The environmental impact of livestock by-products presents significant challenges, particularly in regions with intensive farming and high pollution levels, such as the Po Valley. This study evaluated effectiveness biochar wood vinegar reducing gaseous emissions during laboratory-scale storage slurry, digestate, liquid fractions. Various types applications biochar, both without vinegar, were tested across three independent incubation periods varying durations. results showed that ammonia (NH3) lower from slurry compared to raw digestate fraction, while methane (CH4) exhibited opposite trend. Pyrolysis effectively reduced NH3 by 47% on average when applied a 5 cm surface layer. However, its was inconsistent mixed into material or produced via gasification. Biochar activated significantly 61%, but it also led increased CH4 CO2. Nitrous oxide (N2O) detected only after at least one month higher used cover alone vinegar. Overall, applying activating proved effective by-products. varied depending type method application, respect emissions, highlighting need for careful consideration using vinegar-activated biochar.
