Products, waste and emissions

A number of waste flows are produced in Leiden University buildings. These are collected and removed as much as possible separately.

Waste should be collected and removed separately as long as this is economically viable. Dangerous waste (chemicals, radio-active waste) must always be collected and removed separately.

Waste prevention and purchasing

One of the ways of reducing waste is to ensure intelligent and sustainable purchasing of products. For this reason, the environmental impact of products plays an important role in the European tenders.

What can you do?

As an employee or student, you can also contribute to reducing the waste flows. A few tips: 

  • Throw away old paper and cardboard in a paper container; this saves money.
  • Print and copy documents only if this is absolutely necessary.
  • Write, print and copy everything double-sided.  
  • Use the notice board or the personnel newsletter to make announcements. Not everyone needs to receive an announcement on paper.  
  • Do not use any disposable products.
  • Buy longer-lasting supplies.
