“…Biogas production from organic materials is dependent on substances that can decompose into CH4 and CO2. For this reason, the components of animal manure and energy plants and their decomposability are important parameters for methane production [4]. Crude protein, crude oil, fiber, cellulose, hemicellulose, starch and sugar are effective in the formation of methane.…”

In recent years, the need for alternative energy sources has become an urgent concern due to the decline in fossil fuel input and also the disruption of fossil fuels to cause global warming and waste management, which is a human problem. Biogas, an example of alternative energy, can be used to eliminate these problems related to fossil fuels and biodegradable waste management. Since ancient times, biodegradable waste has been the subject of the discovery of environmentally friendly fuel products such as biogas. Animal manure and urban solid wastes produced by humans are the leading ones among these wastes. In this study, anaerobic digestion of different ratios of cattle manure (CM) and municipal solid waste (MSW) was investigated. Anaerobic digestion studies untreated were carried out in mesophilic conditions. In the reactor where CM: MSW mixture ratio is 2: 1, the highest biogas production (222.5 ± 15.7 mL/g solid matter) was realized compared to other mixture ratios. NaOH pretreatments were applied to this mixing ratio with concentrations of 0.1, 0.5, 1 and 2 N in order to increase biogas yield. After NaOH 1N pretreatment, biogas production increased by 47.46% compared to the untreated reactor. As a result of the application of NaOH pretreatment with 2N value, due to possible rapid resolution, biogas production was decreased compared to 1N NaOH pretreated reactor. As a result of the study, it has been understood that CM and MSW can be a good mixture in anaerobic digestion and biogas production can be increased successfully with NaOH pretreatments.

 Anaerobic digestion was a good mix of fruit waste and chicken manure.  Thermal pretreatment was applied for biogas production.  The highest biogas production was 368 ml / g UK. Figure A. Anaerobic digestion of chicken manure and household waste Purpose: The aim of this study is to examine the effects of biogas production from different fruit wastes and fresh chicken manure mixtures after thermal pretreatment. Theory and Methods: Dry matter and organic matter analyzes was applied to chicken manure and fruit wastes. 20 types of bioreactors were used, each with 2 replicates. As a bioreactor, bottles 2-neck bottle with 500 mL were used. Outer surface heating temperature was 40 °C. The resulting gas volumes were determined by means of a 500 mL gas collection bag. Results: The highest yield was given as 215 mL biogas / g VS in the reactor with apple pulp: orange pulp: chicken manure mass ratio 1: 1: 3. In the anaerobic digestion process, production was slow for up to 9 days, but production accelerated after 9 days. This is because the inoculum is not used during the anaerobic process. In treated reactor, the maximum COD removal in this reactor was found to be 58 %. However, COD removal in the thermal pretreated reactor was 92.9%. Thermal pretreatments were applied only to the optimum mixing ratio Thermal pretreatments were performed for 100, 120 ºC for 30, 60 and 90 min.Biogas production efficiency increased among 32.4-71.1% as a result of thermal pretreatments applied at 100 and 120 ºC in 30-90 min intervals. SCOD removal ranged from 71.4% to 92.9%. The highest biogas yield occurred in 90 min application period under 120 ° C thermal pretreatment. Conclusion: In this context, as the application time of thermal pretreatments increased from 30 min to 60 min, it significantly increased the biogas yield at all temperatures. However, as the thermal pretreatment time increased from 60 min to 90 min, the yield increase decreased.

High organic carbon wastes can be used for biofuel production for reducing raw material costs. Green market wastes (GMW) are one of the raw material candidates to generate biofuel by fermentation with low-cost production and high yield of fuel formation. Biohydrogen and biomethane are potential gaseous energy sources that can be obtained through sequential fermentation of GMW. In this study, the ground and hydrolyzed GWM (a mixture of lettuce, parsley, spring onion, and dill) solid-liquid mixture was first valorized for biohydrogen, then the organic acid-rich residue of biohydrogen fermentation was subjected to biomethane production. Biohydrogen and biomethane was produced at mesophilic (37°C) and thermophilic (55°C) temperatures. The initial GWM amount varied between 1000-5000 g wb at mesophilic biohydrogen production. The highest cumulative hydrogen formation (CHF) and the rate were obtained at 5000 g wb as CHF=8.9 L and 916 mL H2 /L day, respectively. Thermophilic biohydrogen fermentation was conducted at 1000 and 5000 g wb and CHF reached to 14.2 L at 5000 g wb GMW. The yield of hydrogen formation was 1.6 times higher at thermophilic than that of mesophilic conditions. The residues from two fermentation temperatures of 5000 g wb GMW were used to produce biomethane under both fermentation conditions. Mesophilic and thermophilic conditions resulted in cumulative biomethane formations (CMFs) of 8.3 L and 5.8 L, and biomethane production yields of 0.17 mL CH4/g VFA and 0.13 mL CH4/g VFA, respectively. The findings revealed that GMW is a suitable substrate for efficient biohydrogen and biomethane production.
