BIO - GAS

Explain your idea in details:

Human action has triggered a vast cascade of environmental problems that now threaten the continued ability of both natural and human systems to flourish. Solving the critical environmental problems of global warming, water scarcity, pollution, and biodiversity loss are perhaps the greatest challenges of the 21st century. Will we rise to meet them? BIO-GAS is a renewable source of energy that involves the production of cheaper natural gas (Methane) from Biodegradable Waste for household use instead of the commonly used gas LPG liquefied petroleum gas. Its aim is to reduce the production of the greenhouse gas emission which is the main problem of our planet Earth that replaces methane with carbon dioxide. Biogas combustion results the total reduction in greenhouse gas emissions. Although it is a project for all but it is expensive to run. According to an article, The United States produces more than 70 million tons of organic waste each year. While feeding the hungry are necessary priorities for reducing needless food waste, organic wastes are numerous and extend to non-edible sources, including livestock manure, agriculture wastes, waste water, and inedible food wastes. When these wastes are improperly managed, they pose a significant risk to the environment and public health. Pathogens, chemicals, antibiotics, and nutrients present in wastes can contaminate surface and ground waters through runoff. Excess nutrients cause algal blooms, harm wildlife, and infect drinking water. Drinking water with high levels of nitrates is linked to hyperthyroidism and blue-baby syndrome. Municipal water utilities treat drinking water to remove nitrates, but it is costly. This is where the Bio-gas innovation comes in. All this wastes are collected and turned into methane and filled into gas cylinders and pipelines for household use without the production of carbon dioxide in the process and with this new innovation, the effect

Expected impact of your idea on sustainable development

Biogas systems turn the cost of waste management into a revenue opportunity for farms, dairies, and industries. Converting waste into electricity, heat, or vehicle fuel provides a renewable source of energy that can reduce dependence on foreign oil imports, reduce greenhouse gas emissions, improve environmental quality, and increase local jobs. Biogas systems also provide an opportunity to recycle nutrients in the food supply, reducing the need for both petrochemical and mined fertilizers. The gas used at home in gas cylinders is LPG which is either propane or butane while Bio-gas is natural gas (mains gas) or CNG which are methane. Propane, butane and natural gas are all hydrocarbon gases but Propane and Butane falls under the broad label of LPG, as liquefied petroleum gases while Bio-gas is CNG Compressed Natural Gas (methane). The major difference between CNG and LPG is that CNG storage pressures can be more than 10x that of LPG. For example, LPG pressure is less than 20MPa whilst CNG is between 20 and 25MPa. After biogas is captured, it can produce heat and electricity for use in engines, microturbines, and fuel cells. Biogas can also be upgraded into biomethane, also called renewable natural gas or RNG, and injected into natural gas pipelines or used as a vehicle fuel. Stored biogas can provide a clean, renewable, and reliable source of baseload power in place of coal or natural gas. Biogas can also be used as a source of peak power that can be rapidly ramped up.

Plans for implementation and sustainability

Waste materials are collected from spoiled food from shops, biowaste generated by consumers, sludge from wastewater treatment plants and manure. The material is typically delivered to the biogas plant's reception pit by lorry or waste management vehicle. They are processed in anaerobic digesters as a liquid or as slurry mixed with water. The waste is taken to a waste treatment facility where it is used to generate heat and electricity. Anaerobic digesters are generally composed of a feedstock source holder, a digestion tank, a biogas recovery unit, and heat exchangers to maintain the temperature necessary for bacterial digestion. The mass is pumped into the main reactor where biogas production takes place. Then microbes feed on the organic matter, such as proteins, carbohydrates and lipids, and their digestion turns these into methane and carbon dioxide. Microbes need warm conditions, so the biowaste is heated to around 35°C. Most of the organic matter is broken down into biogas a mixture of methane and carbon dioxide in approximately three weeks. In the final stage, the gas is upgraded by removing impurities and carbon dioxide. After this, the biogas is ready for use by enterprises and consumers. Air-To-Ground Surveillance Target Acquisition Radar is a joint program between the EPA, USDA, and DOE. The program promotes the use of anaerobic digesters on livestock farms to reduce methane emissions from animal waste. The program supports the planning and implementation of anaerobic digester projects, and includes state and non-governmental partners which can help in the financing of the project.

Your profile

My name is Majeogbe Paul, a Nigerian citizen; owner of the Biogas Idea for the reduction of greenhouse gas emission. I am 19 years old and I reside in Ibadan, Oyo State, Nigeria. My Senior Secondary schooling was at Wesley College of Science, Elekuro, Ibadan. Presently I am studying my Diploma in Computer Science at the Polytechnic, Ibadan. Although this project is far from my field, Computer Science is to solve the global problems technologically but the concept behind this idea is while schooling at Wesley College, I met a Corper serving in my school but also running his Masters Degree at the great citadel of learning; University of Ibadan as a Mechanical Engineer. The project given to him was to make a Bio-gas, being a closer friend to him; he started asking me how it has ever crossed my mind turning all waste in my school (which is a boarding school) into wealth. From there he created a Forum called WASTE TO WEALTH. From the forum we made useful things used in school and by the student from cork (we have a School Hall used for parties), broken kegs (used by student for fetching water), used papers etc. From this idea, then I understood what my teacher meant. He completed his project making use of leftover foods from the school dining hall, poultry and piggery farm. Since then I made up my mind I must never let this ideal go dead but do something that will help my family and my country as a whole.
