Aalborg

In Aalborg, the municipality has chosen to invest in optical sorting to simplify source separation for residents while also creating a more sustainable waste management system.

The solution is operated by the private company Meldgaard Miljø A/S, on behalf of the municipal company Nordværk, which is owned by Aalborg Municipality.

The facility handles approximately 42,500 tonnes of waste per year from the city’s 110,000 households and 5,000 holiday homes, where around 224,000 residents now sort their waste into coloured bags.

Initially, two fractions are included: food waste in green bags and residual waste in black bags, but the system is already prepared for expansion with two additional fractions (types of waste).

By using coloured bags instead of multiple bins, households benefit from a simpler and more space-saving solution.

The sorting technology makes it possible to efficiently separate waste streams, while also reducing the number of bins and heavy transport in the urban environment. For residents, this means less hassle, and for the municipality, it is both cost-effective and environmentally sustainable.

Envac has extensive experience with sorting solutions and already operates around 20 similar facilities in Sweden and Norway.

Aalborg is the first municipality in Denmark to implement this solution, and the hope is that the project will become a model for other Danish municipalities.
