<p>A system (100, 200, 300, 400) for producing biogas from waste stream (101) comprising organic material comprises a liquid waste container (102) and a solid waste container (103). In addition it comprises a separator (104) for at least partially separating liquid fraction into the liquid waste container (102) and solid fraction into the solid waste container (103) from the waste stream (101) so that said solid waste container comprises more solid content than the liquid waste container. Furthermore the system comprises a communication means (106, 111) between the liquid waste container (102) and a mixer (105, 202) for introducing liquid from the liquid waste container to the waste stream portion comprising solid fraction in order to extract more liquid from said solid fraction.</p> |
