Multiple Cashing with Circular Material Value

So far, Venturial and data-proof were the missing link in circular economy concepts. While the new Dutch cabinet debates that “sustainability is far too expensive”, architects and builders are calculating their profits, are drawing carbon credits over blockchains into the models and ensure a Return on Investment (ROI) close to Year 1-2.

“Farmers, Construction, and Blockchains” was the report presented to the Dutch government by our Dealin.Green consortium in 2025 regarding affordable, healthy buildings without nitrogen problems in our country and the end of EU nitrogen-rivers. Farmers, architects, constructors have joined forces in this Dutch circular economy consortium that’s an example for EU. We can only change systems together.

Farmers build up the soil using AI soil scans and biochar, carbon, and receive carbon credits as a revenue stream. Biobased builders retain the carbon in the system for longer (40-100 years) and therefore can also receive carbon credits as a revenue stream. PLACE | TIME | SPACE as an economic modelmaker.

Farmers solve nitrogen problems and CO₂ sequestration. They can finally choose the right crops with regenerative roots and be rewarded for it in the blockchain models. Biobased construction does the rest. Breathing buildings. Carbon credits in the building’s financial models.

Rootz Innovation Center in West Brabant has signed a covenant with materials expert campus Brightlands in Venlo regarding biocircularity, and with that, the circle is complete. Biobased is no longer a problem, but a solution.

Even VDL is working on it with fiber-enhanced polymers for their bus-interiors.

Venturial remains the central hub of the system. WHY? Because designers do not want to use whole wood panels again. They need powders to make membranes. Or other shapes. Designers are designers. They want freedom to design!

In economic sense, with a circular economy, you can effectively push maintenance costs out of the financial system and thus achieve an ROI close to Year 0. However, you can only bring the financial returns forward in the financial ROI model if you work with a guaranteed Life Cycle Analysis (LCA). A guarantee that the materials can be reused as Grade A-B-C. A clear analysis. A materials passport for the reuse of powders.

Venturial makes sure that inside the powdering process (with 20x less energy use than regular) there’s an analysis and a separation. The powders come out in classes. Grades. So quality is clear and reuse afterwards is guaranteed again.

But Circular Economy is ECONOMY, so let’s look at the economic profit mechanisms of healthy materials with a guaranteed rest value.

The first buildings were made in 2015. A city hall, healthy school, healthy sports hall, healthy hotel, healthy homes. Let’s look at the specifics of the city hall Venlo. The city had already been a cradle-to-cradle municipality for 10 years, so circular financing turned out to be a simple exercise in patterns. How did the calculation work?

• Budget for a building that is healthy across a few lines. Passive for energy and water use, breathable. Grey water circular with a helophyte filter. Sunny sides solar, photovoltaic windows. Shady sides with plants that were also all chosen to… purify.
• Use healthy, minimally outgassing materials. Water-based glues and dyes. Carpets are held together with gecko-foot technology (Van der Waals forces, nanohairs) instead of glue. And the patterns are mottled, so that 100% reuse is no longer a color variation problem. Biomimicry Design = Nature Design. Systems thinking!
• Due to the unavoidable flame retardants in the furniture, traces of toluene and benzene are captured using plants from the NASA lists. Because being data-driven—well, that is a requirement due to ISO standards.
• The building ended up costing 13 million more than usual without all these sustainable, healthy features. But… the architect calculated a Return on Investment (ROI) of Year 0 using models from Maastricht University. Circular financing is not rocket science.
• Did Year 0 succeed? Not quite. But they came close, and the city council took half an hour before unanimously and wholeheartedly saying YES. 13 million extra with an ROI of Year 0. We would all like that.

The Step-by-Step Explanation of ROI in Year 0-1-2

Cash flows work just like ecology. Economics and ecology share the same word root. Oikos. Greek for household. Interconnected. Costs and revenues are either asset (solid, solid matter, the money is tied up in stones) or cash flow (liquid, fluid, the money is readily available). But now that value is interwoven into data and everything has become digital, infinite natural patterns are possible.

How did they do it at this Venlo municipal office?

• In the very first circular economy model, all revenues and costs within the scope of the “municipal office” were included. Absenteeism costs, maintenance savings, residual value, productivity, training new staff, PR, headaches, drunken decisions due to excessively high CO₂ levels in the meeting rooms. Everything was assigned to qualitative scientific value. In later models, it was expressed in the common denominator “energy value”. Data-models make that possible.
• The baseline measurement was an unhealthy barracks building from which the municipality was moving. A scientific method of quantity and quality was employed, using questionnaires and comparable units of measurement in time and space.
• The architect was chosen for his vision, not so much for the “beautiful” design. Healthy function stems from form, material choices, airflow velocity patterns, and the achievement of optimal ventilation. A purifying building, both internally and for the polluted neighborhood where the building was to be located.
• The initial investment was 13 million more expensive ⬆️
• The maintenance budget was minimized. ⬇️ Let physics do the work, for example, by having a solar chimney handle 80% of the ventilation. An atrium and breathing outlets where the air is cleaned by plants. Warm air rises. The canteen was closed. Too much CO₂ and odor emission. A Swedish biomimicry architect, Anders Nyquist, already combined this in his Ecocycle Design schools of the last century with slow fans for wide-ranging distribution under ceilings. Everything is a design of heat intake, heat output, moisture bridges, and more. Maintenance budget was also minimized by pushing maintenance out of the system and leasing furniture, so the supplier could do his part of the circular economy.
• The residual value is validated with material passports, and that is where Venturial comes into play in current circular material models. If building materials are guaranteed to be reusable after their lifespan, the accountant is allowed to “value up” over time instead of “depreciate.” ⬆️
• Additionally, many costs were also “pressed” out of the system. ⬇️ Furniture rented, not purchased. Maintenance remained with the supplier. After their lifespan, the furniture is returned to the manufacturer for component reuse. In modern blockchains, that is a matter of smart contracts. But here, it simply happened using old-fashioned accounting and a spreadsheet. The calculation model is available on the website of https://healthybuildingmovement.com/. The matchmaker is a Dutch-German Interreg project that started in 2018.
• The lower costs ⬇️of absenteeism thanks to biophilic design have been incorporated into the model here. Other possibilities include PR savings, advertising savings for new staff, and more efficient communication models. If buildings effectively communicate their healthy and circular value, they act as magnets for modern youth, international visitors, and the press, and the building becomes a tool for education and inspiration.

• Companies want to keep their cash as liquid as possible. That is no longer a matter of ⬇️or ⬆️ but of 🌀Biomimicry patterns.

• Cash flows and assets simply follow a smart feedback loop 💎 ❄ 🕸
• The Maastricht University Chair in Health, Real Estate and Finance continues to monitor the many healthy buildings in Limburg from 2015-25 for monetary value and health value. Prosperity and wellness go hand in hand in a healthy building.

Are other value models possible? Of course.

But Venturial Value Models from the IBI² consortium are the best value models for material innovation because they not only hold biomimicry (energy-efficiency and healthy) in high regard, but also think very practically about data, blockchains, effective, efficient, bio-based methods, capturing CO₂ in the soil and building, and cashing the carbon credits by validating the official data-models.

Effective = Healthy. A breathing building. Efficiency means ensuring that not only the materials, but also the financial models are sound and become cheaper within the system.

Picture: drying, analyzing, and fiberizing, powdering. No more reusing whole wood panels, but complete design freedom with old materials. Venturial.eu

Bio-based construction will give carbon credits if the models prove that CO₂ is captured in the soil and materials. Trees such as pauwlonia trees or regenerative grasses. Lightweight and fast growing. The grasses can first be used for biogas, and then the sludge can be dried and used as building materials. Value upon value upon value.

But bio-based and healthy construction can also be achieved through reuse of (non) organic waste. What about dried, pulverized roof tiles? All possible! Dried and pulverized wood panels? Roof tiles made from Douwe Egberts coffee grounds? Dried hemp fibers, flax, bamboo, seaweed, tomato stalks, wheat husks, and more?

With Venturial, all material retain their value for years to come, and the residual value after its lifespan can be included in the full LCA.

No more devaluation but upgrading! Upcycling! Guaranteed returns can be captured at the beginning of the circular chain as ROI. The advantage is that data does not need to be released by the original manufacturer, who often relies on “patent protection”.

In short, “venturialing” for material passports in the circular economy has become a verb, and we are incredibly proud of that!
