Restructuring overlooks important environmental legacy: critics – by Hugh Kruzel (Sudbury Star – April 30, 2021)

https://www.thesudburystar.com/

Laurentian is cutting environmental science, environmental studies, ecology and restoration biology programs as it works to balance its books

Sudbury has garnered a reputation around the world as a community that knows how to recover an environment degraded by mining and smelting operations. Most of that know-how was developed by Laurentian University researchers — expertise that will be lost as the university restructures, critics warn.

Laurentian is cutting environmental science, environmental studies, ecology and restoration biology programs – among many others – as part of a process to balance its books.

The university is insolvent, can’t pay its bills and has filed for protection under the Companies’ Creditors Arrangement Act as it restructures. So far, it has cut almost 200 jobs and 69 programs. Many, however, say cuts are a severe blow to the reputation of Sudbury as a leader in landscape revitalization.

Laurentian University cuts world-renowned programs – by Albrecht I. Schulte-Hostedde (Sudbury Star – April 28, 2021)

https://www.thesudburystar.com/

Sudbury is known as the city of lakes and for its famous regreening programs, yet university is slashing expertise in those areas as it restructures

Among the programs closed in Laurentian University’s “restructuring” were environmental science, environmental studies, ecology and restoration biology.

In a city of lakes, where Sophie Mathur has galvanized global youth around the climate crisis, where the regreening of the region has reached near mythological status, an undergraduate student cannot enter into an environmental or ecology program at Laurentian University.

Think about that. Why were Laurentian’s environmental and ecology programs closed?

[Biomining/Bioremediation] Discover: Meet the Sudbury scientist who feeds minerals to microbes – by Mike Commito (Sudbury Northern Life – October 22, 2019)

https://www.sudbury.com/

One-on-one with Dr. Mike: A Q&A with microbiologist Dr. Nadia Mykytczuk

As part of Sudbury.com’s ongoing Discover Series, Dr. Mike Commito, Director of Applied Research & Innovation at Cambrian College, who is often referred to simply as Dr. Mike on campus, is sitting down with researchers and entrepreneurs in Sudbury to spotlight the innovative work they’re doing in our community and beyond.

This week, Dr. Mike had the chance to catch up with Dr. Nadia Mykytczuk on the shores of Ramsey Lake at the Vale Living with Lakes Centre at Laurentian University. Dr. Mykytczuk is a microbiologist who studies how bacteria live and adapt to extreme environments. She holds an Industrial Research Chair in Biomining, Bioremediation and Science Communication at Laurentian University.

When she’s not teaching, Dr. Mykytczuk spends most of her time investigating how bacteria can be used in the mining process. Based on her research, Dr. Myktytczuk believes there is a great opportunity for the mining industry in Canada not only to deploy bacteria in remediation efforts to break down tailings and minimize mine waste, but also to utilize this biomining technology as a catalyst during the extraction process.

Returning green to a blackened landscape: Microbiologist opens MMTS week with talk on mine remediation using microbes – by Karen McKinley (Northern Ontario Business – April 15, 2019)

https://www.northernontariobusiness.com/

Nearly two centuries of mining in northeastern Ontario has left its mark with waste from thousands of mines.

But Nadia Mykytczuk said that waste can be turned into another mining opportunity and at the same time clean up the dirtier parts of the industry’s legacy.

Mykytczuk, a microbiologist, was the guest speaker at the kickoff luncheon for Modern Mining and Technology Sudbury Week (MMTS), hosted by the Greater Sudbury Development Corporation, on April 12.

THE DRIFT: Finding the value in a mine waste pile: Nadia Mykytczuk’s microbes could solve Canada’s industrial legacy issues – by Ian Ross (Northern Ontario Business – April 2, 2019)

 

https://www.northernontariobusiness.com/

Mykytczuk said Canada is behind other countries in making advances
in bioleaching and bio-mining because with the luxury of having
abundant space and mineral wealth, we feel addressing problems of
waste piles isn’t a priority.

To accelerate that research, Mykytczuk is proposing the development
of Canada’s first Centre for Mine Waste Biotechnology for Sudbury,
a research and commercialization hub to allow for solid and liquid
mine waste technology research to be taken from the lab and applied
in the field.

The tiny microbes that Nadia Mykytczuk cultivates in a Sudbury laboratory could have a huge impact in dealing with the legacy issues of mine waste.

The billions of dollars it will take to tackle the problem of treating these industrial legacy sites are not only a burden on governments, but the remediation poses a major headache for operating mines and the introduction of new development.

Laurentian University’s Mykytczuk, an environmental microbiologist at Vale Living with Lakes Centre, has been developing cost-effective, green alternatives to deal with these long-term challenges while finding ways of pulling value from the waste material.

[Philippines Mining] Researcher touts mine site rehab using microbes (Business World – February 7, 2019)

https://www.bworldonline.com/

THE National Research Council of the Philippines (NRCP) proposed on Thursday to rehabilitate degraded mining sites by deploying microbes into the soil, a process called bioremediation.

“There are 50 active metallic mines that will surely become mined out or (contaminated with) mine tailings if there is no responsible mining. That means we will have more abandoned mines,” according to Dr. Nelly S. Aggangan, lead researcher of a study commissioned by the NRCP.

Ms. Aggangan was presenting her 2017 study, “Greening Mined-out Areas in the Philippines,” during the NRCP-Legislative Scientific Forum for Policy Development.

Winter workers: How cold-adapted bacteria can benefit miners – by Christopher Pollon (CIM Magazine – September 06, 2018)

http://magazine.cim.org/en/

Nadia Mykytczuk, Industrial Research Chair in biomining, bioremediation and science communication at Laurentian University, spends a lot of time studying how micro-organisms like bacteria can be used to extract minerals and re-process legacy mine waste, all of which can reduce the environmental liabilities of mining.

As one of the few mining microbiologists focused on cold environments like Canada, she is working to create a Centre for Mine Waste Biotechnology that will nurture the next generation of scientists, companies and microbial mining tools.

CIM: What path led you to your current work at Laurentian University?

Mykytczuk: Very early on I was focused on how microbes work in various environments. While I was an undergrad at Carleton University, I got a co-op placement at the National Research Council looking at vaccine development for various pathogens; for my PhD at Laurentian, I looked at the adaptation of acid mine drainage (AMD) bacteria to acidic and cold environments.

Biosolids rejuvenate mining wasteland: Reclamation project at Vale tailings ponds in Copper Cliff wins award – by Karen McKinley (Northern Ontario Business – July 13, 2018)

https://www.northernontariobusiness.com/

In the decades-long efforts to regreen the Sudbury basin, Vale is reporting its Copper Cliff Tailings Project using biosolids is continuing to be successful. So successful, the groundbreaking project recently won an award and plans are in the works to apply it to other reclamation projects.

The Copper Cliff Tailings Project, a joint effort by Vale and Terrapure’s solutions division, Terratec Environmental, has been running for about five years and continues to show positive and even surprising results.

“We are doing this for two reasons: dust control and covering the area with vegetation for long-term closure plans,” said Glen Watson, superintendent of environment decommissioning and reclamation for Vale Canada. It recently won the Water Environment Association of Ontario’s 2018 Exemplary Biosolids Management Award.

Miniature miners: The rise of microbes in the mining industry – by Kate Sheridan (CIM Magazine – June 21, 2016)

http://magazine.cim.org/

The mining industry largely concerns itself with the inanimate resources of nature: rocks, metals and chemicals. However, there is an increasing interest in how living organisms – small, singlecelled microbes – can breathe life into the mining cycle and limit its environmental impacts.

Monique Haakensen sees a lot of microbes in her role as president and principal scientist at Contango Strategies. Using DNA-sequencing technology, the company provides a microbial community profiling service which identifies the microbiological population at mining projects and provides lab results, guidance on remediation strategies or even suggestions on which living plants will add to an ecosystem to help microbes thrive. And according to Haakensen, microbes are finally getting the respect they deserve for their role in remediation.

“Until this type of technology came about, it was a guesstimate, and because of that there have historically been a lot of failures in passive water treatment because they were not based on informed decisions,” said Haakensen.

[Nadia Mykytczuk – Laurentian University] Research chair on first name basis with microbes – by Ella Myers (Sudbury Mining Solutions – August 22, 2016)

http://www.sudburyminingsolutions.com/

Taking biomining and bioremediation to the next level

Biomining and bioremediation are one step closer to wider use in the mining industry with the creation of a new position at Laurentian University geared towards commercializing the technologies.

As of July 1, Nadia Mykytczuk is Laurentian University’s first industrial research chair in mining, bioremediation and science communications. Ontario is investing more than $630,000 through the Northern Ontario Heritage Fund Corporation to create the five-year research chair position.

“It’s less of a teaching load and more research,” said Mykytczuk. “The impetus was to create a vibrant research program and initiate new projects with industry. The research chair matters because we have a very long legacy of mine waste impacts in Canada and the world, and we now have the opportunity to use biotechnology to help decrease those impacts.”

Mining microbes could unlock wealth, clean tailings – by Mary Katherine Keown (Sudbury Star – August 3, 2017)

http://www.thesudburystar.com/

With luck, ingenuity and some scientific know-how, Sudbury’s tailings ponds could become a new source nickel, copper and zinc. Researchers from Laurentian University, the University of Toronto and the University of British Columbia met at the Vale Living with Lakes Centre on Wednesday at a symposium to discuss biomining research.

“The topic of discussion is developing technologies that aim to remediate waste and effluent waters from mining operations in Sudbury and British Columbia,” Vlad Papangelakis, a professor at the University of Toronto and the project lead of the biomining research, said Wednesday. “We hope to recover some value from locked metals in these residues that will offset the processing costs.”

The value of residual nickel in Sudbury tailings amounts to $7 billion, according to recent world nickel prices. “There is significant economic interest, therefore, to use the eco-friendly processes being developed by (biomining) for remediation and base metal extraction,” symposium organizers said in a release.
