Abstract
A recycling process for garbage containing a high proportion of paper where printed paper is first separated from the garbage. The garbage is then into pieces and light and heavy components are separated out in a classification tank. The remaining organic mass suspended in water is hydrolyzed and subjected to anaerobic digestion followed by aerobic co-composting. The resulting solid is a high grade fertilizer while biogas produced by the process is converted to electrical energy in a combined cycle installation.
Claims19
A method for recycling and utilizing garbage which comprises:
- separating printed paper;
- cutting the garbage to about 3-5 cm pieces;
- subjecting the garbage to water canal floatation;
- collecting light floating products;
- precipitating heavy products;
- cleaning organic mass suspended in the water;
- hydrolyzing the organic mass at a pH range of about 9.5-10 at a temperature range from about 80-100° C.;
- subjecting the organic mass to anaerobic digestion in a thermophilic region to produce biogas and sludge;
- collecting the sludge;
- and
- subjecting the sludge to aerobic co-composting at a temperature of about 60° C. to produce humic-chemical-organic mixed fertilizers.
A method for recycling and utilizing garbage which comprises:
- floating the garbage in water;
- hydrolyzing a suspended organic mass;
- and
- digesting the organic mass anaerobically to produce biogas and sludge.
