Carbon dioxide sequestration in chemicals with applications in agriculture is one of the active research fields at global scale. The aim of this paper was to study the CO2 sequestration in piggery wastewater. The obtained products are ammonium carbonate, ammonium bicarbonate, and carbamate, compounds with various agricultural and industrial applications. It was investigated the biological treatment of piggery wastewater for organic carbon and nitrogen removal in a combined anaerobic–aerobic sequestration batch reactor (SBR) system. The wastewater treatment plants are a source of greenhouse gases (GHG) emissions such as CO2 or nitrous oxide (N2O). SBR system plant has been proposed as a technology to convert CO2 and wastewaters into valuable products (hydrogen, methane, organic compounds) by intake of generated gas in the system as a source of reducing power. The laboratory investigation was performed to assess the feasibility of CO2 absorption and the quantities of Nitrogen-containing compounds decreasing. It was found that by applying this technique, the quantities of organic carbon and nitrogen-containing compounds are significantly reduced. Besides the CO2 capture and, consequently, the decreasing of GHG amount, the obtained products can find large scale application in agriculture for plant growth, in industry, and even in tissue engineering.

Keywords: carbon dioxide, sequestration, nitrogen, piggery, wastewater.
