Organic processing is the process of breaking down organic matter into its components to create useful products. Anaerobic digestion is a type of organic processing that is used to convert organic matter into energy-rich fuels, such as methane. The performance of anaerobic digestion can be affected by various factors, such as the chemical composition of the substrate, the conditions of the process (such as temperature and pH), and the type and number of microorganisms present. To improve the performance of anaerobic digestion, various treatment methodologies have been developed. Mechanical treatments, such as grinding and size reduction, increase the surface area of the substrate and improve the accessibility of the microorganisms to the organic matter. Thermal treatments, such as heating the substrate, can kill pathogens and increase the solubility of certain compounds. Chemical treatments, such as the addition of acids or alkalis, can change the pH of the substrate and affect the activity of the microorganisms. Biological treatments, such as the addition of specific microorganisms or enzymes to the substrate, can increase the activity of certain groups of microorganisms or break down specific compounds. Ultrasonic and microwave treatments can change the physical properties of the substrate and make it more accessible to microorganisms. While the treatment of substrate can be a technique to improve the digestion performance and increase the methane yield, the impact of treatment on the environment and the cost of the treatment should also be considered before implementation. This is why it is important to weigh the pros and cons of each treatment method carefully before implementing it. With the right treatment strategy, organic processing can be used to create energy-rich fuels in an environmentally friendly and cost-effective manner. The transportation cost and competition with inorganic chemical fertilizers are the major constraints to the success of composting as a waste management option. However, the various steps that are taken to improve the market value of the compost – such as drying, screening, and granulating or pelletizing – have the potential to make composting a more attractive option. Composting offers many benefits over other waste management options, such as reducing the volume of waste and environmental pollution, and providing a valuable product that can be used to improve soil quality. Additionally, it is more environmentally friendly and cost-effective than other methods, making it a great way to reduce the amount of waste sent to landfills and create useful products. With the right treatment strategy, composting can be used to reduce the amount of waste created and improve the environment. The final stage of the biogas production process is the Methanogenesis reaction, which occurs when methanogens convert acetic acid and other compounds into methane and carbon dioxide. During this reaction, the methanogenic bacteria convert molecular oxygen into molecular hydrogen and molecular carbon dioxide, releasing methane as a byproduct. The methane produced in the Methanogenesis reaction can then be collected and compressed into compressed biogas (CBG). CBG is a valuable product that can be used in a variety of applications. It can be used as a fuel in vehicles, as a substitute for natural gas, and as a source of energy for power generation. Additionally, CBG is a renewable energy source, making it an attractive option for many industries.
