5REDO's CTO Gave a Lecture at Leading Change Forum
Our CTO, Fabien, presented a lecture on "Life Cycle Thinking and the Physical Basis of a Sustainable Economy" at the Leading Change Forum 2024 in Vancouver. The event brought together young leaders in sustainability to engage in conversations and discussions towards collaborative actions for increasing climate resilience and restoring our natural environment.
In his interactive lecture, Fabien illustrated the principles underlying the chemical economy of our planet, the impact that human activity has on it, and the tradeoffs that will need to be made to achieve sustainability at the planetary scale. The lecture also introduced life cycle thinking and the role it can play in ensuring progress towards sustainability.
The Hidden Value of a Waste Audit
Many companies are used to conducting audits of their activities, whether it’s for efficiency, employee satisfaction, or ways to save money. In an era where more and more businesses are transitioning to sustainable practices, why not add waste—its creation and how to reduce it—to regular auditing work?
Reducing waste is a broad goal, something many organizations want to prioritize. To do so effectively, it’s important to have clear, accurate information about where to start, and that’s what a waste audit can provide. Business Development Canada (BDC) defines a waste audit as a study of the quantity and type of waste produced, and also what’s being done with it, breaking down “how much waste is being recycled, composted or sent to landfills or for incineration.”
In Ontario, many businesses, from hotels to construction giants are already required to conduct a waste audit, and devise what the province calls a Waste Reduction Workplan.
Often, businesses are unaware of how much waste they’re generating in the first place, or that it might be impacting their bottom line—and that there are sustainable alternatives that can actually save money in the long run.
Though it sounds rigorous, a waste audit can actually be as simple as a small company assessing the weight of what goes into each of their office waste bins and checking for contamination, which is a major problem in many waste streams, no matter the size.
So, where’s the real opportunity in it? First, it allows the best information possible to know how to move forward. Rather than jump in and make a costly, or even inefficient switch to a new type of packaging, for example, a waste audit can show what you’re already doing well, and where you can improve. It’s like making the transition at home to sustainable clothing: it’s not about throwing out all your existing clothes and hustling to buy up ethical swaps, as that may have useful items end up in landfill, defeating the purpose. Like so much of the transition to a circular economy, it’s about taking strategic steps toward change.
Waste audits may fly under the radar, since they aren’t the most attractive, presentable action items that can be easily marketed to customers. But they’re crucial in that they provide a closer look at daily operations, providing accurate information for how to build lasting sustainable practices. No, looking in your garbage can isn’t the first thing that comes to mind when considering how to improve habits—but with a waste audit, trash becomes less of a hassle and more of an opportunity to generate value, long-term.
What Eco-Labelling Can—and Can’t—Do for the Environment
Pick up any product nowadays, and you’re likely to find messaging related to the environment. Whether it’s a vague claim about being “green” or a certification stamp—Sustainable Forestry Initiative, B-Corp, non-GMO—it seems everything from toothpaste to furniture is making a statement about sustainability. With so many ways to call a product “eco-friendly”, limited regulation and growing consumer desire for responsible consumption, the risk of greenwashing with these kinds of labels runs high.
Can there be a real impact to eco-labelling? How can consumers, businesses and decision makers wade through the many terms and symbols to make the best choice for the planet?
As circular economy experts, we always like to clarify terms and information to get a true sense of what something can or can’t do for the environment. That’s challenging here, as not every company or producer is required to give full information about why they use certain labels, and it can be difficult to gauge the validity behind them.
Moreover, there’s the plain fact that just because something has an eco-friendly label, that doesn’t make it truly sustainable. We wrote about this in terms of the recent carbon labelling trend, and here, let’s take the Sustainable Forestry Initiative label that appears on many paper products as an example. With the sheer amount of demand for everyday items like toilet paper or cardboard, some would argue there’s no true “sustainable” way to harvest the volume of trees currently needed to feed supply.
Also, even if one material is sourced sustainably, the whole product might not be. Take a box of store-bought pasta; the cardboard could be sustainably sourced, but other elements like the plastic sheet that allows you to see the product inside is not. Same goes for furniture—while the wood or paper used might be sustainable, the chemicals used to coat the furniture can still be harmful.
Of course, no product is perfect, but this is where environmental labelling can unfortunately become a case of greenwashing. People might select a product based on a genuine desire to do better, only to be taken advantage of by what many companies may see as a trend.
So, what can consumers do? A good rule of thumb is to look for third-party certifications, not just words used as part of product marketing. For example, the United Nations Environment Programme offers a short, helpful description of what eco-labelling is really meant for, including what’s categorized in the International Organization for Standardization.
Ultimately, eco-labelling often falls into the unfortunate category so many of us wrestle with when it comes to the environment, which is that it’s “better than nothing”. But as awareness and education grows across the globe, consumers hold more power than ever before, both in what they buy and what they leave on the shelf.
It’s Time for ‘Reuse’ to Get the Innovation It Deserves
Of the three action items in the popular phrase ‘reduce, reuse, recycle’, one is often neglected: reuse. While reducing consumption and improving recycling systems is important, reuse deserves a closer look—from textiles to appliances, reusing everyday items can be a subtle but powerful choice for sustainability. This is especially evident when it comes to packaging for everyday items like groceries, takeout food and cleaning products.
The government of Canada estimates that plastic packaging (including single-use) makes up more than 37% of plastics on the market, but represents more than 50% of plastic waste generated—less than 14% of which is recycled. To date, most approaches to reducing packaging waste tend to focus on addressing overreliance (such as Canada’s single-use plastics ban) or improving recyclability. However, as we’ve explored in the past, recycling has its limitations, and there’s not yet a robust market for affordable, truly compostable products to fill the gap.
This is where reusable packaging comes in, an option that can not only meet current needs, but be cost effective for businesses and consumers if done correctly. The company Reuse Refill Canada estimates that replacing just 20% of the country’s single-use packaging will not only reduce more than 300,000 tonnes of annual waste, but could create a financial opportunity of more than $700 million.
So, why aren’t reuse systems more widely implemented? Much of it can be chalked up to convenience. To facilitate the reuse of a container, a business must implement extra education for the consumer and factor in transportation costs, storage space and resources to clean or repurpose items. For consumers, there are extra steps involved to return items, which many unfortunately won’t, even when there is a convenient option like a drop off location nearby. There’s usually also an initial cost to consumers, either because a reusable container is pricier, or simply because to refill or reuse an item, that first purchase is required.
Still, widespread innovation is ramping up to introduce reusable packaging into various industries. Food takeout services are attempting the shift, like the recent SkipTheDishes pilot program in Calgary, where the app partnered with a local reusable packaging business, allowing users to order from participating restaurants and return packaging at one of 13 recycling centres. Uber has taken on similar projects, and companies like Friendlier, Crisper Kits, Muuse, and DreamZero all work in the food industry space to help businesses switch to reusable packaging, and get consumers to participate in an effective way. Even grocery giant Loblaws recently partnered with Loop, an online service that allows customers to buy some groceries in reusable, refillable containers.
Clearly, businesses are seeing dollar signs in the opportunity, while addressing growing customer concerns about reducing wasteful packaging. Like many sustainability shifts, unless reusing is convenient, easily integrated, and well managed, it will be challenging to widely adopt—but it’s more than worth the effort.

Ending Food Waste for Good
In our first piece on food waste, we established that it’s a major global problem, one soured by the fact that millions face hunger and a rising cost of groceries. Luckily, there are many initiatives, from public health campaigns, startups, and social media groups seeing great success in the mission to end food waste.
For grocers and food producers, reducing waste can be challenging not only because of sell-by and expiry dates, but the maneuvering required to get unsold food out to where it’s needed. In recent years, a variety of businesses have stepped in to fill this need. Denmark-based Too Good To Go and Toronto-based company Flashfood connect users (via their apps) with surplus food at local grocers and restaurants, and offer options like “surprise bags” and discounted food close to its sell-by date. In the UK, Oddbox works with farms to identify produce at risk of going to waste—largely due to its odd shape—and puts together subscription or pickup boxes for nearby customers.
Grocers are also making changes, with Toronto-area chain Longo’s already hitting a target of more than 75% food waste reduction, by utilizing services like Too Good to Go, upcycling unsold ingredients, and using various metrics to gauge demand, to ensure they only supply what will be bought and used. Costco Canada works with more than 400 local organizations to donate both non-perishable and perishable goods to places in need, and at some facilities, food waste is used to create compost and fertilizer that is then sent to local farms.
While activities are going on across many industries, Canada’s National Zero Waste Council found that cohesion is needed to tackle food waste in a more significant way. After reviewing input from hundreds of stakeholders, the Council created a Food Waste Pyramid, ranking steps toward reducing food waste in the country; prevention came out on top.
The Council states that a national target is needed so that food producers, stores, and municipalities can have a framework to work from, since currently, waste reduction efforts vary widely. Another major step identified is reducing confusion over food labels, so consumers can better discern between “sell by”, “best before” and so on. This would not only reduce waste at the household level, but make it easier for suppliers to move unsold perishable products to where they’re needed.
Of course, amidst larger structural change, individuals play an important role, as we know food waste at the household level is significant. A poll from the Canadian Centre for Food Integrity found individual consumers feel they’re “most responsible” (at 59%), for reducing food waste, closely followed by restaurants and grocery stores. With this in mind, a number of efforts target consumer-to-consumer waste reduction, such as Facebook groups like Buy Nothing, which facilitate swaps of used or surplus items, including food.
Individuals can also reduce food waste by being more judicious when grocery shopping and not over-buying. Cooking at home rather than ordering in, freezing or better preserving produce in your fridge, and also composting when necessary—and properly—is important. If you have an at-home garden, you can also use food scraps to create compost or enrich soil. Making use of local food banks and community fridges to donate unused food is also a great option.
Amidst efforts to bring the circular economy into our everyday lives, food offers many options; with so many people hungry, there’s more reason than ever to make sure nothing goes to waste.

Many semi-durable and durable consumer goods are composed of plastic. Yet, plastic pollution is one of the most pressing environmental issues as it harms oceans and marine biodiversity. This state of affairs is worsened because plastic recycling rates remain low. Therefore, one commonly proposed solution is to improve plastic waste management to create a circular plastics economy. However, focusing on recycling management alone overshadows the consumption component and how consumers might contribute to recycling efforts. Although not alone in the overall recycling process, consumers are critical stakeholders in this because through their disposal behavior, they determine the responsible discarding of plastic through recycling. The significance of consumer engagement in driving circularity has been strongly emphasized in extant research and practice. Shifting from a linear plastic economy toward a circular one requires the active contribution of all stakeholders, especially the consumer. Hence, given the centrality of consumers' role, this paper provides an overview of the themes related to consumer engagement with plastic recycling. More specifically, the paper reveals three layers of influence on consumer plastic recycling behavior: (1) macroenvironmental factors, (2) situational factors, and (3) individual factors. This review provides scholars, practitioners, and decision-makers with better insights into the themes to consider in order to spur consumer engagement in plastic recycling.

Food Waste and the Negative Feedback Loop
In mitigating climate change, there’s often a tension—one we’ve highlighted before at 5REDO—between individual and collective action. What can individuals do to lessen their environmental impact, and when should efforts be directed toward the larger forces at play? This question is challenging, as individual action can sometimes feel futile. But as the case of food waste shows, it can have an outsized impact—for better and worse.
With groceries at their highest prices in decades and food bank use across Canada at an all time high, it’s unfortunate that food waste continues to be a major problem. The province of Ontario alone generates nearly one million tonnes of food waste every year from the production to household level, according to the National Zero Waste Council. What’s perhaps even more surprising is that nearly half of that waste is created by individual consumers. Even in areas that have an organic waste collection program, food scraps still comprise nearly 31% of residential waste that ends up in the province’s landfills.
Food waste encompasses both unused or uneaten scraps and ingredients thrown away in homes, restaurants, grocery stores, and food production sites, and also scraps that are put into green bins, but, for a variety of reasons, not ultimately composted.
While food waste is of course a social issue, it’s also an environmental one, as organic waste that ends up in landfill emits methane as it breaks down—a greenhouse gas up to 25 times more harmful than CO2. Excess food waste both leaves people needlessly hungry, and hurts our environment. (There are a number of initiatives in place, both in everyday households and industry, to mitigate food waste, which we’ll cover in a subsequent article).
It’s useful to understand why food waste happens, and the complex reasons it remains so prevalent. First, poor waste diversion is an important factor. The 2021 Census tells us that 76% of Canadian households use at-home green bins, a more than a 50% increase since 1994. This is significant, since a major part of tackling household food waste is availability of composting. However, in Ontario, for example, it’s still not enough to hit the target of a 70% reduction in food waste.
This means green bin programs need to be more rigorous about actually composting food scraps, and ensuring diversion from landfill is high. Part of that responsibility is also at the household level, where consumers need to be sure they’re not contaminating their green bins with un-compostable items. While expanding composting to areas that don’t currently have it is technically positive, better waste management must be ensured overall, so we don’t end up just dumping more food in landfills.
At the food production level—anywhere from farms and factories to restaurants—food waste occurs for many reasons, but largely because there are usually legal or public health parameters that do not allow, or make it difficult to get surplus food to where it’s needed. The dairy industry, for example, is likely to have surplus food during production, but due to regulations around legal expiry dates on products, it’s hard to reuse or give away that food. Grocery stores face a similar conundrum, bound to sell-by dates and the risk of losing customers with misshapen or imperfect produce on shelves.
Unlike healthcare or transportation, some waste does not have to be inevitable when we’re talking about food. By not over-buying and using a green bin properly at home, consumers can eliminate a major chunk of the food waste problem. In our next piece, we’ll discuss current efforts to reduce food waste and their effectiveness.
Sustainable Healthcare: Reducing Waste in the Medical Sector
Every industry faces unique issues when it comes to reducing waste. Restaurants are grappling with the switch to sustainable takeout packaging, while the textiles world is responding to the challenge of scaling down from fast fashion. Healthcare is no exception, and it’s a sector that comes with distinct challenges.
Healthcare settings generate a significant amount of waste. A 2019 report on 110 Canadian hospitals found they generated nearly 87,000 tonnes of waste annually, about the size of the Great Pacific Garbage Patch – and this doesn’t include waste from long-term care homes, clinics, or private practices.
A main driver of this waste are single-use items, which are common and necessary in healthcare. Things like gloves, cotton swabs, syringes, and bandages are single-use, and for good reason – to protect and promote patient health. Indeed, the Canadian government’s recent single-use plastics ban included exemptions for healthcare.
Another factor specific to healthcare is the delineation of the waste stream, between “regular” and biohazardous waste. The World Health Organization (WHO) estimates that about 85% of waste produced in healthcare settings is non-hazardous and can be disposed of the same as household garbage. The rest must be treated as hazardous, including things like used syringes, human waste, vaccine products or medications. Though there’s a clear delineation of the waste streams, contamination continues to be a problem.
The Canadian Medical Association Journal published a review of waste issues in the country’s healthcare system, and improper disposal was named as a major one. According to Laurette Geldenhuys of the Canadian Association of Physicians for the Environment (CAPE), much of the garbage produced in healthcare is improperly discarded with hazardous waste. It is then either unnecessarily incinerated or sanitized, adding both cost and greenhouse gas emissions.
Geldenhuys noted that many physicians are confused about how to properly dispose of waste, and in an intense, high-stress job, this can fall to the wayside. She tackled the problem in her own lab by conducting an audit, bringing in additional bins and bags for recycling and garbage, and educating staff. In just one month, the lab’s special waste output was reduced by 75%.
While this proves that better waste management is possible, there’s also a need for more sustainable products in healthcare, especially single-use items.
5REDO is currently working on a prototype for compostable gloves, as these are some of the most common items to end up in landfill and are otherwise not reusable. The same goes for things like cotton swabs, packaging, or wound dressing. There are reusable or compostable versions of these on the market, and phasing them into healthcare – while ensuring patient health – could be a crucial step.
Healthcare is essential, and so is the innovation to make it more sustainable. While many sectors are focused on shifting reliance from unsustainable products – like sourcing energy from wind or solar rather than fossil fuels – healthcare isn’t going anywhere. Instead, it must adapt, as it has for centuries, to best practices for both patients and the planet.
