Dating with recycled materials in Apeldoorn




In Apeldoorn municipality, the management and maintenance department contributes to the realization of a sustainable, clean and safe municipality. Many of these things are reflected in the design, construction and use of Gemeentewerf Noord, which opened in 2019. Also discover the matching tool that provides better insight and a higher turnover rate of recycled materials.

There is a beautiful, multi-functional building at Apeldoorn’s municipal farm, which serves as a base for landscaping and ice control. On Monday 14 November, the farm was also a suitable setting for a meeting in Circle City Apeldoorn & Deventer.

The building is well thought out and built, with great attention to sustainable solutions. For example, the building and grounds fit perfectly into the way the management and maintenance department located here works towards a sustainable, clean and safe Apeldoorn. Martijn van Kampen, construction project manager of the municipality of Apeldoorn, told the visitors more about how circularity and sustainability in a broad sense played a role in the design and realization phase of this Gemeentewerf Noord.

“The work building,” says Van Kampen, “is on the site of the former police station. Initially, we investigated whether this building could not be transformed or could partially function as a structure for the new farm. But when it turned out that it was not possible, it was demolished and the 13,000 tonnes of rubble was used as the foundation for the new building and the pavement.”

Detachable

Van Kampen also said the building is gas-free and can be taken apart. An underground storage ensures that rainwater can be used as toilet and flushing water. This was a cost-increasing option deliberately chosen in the context of exemplary function (as government) and preparation for the future. In addition, six hundred solar panels on the ‘floating roof’ meet the energy needs. Other circular aspects concern the reuse of paving stones from the municipality and fences from the old farm.

Two large holes have been made in the roof, which also serve as part of the roof to the outdoor space, in which salt silos have been built in (photo above). In this way, as Van Kampen’s presentation showed, you get a lot of outdoor space, and the salt trucks can be filled much more purposefully. For example, salt is used more sparingly, and there are also benefits for nature. There is also a drying room for storing and recycling flowers along the road. It makes the streetscape much nicer and gives an impetus to biodiversity.

Bokashi

The themes of circularity, biodiversity, climate adaptation and energy transition received plenty of attention in the story of Michiel Bruins, the head of the management and maintenance department. Circularity comes into its own, for example when using the organic soil conditioner Bokashi (fermented organic material). In connection with biodiversity, not all leaves are removed anymore. What is still taken forms the basis of the circular fertilizer Bokashi.

“It requires a different way of thinking”, says Bruins, “both from our people and from the residents. In the past we would vacuum away all the leaves and leave a bare, clean street. We no longer do that in connection with the promotion of biodiversity. We have also replaced all petrol appliances with electric leaf blowers and lawnmowers. Our people really had to get used to the different way of working, but so did the residents. For example, we received reports that people had forgotten to sweep part of the street. So you still have to explain that it is a conscious choice and that it is better for biodiversity and our environment,” says Bruins.

Corresponding

The heads of the departments work with asset management with common goals and values.
It sounds obvious, but the practice is sometimes more difficult. Bruins: “The administrators should be more proud of our work and be more critical of their own role. Often people are too modest. It is important, for example, that we clearly indicate when we do not support something and therefore do not carry out ‘impracticable tasks’ for that reason.”

Match circular products

In Apeldoorn, work continues with Cirkelstad partner DuSpot’s circular matching tool. This recyclable materials dating site provides insight into the released materials and the materials already available in the circular storage sites. Mart Mensink (DuSpot) said: “Using our matching tool, an order can be placed in the system in three phases – tender, project or depot. As a result, you can match supply and demand already in the specification phase. This tool provides better insight and a higher turnover rate of recycled materials. This also limits the storage of released materials and gives you a better insight into their value. Products that have a lower turnover rate also become transparent and less attractive to store.”

The conclusion of this very informative morning was clear: Apeldoorn is strongly committed to a sustainable way of working. It concerns both the choice of product, the way in which processes are approached and the implementation, which also makes use of social return on investment.

Now it is still important to give the residents time and help them in the transition to a better environment. One of the programs for this is the public campaign Heel Apeldoorn Rein. Around three hundred volunteers already work weekly to keep Apeldoorn clean and to consciously manage space and the environment. “How wonderful it is to work together on these social challenges! Both with professionals and with residents, for whom we ultimately do it,” concludes Bruins.
