Biogas is a promising renewable energy resource produced by using anaerobic digestion of organic substrates and it is mainly used to generate electricity by means of biogas engines. Other potential utilisations are growing, e.g. grid injection and biofuels production but, generally, a treatment aimed to increase its quality is mandatory and greater investments are generally required to produce upgraded biogas (biomethane). Despite the increasing of interest on these applications, a lack of information is still present from an economic point of view. The present paper performs an extended economic assessment of upgrading and selling biogas starting from a typical farm-based anaerobic digestion plant in Northern Ireland assumed as reference. Several economic indexes have been considered to assess the economic performance of the upgraded anaerobic digestion plant, namely net present value, pay-back period, profitability index and internal rate of return. Moreover, different scenarios in terms of fossil fuel prices have been analysed. The results show that producing and selling biomethane can be economically feasible if an adequate market is fostered. Optimum anaerobic digestion sizes between 26.9 and 64.4 tonne/y have been found, with correspondent net present value and pay-back period values in the range of £6.7–64.4M and 2.8–7.5 years, respectively, depending on the price scenarios analysed and the economic index chosen. Generally, adopting the net present value as objective function of the optimisation leads to greater anaerobic digestion size than the other indexes for any price scenarios considered. Finally, tougher market conditions (i.e. higher fossil fuel prices) lead to better economic performances of the upgraded anaerobic digestion configuration.

“…With regard to finance, authors such as Hes et al (2017) assert the importance of knowing investments and microcredit. They depict the related reality in Sri Lanka, dispelling the existing doubts about the potential of commercial microcredit as a strategic vehicle for the implementation of small-scale biogas plants.…”

Faced with the increasing demand for renewable energy, researchers have developed several ways to generate them, such as biogas. Thus, the present study aims to demonstrate the economic viability of electricity generation from biodigesters in a pig farm to contribute to sustainable development by reducing pollution in the environment. Studies focused on biomass derived from pig waste are still scarce. Moreover, one of the motivations of the present study is the fact that Brazil is a major producer and exporter of pig meat, with most of the production taking place in the south and southeast regions. The methodology used is defined as exploratory, descriptive, explanatory, and applied. The scientific procedures were documentary and bibliographic research, case study, and cost analysis. An economic management model was developed using financial management instruments such as cash flow, internal rate of return, and simple and discounted payback, confirming the economic viability of the investment made for generating energy from animal biomass produced in a pig farm located in the interior of Rio Grande do Sul.

“…In the past decade, nations have moved towards renewable energy sources to fulfil their energy requirements (Li 2018). In recent years, renewable energy sources have gained importance due to the abundance of available raw materials, access in remote areas, control of environmental pollution, good performance, reduction of biomass waste, energy transfer, and low costs (Hes et al 2017;Kannah et al 2017;Ravi et al 2018). Due to the increase in population, industrial development, and great dependence on fossil fuels for their energy needs, Pakistan has faced serious energy crises during last decade (Zuberi et al 2015).…”

Anaerobic co-digestion (AD) of Cynodon dactylon grass and cow dung was conducted with four different composition levels. To increase lignocellulose digestibility and methane yield, grass was pretreated with NaOH and thermally-modified bentonite was used to inhibit the ammonia production. The highest cumulative methane yield obtained from treatments C (0.40:0.60), D (0.60:0.40), and B (0.20:0.80) was 427 mL/ g.VS, 333 mL/g.VS, and 303 mL/g.VS, respectively, over a digestion period of 40 days at a mesophilic temperature. Treatment C showed an 89.7% increase in the methane yield with respect to the control, followed by treatment D, which recorded a 48% increase, and treatment B at a 34.6% increase. A modified Gompertz model was used to explain the methane generation scenario. The process stability parameters of the anaerobic co-digestion system, such as pH, chemical oxygen demand (COD), electrical conductivity (EC), total solids, total and free ammonia contents, and volatile solids removal were explained in depth in this study.
