Catching the plastic waste of the main transporters: the rivers, before it enters the much bigger ocean is of paramount importance. Allseas has gained experience in designing and building these systems, mostly for domestic use.  The aim of this project is to design a river plastic removal system capable of reducing the plastic emission of the Klang river.

The Dutch Railways (NS) is redesigning their exterior cleaning protocols. This includes the application of functional coatings to increase the cleaning interval, as well as redesigning the way trains are currently automatically cleaned. The sides of the trains will be washed once every three months; however, the heads should be washed every two weeks.  This cleaning should take place with minimal additional movements or withdrawal from the operation schedule, and most importantly it should comply with environmental rules and sustainability

Materials made in bio-based circular value chains can significantly reduce the carbon impact of their value chains. The case involves a comparison between circular and bio-based circular materials. You can choose your own circular material! Then we help you to close the loop and show the real impact over multiple lifecycles. Our specialists at RHDHV help you to zoom into different processes and try out different material routes, to find the most impactful material for the circular economy.

By applying our modular beehive monitoring system and Earth observation to nature-based solutions, we aim to deepen humanity's understanding of pollinators. BeeSage already serves beekeepers in 10+ countries, and would like to develop a software product to add value for a different stakeholder - local municipalities. The goal is to design a geographic information system (GIS) that alerts policy makers on environmental risks and guides decisions on pollinator conservation.

The challenge is to develop smart grids and green energy systems for the Port of Maassluis and Loods M, fostering a self-sufficient and emission-free maritime environment. To transform the Port of Maassluis into a pioneering hub for sustainability and to establish Loods M as a leader in local green energy provision and smart grid technology.

Our aim is to create facilities which can be placed anywhere in the world for growing fish larvae to juvenile fish which then can be used in traditional outgrowth facilities. We need your knowledge and innovation to develop a relocatable marine culture facility based on the principles of TinyOcean as a fully circular and closed system which can be used in those places who are in need for local food production (protein transition) and nature restoration by means of growing fish larvae to fish fry.

For the building sector sustainability goals come into conflict with the necessity to create suitable housing and infrastructure. Biocomposites offer promising results. The strengths, weaknesses, opportunities and threats for (upscaled) usage of biocomposite need to be determined. For one to be determined case study, a draft design will be made.

Rijkswaterstaat will renovate a large number of – mostly big - locks in the coming decades, since they are reaching the end of their life span. It has to be done in a sustainable and cost-effective way. Sustainability, life cycle costing, availability, maintainability, innovation, future readiness and standardization will be leading concepts.  

Together with Hoogheemraadschap Delfland and RHDHV we are designing the waste water treatment plant of the future: Vergulde Hand in Vlaardingen. This treatment plant will be completely newbuild on a vacant piece of land and the focus will be on making it as sustainable and circular as possible. However, you also have to keep an eye on costs and local residents. This challenge brings a lot of possibilities! Compounds in the water that are entering the treatment plant can be valuable resources. Whether that is in energy, gas, hydrogen and water. Together with your team you will explore one of these opportunities.
