Methane production
Biogas is a methane-rich gas produced from the anaerobic digestion of organic waste. It is generated by the activity of anaerobic bacteria through a process involving four stages: liquefaction by hydrolytic enzymes, acid formation, methane formation, and methane production. The composition of biogas depends on factors like the raw material composition, temperature, and retention time. There are different modes of operating biogas plants, including batch, semi-continuous, and continuous systems. Yield and production of biogas are affected by parameters such as the quantity and type of organic matter, temperature, pH, and flow rate.

Anaerobic Digestion Presentazione Si
Anaerobic digestion is a series of microbiological processes that converts organic compounds to methane by four types of bacteria at different stages. The bacteria break down organic waste into sugars, amino acids, organic acids, and eventually methane and carbon dioxide. There are different types of digesters that operate at various temperatures and solid concentrations, including covered lagoons for large volumes of dilute waste, plug-flow for ruminant manure, and temperature-phased digesters for enhanced digestion of lignocellulose. Anaerobic digestion is important as it produces methane for energy, reduces greenhouse gases, and generates energy from waste.

IRJET- Production and Analysis of Biogas from Municipal Solid Waste
This document summarizes a study on the production and analysis of biogas from municipal solid waste. A biogas plant in Indore, India with a capacity of 20 tons per day was used to generate biogas from fruit and vegetable waste through anaerobic digestion. The plant produces approximately 2400 cubic meters of bio-CNG per day after purification. Various parameters like pH, temperature, and chemical oxygen demand were measured to understand their effects on methane formation. The pH of the inlet digester was maintained between 5-6 and the outlet between 6-7.66. The maximum biogas yield of 0.7527 cubic meters was obtained at a temperature of 35 degrees Celsius through anaerobic digestion.
Joseph et al 2015
The document discusses biodegradability and biomethane potential of vegetable, fruit, and oil fractions in anaerobic co-digestion. Laboratory experiments were conducted using anaerobic batch reactors to study co-digestion of vegetable and fruit waste with oil residue. Results showed that adding oil residue to vegetable and fruit waste increased methane yield by 30%. Oil could not be stabilized as a single substrate. Co-digesting vegetable, fruit, and oil fractions had higher methane yields than digesting them separately.
Biogas production
Biogas is produced through the anaerobic digestion of organic matter such as manure, food waste, and crops. It is comprised primarily of methane and carbon dioxide. The digestion occurs in anaerobic digesters, which are air-tight tanks that transform biomass into methane gas. This biogas can then be used as an energy source for heating, electricity, or transportation fuel after processing. Producing biogas also has environmental benefits as it manages waste and provides renewable energy.

Methane emissions from biogas plants - The Swedish voluntary agreement system...
Methane emissions from biogas plants are measured and reported through a Swedish voluntary agreement system. The system involves plants conducting monthly leak detection and external parties quantifying emissions every 3 years. Results from 2007-2012 show average methane losses of 1.5% at biogas production plants and 1.6% at gas upgrading plants. The voluntary agreement has helped plants improve, with some reducing losses significantly. However, the system has had limited impact on researchers and policymakers. Sustainability criteria for biogas as a vehicle fuel in Sweden are based on EU directives and involve meeting greenhouse gas savings thresholds. Default loss values from the voluntary agreement are used in calculations to meet these criteria.
Biometano: la versión renovable del gas natural

The document discusses the challenges with using digestate as a fertilizer. It notes that the inherent fertilizer value of digestate is modest, especially in the autumn, but that digestate can be more valuable than just the sum of its nutrients. However, waste-derived digestates are difficult to upgrade to increase their value. While digestate has some nutrient value as a fertilizer, this value is usually not enough to cover the costs of recovering and processing the digestate. Operators may need to upgrade digestate to guarantee having a market for it.

There are frequent accidents at anaerobic digestion plants during construction and operation due to gas explosions and exposure to toxic hydrogen sulfide gas. Many of these accidents are preventable through proper risk mitigation measures. During construction, risks can be reduced through adherence to the Construction Design and Management regulations, which require principal designers and careful attention to interfaces between equipment. During operation, permanent gas monitoring, confined space procedures, training, and permit-to-work programs can help protect workers from gas exposure. Incident reports show common risks involve maintenance activities, mixing of feedstocks, and overloading of digesters leading to gas release.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

- 1. BAT-Conclusion for AD Dipl.- Ing. David Wilken German Biogas Association Department: Waste, Fertilisation and Hygiene WT-BREF “Biological Treatment” 27th of March 2015, Seville
- 2. Digestate In line with European and national legislation, voluntary product specifications Digestate Application Separation Solid digestate Municipal, industrial, commercial, and agricultural biowaste Liquid digestate Liquid Application Direct Application (further upgrading possible) AD plant
- 3. Liquid digestateSeparated digestate Composted digestate Pelletised digestate Dried digestate Upgrading of the digestate Liquid Upgrading Pelletising CompostingDryingSeparation
- 4. Waste acceptance procedures • Choice of feedstock • Significant impact on the AD process • Quality and mixture can lead to higher biogas yield (nutrient & micronutrient supply) • Important for quality of digestate • Use as fertiliser according to national and European legislation • Clear procedures for acceptance and pre-acceptance • Description of every feedstock in the installation permit
- 5. Storage & handling of incoming waste • Storage of liquid and solid wastes • Material should be stored appropriately to its environmental risk • Liquid and semi-liquid waste should be stored in vessels, closed tanks, silos, bunkers etc. • Solid waste should be stored on impermeable surface, based on risk assessment (e.g. not necessary for woody material) • Preventing H2S exposure • Implementing a plan for the prevention, limiting, detection and control of unwanted chemical reactions (e.g. formation of H2S) • In particular for waste storage, mixing and pre-treatment areas, biogas production and storage, etc.
- 6. Process monitoring & control specific to AD • Process monitoring and control • To ensure stable reactor operation and to minimize operational difficulties • Process performance • Effective mixing , monitoring organic loading rate, pH, VFA’s and alkalinity • Measurement of temperature • Constant temperature in the correct range is very important for microbiological milieu, biogas production and digestate sanitation • Prevention of explosion and fire risks • Plan for prevention, detection and control of fire and explosion (ATEX) for waste storage, pre-treatment, biogas production and storage etc.
- 7. Emissions to water • Control of dry matter of the AD step • Adjust moisture content of incoming mixture in the AD step to run the process at the best conditions foreseen at the design of the process. • Reuse of waste water • From storage, pre- and post-treatment, side activities, surfaces etc. • To reduce total water consumption and amount of waste water • Application of solid and/or liquid digestate as fertiliser • Prevent or reduce emissions to water from AD plants • Digestate is valuable nutrient-rich fertiliser • Application according to national and European requirements
- 8. Emissions to air • Closed storage for not stabilized liquid digestate • Controlled transmission to aerobic phase for composting after AD • Implementing a leak-control on fugitive emissions • Minimizing sulphur emissions from combustion by adding metal salts, internal or external biological oxidation or activated carbon filtration • Additional biogas storage and/or alternative biogas consumer • As emergency case, biogas which cannot be stored or used energetically elsewhere should be flared by a gas flare.
- 9. Measures of energy efficiency and reduction of raw material consumption • Using biogas as energy source (e.g. in cogeneration, boilers, vehicles) • Biogas maximisation • Increasing energy efficiency of CHP • Using excess heat for external use to increase overall conversion efficiency (e.g. buildings, livestock rearing, drying processes) • Upgrading biogas to biomethane • Use of additives for optimizing AD process
- 10. • Depending on European and Local regulation, the produced digestate can be placed on the market to substitute inorganic fertiliser. • Establish and maintain quality controls over the digestate • Design and develop sampling and analysis protocols to determine suitability of the digestate to be applied to soil in safe environmental conditions according to national or European requirements.
