Bio digester Technology
Bio digester technology is a system that employs microbes to biologically degrade organic materials or waste through aerobic or anaerobic processes. Human waste. Can be processed using a bio-digester. Anaerobic and Aerobic Bio digester Technology Anaerobic bio digester technology is used to break down organic wastes. The key feature of this system is that waste decomposition takes place in the absence of oxygen.
The major benefit of using anaerobic bio digesters is that you can produce biogas using the by-product methane, which in turn, can be used to generate electricity or heat. It can be used as an eco-friendly and renewable source of energy in place of fossil fuels.
Bio digester Technology in Bio Toilets
A portable toilet generally consists of a toilet seat, a holding tank and a formulation assisting waste decomposition. However, bio-toilet consists of a bio digester tank made generally of FRP, UPVC or galvanized iron. The closed container contains a special anaerobic microbial consortium that helps in the degradation of human waste reaching the tank. Harmless by-products such as carbon dioxide, water and methane are generated after the decomposition process, which can be used to produce biogas.
Bioclean BD for Fecal Sludge Management bioclean-bd Benefits of Bio digester Technology There are several benefits of using bio digester technology based bio-toilets over conventional toilets. Biodigester based mobile toilets, due to their compact size, can be installed at geographical terrains where conventional toilets can’t be used. The cost is comparatively low as well. Bio-digester bio-toilets are eco-friendly since no harmful by-products are produced. Instead, the byproduct produced can be used as an energy resource.

Methane capture, the process of using the decomposition of livestock byproducts like cow and hog manure to generate electricity, is a promising technology. It helps to resolve existing, and for the time being, necessary evils such as climate-warming methane emissions from cattle and pigs. It works by exposing the livestock waste to bacteria and enzymes that break down the embedded methane into usable natural gas that can be pumped right into generators.
In anaerobic processes the rate-limiting steps are the hydrolysis conversion rate and the soluble substrate utilization rate of methanogenesis. The hydrolysis of colloidal and solid particles does not affect the process operation and stability but does affect the total amount of solids converted. When anaerobic digestion processes are used for municipal waste sludge treatment, more than 30 days detention time is usually needed to fully convert the solids. The soluble substrate utilization kinetics is critical to maintaining a stable anaerobic process.

How do you absorb methane gas?
Image result for methane recapture devicesA team of researchers at MIT has come up with a promising approach to controlling methane emissions and removing it from the air, using an inexpensive and abundant type of clay called zeolite. In this image, the zeolite, depicted as the complex structure in the middle, absorbs the methane

DescriptionMethane is a prevalent manmade greenhouse gas that traps 28 times more heat than carbon dioxide (CO2). Reducing methane emissions by recovering and using methane as a clean energy source offers many benefits for the environment and local communities. This video highlights the many ways that reducing methane can benefit the environment and local communities.
Importance of Methane
GMI created a Methane Mitigation Matters video series to explain the role of methane in climate change and provide an overview of the biogas, coal mine, and oil & gas sectors.
Methane Mitigation Matters Video SeriesMethane (CH4) is a hydrocarbon that is a primary component of natural gas. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth’s temperature and climate system. Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources. Anthropogenic emission sources include landfills, oil and natural gas systems, agricultural activities, coal mining, stationary and mobile combustion, wastewater treatment, and certain industrial processes.
Methane is the second most abundant anthropogenic GHG after carbon dioxide (CO2), accounting for about 20 percent of global emissions. Methane is more than 25 times as potent as carbon dioxide at trapping heat in the atmosphere. Over the last two centuries, methane concentrations in the atmosphere have more than doubled, largely due to human-related activities. Because methane is both a powerful greenhouse gas and short-lived compared to carbon dioxide, achieving significant reductions would have a rapid and significant effect on atmospheric warming potential.
Visit EPA's Methane page for detailed information about sources of methane, trends, and projections of future methane emissionsRead GMI's fact sheet, Global Methane Emissions and Mitigation Opportunities Other Things to Know About Methane EmissionsWho are the biggest methane emitters?China, the United States, Russia, India, Brazil, Indonesia, Nigeria, and Mexico are estimated to be responsible for nearly half of all anthropogenic methane emissions. The major methane emission sources for these countries vary greatly. For example, a key source of methane emissions in China is coal production, whereas Russia emits most of its methane from natural gas and oil systems. The largest sources of methane emissions from human activities in the United States are oil and gas systems, livestock enteric fermentation, and landfills.
Why aren’t efforts to capture and profitably use methane emissions more widespread?Despite multiple benefits, methane recovery is not widespread for several reasons.
Methane is generally a secondary byproduct in the industrial processes from which it is emitted. Coal mines, for example, seek to vent methane from the mine workings because it can cause explosions. Historically, mining companies have not viewed the associated methane as an energy resource in its own right.Those responsible for the emissions may not be familiar with the technologies available for methane recovery or the potential for profitable recovery projects. This is especially true in developing countries where improved access to information and technical training would be beneficial to generating support for methane recovery projects.Poorly functioning energy markets and financially insolvent utilities and municipalities within many countries fail to provide the private sector with a climate that will attract their investment in projects to capture and utilize methane.
