The Swiss Federal Ordinance on the Avoidance and Disposal of Waste (VVEA) requires that mineral construction waste be processed and reused according to type wherever possible. This is precisely where "Baustoff-City" in Weinfelden comes in and is all about the circular economy. Frei Fördertechnik AG planned and implemented the wet-mechanical processing plant for BRT Baustoff Recycling Thurgau AG in Weinfelden, the centerpiece of the site.

New processing plant for BRT closes the loops in concrete production

The companies TIT Imhof AG and Kibag Kies Weinfelden AG are renewing their concrete and recycling plant in the south-east of the town. The joint venture under the name Baustoff Recycling Thurgau (BRT) AG aims to close the material cycles in the regional construction sector. Using state-of-the-art technology, mineral materials (contaminated and uncontaminated) are processed and the reusable components are recovered as high-quality building materials. The resulting building materials are used for the production of concrete or as gravel mixtures on regional road and civil engineering construction sites.

The new wet-mechanical processing plant is the central collection point for mineral waste from the canton of Thurgau and neighboring cantons and is state of the art. The ability to accept mineral waste by rail and remove gravel again can greatly improve the environmental compatibility of transportation. As the general contractor, Frei Fördertechnik AG developed the process engineering solution for processing the raw materials according to the desired target products and in the corresponding quality. It was also heavily involved in the planning and execution of the steel construction.

The plant concept was individually tailored to the client's requirements and the conditions on site. The aim was always to achieve the most efficient operation possible. The steel structure has external dimensions of 51 x 16 m and extends over three storeys, on which material, water and technology are processed. Material is primarily transported around the site via conveyor belts to reduce the number of wheel loader hours.

The new processing technology results in a much better quality of the recycling material, says Martin Feldmann, Managing Director of BRT AG. "Fines, which previously reduced the quality and caused large fluctuations, can be removed much more efficiently with wet mechanical processing. By closing the material cycles in this way, we are effectively combating the scarcity of resources. Because processing and reuse in concrete production take place on the same site, transportation can also be reduced. Bauwerk Schweiz continues to grow - which makes it all the more important to use the available primary and secondary raw materials as efficiently as possible. We want to make our contribution to this. "

The complete Baustoff-City will open in fall 2024. The site will then include the wet-mechanical processing plant (operations began in autumn 2023), a recycling site for dry processing and a concrete plant that can recycle recycled material.
