“…The properties of the feedstock were calculated based on a statistical analysis, following the methodology described in our previous work [27]. Briefly, the results from extended Weende analysis of selected types of raw materials [30][31][32][33] were used to calculate the overall feeding value of biomass (X c ) and of the four fractioning factors (proteins, lipids, carbohydrates, and inert fraction). The summary of the basic configuration is presented in Table 4.…”

Background Increasing the efficiency of the biogas production process is possible by modifying the technological installations of the biogas plant. In this study, specific solutions based on a mathematical model that lead to favorable results were proposed. Three configurations were considered: classical anaerobic digestion (AD) and its two modifications, two-phase AD (TPAD) and autogenerative high-pressure digestion (AHPD). The model has been validated based on measurements from a biogas plant located in Poland. Afterward, the TPAD and AHPD concepts were numerically tested for the same volume and feeding conditions. Results The TPAD system increased the overall biogas production from 9.06 to 9.59%, depending on the feedstock composition, while the content of methane was slightly lower in the whole production chain. On the other hand, the AHPD provided the best purity of the produced fuel, in which a methane content value of 82.13% was reached. At the same time, the overpressure leads to a decrease of around 7.5% in the volumetric production efficiency. The study indicated that the dilution of maize silage with pig manure, instead of water, can have significant benefits in the selected configurations. The content of pig slurry strengthens the impact of the selected process modifications—in the first case, by increasing the production efficiency, and in the second, by improving the methane content in the biogas. Conclusions The proposed mathematical model of the AD process proved to be a valuable tool for the description and design of biogas plant. The analysis shows that the overall impact of the presented process modifications is mutually opposite. The feedstock composition has a moderate and unsteady impact on the production profile, in the tested modifications. The dilution with pig manure, instead of water, leads to a slightly better efficiency in the classical configuration. For the TPAD process, the trend is very similar, but the AHPD biogas plant indicates a reverse tendency. Overall, the recommendation from this article is to use the AHPD concept if the composition of the biogas is the most important. In the case in which the performance is the most important factor, it is favorable to use the TPAD configuration.

“…Whatever the raw material for biogas, the influencing factors are the same. Because the biogas production base is biologically, these factors are the same as the factors that influence the growth of anaerobic bacteria, including C/N ratio, total solid (TS), pH, temperature, alkalinity, F/M ratio [26,27], [36][37][38], [28][29][30][31][32][33][34][35].…”

Increased rice production in Indonesia not only brings good news socially and economically, but also brings bad news for environmental ecology. In each rice crop produces 50% rice straw and 50% grain. The grain is divided into two again, namely 80% rice and 20% rice husk. In 2018, counted the rice husk up to 10,379,625 tons, a fantastic number if cannot be managed properly so that it can pollute the environment. One alternative to deal with the high rice husk is through conversion to biogas. Biogas is an energy that is formed under anaerobic conditions with organic material so that it is also called renewable energy. The development of research on biogas production from rice husks based SS-AD has experienced a positive increase in hardness. Studies have been conducted on the pre-treatment to other influencing factors. But after the authors describe the latest development of biogas research from rice husk, there are still some variables that have not been tested such as physical treatment, the influence of temperature, pH and alkalinity. Based on this review, further research is needed to complete a number of variables that have not been carried out so that it is expected that the development of biogas production from rice husk based SS-AD can move toward larger scales such as pilot scale and industrial scale.

“…The estimate volume of biogas produced per day was calculated with base on the studies previously made and with data supplied from the company. The effluent from slaughterhouses is characterized for having a COD between 580 and 3750 mg/L and about 0.63% of dissolved solids [5,7].…”

The process of anaerobic digestion generates biogas filled with CH4, this gas may be harnessed to produce electricity, heating and even used to produce biofuel. An evaluation of the economic viability of the implementation of a digestion unit was done, by applying this principle at a slaughterhouse in Alto Alentejo. The project was scaled to process about 151.000 m3/year, it has an estimated cost of over 337.000 euros. The evaluation was made with an investment from the company itself, investment programs and with recycling of the heat, obtaining a return on investment period of 10, 6 and 2 years respectively.
