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.
