Bio Gas from Spent Wash

Waste treatment in London is not very energy-efficient or economical which is a cause for high taxes. An interesting alternative, in addition to recycling, is for household waste to be burned or converted to biogas to be used as a source of energy which can provide thousands of households with heat and electricity [13][14].

The renewable energy that the Georges produced through the bio-gas is set up to offset the farm's electricity use and/or sell the power at wholesale rates to the local utility. In the article it stated that the change to bio-gas results in less odor-causing compounds in manure in a liquid storage system and the breaking down of manure in the digester changes the organic nitrogen into ammonium which is when spread on the fields it’ll become more readily available when consumed by the plants allowing for less nutrient runoff. Also reduces weeds appearing in the fields causing less weeds growing with crops. Another great thing about the digestion process it also reduces methane, a greenhouse gas, emissions (basically global warming) which would otherwise remain in the atmosphere for 9 to 15

Identified wastes in the current processes using the seven wastes as a guide to what should be looked for. The question was asked, “Why did this waste occur?” and, “What can be done to prevent it?”.

Fracking drills into the earth in order to obtain gas. However, in the process methane is leaked into the environment hurting the climate. When cows digest food, they too emit methane in their waste and their flatus. Cattle emits “one hundred and fifty billion gallons of methane per day and produces one hundred and thirty times more waste than all humans collectively”. Unlike human waste, most of it has no use and cannot be used for “waste treatment”.

First, reduction of GHG, carbon capture and sequestration. Reduction of GHG is one of the most challenging tasks currently facing by the world scientists. Although a minor reduction process has been succeeded but they were used synthetic chemicals, which are in fact not good for environment. In consideration of this realism for protecting the future, my research will be focused to reduce GHG by developing new technologies on the biological mechanisms and without using any chemicals (Fig. ---). As I mentioned above (patent pending), I have already succeeded to reduce GHG up to 12%. In this long term project, I have targeted to clean the air 100% by reducing the harmful anthropogenic GHG as necessary. In this aspect, Carbon capture and sequestration is a very potent technique. Following this approach, carbon dioxide or other forms of carbon will be processed for a long-term storage. This process will be focused to capture CO2 by mimicking nature’s process for hardening tissues in living organisms. This is a similar biological process of corals and other calcifying organisms (ref--). However, here I would use a newly discovered group of microbes (described in the patent). In this technique, CO2 will be used as a potential beneficial material to produce highly useful products such as beneficial mineral for human health (fig--). In addition, some natural material (following the patent Aqua-NOF-GHG with some modification) will be used on carbon capture in

For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.

In some parts of the world, human waste is being used as agricultural fertilizer and it is known as biosolids. We have biosolids due to the wastewater treatment process. There are many advantages and disadvantages to the use of biosolids, however, I believe the advantages outweigh the disadvantages. Biosolids create job opportunities, promote farming, is free and is a cost effective of disposal. Using biosolids can cause odours in the area and may affect health as well. Although biosolids can cause odour problems, farmers see it as a free source of fertilizer. It helps produce ample crops. Creating biosolids is a form of recycling which prevents humans from dumping it in landfills. Biosolids have been

A good example is the design created by Leroy Mwasaru and his classmates. While more large-scale systems are being used on big livestock farm operations in the U.S. and other countries, efficient and inexpensive ways to create biogas can be tricky in places where energy is most needed and money and resources are most scarce. It's a worldwide challenge to come up with new and improved ways to turn waste into energy!

In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.

Unlike gasoline or diesel, biofuels release little pollution. It can also be used to produce electricity by heating water using biofuels and using the steam produced to rotate a turbine. Another method is to allow the biofuel to decay and produce methane. Methane is commonly used as fuel for car, heating, cooking, and producing electricity.

Again, much like other small hydro projects, there is a rack at the inlet of the penstock to prevent debris from entering. However, these projects are somewhat unique in their approach to disposing of this waste. All biowaste is used to make compost, while all plastic bottles and de- bris are recycled [6]. Additionally, the

Biogas is a mixture essentially comprising mostly methane (CH4, around 55-75%) but also contains carbon dioxide (CO2, around 25-30%), varying quantities of water (H2O) and hydrogen sulphide (H2S). The thermal energy available from the methane contained in biogas is about 6 to 8 kWh/m3. This corresponds to half a litre of diesel oil and 5.5 kg of firewood [21].

For this project I am doing biogas, most farmers in Uganda don’t make use of the animal waste to generate energy for their household use. Having a biogas digester would give farmers power which they can use for lighting and cooking. The digester produces bio-slurry which serves as organic manure for their crops. Therefore biogas would be the most efficient and accessible form of energy in the rural areas which constitute 80% of the population of Uganda since the animal waste is available to them at no financial cost.

There are an abundance of sources of energy and fuels in our country and natural gas is one of them. The attribute of natural gas that separates it from the other fuels and makes it distinct is that even though it is a non-renewable source of energy it is found in abundance and can last for centuries and its usage results in much lesser pollution compared to other fuels. In India there is huge potential for natural gas and most of this potential is yet to be exploited. In context of rapidly dwindling quantities of fossil fuels natural gas began to gain prominence as sooner or later everyone has to turn to natural gas after these other fossil fuels get completely exhausted.
