Closing material loop or secondary raw material?

We know many examples from our surroundings:

KNOF furniture and partitions made of recycled materials,
KEMSO or Communal material circle: the order of hygienic paper for (local) municipal institutions and companies, with the inclusion of the "zero waste" circular criterion, which brings additional points to providers for supplying products from locally collected waste packaging (closing local material loops is encouraged).

Examples of public procurement to promote the KEMSO program or Communal material circle:

Municipality of Novo mesto: JN003683/2021 and JN004160/2023,
City Municipality of Ljubljana: JN008228/2018,
Public Holding Ljubljana: JN008344/2018.

Innovations help to meet environmental goals at the municipal level.

Consideration: Closing material loop or secondary raw material

Innovative technologies meet Copenhagen's environmental goals

Why was an innovative solution considered?

After setting a goal to become carbon neutral by 2025, Copenhagen is now changing the way it manages energy. A key requirement to achieve this goal is a significant reduction in energy consumption from street lighting. For this purpose, it was necessary to replace almost 20,000 street lamps.

The City of Copenhagen's lighting objectives were as follows:

replace high-pressure sodium lamps on urban residential roads, major streets and highways with efficient, custom-designed LED lamps;
achieve significant energy and CO2 savings so that the city can reach its goal of carbon neutrality by 2025;
improve the quality of street lighting for greater safety and comfort;
combine lighting control with traffic density data to adjust lighting levels in the future based on road use;
create a central management system for efficient management and control of street lighting.

What was done differently?

The public contracting authority chose the competitive dialogue procedure. The evaluation criteria were balanced: 25% price, 25% organization and execution of the task, 20% lighting solutions, 30% energy and environmental properties. The process took 16 months until the contract was signed.

What was the result?

By switching to LED lamps, energy consumption was reduced by 57%, and at the same time, the carbon footprint and maintenance costs were reduced (1.6 million EUR per year for an investment of 26 million EUR).
