The global focus on sustainability, energy transition, and the circular economy is rapidly intensifying.
A growing number of startups are leading the way, reshaping industries to be more environmentally conscious and resource-efficient.
At its core, this shift aims to transform the way energy is produced and consumed, reduce waste, and promote sustainable practices.
As awareness of environmental issues and climate change grows, cities around the world are becoming hotbeds for energy transition and circular economy initiatives.
One such city is Rotterdam in the Netherlands.
Upshifting Rotterdam’s green future
Rotterdam has an extensive energy ecosystem, and the city is leaving no stone unturned to accelerate energy transition.
The city’s energy transition and circularity ambitions are fueled by the close collaboration between the government, businesses and entrepreneurs, knowledge and research institutions.
At the heart of Rotterdam’s efforts is Up!Rotterdam, an initiative dedicated to providing startups and scale-ups with better access to talent, (international) markets, and capital.
Connected ecosystems are the strongest ecosystem,” states Up!Rotterdam.
Circularity is also one of Rotterdam’s top priorities. Through its Circular Economy Roadmap, Rotterdam aims to reduce raw material usage by 50 per cent by 2030, prioritising sectors like construction, green energy, consumer goods, and healthcare.
Rotterdam’s municipality has also introduced the Smart Energy Systems (SES) subsidy program to support the development of smart energy networks.
This program offers up to €100,000 for feasibility studies, experimental development, or pilot projects aimed at advancing the energy transition.
Fostering entrepreneurs contributing to a circular, inclusive, and digital city
Besides supporting initiatives and organisations, numerous startups are also working towards addressing some complexities to accelerate the adoption of energy transition and circular economy.
Up!Rotterdam supports these innovative entrepreneurs in scaling up their businesses by providing them with better access to capital, talent, and new markets and shaping a community that enhances peer learning.
It has gained insights into challenges faced by local startups and scale-ups, helping them identify effective approaches to support their growth.
Up!Rotterdam does this through a targeted approach — by connecting relevant parties, strengthening existing initiatives, and developing new programs as needed.
They also work closely with over 60 co-creation partners to connect, strengthen, and innovate, and provide access to a range of programs from organisations such as Techleap, RVO (Netherlands Enterprise Agency), Innovation Quarter, SES, CVN, EIT, and Dutchbasecamp, among others.
One of the key strategic partners of Up!Rotterdam is BlueCity, Rotterdam’s hotspot for circular companies. This model city now hosts more than 55 sustainable, circular entrepreneurs.
The startups’ creative solutions take a unique approach to reducing waste, enhancing energy efficiency, or reimagining resources, making a tangible impact on the journey to a greener, circular economy. Some provide offshore floating solar solutions, while others clean up the oceans and even bring human nutrients back into the cycle of life.
The Rotterdam region is a hotbed for such innovative and impactful startups and scaleups, and we spotlight 12 of these remarkable startups. These companies are redefining what’s possible in energy transition and circularity, paving the way for a brighter future. Let’s dive into the promising work each of these startups is doing to transform the Rotterdam region and inspire global change.
