Abstract: A method of treating waste comprises first separating the waste material into at least one first fraction, preferably with waste parts above a predetermined size of waste parts, and into a second organic-rich fraction, preferably with waste parts below the specified size of waste parts. Next the second fraction is separated into at least an organic-rich fine fraction and an organic-rich coarse fraction. The organic-rich coarse fraction is dry fermentation following which the digestate is treated together with the previously separated organic-rich fine fraction to obtain deposit and/or fuel.
