Better waste separation at the university

Published: 16 November 2015

Akademiska Hus and Luleå University of Technology have launched a joint initiative to make the campus in Luleå more sustainable. Through improved sorting one wants to reduce waste and increase recycling which contributes to sustainable development.

In recent years the number of students and staff increased on the university campus in Luleå. The premises are extensively used and also increasingly on evenings and weekends. More people want to be on campus during more hours of the day is seen as something very positive. It also means increasing amounts of waste to deal with because there will always be waste of human habitation.

Right now a pick analysis is carried out by the research group Waste Technology, with the help of students at Luleå University of Technology which runs programs MSc Natural Resources Engineering and Industrial environmental and process technology. Combustible waste from two garbage sorting is scrutinized. According to the regulation on producers responsability all packaging waste should be sorted for recycling.

- Plock analysis shows that a large part of the packaging ends up as combustible waste resulting unnecessary costs and lost recovery potential. The same goes for food waste to be sorted and collected for the anaerobic digestion or composting, says Lisa Dahlén researchers in waste technology at Luleå University of Technology.

The result of the picking  study will guide Akademiska Hus and Luleå University of Technology how education and information initiatives should be targeted. The analysis will also provide answers to how future garbage sorting should be designed to be able to sort as well as possible and so improve and increase recycling.

For both the environment and everyone's comfort future investments are made in improved waste room. Also an information input in how to sort waste must be made, and connected to that Akademiska hus and the university hope that it should lead to improved waste management and increased recycling.
