What you need to know about the lifecycle of plastic

The Climate Change Collective is an initiative where the blogging community unites behind a common goal. As Plastic Free July wraps up for another year, this month’s lead post is from Alison at A Sustainably Simple Life, who provides an informative look at the lifecycle of plastic and why it’s a problem for the environment.

Exploring the lifecycle of plastic

One of the reasons humans love plastic is its durability. But that durability is also its biggest problem. It never goes away. Whether we use it for a few seconds or a few years, plastic stays on the planet for hundreds of years after we dispose of it.

In this month’s Climate Change Collective lead post, Alison from A Sustainably Simple Life takes a comprehensive look at the lifecycle of plastic and the ways it hurts the environment. Starting with the extraction of raw materials, through to production, manufacturing, distribution, usage, and disposal, the potential for damage throughout the lifecycle is great.

Being a mindful plastic consumer

Along my journey to sustainability, I’ve learned that it is virtually impossible to eliminate plastic from my life. However, I’ve also learned to be more mindful about my use of plastic.

Being mindful starts with considering the utility of a plastic item and asking myself a few questions.

  • How long will I use this item for?
  • Why do I need it?
  • Is there a packaging-free option?
  • Can I buy this product at a bulk store or refillery using my own container?
  • Can I reuse the item?
  • Is it recyclable?

The first questions get to the heart of the plastic problem. Our desire for convenience means we use many items for a few seconds or minutes and then throw them away—things like plastic water bottles, single-use beverage containers, and plastic shopping bags.

Beyond single-use to packaging-free and durable

In my opinion, the only valid single-use plastics are sterile items used in the medical field. Every other single-use plastic item can, and should, be eliminated and replaced with packaging-free, reusable or durable alternatives.

Replacing single-use shopping bags with reusable bags is one of the simplest swaps, and there has been a definite change in consumer behaviour in this area. But what’s disguised as progress isn’t always a better alternative. As an example, during a recent trip to California I noticed the “reusable” shopping bags sold in supermarkets are just heavier plastic versions of the single-use plastic bags that have been banned in many areas. I had to wonder how many of those bags actually get reused, and how many just get tossed in the trash, causing more harm than good.

There is no such thing as away. When you throw something away, it must go somewhere

At the opposite end of the spectrum are truly durable goods made from plastic. When we replaced our deck and reinvented our outdoor space last year, we invested in new patio furniture made from recycled plastic. It’s sturdy, durable, and I expect it will be the last patio furniture we ever buy.

Learning and knowledge is one of our biggest weapons against climate change. Please take a few minutes to read Alison’s post.

The end of a piece of plastic’s life cycle isn’t the full story of plastic’s damage to our planet; there is a lot more to the creation, distribution, and use of plastic.

About the Climate Change Collective

The Climate Change Collective was born out of an exchange that took place when I left a comment on a blog post by Jamie Ad Stories. Jamie and I wanted to find a way to keep the climate change message top of mind for everyone, so I put out a tweet to see what kind of interest there would be in a climate-change-related blogging collaboration. The Climate Change Collective was born!

The members of the collective take turns writing a monthly blog post sharing their unique perspective about climate change. After the post is published, the rest of the group keeps the conversation going by sharing a link to the post on their blogs along with their thoughts and ideas.

If you’re a like-minded blogger and would like to join our collective, please get in touch. More voices joining the conversation means more attention to the problems plaguing our planet!

Thanks to Alison for being part of our Climate Change Collective and for providing insights into the lifecycle of plastic.

What steps have you taken to reduce your single-use plastic use? Tell me your thoughts below.

Hi there! I’m Michelle and I live in Kitchener, Ontario, Canada. I am married with two young adult daughters. I’m a big fan of reducing waste, using less plastic, decluttering and simplifying life as much as possible.

  1. Plastic is a really complicated construct. We use it too much but they still need to work on some alternatives. I make sure I use paper straws but often find that half way through the drink they go soggy and I can no longer suck up the drink (this happened in the cinema recently).
    I hope they pump money into finding good sustainable alternatives and soon. I will use them.

    1. I agree Jamie. There are alternatives to plastic but some need to be perfected. I rarely use a straw but I find our paper straws here are pretty good. I was so shocked in the United States recently that plastic straws…and plastic cutlery…are EVERYWHERE! I have to remember to say “no straw” when ordering a drink and I always forget.

I'd love to hear your ideas. Drop me a comment below.
