The university's waste policy is aimed at preventing waste. Where waste does arise, we try to separate it as much as possible and dispose of it properly, safely and responsibly.
At the University of Twente, we are trying to collect more and more waste streams separately. Since the end of 2017, we have been creating waste islands at central locations in our buildings, enabling us to further separate waste in and around offices and teaching rooms. There are 4 waste streams:
- PMB (plastic, metal and beverage containers), with several islands also featuring a separate bin for coffee cups.
- Fruit & Vegetable waste
- Residual waste.
The buildings are also equipped with bins for large pieces of cardboard, glass containers and confidential paper containers. Though slightly less visible, the following streams are also collected separately at various locations:
- Coffee grounds
- Swill (food waste from catering locations)
- Laboratory glass
- Bulk waste
- Electronic waste
There are special procedures for the disposal of hazardous waste (mostly chemicals). For more information on which procedures to follow, please contact the HSE coordinator of the faculty or service in question.

The graph above shows the amount of waste disposed by UT in recent years. For more information, please visit this page with facts and figures.
From 2017, all UT waste is collected by SUEZ. As a result, the breakdown into waste categories changed somewhat, which means the quantities after this date cannot be compared directly to the quantities in previous year. To find out more about when waste is collected, please see the ‘waste materials’ section in the products and services catalogue.
Proper waste separation reduces the amount of residual waste and makes it easier to recycle.
- Paper: newspapers, printer paper, cardboard, envelopes, books
- PMB (plastic packaging, metal (cans), and drink cartons): plastic bottles, cans, drink cartons, foil
- Organic waste (biodegradable waste): all biodegradable waste (excluding packaging material)
- Residual waste: crisp bags, pens, napkins, polystyrene
You can use the waste separation guide developed by Milieucentraal (Dutch only) to find out how to separate your waste properly and which waste product belongs to which waste stream.
Paper is sorted, pressed into large bales and transported to the paper mill, where the sheets of paper are turned into paper pulp. After the ink has been removed, the fibres are used to make new paper.
Food waste and fruit waste are processed into compost or used for the production of biogas.
All plastic waste, trays, cans and cartons are sorted extensively, after which they can be reused to make new products, such as packaging, watering cans or furniture.
In the Netherlands, residual waste is incinerated, which generates that that is converted into energy. This is the energy that is used to heat most of UT’s buildings. Waste that cannot be incinerated is often used in road construction.
Students living on campus can hand in their separated PBM waste in the municipal orange container behind the Bastille. Glass containers can be found scattered all over campus (Calslaan oud, Campuslaan (Matenweg), Witbreksweg and behind Bastille). There are also white containers for clothing and textile behind Bastille and waste paper is collected in crates.
At student housing, waste is collected in block containers. In time, these will be replaced by several centrally located waste collection stations with underground containers for paper, PMB, glass and residual waste. Twente Milieu is currently conducting a trial for the collection of fruit & vegetable waste and we want to make use of their experience when making a decision on how to collect fruit & vegetable waste at student housing.
- Prevent waste. Drink tap water instead of bottled water
- Buy products with minimal packaging. Buy your fruit and vegetables unpackaged at the market.
- Reuse products or look for reusable alternatives
- Compost biodegradable waste (kitchen waste)
- If you’re still left with waste, dispose of it in the correct waste bin. If the waste is separated properly, it’s easier to recycle.
