“…Solid waste creation is a global dilemma due to development and industrialization. About 1.3 billion metric tons of municipal solid waste (MSW) is generated annually in the world and this quantity is expected to increase about 2.2 billion tons by 2025 [12][13][14][15][16][17]. The important thing is that the organic waste is all zero cost materials.…”

Resource recovery and recycling of organic waste is a great challenge in the world. The unmanaged organic waste causes a great damage to the environment and the public health both in the developing countries and industrial parts of the world. In this research, an innovative method was adopted to generate bioelectricity from the organic waste by using the Microbial Fuel Cell (MFC). Various types of organic wastes such as livestock waste, food waste, fruit waste were used as the substrates of the microbial fuel cell. All the experiments were carried out in the same sized one chamber microbial fuel cell and the similar electrode materials. It was observed that all the organic wastes can be used to generate bioelectricity through microbial fuel cell. The generated electricity can be used in several environmental monitoring sensors and can be used as an alternate power source in the developing countries. The by-products of the bioelectricity generation can be used as soil conditioner in the organic depleted soil and agricultural fields.

“…With the improvement of people's living standards , the proportion of food waste (FW) is also increasing year by year, being considered to be one of the largest groups of organic solid waste in the world, and its generation rate is rising steadily (1,2). FW mainly comes from household kitchens, restaurants, canteens, and food processing industries (3). Among them, household food waste (HFW) is getting much attention owing to its high organic content and excellent source of value added products (4).…”

In order to explore the effect of added bacteria on microbial community and determine the dominant bacteria in the aerobic composting process of household food waste (HFW), two groups of HFW composting experiments were conducted for 30 days. The final degradation rates of the two groups were 69.95% (group A, natural composting) and 73.52% (Group C, composting with added bacteria), respectively. 16S rRNA high-throughput sequencing was used to analyze the changes of microbial community in the composting process. As the result displays, at the classification of phylum level?the relatively abundant bacteria of two groups were Firmicutes, Proteobacteria and Cyanobacteria. At the classification of genus level, Pediococcus is the dominant bacteria of group A, which performed better in maintaining the microbial community stable in the later stage of composting, while Weissella accounted for a relatively large proportion of group C and behaved well in promoting the final degradation rate of composting. The proportion of Ochrobactrum in the early stage of group C is considerable and it is closely related to the removal of odour during composting. The relative abundance of added bacteria was always in a rather low level?suggested that the way they affect the composting process is to change the proportion of dominant bacteria in different stage of composting. This experiment provides an important reference for improving the microbial degradation efficiency of HFW .

Food and Market Waste–A Pathway to Sustainable Fuels and Waste Valorization

et al. 2019

Food and market waste (FMW) is one of the most abundant unrecycled products which poses waste management issues and negative environmental impacts. Thermo-catalytic reforming (TCR) is a pyrolysis based technology which can convert a wide range of biomass wastes into energy vectors bio-oil, syngas, and char. This paper investigates the conversion potential of FMW into sustainable biofuels. The FMW was processed using a laboratory scale 2 kg/h TCR reactor. The process produced 7 wt % organic bio-oil, 53 wt % permanent gas, and 22 wt % char. The bio-oil higher heating value (HHV) was found to be 36.72 MJ/kg, comparable to biodiesel, and contained a low oxygen content (<5%) due to cracking of higher molecular weight organics. Naphthalene was detected to be the most abundant aromatic compound within the oil, with relative abundance of 12.95% measured by GC-MS. The total acid number of the oil (TAN) and viscosity were 11.7 mg KOH/g and 6.3 cSt, respectively. The gross calorific value of the produced biochar was 23.64 MJ/kg, while the permanent gas showed a higher heating value of approximately 17 MJ/Nm 3 . Methane (CH 4 ) was found to be the largest fraction in the permanent gases reaching over 23%. This resulted either due to the partial methanation of biosyngas over the catalytically active FMW biochar or the hydrogenation of coke deposited on the biochar in the post reforming stage.
