Head of Business Development Energy from Wastewater
Proposed Session Description
We want to show how energy can be generated from wastewater to heat and cool buildings. Wastewater is a completely underestimated energy source, which is available in large quantities, especially in urban areas, and can contribute significantly to the decarbonisation of the building sector.
Heat from wastewater can revolutionise the heating market. We would like to show how this works, what it costs and why the concept is experiencing a successful roll-out in Europe.
Diversity and Inclusiveness
This session addresses climate and environmental protection and aims for an environmentally friendly, healthy and just world.
Learning Objectives
The first objective is to explain why wastewater contains so much energy and what you could do with this energy.
The second objective is to explain how easy it is to obtain energy from wastewater and use it to heat or cool buildings.
The third objective is to show how much energy production from wastewater costs and that it is an excellent business case.
The fourth objective is to show how easily a project can be implemented and why this energy source is becoming increasingly successful in Europe.
Has this session been presented before?
Yes
When and Where?
In Europe, where we are successfully implementing this approach, we regularly present the topic.
Target Audiences Level of Expertise
Level 1 - No prior knowledge needed.
Session Format Details
20-minute presentation followed by Q&A

Anything else you'd like to tell us about your session proposal?
We would very much like to present and discuss our topic, as we consider an international exchange on the future question of climate protection to be essential. We find it exciting to learn from each other whether and where ideas can be implemented in a similar way and which hurdles can be overcome and how.

Full Description
Challenge: The session addresses the question of how to decarbonise buildings in urban space. Buildings are responsible for 28% of global CO2 emissions, largely due to their heating and cooling needs. In cities and metropolitan areas there is a lack of space and technology options to generate and provide green heating and cooling.
Solution: Using what is already there: energy from wastewater. Every day we flush vast amounts of energy away through the sewerage system and lose it instead of using it. Energy from wastewater can be easily recovered. This is energy-efficient, cost-effective and takes place invisibly underground. This energy can be used to heat and cool buildings.
Applicability: Wherever there are people, there is wastewater. Wherever there are people, there is a need for heating and/or cooling. So supply and demand match perfectly. Energy recovery from wastewater can be realised almost anywhere in the world. This approach can contribute significantly to the decarbonisation of the building sector.
The participants will understand that many technologies are already there, but the way to implementation is unclear. People who have not done so before will have to work and talk with each other. Looking beyond the horizon opens up potential that is closer than you think.
