The warm and clean City

Reference number
Coordinator Lunds kommun - Kommunkontoret
Funding from Vinnova SEK 500 000
Project duration May 2013 - January 2014
Status Completed
Venture Challenge-Driven Innovation – Stage 1 initiation

Purpose and goal

The project ´The warm and clean City´ has developed a couple of concepts for treating wastewater, which will be tested in the next stage of the project. By using waste heat more biogas can be produced from wastewater and by growing algae and extracting nutrients wastewater can be turned into a resource for producing new products. If we also use membrane technology then clean water can be produced. At the same time the surface area needed for treatment plants is reduced, which is essential for any growing city around the world.

Results and expected effects

The result of the project ´The warm and clean City´ is that two concepts for wastewater treatment have been developed where low-temperature waste heat is efficiently recycled and used to produce biogas, nutrients, clean water and other products. These concepts will be tested and evaluated in the next step. The final results are: provision for waste heat that currently lacks a broader market, new methods and products for businesses, and more efficient and better wastewater treatment for municipalities.

Approach and implementation

In the first stage of the project, the participants discussed and gathered information to identify and develop two new concepts for wastewater treatment, etc. The concept will then be tested and evaluated in the next step. The group had a wide range of skills and consisted of persons representing municipalities, companies and universities. It was also identified the need to include some more companies to the project team to strengthen and cross-fertilize the different areas of technology.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
