“…The C/N ratio contributes to the efficiency of anaerobic digestion [32] by regulating microbial growth, by improving buffer capacity, and by providing process stability [33] (p. . The C/N ratio represents a very important factor in the production of a high level of biomethane, as this ratio indicates the degradation of organic matter by bacteria [34] (p. 135867), [35] (p. 621126).…”

The article presents comparative results from 5 categories of animals (4 samples originating from pigs, 2 from cows, 1 from chicken, 1 from ostriches, 1 from horses, samples quantified with A, B, C, D, E, F, G, H, I). These samples were collected from large, medium and small (family) farms. The results were validated by the biogas production generated by the respective samples, using the Automatic Methane Potential Test System (AMPTS II) bio-processor. The largest amounts of biogas (2,464.5 Nml, 2,262.0 Nml) were recorded for the samples from pig farms (Sample B and Sample D), whereas the lowest values were obtained in the case of Sample A (414.1 Nml) and Sample C (558.3 Nml). The heavy metals analyzed in the article are Zn, Cu, Fe, Mn, Ca, K, As. The results corroborate that the C/N ratio can also vary to values lower than 20-30, without affecting the biogas production process, and the heavy metal content must be known especially for the full management of the wastes. All final data presented in the article are based on repeated, triplicate experiments, with less as 2% deviation between data.

This study investigates the co-digestion of pressmud, a residue from sugarcane processing, and vegetable waste, with cow dung serving as the inoculum. The aim is to explore the potential of this tripartite mixture to enhance biogas production, streamline waste management, and contribute to sustainable energy generation. In recent years, the escalating concerns surrounding environmental sustainability and waste management have prompted significant research into innovative and eco-friendly approaches. Anaerobic co-digestion has a potential to enhance biogas yields beyond what is achievable with individual substrates. The complementary nature of diverse organic materials can stimulate microbial activity, leading to increased methane production. Additionally, co-digestion can alleviate challenges associated with certain substrates, such as the presence of inhibitory compounds or imbalanced nutrient ratios, by leveraging the compensatory attributes of other materials. The anaerobic co-digestion was carried out through the substrate and inoculum ration of 1:1. The digestion of pressmud and vegetable waste was carried out at different ratio of PM:VW (100:0, 70:30, 50:50, 30:70, 0:100) in one litre reagent bottle. The batch study was conducted for the period of 30 days. The methane gas was measured directly by passing the biogas into the alkaline solution by water displacement method. The effect of pH was noted throughout the study. Results shows that least methane yield was obtained in the ration 50:50 (PM: VW) and maximum methane yield was obtained in the 30:70 (PM: VW).

“…There are four types of bacteria: (i) hydrolytic (carbohydrate hydrolysis), (ii) acidogenic (monomeric components to organic acid), (iii) acetogenic and homoacetogenic (organic acid to acetic acid), and (iv) methanogenic (acetic acid to methane and carbon dioxide -methane production) [19][20][21][22]. However, various parameters including concentration of substrate, temperature, pH of the substrate, stirring speed, C/N ratio, and so on affect biogas production [23][24][25]. The existence of certain organic material has been suggested as a way to boost biogas generation [26][27][28].…”

In tropical areas, water hyacinth is one of the significant and large sources of biomass that can be used to produce biogas. The purpose of this strategy is to enhance sustainability, precise energy present, ease of transport, etc. of the original biofuel feedstock or to extract gases. In a semi batch digester, an experimental investigation on biomethanation of water hyacinth was carried out. Temperature, stirring speed and catalyst concentration affect the rate of biogas production. The catalyst has been discovered to primarily boost the rate of biogas production from water hyacinth. As the catalyst is used here to boost up the biomethanation reaction, the effect of catalyst in different kinetic parameters is investigated.
