During a recent Driving Sustainable Change class, we implemented the methods of Design Thinking to try to answer the difficult question, “How might we reduce the consumption of single-use products at UVM?”

This is a question I have tried to answer for myself on many occasions: How can I change my behavior so that I can reduce my consumption of single-use products? By single-use products I mean any product designed specifically to be used once, then discarded, simply to be replaced by another single-use product.

I used to believe that as long as I recycled the plastic I was using, I was doing my part. However, I have realized that recycling is not enough. There is a reason why the phrase goes reduce, reuse, and recycle. Reducing and reusing come before recycling because that is how to make the most positive impact.

Recycling is better than not recycling, don’t get me wrong, but the current recycling process has many inefficiencies. First, containers must be clean of contaminants. In a full bin of recycling, items that are not recyclable — contamination — weaken the marketability of that material, and those items wind up in a landfill anyway. If the plastic does end up going to a recycling facility, it takes large amounts of energy and resources to transform it into a product that can be used again. Monitoring and collection, transportation, and the recycling manufacturing process itself all contribute to this energy and resource consumption.

The molecular makeup of plastics makes it very difficult for it to be broken down and transformed back to its original product, like a water bottle being turned back into a water bottle. Instead, recycled plastic is usually used for secondary reprocessing which turns the recycled plastic into a plastic product that cannot be recycled. This repurposing of plastic is better than just throwing it in landfills, but its footprint should not be minimized. There must also be demand for the recycled material for this process to really be effective. Many recycling programs are operating at a cash loss on a regular basis, which is not sustainable for the long-term.

So, what is the solution to this? Recycling used to be seen as the solution for all of our waste. But, that is just not enough if we plan on saving the planet. The real solution is to not create the need to recycle in the first place. Reduce your consumption of single-use plastics, or better yet, don’t use single-use plastic at all. Nobody is perfect, so if you do buy plastic try to reuse the item as many times as you can. Get creative with it! How many new uses can you get out of a plastic product? But, since the goal of this post is to reduce the consumption of single-use products, I am going to leave you with some tips that have helped me.

1. The Grocery Store: Single-use products are everywhere here, from lettuce wrapped in plastic, to eggs in plastic casings, to meat packed in plastic bags. Become mindful of your purchases at the grocery store. Start your grocery shopping the right way by remembering to bring your own shopping bags- this will set you up for a successful grocery shopping trip right from the start! Put your produce in these reusable bags instead of putting them into the small plastic produce bags and try to buy produce that is not already wrapped in plastic. Choose cardboard over plastic whenever possible. Cardboard is generally easier to recycle and tends to biodegrade more easily. So go for the eggs in the cardboard casing, or the pasta in a box instead of in a bag, or detergent in a box instead of a bottle.
2. The Bathroom: Look in your shower and count how many plastic containers are in there. Is there a way you can change your purchasing behavior to find products that don’t come in plastic? Can you refill glass containers with shampoo, conditioner, and body wash? There are companies, like Lush, that are selling solid shampoos and body washes that do not have to be contained in a bottle at all. Instead of buying disposable razors, try switching to a razor that lets you replace the blade or, even better, get a straight razor. Instead of shaving cream, try coconut oil. And if you really want to commit to a sustainable shaving experience, don’t shave at all! There are many alternatives to your plastic toothbrush, as well. Try going with a wooden toothbrush, one that you can just throw in the fire when it is time to get a new one. While we are on the topic of teeth, have you ever tried tooth powder? You can make your own at home with baking powder, salt, and essential oils for flavoring. You can also buy pre-made tooth powder from brands like Uncle Harry or Aquarian Bath.
3. The Kitchen: Plastic has inundated our kitchens in the form of plastic baggies, plastic wrap, and plastic storage containers. Instead of using plastic wrap, use jars or glass containers. There are also some innovative companies, like Bee’s Wrap, that are coming out with reusable food storage solutions. Instead of plastic baggies or plastic containers, why not use a glass or stainless steel bento box? If you’re feeling extra brave, bring these out with you when you know there will be leftovers. Instead of relying on a restaurant to provide you with a single-use container to-go, complete with a plastic bag, opt to put the food in your own container that can be reused over and over again. Try switching to wash cloths instead of paper towels. Paper towels come wrapped in plastic and can only be used to clean up one mess. Wash cloths can be used over and over again and just get thrown in with the rest of the dirty laundry when they need to be washed.

What happened to that plastic bottle you threw in the recycling? Do you really have to rinse out that milk jug before putting it into the recycling? A little left-over yogurt doesn’t make a difference? Can you recycle plastic bags?

If you are like a lot of people you probably don’t, and you hope or wish that the items you put in the bin get recycled. But this “wishcycling” can actually do more harm than just throwing contaminated or non-recyclable items away. On a recent site visit to Casella Waste Systems‘ Charlestown recycling facility in Massachusetts, I learned a lot about what happens to products after they go into the blue bin.

At the recycling facility we visited, contamination was visible throughout our entire tour. Film plastic bags clogged the machines, small items fell through the cracks, and foreign metal objects damaged equipment. All of these items are not allowed in the zero sort recycling bins, but still manage to find their way in and wreak havoc.

During our tour of the recycling facility we learned more about the challenges that recycling facilities face. One of the major challenges is food contamination in the recycling stream. This can range from unwashed containers to cans still full of food. This has a massive impact on a recycling facility because items are sorted using all sorts of gadgets. To sort plastics the facility uses optic readers that read the type of plastic and send out puff of air to sort plastic. Other parts of the facility use things like magnets to sort material. Because so much of this system is automated and is carefully calibrated to deal with clean materials contaminated items don’t make it through the system.

When non-recyclable items don’t make it through the system they are sent to the landfill or to an incinerator. This includes all of those small plastics, random pieces of metal, plastic bags, and more. This is why it is really important to check with your local recycler to see what products they take in the blue bin and which have special instructions.

The trouble with recycling doesn’t stop at the facility though. The bundles produced by recycling facilities still have some level of contamination. The largest buyer of recycling was China, but they have closed their doors to recycling with contamination levels above 0.5%, which is beyond the technological capability of any recycling facility today.
