Waste, Cement and Heavy Industry

​In order for Switzerland to achieve its 2050 net-zero goals, substantial decarbonization efforts are necessary in all sectors of the economy. Industries with large CO2 footprints are of special relevance, in particular as many of them can be considered hard-to-abate, i.e. decarbonization involves significant efforts and resources. Examples of these industries are cement and steel production, Waste-to-Energy (WtE) or the chemical industry. Given this importance for the success of the national and international decarbonization challenge, sus.lab has focused its efforts on supporting these industries to solve their biggest challenges.

As the largest emitting industry with total emissions of approximately 4.4 million tons of CO2 per year, Swiss WtE plants have been the starting point for sus.lab's work. Commissioned by the association of Swiss WtE plants, VBSA, we investigated what could be done with CO2 contained in the Swiss waste and determined that Carbon Capture and Storage (CCS) is the only viable solution at scale. Based on these results, we have followed up with concrete feasibility and scale-up studies. WtE carries even greater significance for Switzerland, as about half of the emissions are biogenic and thus carry potential for much-needed negative emissions.


Accounting for about 8 percent of Swiss annual emissions, the cement sector is another industry in need of decarbonization. Here, it is particularly the complex structure of emissions, composed of process and fuel emissions, that poses challenges. Over the last years, sus.lab has engaged with a number of industry players and will continue to support the industry on its decarbonization journey.


Our Projects

Phase 1: Study on “how to decarbonize” Waste-to-Energy plants in Switzerland
Topic Cover

Assessment of decarbonization options for Swiss WtE plants: In a first of a kind study, different options to decarbonize the WtE plants in Switzerland were explored and key results and take aways were presented. 

Status: Complete 

Phase 2: Conceptual design/feasibility for a demonstration with WtE plant KVA Linth

Feasibility of the CCS value chain at WtE plant KVA Linth: Together with the KVA Linth the whole value chain of carbon capture and storage was explored, demonstrating the feasibility and putting a price tag on the CCS value chain.  

Status: Complete 

Phase 3: Feasibility of a CO2 pipeline network in Switzerland

Conceptual design & rough cost estimate for a CO2 collection network: A feasibility study for a pipeline network connecting the 30 largest emitters in Switzerland was executed and different scenarios were explored. 

Status: Complete
