“…By using its built-in features to perform a TEA, it is possible to identify cost-sensible factors during the technological development and implementation stages. The above was supported by the results, showing that a vinasse-fed AD plant in Colombia is economically feasible when the processing flow rate is >25 m 3 /h, which corresponds with previous studies performed using ASPEN Plus ® and Excel ® [49][50][51][54][55][56][57]. Taking into account that the vinasse flow rates produced by Colombian distilleries are below the mentioned threshold, we proposed joining vinasse-waste streams to overcome the flow rate limitation.…”

“…Siddique and collaborators [49] indicated that an optimum flow rate during the AD process is a critical point for the design and management of an AD plant. The processing flow rate affected two important parameters: biogas and methane yield and energy assessment.…”

“…Thus, the amount of produced biomethane has a strong impact on the energy balance and economic feasibility of an AD plant [50]. Other researchers have reported additional factors that affect the economic feasibility of implementing an AD plant, such as energy capacity and operating cost, which varies according to the country's economic conditions [44,[49][50][51].…”

SuperPro Designer® is a process simulator software used for analyzing the techno-economic feasibility of large-scale bioprocesses. Its predetermined built-in features allow for easy implementation by non-experts, but a lack of examples limits its appropriation. This study aims to validate the implementation of SuperPro Designer® by non-experts for the techno-economic analysis of anaerobic digestion in Colombia, using vinasse as feedstock. These results demonstrate the financial feasibility of such a process when a processing flow rate of 25 m3/h is ensured. Additionally, this study validates the manageability of the tool for assessing the economic feasibility of a technology, a key practice during technology development regardless of the area of expertise.

“…During petrochemical wastewater anaerobic digestion, huge amount of volatile fatty acid is produced which is inhibitory to methane production [4]. A few investigations have exhibited that cofermentation of food waste with petrochemical waste-water may keep up ideal pH and increase biogas generation [5], yet the ideal substrate proportion and the hypothetical gas generation varies in every particular case.…”

The valorization of agro-modern waste through anaerobic codigestion signifies a remarkable prospect for waste treatment and sustainable energy source generation. This study intended to improve the codigestion of food waste and petrochemical wastewater by an advanced two-phase process. In view of concentric acidogenic and methanogenic stages, intended for upgrading execution and diminishing pollution. The ideal food waste to petrochemical wastewater proportion was assessed under batch operations. From that point, codigestion was carried out by continuous feeding operations weighting single-and two-phase digestions. The outcomes exhibited that the supplementation of petrochemical wastewater in codigestion with food waste incredibly improved the anaerobic system. The maximum methane generation was acquired codigesting the two wastes at equivalent proportion by utilizing the creative two-phase system. The proposed framework achieved the highest methane production of 259 mL/g volatile solid, which is more than double than the single-phase system and 11 % greater than that of conventional two-phase system.

“…For this reason, several studies have evaluated the anaerobic process for the treatment of organic substrates. In particular, for higher generation of bioenergy, recent studies have focused on codigestion: the simultaneous anaerobic digestion of different organic substrates in a single digester (Siddique et al, 2015). The use of multiple cosubstrates can improve methane production because of proper interactions in the bioreactor (Siddique et al, 2014).…”

The codigestion of different wastes is a promising concept to improve methane generation during anaerobic processes. However, the anaerobic codigestion of catering waste leachate with algal biomass and sewage sludge has not been studied to date. The present study investigated methane generation by the anaerobic codigestion of different mixtures of catering waste leachate, microalgal biomass, and sewage sludge. Codigestion of waste mixture containing equal ratios of three substrates had 39.31% higher methane yield than anaerobic digestion of raw sludge. This was possibly because of a proliferation of methanogens during the codigestion period, induced by multiphase digestion of different wastes with different degrees of digestibility. Therefore, codigestion of catering waste leachate, microalgal biomass, and sewage sludge appears to be an efficient technology for energy conversion from waste resources. The scientific application of this codigestion technology with these three substrates may play a role in solving important environmental issues of waste management.
