“…In recent years, following the increase in importance and role of seafood in human health, their consumption has also increased [7,8], such that fish consumption per capita in the last 45 years has doubled around the world [9,10]. According to FAO, global fish production was 167 million tons (146 million tons was for human consumption) and per capita consumption reached 20 kg in 2014 [7,11,12]. Iran's fish production was about 1 million tons and per capita consumption reached 12 kg in 2018 [13,14].…”

The aim of this study was to investigate the estimation and management of fish and shrimp wastes in Bushehr province. Twopart questionnaire including the demographic information, and fish and shrimp waste disposal method were completed for 91 stores and 636 households. The quantity of generated wastes was estimated based on the 3 different Scenarios. In addition, the waste generation factor were calculated for common fish and shrimp species. Results showed the waste generation factor for fish and shrimp equal to 32.67 and 42%, respectively. The total quantity of fish-and shrimp-generated wastes in Bushehr province was estimated to be 29,388 tons per year, of which the quantity of generated waste by stores and by households was 3731 tons per year (16 ton per capita per year) and 8804 tons per year (34 kg per capita per year), respectively. The remaining quantity is related to other unaccounted sectors such as fish industries. Moreover, the biogas production potential from an anaerobic digestion were estimated 2,675,400 m 3 per year, which is equivalent to 16,052 MWh. In addition, the biodiesel production potential was obtained equivalent to 19 kt, which is about 4.2% of the total diesel fuel requirement of the province in 2016.

“…FW has a high content of potentially biodegradable components such as proteins and fats (Cadavid-Rodríguez et al 2019); therefore, FW is susceptible to be transformed into products such as low-value animal feed, biogas and organic acids. Biogas production from FW using Anaerobic digestion (AD) has been reported from commercial FW such as tuna, seabream and sturgeon (Eiroa et al 2012;Hadiyarto et al 2015;Greggio et al 2018). Recently, artisanal FW was proved as a suitable substrate to produce biogas.…”

In this research, operational parameters were assessed to optimise the production of volatile fatty acids (VFA) from artisanal fish waste (FW) using mixed-culture fermentation. The experiments were performed using a randomised block design with pH and Inoculum/Substrate (I/S) ratio as factors with three pH levels (5, 7 and 9) and five I/S ratios levels (0.20, 0.15, 0.10, 0.05, 0.00) with VFA production, total ammonia nitrogen (TAN), biogas and soluble chemical oxygen demand (sCOD) as response variables. The results indicated that pH and I/S ratio significantly influenced VFA production and the other variables evaluated. The highest VFA concentration (54.5 g/L) was obtained at pH 7 and with an I/S ratio of 0.05. These conditions were also optimal for TAN and sCOD. External pH control was proved as unnecessary as the highest VFA production (70.3 g VFA/L) was obtained without pH control. In these conditions, the fermentation broth was able to maintain its pH between 6.6 and 7.7. The VFA profile had acetic (35%) and butyric (32%) acids as the dominant species and propionic, iso-valeric and iso-butyric were minor species (< 10%). An economic assessment evaluating the establishment of a FW VFA biorefinery in Tumaco, Colombia was performed including capital, operational and labour cost, discounted payback period and cost curves. These results evidenced the potential of artisanal FW as a raw material for producing high concentrations of VFA and smooth the path for the establishment of a VFA and biogas biorefinery from FW.
