The Trashbin Challenge can be undertaken any time you want.
We recommend that you plan your challenge out so that you are prepared with somewhere to store your collected plastic.
Pick a date and then make sure you are ready when that date comes.
You need to keep all plastics that would normally be produced by your household / school / workplace / etc
This includes any and all kinds of plastics such as soft plastic wrappers, cling wrap, plastic food trays, polystyrene containers, sweet wrappers, detergent bottles, broken toys, makeup containers, drinks bottles etc.
If it is made of plastic and you would normally throw it in your refuse or recycling bin then wash it, and keep it.
We recommend taking a look at the challenge guidelines for a step-by-step outline of how to take part in the challenge.
To share your progress photos with us you can either post them directly to our Facebook Community page or use the hashtag #trashbinchallenge on Instagram and Twitter.
We recommend that you Tag / Title your photos 'Week 1', 'Week 2' etc. You can also include the plastics footprint result as well if you like.
If you have some great ideas for reducing plastics usage, recycling or other plastics reducing initiatives then please feel free to share them on our Facebook page or tag us.
Calculating your plastics footprint is easy using out footprint calculator. All you need to do is enter the type and quantity of plastics that you collected during your challenge, the number of people in your household, the period of time you collected over and the calculator will then generate your plastic footprint for you.
If you don't want to type in all of your individual items, you can also use the following formula to calculate your plastics footprint.
Your Plastics Footprint = (Number-of-items-collected / (Number-of-people + Number-of-days)) x 365;
You might ask why do we calculate the plastics footprint this way, why don't we differentiate between items? surely some items are larger / heavier than others!
The simple answer is that we consider that ALL plastic items have the potential to do harm to animals and the environment, so they are all equally as bad. We also want to keep the challenge simple for people to be able to undertake and having to keep track and type in a bunch of different items just makes it too hard. Counting all individual items of plastic is simply the easiest way to keep tally. It also means that you can use the simple formula above if you wish.
The standard length of time for undertaking the Trashbin Challenge is four weeks, which is approximately one month, but you can make your challenge last as long as you want. We recommend doing the challenge for at least one week to really get an idea of how much plastic you consume.
If you are undertaking your challenge in a location where you expect to collect a non-typical volume of plastic you can also alter the length of duration to suit.
