摘要：NH3 pollution is a significant problem in the poultry farming because excess NH3 can negatively impact chicken health and stunt their growth. Therefore, this study investigated the low-cost production of bagasse fly ash (FA)—a byproduct of the sugar industry—as an NH3 adsorbent. Hydrothermal carbonization and activation were applied to enhance NH3 adsorption using FA. In the experiments, the adsorption capabilities were improved using industrial waste materials mixed with bamboo char or red mud. The experimental results indicate that bagasse FA mixed with bamboo hydrochar under 10 % loading achieved an NH3 adsorption capacity of ～ 1.02 mg-NH3/g-adsorbent, or ～ 55 % of that of the commercial adsorbent. To avoid secondary pollution and provide the spent absorbents with an added value, their use in CO2 capture applications was evaluated. The results showed that the adsorbent had a 0.28 mmol-CO2/g-adsorbent capacity. ? 2023 Elsevier Ltd
