“…Parana law already requires the installation of biodigesters to treat the effluents generated by agribusiness activities, but this requirement does not yet apply to the capture/sequestration of these gases, in the case of this research, methane gas. It should be noted that effluent from biodigester should be treated prior to its discharge into surface water, as in the study by Zahrim (2018). Second, the BNDES needs to regulate the use of FINAME resources as a source of financing for the acquisition of biodigester technology by other starch and agribusiness sectors.…”
