Our Challenges
Our call for ideas is meant for motivated start-ups that will explore the city and its port around the following challenges:

Challenge 1 – Biomass Feedstock
The port of Amsterdam is a hub for urban & interregional waste streams. We are looking for innovative technologies and processes that turn biomass residues & waste into valuable feedstock. With a business model that can be economically viable in less than 5 years. Click on the video for more information about this challenge.

Challenge 2 – CO2 Feedstock
As part of Amsterdam’s waste incinerations and water treatment operations, carbon dioxide of 99,9% purity is produced. We are interested in technologies that can harvest and convert this CO2 into a form which can be used for products & industrial processes, or upgrade its purity for potential users. Combinations with hydrogen gas or other fuels are welcome. Click on the video for more information about this challenge. Read also the article ‘So many opportunities for reusing CO2’.

Challenge 3 – Digital Solutions
Industry & society become increasingly data-driven. We are looking for start-ups that can make use of data, connectivity and smart algorithms as a basis for circular economy products, -services & -infrastructure. Whether this is done by mining existing data from the city operators and big data sources, or by implementing sensors, machine learning or artificial intelligence; we are open to your unique suggestions! Click on the video for more information about this challenge.
