How consumers can help climate change by changing their plastic habits

As bushfires continue in Australia, consumers can make a difference for the future.

As much of the east coast of Australia continues to put out bushfires, my hometown of Canberra has been suffering with the worst air quality in the world.

Since September when the first bushfires began for the season, the country has suffered. And since November, I’ve begun each morning by first checking the air quality and then the Fires Near Me app.

So far, we have been the lucky ones in Canberra to only have to deal with smoke. Others have lost much more than clean air. Eventually, when these bushfire threats have passed, we’ll think more about the future including what we can do to ensure it doesn’t happen again.

Yet, it’s hard to think about prevention solutions without considering the impacts of climate change. While we may feel powerless as individuals until the next election, as consumers we actually have a lot more power collectively than we realise to create change.

Over the last few months, I have been interviewing entrepreneurs on my podcast, Plastics Revolution. These change makers are using business solutions to tackle the plastic waste issue both by providing options to reduce plastic consumption, as well as to recycle it into products afterwards. Time after time, they’ve reminded me about the power of the consumer dollar in creating change.

While much has been said recently about the environmental impacts of plastic waste, there’s actually a lot of information out there about the carbon footprint of creating it in the first place too. And here lies both an opportunity and a responsibility for those that want to avoid future weather disasters such as the one we are experiencing in Australia right now.

Let’s have a refresher about climate change before I explain this consumer power further.

Climate Change 101

While climate change may be a controversial topic for some, most will agree that “normal” weather is changing.

NASA has well-documented the facts and evidence of climate change here. The most simple explanation regarding these changing weather patterns is that carbon dioxide and other gases in the atmosphere trap heat which increases the earth’s average temperature. Amongst other methods, this increase has been documented from ice core extractions in Antarctica, Greenland and various glaciers.

In an article written by Robert Walker, he warned that Australia could be the canary in the climate change coal mine. Multiple years of drought has made Australia even more susceptible to bushfires during this record-breaking summer heat which is expected for future years to come.

Here and in other countries like the US, it’s tough both politically and economically when your country’s greatest natural assets are also the biggest contributors to creating CO2 – namely the burning of hydrocarbon fuels like coal, natural gas and oil.

Every economy’s vitality is based on growth i.e. the increased selling of its goods and services. Unfortunately, that measurement is traditionally done only with dollars by both businesses and governments alike. This model simply fails to look at the whole of life costs including the impacts to the environment after a purchase is made.

In fact, there can be false measurements of an economy’s strength after a natural disaster. Government relief will often stimulate a location as people rebuild their homes and businesses thereby creating new jobs. On paper, it can actually make an economy look stronger than before the disaster. And yet, a chat with locals will showcase the flaws in the numbers.

Furthermore, measuring prosperity this way does little to incentivise emissions-causing businesses to change their traditional processes when it could hurt their bottom line. That’s where the consumer has the potential to play a much larger part.

So how does this relate to the use of plastic?

Plastics are made of petrochemicals i.e. oil or natural gas, and the process to extract it from the ground, transport it, and turn it into its common resin form takes a lot of energy by burning more petrochemicals.

Traditional Manufacturing Process for Plastic

Looking at this traditional process objectively, the only reason why a business would go to so much trouble is if there are profits to be gained.

A recent study by The Center for International Environmental Law analysed planned expansions of oil and gas infrastructure around the world. It predicts from 2020 to 2024, oil and gas companies are set to invest a further US$1.4 trillion in new oil and gas extraction projects.” However, even without these expansions, they don’t believe that current operations will enable the Paris Agreement goal to keep global warming below 1.5 degrees Celsius.

Once again from a business perspective, these investments would not be made if it were not for the potential for profit that’s driven largely from forecasted consumer demand.

While most people think of mining, electricity plants and transportation as the emitters of C02, one article concludes that the full cycle plastics industry creates “almost double the emissions of the aviation sector.” And this only includes plastic products made from extruded pellets, not textiles that are also made from plastics which I’ll discuss later.

How is this possible? The chart below shows the primary uses for plastic. In most of these categories, they are directly link to the average consumer’s buying habits.

Uses of Plastic

How much energy does it take to make a plastic water bottle?

If we break down these categories to something more tangible, it shows the kind of difference that an individual could make with small decisions.   For example, in the creation of packaging specifically, an study about the making of single-use, PET water bottles found that:

“Producing bottled water requires between 5.6 and 10.2 million joules of energy per litre, depending on transportation factors. That’s up to 2,000 times the energy required to produce tap water.”

Gleick, P.H. and Cooley, H.S. “Energy implications of bottled water.” Environmental Research Letters 4 (2009) 014009 (6pp).

If enough consumers moved away from bottled water, this would have a measurable impact to the emissions generated in creating the plastic in the first place.

What about our clothes buying habits?

It’s not just with food packaging where consumers can make a massive difference though. It’s also in the clothes that we wear too.

According to the UN Environment Programme:

“The fashion industry produces 10 per cent of global carbon emissions.

Given that any man-made materials such as polyester are also derived from petrochemicals, it easy to see why this statistic is so high. This is especially true with the fast fashion trend that’s created the equivalent of “single-use clothing.”

5 Ways consumers can help climate change by changing their plastic habits.

With the evidence mounting about climate change, as well as the known issue with plastic waste, it’s time for consumers to really put their buying power to use.  Here are some ways that you help climate change by changing your plastic habits:

1) Buy more products made from recycled plastics

The traditional method for extracting petrochemicals and turning it into products may seem onerous based on my diagram earlier, but the process is actually easier than manufacturing with recycled plastics. This is because there are so many types of plastics produced, and they often are contaminated with food and other things when disposed. This is why recycled plastic products may be more expensive than those made from virgin products (particularly those made in lower wage countries).

Nevertheless, some of the bigger recycled plastic manufacturers in Australia have figured out ways to create products with this material.  Below is the general process that Replas and Plastic Forests use as discussed in previous podcast interviews with their owners.

Notice how their process eliminates the energy required for petrochemical extraction and can reduce overall transportation emissions in comparison to the traditional process.  They create the plastic pellets by shredding and melting the plastic which also requires less energy than making it from scratch.  Some of these companies also reduce their transportation footprints further when they bypass the wholesaler and go direct to the consumer or retailer.

So, how much cleaner is the recycled plastics manufacturing process than the traditional one?

If looking at the full cycle (cradle to grave – where my diagrams only show cradle to consumer), one study found that “recycled PET bottles offer both GHG emissions and fossil fuel consumption reductions ranging 13% to 56%, compared to fossil fuel-derived PET bottles assuming PET bottles are landfilled.”

Another study by the Nordic Council of Ministers reviewed other publications from around the world and concluded that there was a 37% reduction in emissions generated from the production of recycled plastics (all types) compared to their virgin counterparts. It also showed that there was a 55% reduction in emissions when recycling versus incinerating plastics.

Today, there are increasingly more and more products made from recycled plastics.  When given the choice, even if they are bit more expensive, you should buy the recycled option. You’ll help the environment by both reducing the amount of waste that would otherwise go to landfill, as well as reducing the carbon emissions footprint of making the product.

2) Borrow or buy used

Other than potential transportation costs, there really aren’t any carbon emissions generated by an used or borrow item.  The cost was already bore upfront in making it and getting it to the consumer the first time. There will, however, be emissions generated if the item is disposed of instead. So, giving something new life is always a better option for the environment than buying new or throwing it away. 

Today, there are more and more options for previously owned products even if you if you’re not keen on thrift stores.  In Australia, you can rent your wardrobe from GlamCorner, your kids’ toys at Tiny Tots to Hire, and your power tools from Bunnings. If you’re in the US, you’ll have even more options.

Or if you prefer purchasing the product, you can buy second hand even at mainstream retailers like Ikea and The North Face.

The reality is that for many purchases these days, you should always consider a borrowing or second-hand option first if you want to do your part for climate change.

3) Use your non-perishable products longer

Whether it’s clothes, toys or your car, the majority of emissions for any petroleum-based product is generated from the extraction phase to getting it to the consumer.  Therefore, when it comes to concerns for climate change and buying something new, you are much better off buying quality products that will last and stay in style longer.

Furthermore, when it comes to quality, pay attention to the materials it made of as well. For clothing in particular, purchasing natural materials such as cotton and wool will help enormously with reducing demand for petroleum products. And if you must buy something with synthetic fabrics, see if you can find it in recycled materials like polyester made from recycled PET bottles or ocean waste.  There are plenty of great brands doing this now including Adidas and Filippa K.

While this goes against the low-cost/short-lasting mentality that many consumers have, just remember once again that you are voting with your dollars. Businesses will respond accordingly – whether it be the large petrochemical companies, the product manufacturers or the retailers because it’s in their financial interest.

4) Reduce your plastic consumption

We hear about this frequently as governments around the world are instilling bans on single-use plastic.  While the reduction of waste is obvious when you use a reusable coffee cup, bottle, bags, etc – the lifestyle changes also make a difference to C02 emissions as discussed earlier with the water bottle study.

Businesses will only make what consumers are willing to buy, and the flood of reusable containers to the market right now shows that this is catching on by many.

5) Buy Local

Finally, one of the best decisions that consumers can make is to buy locally manufactured products. This may be Australian-made or American-made as an example rather than a cheaper version from overseas.

Transportation can make up a huge percentage of the total carbon emissions generated for plastic products depending on where it is made. So, deciding to buy local is not only good for domestic businesses, it’s also a decision to reduce carbon emissions generated in producing a similar product overseas.

Final words

As long as consumers use their dollars to maintain the status quo, carbon emissions will continue to rise as industry responds to our demand. Yet, our environment can’t handle the increasing changes to temperatures. Without significant changes soon, we’ll continue to see more weather-related disasters like we are experiencing in Australia now.

While businesses and industries (and the governments they support) may not respond to public calls for climate change, it’s been shown time and time again that they will change with consumer demand.  Isn’t it time to collectively vote with our dollars to do something about this before we are impacted even further?

Dear consumer, the power is in your hands!

Experiment #1 – milk bottle lids

Given the crazy cost of creating my products using the old fashion manufacturing method of injection moulding, I decided to experiment with plastic using even older methods, but that would cost me only my time. My raw ingredient? Milk bottle lids.

Instead of coming up with a solution to a problem where recycled plastic can be the main ingredient, I thought I would work backwards and use a known waste plastic and see what I could do with that.

There’s a charity in town that started collecting lids for a company that makes prosthetic limbs for children. However, they are way over capacity now. So, I knew that there were buckets of lids just lying around, and I managed to grab a bucket from my friends over at Local Press. Most of them were milk bottle lids from the local milk company.

This is the experiment I just did to see if I could make a minimum viable product.

Cleaning and sorting milk bottle lids

More work to do, but a truly interesting process in any case to see if I could replicate some of the things I’ve seen online and heard about, but using my own methods to experiment with milk bottle lids as my plastic source.

Introducing the ‘Plastics Revolution’ Podcast

For the last month, and on top of everything else I am trying to do for the business, I have been working on a new podcast called the ‘Plastics Revolution.’

This has been something on my mind for a while as I knew that this work that we are trying to do at The Refoundry was far bigger than just my company.

Plastics Revolution podcast cover with Tammy Ven Dange

A Plastics Manufacturer’s Change of Heart for Recycled Material

Why would an injection moulding plastics manufacturer suddenly decide to change his business strategy in favour of recycled and circular materials? After all, manufacturing with recycled materials is hard. There’s no guarantee for continuity of supply, the quality of feedstock can be inconsistent, processing degrades quality, and there’s always a risk that contamination can impact colour.

In fact, I have met or have been referred to so many amazing people since I started this journey that I felt compelled to share their stories as well. And so, I have embarked on project with no knowledge of equipment or process. Yet, on every step of the way it seems meant to be.

I had a volunteer producer come on board. Interviews have been completed and more are being booked regularly. I’ve also been taking an online course that was starting at the exact same time that I was considering this channel. So the pieces are all falling in place as though it was always a part of the plan.

At this stage, I have no plans to monitise the podcast. Instead, it’s acting as a networking vehicle that is also building my knowledge and credibility in this complex space. I’m not even talking about my own business that much.

Plastics Revolution is a business podcast with an environmental mission. As such, I spend most of the time chatting to innovators, change makers and fellow entrepreneurs who are leading the plastics revolution It’s been fun so far too!

Rather than creating one more website to manage, I decided to add it to my blog here. You can also find the full transcript of this episode there as well.

I hope you enjoy the show and learn a few things too.

America – home of the plastic waste

I’ve been visiting family in mid-Western America this last few days, and it’s a bit of a shock to see so little concern about plastic waste here.

At restaurants, there are already straws in the water glasses before I can say no thanks. Every checkout other than Whole Foods gives out single-use plastic bags without concern. In grocery stores, it’s hard to find anything not meticulously wrapped in plastic packaging. Most every online shopping box that arrives at my brother’s house is full of plastic fillers.

On top of that, I found a just released study from the Environmental Protection Agency from 2015 (not sure why it took them so long) that showed only 9% of plastic is being recycled here in America. This is incredibly scary given that Australia has only 7% of the population of the US, but manages to recycled 32% of plastic. That’s still a lot of plastic going to landfills.

With the strong US petroleum industry and the high cost of recycled plastic, there’s little incentive to change without significant consumer demand. That’s why the solution in America that will likely have the biggest impact will be incinerators like the one being made by Sierra Energy. Their technology is meant turn rubbish to fuel or energy without also creating emissions.

Is this a solution that should also be considered in Australia? It already is.

The question isn’t really about which solution (i.e. reduce, recycle or reuse) because all three will likely be needed to help minimise the impacts of plastic rubbish.

Really it’s about changing people – although the hardest to do. This alone will make the biggest difference of all. And in Australia, based on the stats and my observations, it seems so far that we’re more willing to change than Americans when it comes to helping with this plastic problem.

Will the new Victorian recycling process plant impact us?

When Victoria announced last week the opening of a $20m plastic recycling processing plant, I had quite a few people send me a link to the news article. Surely this must be a great thing?

My quick answer: good for the environment, but I’m not sure yet if they’ll be able to help my need for recycled plastic feedstock.

For those who are unaware of the process of recycling, there’s usually one company (Company A) that collects and sorts the things we place in our household recycle bins.

Then, there’s another company (Company B) that buys these bails of sorted plastic.

Sorted recycled bails

Company B may process it into flakes and/or beads as show below. However up until recently, lots of these bails in Australia were sold to another company (Company C) and exported to Asian countries to be processed.

Plastic flakes and pellets that are the raw stock for making plastic products.

Since many of these countries are no longer taking our plastic rubbish, the bails have lost a lot of value in the after market because there isn’t enough demand in Australia. The most dramatic example is for mixed plastic which dropped from $225/tonne to just $75/tonne the last time I checked.

Therefore, to have another processing plant in Australia is a great thing for this issue as long as there are manufacturers willing to purchase their processed recycled feedstock. Ironically, this is exactly why I started The Refoundry in the first place – to increase demand for Australian recycled plastic.

The articles are not completely clear to me, but looking at the Advanced Circular Polymers website it seems that they are offering various kinds of recycled flakes which larger manufacturers often mix in with virgin plastic to create things like water bottles.

Having the plastic sorted into one kind of plastic like PET rather than mixed plastic is really important if they want to sell it. That’s because each type of plastic has different material properties like flexibility, strength, UV protection and even colour.

At the moment, we ‘re looking for a clear or white coloured HDPE (#2 – think milk jugs), but leaning towards PP (#5 – like ice cream buckets). My manufacturer has existing relationships with other processors that can supply it as long as we don’t go over 10k units a month.

Right now, it looks like the Victorian company is offering both types of feedstock, but I don’t yet know of what quantity or colours (especially for PP) or price.

These are all factors that must be considered when using recycled plastic, but it is definitely good to have more processors in Australia to ensure that less plastic is going into the tip. How this particular company will impact us though needs to be considered further.

How a little bit of plastic can do so much good and bad

Have you ever wondered how plastic products are made? They begin as a petroleum liquid or gas, and are turned into these pellets or microbeads below:

Virgin plastic pellets

I took this picture at one of the manufacturing plants I visited this week. These pieces are about the size of a rice kernel, and the few black ones in this batch will make the whole mix that colour. Because of the size of the beads, they’re easy to melt and then mould into something useful.

Now imagine shipping containers full of these microbeads spilling into the ocean. This is what was found in 2017 on beaches in the UK after that occurred.

The reality is that any plastic product will eventually break back down into these rice size pieces and even smaller over time. Yet, it will be centuries before they can degrade back to petroleum.

This is why there’s so much talk about plastic in the news these days. This is not new knowledge. It’s just that the physical impacts to our environment and wildlife have finally reached such high levels that it’s hard to ignore.

Plastic isn’t a bad product by itself. It’s light, durable, flexible, and lasts forever – the same traits that are also causing harm to Mother Nature. The challenge for product manufacturers is to design their goods for the full cycle of life, not just the making stage.

If everyone thought about the disposal of the product and not just the making and using stages, they would probably make it very differently.

At The Refoundry, we will have a take back system in place where any used product can be sent back to use to be donated for reuse or recycled back into the same product. It will no doubt be expensive do to this with storage and transport costs, but I don’t see how we can consider ourselves an environmental social enterprise and not do this. I can only hope that our customers will value this too.
