title: Management of food industry waste employing vermicomposting technology.
abstract: This paper reports the vermicomposting of food industry sludges (FIS) mixed with different organic wastes employing Eisenia fetida. A total of 10 vermicomposting units containing different wastes combinations were established. After 15 weeks significant increase in total nitrogen (N(total)) (60-214%), total available phosphorous (P(avail)) (35.8-69.6%), total sodium (Na(total)) (39-95%), and total potassium (K(total)) (43.7-74.1%), while decrease in pH (8.45-19.7%), total organic carbon (OC(total)) (28.4-36.1%) and C:N ratio (61.2-77.8%) was recorded. The results indicated that FIS may be converted into good quality manure by vermicomposting if spiked with other organic wastes in appropriate quantities.
