Abstract
There is disclosed a method of producing a soil remediant from liquid organic waste material in which the liquid organic waste material is concurrently pasteurised and digested by thermophilic aerobic digestion in the liquid phase in a single digester vessel. The organic waste material in the digester is maintained continuously at a temperature of at least 70° C. for at least an hour and the liquid organic waste material comprises at least 70% water and can be pumped. After a period of at least an hour a small amount of pasteurised organic waste material is removed and a corresponding amount of fresh organic waste material is added to the single digester vessel such that the temperature is maintained in a comfort zone of the thermophilic bacteria. In a preferred embodiment the thermophilic aerobic digestion is facilitated by micro-organisms including crenarchaeota. The liquid organic waste material can be combined with a microporous adsorbent. Also disclosed is a soil remediant comprising a microporous adsorbent and liquid organic waste material from the novel method. The microporous adsorbent may be a volcaniclastic sedimentary rock or diatomite or of vegetable origin such as biochar. The microporous adsorbent may be a powder or a granular material and may have particle sizes up to 2000 microns.
