In last one decade, numerous researches have been performed on the Black Soldier Fly (BSF) larvae to establish the optimal breeding condition in contradiction of the computational temperature, wide sort of substrates and sub optimized feeding ratio. Even though the considerable number of methods has been already established and supervised, there have been a technical lagging always been predominantly in the form of egg hatching rate, moisture tolerance, drainage and rearing requirements to categorize the obtainable alternatives. In order to inculcate the reimbursements of the existing technology and fulfil the knowledge gaps pertaining, in this paper, we propose a monitoring based real time hatching system which comprises the technicality and precious management skills. This review emphases a comprehensive nutrition technique for BSF larvae by means of different fodder acclaim abilities in association with the adaptability of sewage water and accentuate the change in the behavioral characteristics of the adult as well as on larvae stage, which can open a new economic window in sustainable waste management technique and will be capable of addressing multi-dimensional solution in the form of green and novel alternative.

With the rampant boom in faecal sludge (FS) collection and management in line with Indian government’s agenda, quite a few urban local bodies (ULBs) in Telangana such as Greater Warangal Municipal Corporation (GWMC) initiated into establishing faecal sludge treatment plant (FSTP) in collaboration with experienced private technology partners such as Banka BioLoo Limited. FSTPs were so designed with minimal mechanical components to regularize it as a popular choice for rural and sub-urban. The GeoTube based technology makes use of an organic flocculant to maximize the floc formation and thereby the water recovery. Post-flocculation the sludge is fed into a semi permeable polypropylene trap (GeoTube®) with a pore size of 0.3 mm. The method of dewatering the septage with the aid of GeoTube was so designed to ensure greater than 98% efficacy. Ultimately, the above effluent gets polished with a series of tertiary units such as pressure sand filter, activated carbon filter, UV disinfection, etc. The permeate meets the inland water disposal standards and is used to maintain the green belt in and around the plant. The trapped biosolids are self-composted for more than two months inside the filled tubes. Further, the debagged material is analyzed to ensure compliance with physico-chemical, metallic, and pathogenic limits. Afterward, the final materials pulverized, packed, and distributed amid the local farmers to be used as a soil conditioner. The FSTP has been successfully running for about two years now and has to date treated more than 2 million liters of septage of which recycled almost 1500 kL of water and 35 tons of biosolids.

The moisture content of municipal solid waste (MSW) and local precipitation events lead to the leachate generation from MSW land lls. The high concentration of organic pollutants in land ll leachate makes it hazardous, requiring treatment before disposal into the environment. Land ll Leachate is most commonly treated by reverse osmosis (RO), which generates large volumes of wastewater termed as RO reject. This investigation aims to stabilize the RO reject through an inexpensive and effective bioremediation strategy. A bench-scale aerobic suspended growth reactor study was conducted using three commercial conversion agents, namely EM.1, Bokashi powder, and coir pith powder. Overall benchscale e cacy of 63% was achieved in this study. The onsite studies were conducted in 7.5 kL arti cial ponds with 46% e cacy amid atmospheric in uences and constraints. In contrast, the control pond with no conversion agents showed an increase in pollution concentration over the 100 days of retention time.The ndings revealed that the investigated technology had a marginally lower evaporation rate and performed relatively well compared to traditional solar evaporation ponds. Moreover, the technology can be easily scaled-up and readily applied for RO reject treatment in MSW land lls.
