As part of the KLIMAtiv project, 22.1 t (approx. 34 solid cubic metres) of spruce roundwood were subjected to heat treatment in a shipping container. Heat treatment is one of the quarantine measures accepted by China and therefore an immediately applicable alternative to fumigation with sulfuryl fluoride (SF).
After the Plant Protection Service of Hamburg issued the required phytosanitary certificate (PSC), the treated wood was shipped to China. The partner for this part of the project was Claus Rodenberg Waldkontor GmbH in Kastorf.
The logs were heated using steam. Based on the amount of electricity required and a CO₂ emission factor of 363 g/kWh (German electricity mix 2024), a 96% reduction in CO₂ equivalents (CO₂e) is calculated compared to SF fumigation (22.2 t CO₂e per 40′ container). The recorded power consumption provides a realistic basis to estimate treatment costs.
