Applying technologies developed by itself that have patents
It has been selected by the Swiss Zinc company and the ZAR Foundation for the development of the preliminary engineering of two industrial plants that will be dedicated to the treatment of urban solid waste.
Gathered techniques has been selected by two Swiss entities for the use of technologies developed by the Spanish company, and who have patents that they own, in the preliminary engineering of two industrial plants that will be dedicated to the treatment of municipal solid waste and sewage sludge.

One of them, promoted by the company SwissZinc, property of the Swiss Waste Management Association (VBSA), apply to two technologies from Técnicas Reunidas (ZINCEXTM and ECOLEADTM) for the recovery of zinc, copper-cadmium cement and lead through the treatment of ashes from incinerated solid waste.
These processes will be carried out in a plant that will be installed in the industrial complex that the company KEBAG, one of the seven that make up the Association, owns in the town of Zuchwill and will have a treatment capacity of 40.000 tons of ash per year. Its launch is scheduled for 2025.
The Spanish company Técnicas Reunidas is one of the most important companies in its sector on an international scale, with a presence in 25 countries and a history of more than 1.000 industrial plants throughout its 60 years of experience.
La Swiss Waste Management Association (VBSA) It is considered the leading entity in waste management in that Central European country. It brings together the operating companies of the Swiss plants that carry out these activities and has considerable influence on the waste management policy of its country.
The other, promoted by ZAR, a foundation created in 2010 to promote the sustainable use of waste and resources, will use technology PHOS4LIFETM from Tecnicas Reunidas for the recovery of phosphorus through the treatment of ash from sewage sludge.
The plant in which these operations will be carried out will also be installed in the KEBAG industrial complex and will also have a treatment capacity of 40.000 tons of sewage sludge ash per year. It is planned to enter service in 2026.
ZAR is a Center for the Sustainable Use of Waste and Resources which defines itself as an “ambassador of the sustainable circular economy” whose main objective is the recycling of materials from the thermal treatment of waste.
In both cases, the selection of Técnicas Reunidas has occurred once it has successfully completed three previous phases: proof of concept of the technologies, feasibility tests on a laboratory scale and demonstration in a pilot plant. The preliminary engineering that the Spanish company is now facing will give way, if it is successfully closed, to the license sale, technology supply and basic engineering that will be developed over the course of a year before tackling the construction of the two plants. industrial.
Javier Limpo Orozco, Director of the Proprietary Technologies Development Division of Técnicas Reunidas, has pointed out that “these two projects are part of the growing range of activities that the company has been carrying out over recent years in terms of the circular economy within its energy transition strategy and prove its ability to compete with its own technologies in countries that are leaders in this area.”
Currently, the management of the growing generation of Urban Solid Waste (MSW) and the initiatives to prevent it from ending up in landfills are being addressed in Europe through two lines of action that are not exclusive: some countries, such as Spain, are preferably opting for recycling to give a second life to this waste, while others, such as the Scandinavian countries and Switzerland itself, They mostly apply the alternative of incineration.
Therefore, the fact that Técnicas Reunidas has achieved the selection of its technologies in one of the most active countries in this field is of special significance. In particular, it should be noted that SSwitzerland is a European pioneer in phosphorus recovery coming from sewage sludge, which is precisely the objective of the project that the Spanish company is developing to ZAR.
