A study on enzymatic hydrolysis of fruit and vegetable waste using waste activated sludge
Department of Civil Engineering, Indian Institute of Engineering Science and Technology, Shibpur, Howrah-711 103, West Bengal, India E-mail : cbiswabandhu@yahoo.com, debabrata@civil.iiests.ac.in Manuscript received 15 November 2017, revised 06 March 2018, accepted 07 March 2018 A rise in demand for renewable sources of energy, coupled with the uncontrolled rate in the generation of municipal solid waste (MSW) have led to the development of anaerobic digestion (AD) for stabilizing organic fraction of the municipal solid waste (OFMSW). It is well established from past studies that enhancement in the overall AD process can be achieved by improving the rate-limiting hydrolytic phase. The present study focused on improving the degree of hydrolysis of fruit and vegetable waste (FVW), which occupy a more than 60% of the generated OFMSW, by addition of waste activated sludge (WAS). The enzymatic action of the biomass present in the WAS brought about considerable enhancement in the hydrolysis of FVW with over 92% reduction in weight within 216 h from the onset of hydrolysis. In this regard, the size of the FVW as well as the amount of WAS added played significant roles.
