ZAR CO2 Competence Center – Status Report Autumn 2023
By Daniel Marxer, Stefan Ringmann, Walter Furgler / ZAR CO2 Competence Center KVA Linth
At the ZAR Foundation's CO2 Competence Center at the KVA Linth, fundamental research on the capture of CO2 at Swiss waste-to-energy plants, as well as its transportation, utilization, or storage, is being conducted. The primary goal is to support and advance the implementation of this technology in Switzerland.
The competence center has been operational for approximately 1.5 years, and the processing of the work packages, which were contractually agreed upon between the FOEN (Federal Office for the Environment) and ZAR in March 2022, has commenced. It became evident quickly that a sequential processing of the packages is not conducive, but rather work must be done simultaneously on the various topics.
This status report presents the previous activities, progress of the work packages, and initial findings from the individual work packages in summary.

Waste to energy, indispensable cornerstone for circular economy
Scientific Publication by Brunner & Morf
At the suggestion of Professor emeritus Paul Brunner, a specialized publication on the significance of waste-to-energy plants (WEPs) in the circular economy was authored last year, commemorating the 40th anniversary of the scientific journal "Waste Management and Research".
For Professor Brunner, who is counted among the founders of the goals and principles of Swiss and Austrian waste legislation and previously served as an advisor to the German government and the EU, it was crucial to present the history and role of WEPs in the circular economy. This included considerations of the latest advancements from flagship projects initiated by the Canton of Zurich and the work of the ZAR Foundation, as well as providing a forward-looking perspective within this context.

Status Report 2018
THERMO-RECYCLING – Efficient recovery of valuable materials from dry bottom ash
The recovery achieved and the associated savings of 60,000 tons of CO2 per year (equals 0.6 t of CO2/t of dry bottom ash or 0.1 t CO2/t municipal solid waste) set new standards worldwide. In addition to the major ecological advantages, the great economic potential of dry bottom ash has also been proven. In 2017, metal revenues of over CHF 95 per ton of dry bottom ash delivered have been realized. The treatment process also sets new standards for industrial plants regarding dust emissions.

Life cycle assessment of the phos4life process
ETH Zurich has drawn up a comprehensive life cycle assessment of the phos4life process, which the ZAR Foundation is developing in cooperation with the Spanish industrial partner Téchnicas Réunidas on behalf of the Canton of Zurich. The study compares the production of phosphoric acid from sewage sludge ash with the primary production of phosphoric acid from raw phosphate using the Phos4life process. The study includes an English summary.
Factsheet
Fact sheet for the discussion between the director of the cantonal office of building and the political leaders of Zurich incineration plants on the subject of recycling and landfilling of bottom ash from 27.11.2017 (German only).
Status Report 2017
At the end of October 2016, after a lengthy construction and commissioning phase of the world's first treatment plant for dry bottom ahs, all processing lines for the separation of metals from the bottom ash were available for operation. Although the focus of the activities was concentrated on operational processes and little time has been found to optimize the plant, the plant's performance figures are encouraging. After about half a year of continuous operation, an initial interim balance can be drawn up.

Methods Report
In order to ensure and improve the reliable assessment of the quality of residues from thermal waste treatment, but also to determine the economically and ecologically interesting potentials of recyclable materials more reliably, ZAR worked intensively in cooperation with BACHEMA AG, Schlieren and supported by the Canton of Zurich on the optimization of the corresponding methods.
After intensive further development of individual processes over the last 5 years, this book of methods represents today's state of the art in the knowledge of practical methods covering the entire spectrum of residue fractions of thermal waste treatment. With the publication of this document, this knowledge is now to be made available for practice.
