“…They found that lowering the digester temperature from 23-24 °C in summer months and to 13-14 °C in winter months resulted in a decrease of gas production by 23-37%. Kalia and Kanwar's (1998) study agrees with that of Alkhamis et al (2000), which indicates that heating the bio-digester to a temperature of about 35 °C is important for mesophilic bacteria growth and activity to obtain optimum biogas production. Martin and Khan (2016) conducted a study on the review of biogas digester technology in rural Bangladesh and one of the findings was on the impact of internal temperature on biogas production throughout the digestion process.…”

“…Researchers have widely focused on how temperature influences the production of biogas (Kalia and Kanwar, 1998;Pham et al, 2014;Alkhamis et al, 2000), irrespective of digester designs or installations. Dhaked et al (2010) stated that there are four temperature ranges for anaerobic digestion process: thermophilic temperature range (45-60 °C), mesophilic temperature range (30-40 °C) psychrotrophic temperature range (20-30 °C), and psychrophilic temperature range (< 20 °C.…”

“…In the poly-generation system considered solar thermal collectors are considered as complementary heat source for the digester (Axaopoulos et al, 2001), (Alkhamis et al, 2001). This heat feeds a thermal energy storage (TES), eventually integrated with heat produced by a biomass furnace, when the solar source is not sufficient.…”

The paradigm of the sustainable energy community is recognized as the future energy approach due to its economical, technical and environmental benefits. The analysed system is a waste-to-energy combined heat and power (CHP) generation plant that perfectly fits in the sustainable energy community paradigm. The power system is divided in the following sections: a) a mesophilic -single phase anaerobic digestion of Organic Fraction of Municipal Solid Waste for biogas production; b) a fuel treatment section with desulphurizer and pre-reformer units; c) a Solid Oxide Fuel Cell (SOFC) for CHP production; d) a solar collector integrated system(integrated storage system -ISS). An integrated TRNSYS/Aspen Plus model for simulating the power system behaviour during a typical reference period (day or year) was developed and presented. The proposed ISS consists of a solar collector integrated with storage systems system designed to continuously provide the thermal power required by the anaerobic digester.

“…Heating of a pilot or small-scale biogas reactor using solar water heating has been presented in detail (Alkhamis et al, 2000;El-Mashad et al, 2004a,b). This research presents an alternative way of using solar energy to heat biogas digester via the use of two greenhouses with the inlet greenhouse for heating the digester inlet surface.…”
