Maple Majestic’ wants to be Canada’s homegrown Tesla

Editor

Look out Tesla, Canada has a homegrown electric sedan on the way. Well, that’s if AK International Motor Corporation can drum up enough investment to make its EV a reality. Dubbed the “Maple Majestic,” the vehicle is a battery-electric designed to “excel in extreme climate performance without adversely affecting the climate, as befits a vehicle from Canada,” according to its website.

What’s in a name? — The company says the maple leaf is a “symbol of Canada’s warmth and friendliness towards all cultures,” while “majestic” refers to the country’s “status as a Constitutional Monarchy.”

That patriotism carries over into Maple Majestic’s parent company’s lofty goals. AK Motor founder Arkadiusz Kaminski says he wants the company, which he founded in 2012, to become “Canada’s first multi-brand automotive OEM,” and that the “Maple Majestic is intended to be Canada’s flagship brand of automobiles on the world stage.”

Partnerships are key — “We acknowledge that the best chance for the Maple Majestic brand to succeed, lies in continuing to build the relationship with Canada’s parts suppliers and technological innovators, whether they be academic institutions, corporations, or individual inventors,” the company explains. “We are currently seeking partners in automotive engineering, parts manufacturing, automotive assembly, electric propulsion technology, battery technology, autonomous technology, and hybrid power generation technology.”

In other words, don’t expect to be able to buy a Maple Majestic any time soon… and don’t expect to pour over 0-60 mph times, power output, range, or other key stats, because those don’t currently exist. For now, all we have are pictures and a short video clip. But at least those are arresting.

Houston-based energy technology company Quorum Software will merge with a Canadian tech firm to bolster its presence in oil and gas services.

Quorum announced Feb. 15 it plans to merge with Calgary, Alberta-based Aucerna, a global provider of planning, execution and reserves software for the energy sector. The combined firm will operate under the Quorum Software brand.

Gene Austin, CEO of Quorum Software, will continue in his capacity as chief executive of the combined firm. Austin, former CEO of Austin-based marketing tech firm Bazaarvoice Inc., became CEO of Quorum in December 2018.

Aucerna co-founder and CEO Wayne Sim will be appointed to the Quorum Software board of directors. Both companies are backed by San Francisco- and Chicago-based private equity firm Thoma Bravo.

“Over the last 20 years, Quorum has become the leading innovator of software deployed by North American energy companies,” said Austin. “Today, Quorum is expanding the scope of our technology and expertise to all energy-producing regions of the globe. Customers everywhere will have access to a cloud technology ecosystem that connects decision-ready data from operations to the boardroom.”

In addition to the merger announcement, Quorum Software announced it had entered into an agreement with Finnish IT firm TietoEvry to purchase TietoEvry’s entire oil and gas business. The agreement, which includes hydrocarbon management, personnel and material logistics software and related services, is valued at 155 million euros, or $188 million, according to a statement from TietoEvry.

“Our three organizations complement each other — from the software that our great people design to the energy markets where we operate,” said Sim. “Our new company will be able to deliver value to our stakeholders, while accelerating the growth of our combined business and the energy industry’s software transformation.”

The combined company will serve over 1,800 energy companies in 55 countries, according to the announcement. With its headquarters in Houston, Quorum will continue to have a significant presence in Calgary and in Norway, the headquarters for TietoEvry’s oil and gas software business. Quorum will have other offices throughout North America, Latin America, Europe, Asia and the Middle East.

As of Sept. 30, 2020, private equity firm Thoma Bravo had more than $73 billion in assets under management. In late December 2020, Thoma Bravo agreed to acquire Richardson, Texas-based tech firm RealPage in a roughly $10 billion acquisition.

Piece of Kitchener technology lands on Mars on Perseverance rover

KITCHENER — A piece of Kitchener technology has landed on Mars, thanks to NASA’s Perseverance rover.

The rover settled on the planet’s surface on Thursday afternoon. It’s been travelling through space since it was launched from Cape Canaveral, Fla. in July.

“The whole idea of being on a device that we’re sending to another plant with the express mission of looking for traces of past life, it’s pretty mind boggling actually,” said Rafal Pawluczyk, chief technical officer for FiberTech Optica.

The Kitchener-based company made fibre optic cables for the rover’s SuperCam that will examine samples with a camera, laser and spectrometers.

“The cables that we built take the light from that multiplexer and deliver it to each spectrograph,” Pawluczyk said.

The cables connect a device on the rover to the SuperCam, which will be used to examine rock and soil samples, to spectrometers. They’ll relay information from one device to another.

The project started four years ago with a connection to Los Alamos National Lab, where the instruments connected to the cables were developed.

“We could actually demonstrate we can design something that will meet their really hard engineering requirements,” Pawluczyk said.

The Jezero Crater is where the Perseverance rover, with FiberTech Optica’s technology onboard, landed Thursday. Scientists believe it was once flooded with water and is the best bet for finding any evidence of life. FiberTech’s cables will help that in that search.

Ioannis Haranas, an astrophysicist and professor at Wilfrid Laurier University, said the rover isn’t looking for “green men.”

“They’re looking for microbial, single-cell life, any type of fossils and stuff like that,” Haranas said. “That’s why they chose a special landing site. This could be very fertile land for that.”

“It’s very ambitious,” said Ralf Gellert, a physics professor at the University of Guelph.

Gellert helped with previous rover missions and said it’s the first time a Mars rover has landed without a piece of Guelph technology on it. While he’s not part of Perseverance’s mission, he said the possibilities are exciting.

“Every new landing site is a new piece of the puzzle that you can put together with the new results that we have from the other landing sites,” he said.

“It’s scientifically very interesting because, even though we don’t have an instrument on that rover, we can compare what the new rover Perseverance finds at this new landing site,” he said.

Now that Perseverance has landed on Mars, FiberTech is looking ahead to its next possible mission into space.
