Vorwerk International Award Night 2022 (VIAN)

Project executor: SEVA, Sociedade Energética de Valdante, SA (Energetus S.A.)
Time frame: 2022
Type: CO₂ avoidance with local heat 

The future emission of carbon is prevented. The VCI-A are based on avoided CO₂ emissions in the cogeneration plant linked to the Somelos textile industry. We compare the aggregated CO₂ emissions to the overall emissions caused by heat supply in Portugal. To determine this value, the kWh of the local heating networks are set in relation to the general heat supply in Portugal. 

Project executor: Bigler KLG
Time frame: 2022
Type: CO₂ avoidance with local heat 

The future emission of carbon is prevented. The VCI-A are based on avoided CO₂ emissions and are verified from local heating grids powered by biogas plants. Thermal energy from biogas plants is put into combined heat and power units and distributed to nearby consumers afterward. We compare the aggregated CO₂ emissions to the overall emissions caused by heat supply in Switzerland. To determine this value, the kWh of the local heating networks are set in relation to the general heat supply in Switzerland.

Time: 2022
Type: Long-term carbon sequestration in biochar

When burned or decomposed, plant residues release the CO₂ they have bound. However, if plant residues are converted into plant charcoal in a pyrolysis process, a large proportion of the CO₂ is bound in the Biochar. Once this Biochar is spread on a field and incorporated into the soil, it is stable in the soil for over 1,000 years.
