The Recycling Economy

Resource Recovery Partnership Conference

For the sixth year, I’ve been helping organize the “Resource Recovery Partnership” conference in collaboration with industry, government, and academic colleagues. This year’s event is on Thursday September 19, 2019, and registration is free for either in-person or webcast attendance. The final agenda is available, and anyone interested in the ideas behind sustainable materials, recycling, circular economy, zero waste, or materials and energy recovery might want to attend some of the webcast sessions. There are a range of speakers and panelists covering various aspects of policy development, technologies, and current statistics and trends. The talks are not highly technical, and anyone could benefit from some of the insights available here.

As our landfills (and oceans) fill with wastes, it has become clear to most people that solutions are needed to reduce wastes and to recover some value from the remaining waste materials. This is easier said than done, and requires a comprehensive approach incorporating technology, smart policies, economic drivers, and societal buy-in. These conferences have tried to bring together people from a wide range of backgrounds and interests, to try to advance progress in waste reduction. It’s a long and slow progress, but momentum seems to be building around the globe.

U Waterloo #13 Worldwide!

The latest university ranking scheme is one from Times Higher Education (THE) and their University Impact Rankings for 2019.  This new ranking is based on the 17 UN Sustainable Development Goals and how well each university contributes towards meeting those goals. According to a news summary, Waterloo does particularly well on 4 of the goals, namely Partnership for the Goals, Sustainable Cities and Communities, Climate Action, and Reduced Inequalities.

Listing of the 17 Sustainable Development GoalsOverall, Canadian universities score well in these sustainability rankings, with McMaster #2, UBC tied for #3, University of Montreal tied for #7, York #26, and Toronto #31.  McGill comes in somewhere in the 101-200 range.  I haven’t spent any time looking at the details yet, so I’m not sure what contributes to some of these rankings.

A lot of the “top” US universities didn’t participate in these rankings, so it’s hard to make many comparisons.  The top 3 ranked US colleges in these rankings were U of North Carolina at Chapel Hill at #24, Arizona State at #35, and U Maryland Baltimore County at #62.  I’m aware of these places because they have strong STEM programs and research activities, but most Canadians probably aren’t aware of them.  Perhaps next year more US colleges will participate.

In general, sustainable development is an important goal and increasingly a part of engineering education and practice.  Engineers Canada, the body responsible for accreditation of engineering education in Canada (among other things), has a national guideline on sustainable development for professional engineers published in 2016.  Various bits and pieces of this are already built into our curriculum for chemical engineers (and I assume in other disciplines), but there are further improvements we continue to work towards.

Autism and Air Quality

/ profbillanderson / Leave a comment

Autism, or more accurately Autism Spectrum Disorder (ASD), is in the news and public view a lot in recent years.  According to some recent reports, it is now diagnosed in 1 out of 68 children (1.47%) in the U.S.  Reasons for the apparent increase in diagnoses over recent decades are complex, but they lead us to wonder what is happening and what are the causes?

Recent scientific literature suggests that the specific causes are largely unknown, but there is a very strong genetic component (heritability of 80%).  Unfortunately, even the genetic aspects are very uncertain and probably highly complex, not just a simple set of genes like the ones that determine your eye colour.  Although genetics may play a large role, there are also indications that environmental factors are involved, perhaps in some sort of interaction with the genetic factors.

The popular and social media keep going in circles about vaccines, a factor for which there is no reliable scientific evidence at all.  At the same time, there seems to be complete ignorance of a growing body of scientific literature linking ASD with air quality.  A quick search through peer-reviewed scientific literature using the Scopus database shows at least 160 papers that mention “autism and ‘air pollution'” somewhere in the publication over the past 20 years.

I don’t know a lot about ASD, but I can comment on air pollution and so here I’ll discuss what I see from some of this literature.  Much of the research literature is only fully available if you have access to a university library (like me), but I’ll try to provide some links to at least the summary or abstract of the studies.  Much of this literature is highly technical however, so don’t worry if it’s not so easy to digest.

Ontario’s New Climate Change Plan

/ profbillanderson / Leave a comment

The new Ontario government recently released their plan to tackle carbon emissions and climate change.  This comes after scrapping the previous government’s relatively new cap-and-trade scheme that was set up in collaboration with Quebec and California.  Below I’ll give a detailed analysis of various parts of the plan, but here is my high level overview.  There are some promising bits and pieces (without knowing a lot of details yet), but it is relatively unambitious and somewhat odd in its approach.  This new government has generally focused on reducing regulation and taxpayer-funded spending, but this plan implements additional regulations and uses tax money to subsidize industry.  This seems inconsistent.  If you want to see the plan and comment, here is the link.  Now for my detailed analysis… Continue reading →

Ontario Climate Change Plan Input

/ profbillanderson / Leave a comment

The new Ontario government quickly trashed the beginnings of an approach to reducing carbon emissions and climate change, i.e. a “cap and trade” system in collaboration with California and other provinces and states.

Now the government is looking for input into their promised new and improved approach, which you can provide at https://www.ontario.ca/form/tell-us-your-ideas-climate-change .   It’s open until November 16 2018.

A recent report has re-confirmed that we only have until about the year 2030 to substantially reduce carbon dioxide emissions, before the goal of keeping the global average temperature increase to less than 1.5 degrees Celsius becomes physically impossible.  (This is actually not surprising news since it’s been known for many years in the scientific literature, while the world at large continues to do nothing substantial).

Young people, and parents or grandparents of young people, should be commenting because these are the ones who will be inheriting the problem and all of its consequences over the next few decades.

Long-term effects of forest fires pose threats to drinking water

/ profbillanderson / Leave a comment

An interesting article about my colleague Prof. Emelko’s research.  I’m somewhat jealous that she gets to fly in a helicopter!

Forest fires are sweeping North America with detrimental environmental, economic and human impacts. A research team, led by University of Waterloo Engineering professor Monica Emelko, will receive $5.5 million from the Natural Sciences and Engineering Research Council of Canada’s (NSERC) Strategic Partnership Grant for Networks to provide new knowledge on the impacts of different forest management strategies on drinking water source quality and treatability.

Garbage Research

/ profbillanderson / Leave a comment

Over the past month I’ve spent some time on research topics related to garbage.  Or more accurately, energy from waste, sustainable materials management, circular economy issues, reduction and recycling.  To the public, such things may not be as exciting as self-driving cars, but as landfills, oceans, and beaches fill with wastes they are becoming more noticeable and pressing issues.

First, I helped to organize our 5th annual Resource Recovery Partnerships Conference here at Waterloo in late June.  Over two days, we had lots of presentations and networking among academic, industrial and municipal government people discussing various issues related to waste reduction and management.  Shortly after that, I attended the Air & Waste Management Association’s annual conference, held in Hartford CT.  There, I saw a number of interesting presentations on “zero waste”, sustainability, and case studies of projects.  Between these two events I learned a few things that I can summarize below: Continue reading →

Consider Geological Engineering

/ profbillanderson / Leave a comment

Waterloo has a Geological Engineering program that seems to get overlooked by many prospective applicants for some reason.  Maybe because it’s small, only about 25 to 30 available spaces.  Or maybe people just don’t realize what it’s about.  So I talked with the current director of the program, Prof. Stephen Evans, and he gave me some insights and nice photographs of geological engineering examples.  I’ll summarize a few key ideas about the Geological Engineering program:

  • It’s the intersection of civil engineering and earth science, and provides the ability to assess how the changing earth might affect the integrity and long term security of civil engineering structures and our societies.
  • There are a wide variety of jobs involving foundations for major buildings and structures, natural resource management (mining, hydroelectric, oil & gas), infrastructure construction and safety (dams, reservoirs, roads, railways), and managing geohazards (landslides, earthquakes, volcanoes).
  • It may be for you if you like travel, sustainable design, engineering to minimize natural hazard risks, and the interactions of infrastructure and nature.

Below are some pictures Prof. Evans has taken of geological engineering examples.  Several of these are from field trip locations our students have travelled to in past years.

 

Field trip to Iceland to see Geothermal Energy (and tourism)
Field trip to Lake Palcachocha, Peruvian Andes to see glacial lake engineering and climate change effects.
Field trip to Antamina Mine, Peruvian Andes.
Field trip to open pit mine in Peru.
Rockslide in Rocky Mountans, Jasper National Park, Alberta, Canada.
Field trip to Jasper National Park for geological mapping.

Recent US College Fair and Outreach Activities

/ profbillanderson / 3 Comments

For 11 days in October we traveled across the U.S. to attend the NACAC College STEM Fairs in Santa Clara CA and New York city.   These were very good events, and we had the opportunity to meet a lot of high school students and families.  Some had heard of Waterloo, but many others had never considered the idea and potential benefits of studying in Canada.  So we had some good conversations, especially around the concept of Waterloo engineering’s co-operative education system, alternating study with up to 6 paid work opportunities.   It looked like very few (if any) schools sent faculty to these fairs, but I thought it was worthwhile for me to be there because I could discuss the program content in depth, as well as more general thoughts on engineering education and career paths.

In addition to attending the college fairs, we also did some outreach workshop activities.  Waterloo has a long history of outreach educational activities, especially through our Centre for Education in Mathematics and Computing  (CEMC) who do mathematics classes and workshops in a wide variety of schools and locations.    Borrowing from their ideas, I created several engineering design workshops based on case studies from our Waterloo Cases in Design Engineering group, headed by Prof. Lambert.  With some adaptation for high school level and time limitations, we cover some math, physics and/or chemistry, and spend some time having the students come up with preliminary design ideas for a rocket, or rainwater harvester system, or some industrial equipment.  These are all based on things our own students have done during workterm employment, and it is meant to be an introduction to engineering design concepts and different approaches to problem-solving.

During our trip we engaged with about 7 classes in several schools, including Design Tech High School in San Mateo, Harker School in San Jose, Léman Manhattan Preparatory School in New York, and the United Nations International School in New York.  Although there was interest from other schools, we couldn’t squeeze in any other schools in our limited timelines this year.

We also had a very nice evening event held at Bellarmine College Preparatory school in San Jose.  A number of prospective students and families were able to meet some of our engineering and mathematics alumni and a few of the hundreds of co-op students currently working in the Silicon Valley area.  (Many thanks to our alumni and students for volunteering their time to attend!)

Finally, we had a couple of good meetings with quite a few independent college counselors to explain about Waterloo and co-operative education.  In Canada, such people are rare but in the U.S. they are more commonly employed by families to help them sort through the myriad of possible options for college.  It was an opportunity for us to explain what type of student and background might be the best fit, and to explain more about the Canadian admissions process and timelines.  For example, in the U.S. the application deadline is often November 1, but our engineering applications are open until February 1, so there is still lots of time for applicants in the U.S. to look into Waterloo or other Canadian schools.

We will be returning to the Houston area in early November for the last NACAC Stem Fair, after which we’ll return to Waterloo to start ramping up the admissions process for 2018.

 

University of Waterloo students make a big splash in the 2017 AquaHacking semi-finals | Water Institute

/ profbillanderson / Leave a comment

An interesting competition event showcasing environmental water quality innovations by student groups.  Sponsored by the Water Institute at Waterloo, one of the research centres I belong to.

The AquaHacking 2017 semi-final competition unfolded last week at CIGI. By the end of the evening, five teams were chosen to move on to the final competition at Waterloo on September 13. It was a difficult decision for the five judges, as all 17 teams that competed offered innovative ideas that tackled the challenges and opportunities facing Lake Erie.
