PET-Water Free University

During the introduction days 2016, the Green Office VU started the ‘PET-water free University 2018’ project. Together with Dopper, we strive to make the Vrije Universiteit Amsterdam the first PET-water free university of the Netherlands.

At the start of the academic year we participated in the Sustainable Introduction Stunt (NL: Duurzame Introductie Stunt/DIS), a competition organized by Studenten voor Morgen in which study- and student associations compete for the most sustainable introduction stunt and we won! In our Sustainable Introduction Stunt students could trade their PET-bottles for a sustainable Dopper-bottle alternative! In return they could transform their old PET bottle into a small garden, which ended up in a vertical garden. The Green Living Lab helped us out with the garden construction.
The message of the stunt was to create awareness about the impact of PET-bottles on the environment. We want to inspire the VU-Community to start using alternatives. Vice-president Marjolein Jansen of the Executive Board: ‘The quality of tap water is great in the Netherlands, and we need to be apprehensive about our water consumption. The plastic needed to create water bottles puts not only a threat on healthy and potable water, but also on the flora and fauna on land and in the sea. Decreasing the amount of PET used is something we can achieve together. VU means looking further; let’s also look further in this case, and consciously think about the choices we make’.
Dopper embraces our ambition of a PET-water free university in 2018. On a world-wide scale, they combat single-use plastic. Restricting the use of this material at universities forms an important point in this battle. We’re happy to have Dopper on board in our combat against PET-water bottles!

To keep it short, the production of PET…

  • uses a lot of oil;
  • emits tons of carbon dioxide (CO2) via production as well as transportation;
  • creates tons of waste and consequently PET litters everywhere;
  • kills the inhabitants of the ocean;
  • ends up in our bodies as it moves up the foodchain.

To kick-off the ‘2018: PET-water free University’ campaign we aligned it with the DIS stunt-competition. The team was brainstorming about a creative and interactive way of informing students about the downsides of using PET, and we got inspired by the artwork ‘The World of Litter’ by Peter Smith. We sat down together with the Green Living Lab team to brainstorm about possibilities, and inspired by their green surroundings they came up with the idea of a vertical garden. We loved this idea and decided to go with it.
FYI: this does not mean that we want to promote buying plastic bottles to make a garden. We want promote that we should stop wasting plastic.
The Green Office VU decided to team up with Dopper because…
we support their mission. Dopper’s mission is ‘to achieve a world in which people are conscious of the environment we live in, where the amount of single-use plastic is reduced and where everyone, near and far, has access to safe drinking water’;
they are a social enterprise: their primary goal isn’t profit, but a positive impact for a better world;
they received the first cradle to cradle certificate for bottles. Doppers are produced in the Netherlands, there are no toxins used in the bottle, damaged Dopper parts can be returned for free to recycle, and if you break a component it can even be fixed!

There are two main reasons not to reuse your PET-water bottle:
Even if you use your PET-water bottle multiple times, chances are very big that it ends up in nature. Just 5% of plastics are recycled effectively, whilst 40% ends up in landfill and a third in fragile ecosystems (The Guardian, 2016).
Commercial bottled water manufacturers don’t recommend that consumers reuse their disposable bottles, because “everyday wear and tear from repeated washings and reuse can lead to physical breakdown of the plastic, such as visible thinning or cracks. Bacteria can harbor in the cracks, posing a health risk” (The Huffington Post, 2014).
First things first! Water runs through the tap and is easily available without using PET-bottles. If you want to drink a coke, it already becomes a little bit more difficult. In the long run, the ideal situation would be a completely PET-free university, but our first goal will be banning PET-water.
Definitely! There are a couple of dozen universities that pledged for a water bottle free university. Most of them are found in the USA or Canada. For an elaborate overview of these universities, check out
Some European universities are also working on it, such as Sheffield in the UK. Let’s continue this movement in the Netherlands!

Waste doesn’t need to be wasted! By recycling, repairing and re-using stuff that would otherwise end up in your trash can, we can make a great positive impact on the environment. The Green Office VU invites you to waste LESS and introduce yourself to a next level sustainable lifestyle. Waste is one of the biggest factors that have a negative impact on the natural environment since harmful chemicals and greenhouse gasses are released from its processing. The Green Office VU would like to ask you to participate in our WasteLESS campaign by consciously separating your waste, and reduce your waste production by using re-using and recycling.
Stay tuned for more information on this web page on how to reduce your waste.

Meatless Monday


Meatless Monday at the Vrije Universiteit Amsterdam
Every Monday, Sodexo will provide us with more vegetarian options and less meat options to show us easy vegetarian substitutes for meat. Meatless Monday is a part of the Better Tomorrow plan of Sodexo. Via this campaign we hope to raise awareness on the disadvantages meat consumptions brings. Check the information below to find out yourself why it’s good to reduce your meat consumption.
Did you know that..
• the meat industry is responsible for about 1/5th of all the greenhouse gasses?
• a lot of trees are being cut to grow food for the livestock and that 80% of all the land in the world is being used for livestock?
• the production of meat costs more water and energy than the production of wheat and vegetables?
• we need around 25 kg of food and 15.000 liters water for just 1 kg of beef?
• the world population has doubles in the last 50 years whilst the production of meat has grown 5 times bigger?
• we can plant 83 million trees and let them grow for ten years if all people in the Netherlands would join us with the Meatless Monday?
By going meatless on Mondays, we join the global movement of Meatless Monday. Next to the benefits mentioned above, the key benefits of joining this movement, as outlined by the international campaign of Meatless Monday (2011), are as follows:
