Waste Fractions and Recycling Methods

AAU sorts its waste into several fractions, including residual waste, organic waste, paper, plastic, and hazardous materials. Residual waste is recycled through incineration, contributing to the Danish heating system by producing heat. Organic waste, totaling 32,916 kg in 2023, is converted into energy, either as fertilizer or heat. This amount of energy could provide heating for a household for 1,300 days or produce fertilizer for 53 tons of carrots.

Carbon Neutrality

AAU’s waste management system is designed to be carbon neutral. The energy extracted from bio-waste offsets the CO2 emissions from the remaining waste, ensuring that the university’s waste disposal processes do not contribute to net carbon emissions.

Climate Plan Goals

As part of its climate plan, AAU aims to reduce the total amount of waste by 30% from 2022 to 2030. This ambitious goal underscores the university’s commitment to sustainability and environmental responsibility.

Monitoring and Measurement

AAU measures waste quantities at all locations across the entire university. This comprehensive monitoring helps in setting accurate reduction targets and tracking progress effectively.

Student and Staff Engagement

The success of AAU’s waste sorting program is also attributed to the active participation of students and staff. Educational campaigns and clear guidelines have been implemented to ensure everyone at the university is informed and engaged in proper waste sorting practices.

Future Goals

AAU continues to strive for further improvements in waste management. The university aims to increase recycling rates and reduce overall waste production, contributing to a more sustainable future.
