From a Toolbox to a Way of Thinking: How Symbioter Arrived at the 3R Approach

That question was a good place to start.

The limits of the toolbox

Looking at the results project by project gives you an impressive inventory. It also gives you a challenge. Each project was built around its own theme, partners and audience, so its tools naturally speak that project’s language. For a municipal planner, a utility manager or a local NGO, the starting point is rarely “which project made this?”. It is “what do we do with our rainwater, our wastewater, our nutrients – and who do we need to work with?”

A catalogue of tools, however well curated, still leaves the user to work out how the pieces fit together. And that is precisely where local action tends to stall: not for lack of technical solutions, but because of fragmented knowledge, sectoral silos and limited capacity to connect them.

Turning the question around

So we turned the question around. Instead of asking what the projects offer, we asked what a local water actor actually needs to be able to do. Looked at that way, the results began to sort themselves naturally around three practical themes, which became the 3R approach:

• REUSE – rainwater and stormwater management: climate adaptation, nature-based solutions, heavy-rain mapping and flood risk tools.
• RECYCLE – wastewater treatment and safe reuse: regulation and risk management, small-scale and modular systems, and managing seasonal pressures.
• RECOVER – nutrient recovery and flow monitoring: turning waste streams into resources for agriculture and industry.

The shift is subtle but important. The 3Rs are not a new label for the same list of tools. They are a way of organising knowledge around the questions municipalities and utilities really face, and around the water and nutrient flows they manage every day.

One result, several roles

Once the material was organised this way, something interesting happened: the boundaries between the original projects started to matter less. A single project’s results now often contribute to more than one R. Work on small-scale wastewater systems, for example, informs both recycling and nutrient recovery, while tools developed for water reuse support recycling as well as stormwater thinking. The 3R structure lets results from different projects meet, complement each other and fill each other’s gaps – which is exactly what a purely tool-by-tool view could not do.

It also made the link between the 3 Rs visible. Stormwater, treated wastewater and nutrients are not separate worlds on the ground. They are connected flows, and the greatest benefits often come from handling them together.

From three themes to local symbioses

This is where the 3R approach connects to Symbioter’s central idea: water symbioses. A local symbiosis is a practical, small-scale collaboration in which municipalities, utilities, businesses and interest groups recycle, recover and reuse water and nutrients together, using nature-based solutions and proven treatment technologies.

The 3Rs give these collaborations a shared language. They help partners see where their activities already overlap, where one actor’s “waste” could be another’s resource, and where cooperation can deliver measurable environmental benefits – from reducing eutrophication to increasing resilience against heavy rain and drought.

Building capacity around the Rs

The same structure now carries Symbioter’s capacity-building work. Three training packages – one each for REUSE, RECYCLE and RECOVER – bring together knowledge from the nine background projects into coherent, user-oriented modules. Trained experts will take this knowledge into local workshops, study visits and hands-on events across the region. An international mentoring programme will then pair experienced organisations with municipalities and utilities that want to develop their own local symbiosis plans.

In other words, the journey runs from tools, to themes, to people and places: from what exists, to how it fits together, to how it is used locally.

Why this matters for the Baltic Sea Region

The Baltic Sea Region faces persistent pressure from eutrophication, climate change, urban growth and seasonal tourism. Solving these challenges needs more than good technology – it needs knowledge that is easy to find, easy to understand and easy to apply across sector boundaries. By moving from a collection of tools to the 3R approach, Symbioter aims to make proven solutions practical for the people who have to put them into action, and to support regional priorities such as the EU Strategy for the Baltic Sea Region (Policy Area Nutri), HELCOM’s Baltic Sea Action Plan and the EU Water Resilience Strategy.

The toolbox remains valuable. But the real step forward is learning to think in flows and partnerships – and the 3Rs are how we get there.
