Thijs Verheugen was always the first one to sit in the park enjoying some refreshments, weather permitting. ‘Great, but I also noticed that this generated a huge amount of antisocial litter, and it was getting worse every year. I could no longer bear it. Walking through the park it suddenly dawned on me: a picnic blanket on which to lay out your food, and once the picnic is over the blanket becomes a trash bag in one single operation. And that’s it. Ideal because it makes tidying up easier and more fun. It’s the simplest design I could think up together with Twan van Dommelen. A blanket with a hole through which the other three corners are pulled to create a trash bag. Hallelujah! The simpler, the better, and therefore also cheaper!’

‘Trash bag and picnic blanket in one, ever so handy. Best thing in the world!’ – Roos, Vondelpark visitor


The design and the cheerful print are what make the CleanPicnic blanket such a success. The picnic pattern and the high user value make sure that visitors to the park are happy to receive and use the CleanPicnic blanket.

‘We always take along a CleanPicnic blanket in the pram in case we go to a different park for a change, so we’re always prepared.’ – Joke, Sarphatipark visitor


The concept much more than just the blanket. The CleanPicnic blankets are custom-made designs that are given to park visitors by local shopkeepers and park management free of charge. That way everyone helps to keep the backyards of our cities and villages clean.

‘The widespread use of the picnic blankets means that we can reduce the number of men we need for clean-up work by two a day. That saves us 150,000 euros a year.’ – Maurice Veldwachter, district manager at City District West (Westerpark)


Verheugen had the idea in April 2010. In July he received the patent, and in August a test was launched in Vondelpark in collaboration with Nederland Schoon (‘Clean Netherlands’). Peter Vos, park warden at the time, had not told his cleaning crew about the test. The following Monday they asked him where on earth all those trash bags in the waste containers came from. It had worked, and so they were given the green light.

‘It makes people happy. The majority of visitors to Sarphatipark makes good use of the picnic blankets. The minority will follow suit.’ – Riny Meijer, area management consultant for Public Space South (Sarphatipark)


CleanPicnic does not sell blankets but it offers a structural solution for waste problems in parks. The concept’s starting points are:

  • Make cleaning up easier and more fun.
  • Work together with visitors, local residents, neighbourhood shops and the park manager.
  • Make it free for users.
  • The cheerful look of the blankets encourages park visitors to clean up their own trash.
  • Distribute the blankets directly to the picnicking public whenever possible to limit the amount of waste.

‘A sign on the door points to the CleanPicnic blankets this year. I consider it a fixed element of the salad bar.’ – Floris, Westerpark salad bar


If a park has a litter problem and turns to CleanPicnic for help, we’ll gather around the table to discuss this issue at length. Because every park is different and requires an individual approach. Some important questions have been raised, such as: what does the park look like, what kind of visitors does it attract, are hospitality options available, and are there sufficient trash cans in the park? Based on findings, CleanPicnic will present a proposal tailored to the park’s situation. The proposal includes, among other things, the distribution network, the logistics involved in delivering the blankets, the trash bin locations, as well as promotion and publicity.

‘It’s not only sociable and fun, but it’s also good to know that by using these blankets we keep the park clean; so it’s a win-win situation.’ – Paul Laudy, alderman at Public Space Leiden (Van der Werfpark)


CleanPicnic works on the basis of the placemaking concept. This means that as many people as possible will be involved in the solution: park visitors, residents, neighbourhood shops, hospitality/park entrepreneurs, and park management. The solution and the key to success are in the hands of the people themselves and in a good partnership.

‘Normally, we pay handsomely for cleaning work. Nowadays I look around and see practically nothing lying on the grass. Everything disappears in the picnic blankets, and suddenly it’s gone.’ – Bas Schreuder, organiser of Picnic Festival Leiden (Van der Werfpark


In the Vondelpark, CleanPicnic has developed into a successful neighbourhood project that brings together park visitors, local businesses, members of the community and park management. Everyone joins in, contributes and benefits. On summer days this year, visitors can pick up the iconic picnic blanket for their trash at one of 20 grocery shops or hospitality outlets in and around the Vondelpark. The Friends of the Vondelpark association is engaging volunteers to hand out the blankets. The Amsterdam municipality’s park management department replenishes the stocks on summer days to ensure that sufficient trash blankets are always available for park visitors.

‘We believe that by initiating the collaboration between park visitors, neighbourhood residents, local shopkeepers, hospitality outlets and park management we’ve found a positive answer to the Vondelpark’s huge waste problem in recent years.’ – Janine Geysen, Friends of the Vondelpark


We purposely opted for producing the blankets in the Netherlands and not, for example, in China. This enables us to ensure that production is as sustainable as possible in all respects. There are two versions: blankets made of recycled plastic and of plant material, i.e. biobased. The blankets and the production process are in conformity with the Netherlands Commodities Act, which regulates food safety, among other things. This is important because people put their food on the blanket.

‘It was obvious that the corners had to be pulled through the hole, so it serves as a trash bag that you can dispose of. Very handy.’ – Yvonne, Van der Werfpark visitor

Meanwhile, CleanPicnic is helping to clean up parks in Amsterdam, Rotterdam, Dordrecht, The Hague, Groningen, Twente, Delft and Leiden. Consultations are also being held with other cities about the introduction of CleanPicnic, and partnerships have been established with Albert Heijn, ANWB and Mentos, to name a few. And there is a new initiative in the making: the CleanPicnic towel, a towel and trash bag in one, intended to also keep beaches clean. The aim is to launch the CleanPicnic towel in 2018.

CleanPicnic’s mission is to offer a worldwide solution for litter in recreational areas by making cleaning up easy and fun. Much work remains to be done. All help is welcome.

‘I thought right away: that’s something we don’t have in Ghent yet, so we should really launch this in Belgium too.’ – Brecht, Sarphatipark visitor
