Plastic waste threatens our oceans!

Water covers 72% of the earth's surface and is our main source of oxygen. This plastic pollution can seriously damage our health. The vast majority of pollution comes from our land.

Our mission

Reducing the plastic waste in oceans and rivers.

Our vision

We all know that plastic waste is bad for the environment, but only awareness isn’t enough. Stiksoep thinks that people are more willing to act if they are actively involved. That’s the reason why we don’t only educate, but also work in a creative and artful way with plastic waste.

Our goal

Take care that there will be less waste in the environment and that the plastic soup in the oceans will not increase. To support initiatives, which are looking for solutions to clean the oceans. Using the power of art to help with this social problem.

Our inspiration

An important initiative is the one from Charles Moore, he is the founder of the “Agalita Marine Research Foundation". He is the captain of the research ship, ”the Alguita”. Charles Moore has “discovered“ the plastic soup and brought it to the attention. His organization is searching for solutions for this problem and provides education.

Countering the plastic waste problem.

What is plastic soup?

It's impossible to imagine our world without plastics. Numerous utensils and containers are made of it. Much of that is plastic litter. We just throw it away and much disappears into our rivers and ultimately the oceans. But it does not really disappear.

In 1997, the oceanographer Charles Moore while sailing the Pacific, discovered plastic waste dumps in the middle of the ocean. He called this the 'plastic soup'.

Then there were more of these floating garbage dumps with plastic waste discovered: four dumpsites in the Pacific, three in the Atlantic and the Indian Ocean. The eight landfills together are twice as large as the surface area of ​​the United States of America.

The plastic waste in the oceans disintegrates into tiny particles of floating plastic and seems very similar to plankton.

The plastic soup shows that plastic waste never really disappears comes back to us like a boomerang.

Birds, fish and other marine animals eat it and the plastic end up in their stomachs. The result: internal blockages, dehydration, starvation and possible death. In samples taken in 2001 the concentration of plastic particles in the "plastic soup" was even greater than the concentration of plankton.

These poisonous marine animals end up in our food chain. There is concern for potential human health effects of toxic chemicals such as PCBs and DDTs in polluted plastic fish that we get on our plates.

The plastic soup shows that plastic waste never really disappears comes back to us like a boomerang. We now need to do two things: ensuring that minimize plastic litter comes and investigate how the existing plastic soup can be cleared. That puts Stitch Soup occur in.

I, Anita Waltman, love the sea. I swam, dived and also sailed the seas with the Clipper Stad Amsterdam. A few years ago I heard about the ‘Plastic Soup’. At that moment I was studying autonomous art at the Art Academy, St Joost in Den Bosch. From this moment on this incredible story was my inspiration for my further study. Today I am graduated and decided to start de STIKSOEP foundation.

Stiksoep wants to get the attention from as many people as possible. We are convinced that when you tackle this issue in a creative way the awareness will increase. We all use plastic , but can it be a little less. What are we doing with the plastic waste? How can we prevent that it ends up in the rivers and the oceans?

The plastic Soup problem has become so big that governments can’t solve it on their own. Moreover because the oceans are from everybody and nobody governments haven’t been able to solve this plastic garbage problem successfully.

For this reason we have to do something about it ourselves…

Stiksoep hopes that society will take its own responsibility and that everyone will be aware of the consequences of just throwing plastic away into the environment. It helps if we recycle and buy less plastic.

Marcella runs her own company E-mago BV. Her core business is designing corporate identities. As a volunteer she would like to help Stiksoep Foundation to clean the oceans.

The vast majority of this pollution comes from our land.


Stiksoep is constantly looking for sponsors who besides supporting us financially, also have a warm heart for nature.

With your money we support good quality projects , projects that are searching for solutions to clean the oceans. For example the promising projects of Charles Moore, the discoverer of the Plastic soup.


In order to keep the costs down we work mainly with volunteers, but we need a budget to initiate one another. This budget will be minimal , we strive it to be substantially lower than 10 percent of the costs, which is the pursuit of the ANBI.

Stiksoep is an idealistic non-profit foundation.

We start our Program with the youngest children of the Primary School. Small children can easily learn good habits, which is better than unlearn bad behavior.

The education starts with an easy to understand video about the Plastic Soup. Afterwards we will talk about the Plastic Soup and the children will have the opportunity to ask questions.

Than we relate Plastic Soup with art. Why? Because when the problem becomes visual the children will get more feeling with it and they will better experience the problem. At the school will be an exhibition of various artworks made by an artist.


The next step is that the children create their own art of plastic litter. Therefore they have to look for craft material. Especially litter, which they can find outside. Looking for litter will make them aware of the problem and they can solve it themselves by cleaning their own environment. The children will be accompanied by an artist during the crafting. At the end of the week there will be an exhibition and an sometimes an auction. The proceeds of the auction will be for the foundation.

Another activity for the children is collecting plastic bottles in their neighbourhood to get more people involved. Not only the children at school , but also neighbours, brothers, sisters, parents, grandparents and friends. The deposit will be collected for the foundation Stiksoep.

The main goal of the School Program is the involvement with the plastic litter problem. The second goal is collecting money for the Foundation and others.
