The global emissions of carbon dioxide (CO2) are known as the predominant source of global heating. However, the CO2 feedstock has numerous applications in different industries. The Carbon Capture and Utilization (CCU) is a valuable way to promote the valorization of a recycled and biological CO2. Therefore, we provide a sustainable business model and holistic analysis for the CO2 offer from biogas and biomethane industries to deliver added-value products and substitute the current use of fossil by-products and promote zero-net emissions.

 

The CO2 is a natural component of biogas produced by the fermentation of organic waste for the production of biogas and biomethane, along with other gases extracted from it during the filtration and concentration process. The holistic and business model analysis can help to understand the main aspects related to the offer of a recycled and biological CO2 from biogas and biomethane industries in Switzerland. This can identify how this production and consumption can deliver and capture environmental and social value (Bocken et al., 2014). This study can also reveal issues related to innovative possibilities of biological CCU applicationin a growing agricultural, food and beverage market and others.

 

Method: literature review, official documents/ reports, interviews.
