Anaerobic digestion (EA) is gradually a widespread technique for treating food
waste while producing biogas.
Agustini et al. (2020) investigated the possibility of using raw tannery wastewater
as a substitute for the nutrient supply in the anaerobic co-fermentation of two solid
tanneries with respect to energy efficacy, waste treatment efficacy, as well as
economy. The results showed that the use of tannery wastewater as a nutrient source
for the solid tannery waste AD was sufficient from the viewpoint that the three
wastes were treated simultaneously. There was biogas production of only
1.9 Æ 0.3 mL/VSS. However, the methane present in the biogas reached 33% at
the beginning of the process, which shows that there is methanogenic activity and
EA was founded. The cost analysis showed that wastewater treatment and solid
waste disposal costs were reduced by 23% and 18% of electricity consumed as well
as 11% and 8% of heat consumed, respectively.
Tongco et al. (2020) aimed to improvise the process of the basic sludge degeneration with the help of the lipase and protease enzyme, and the optimum ratio of
these two enzymes is evaluated. Three types of the Korean WWT plant are used for
the enzymatic hydrolysis of the basic sludge. Lipase as well as protease was
separated from enzyme manufacturing secondary sludge microbes, which were
taken at eight diverse fermentation places in Korea. The major degradation of the
sludge by enzymatic hydrolysis was followed by the measurement of the decrease in
the suspended volatile solids (VSS) of the suspension-enzymatic mixture at 41
C
and pH 7.1 for 72 h. The primary mud enzyme mixture from Ulsan treated with 1:3
lipase protease was optimal with a 33.3% reduction in VSS. Methane biochemical
potential (BMP) assays for the optimum enzyme mixture were cast off to measure
the possibility of the hydrolytic substrate for further degradation (VSS reduction).
The significant decrease in VSS as well as the developed methane and biogas
production treated with primary enzymes are related to the degradation of the
polymer organic complex materials, which leads to effective use of microbes in
the process of anaerobic digestion.
Ngan et al. (2020) examined the process of anaerobic digestion (EA) of the
decomposition of organic substances by microbes in the absence of oxygen where
biogas as well as the methane, a key source of renewable energy, is generated. The
chapter also dealt with current research results on the generation of biogas from the
co-digestion process which is essentially anaerobic, by mixing farming by-products,
concentrating on rice straw and animal compost as substrates. The use of the
biological suspension of the process of fermentation in marine culture activities as
well as agronomic cultivation is also discussed. When using only a source of the
organic material such as pure substrates, it is hard to raise the AD procedure for the
unevenness of the nutrient, the deficiency of suitable bacteriological populations, as
well as the impact of operating restrictions. Since rice straw is rich in cellulose, it
must be pre-treated before being placed in the anaerobic fermenter. Table 3.4
summarizes the literature on acidogenic organisms.
Uma et al. (2020) examined anaerobic fermentation technology for converting
organic substrates into biomethane potential. This study evaluates the common
digestibility of food waste (FW) as well as pasture (SG) in different ratios as well
