ABSTRACT:
It is described a method for manufacture of sanitised organic sludge, said method comprising the following steps: mechanical mixing of a cellulose containing component, a super absorbent and dewatered organic sludge; leading the mixture to a sanitising container; continuously supplying air to the sludge mixture until the desired temperature has been reached. The super absorbent increases the moisture retention of the sludge mixture, such that odor and leakage is prevented during composting. The cellulose component, preferably shredded newspaper, admits increased air supply to the sludge mixture. The method may be used to treat sewage sludge, hydrocarbon polluted soil and waste from fish processing or abattoirs.
