Abstract

In this work, a simple model was created to estimate the benefits of replacing the LPG, currently used in flame weeding, with the syngas generated from a biomass gasification system. Results shown that 60.1 kg ha-1 of agripellet are enough to substitute 16.4 kg ha-1 of LPG when a gasification efficiency of 70% is considered. The model shown a CO2 generation of 49.8 kg ha-1 for each treatment using the LPG device and 94.5 kg ha-1 for the biomasspowered weeder which is, however, a biogenic source of carbon with a neutral impact on the climate. Moreover, for the gasification facility, a 3.3 kg ha-1 co-production of char was considered which led to the possible stock of 9.6 kgCO2 ha-1 each treatment. Eventually, the proposed model suggests that a net saving of 58.5 kgCO2 ha-1 can be realized if LPG flame weeding treatment is replaced with a syngas-powered flame weeder.
