Imagine eating food that was cooked using natural gas generated from your own human waste. The collected Feces is then converted into combustible "biogas," or methane gas that can be used for cooking. It has reduced by 60 percent the annual wood-fuel costs. Prior to the construction of blob center, some human waste was being thrown down the hill, near natural bodies of water such as Lake Nassau. The process requires putting a given amount of human or other animal waste into a "digester," which ferments it using bacteria to release methane gas that can be captured and then burned as fuel.

While waste smells bad initially, the biogas that is produced has no foul odor. Once the methane is produced, the remaining waste can be used as an odor-free fertilizer. This project has also improved people's lifestyle and living standards by giving them loans to build good houses. The project has sensitizes the Importance of harvesting rainwater. GILLIAN COMMUNITY WATER PROJECT.

Practical Action together with ANYWAYS (Nassau Water and Sanitation Company) started a community water based project to ensure the people In the Informal settlement of Nassau access safe and clean water for life.This project has centralized water service delivery through the delegated management model for water provision in partnership with ANYWAYS. The company supplies water in bulk to community groups who in turn supply water to end users through water chambers, water kiosks and individual households. In this model the water company regulates the water prices and it bills the community groups as they bill the consumers. The Gillian Community Water Project buys water In bulk from ANYWAYS at 100,com for SSH. 35/- They then supply at a price of SSH.

2/- for tresses The abode people go round selling the water at SSH. /- for 20 liters There is also a Prepaid Water Meter,this allows -rationing of water -reduces water wastage SST. JOSEPHS ENVIRONMENTAL GROUP. This group collects solid wastes from Shabby, Coinage, Kendal and September. They have been funded by Comic Relief U.

K and have one lorry that collects the soil wastes and takes it to Got dumping site. This has created employment for the youths at the same time ensuring the community lives at a clean and safer environment. COMPOSTING TOILETS AT CRATER VIEW SECONDARY SCHOOL. The modern day sewer system has failed.

Sewage overflows cause beach closures, bread illnesses, and contaminate the environment. And this is happening in place that actually have sewage treatment...

Most of the world does not and untreated sewage more quickly contaminates the environment, and is the source of illness an death for millions of people, a child dies every 21 seconds as a result of inadequate sanitation (EUNICE, WHO 2009) Fortunately, we don't need costly sewage plants or septic systems to render human waste into a harmless substance that, instead of being a problem, is a solution to problems of water shortages, water pollution, and reliance on chemical fertilizers.This is ecological sanitation, taking care of our human sanitation needs in a way that is helpful, rather than harmful, to the environment. Through nutrient cycles, we are intrinsically and symbiotically connected to plants: we eat plant foods, and plants turn the nutrients we excrete back into food. This is known as a closed loop system. In the industrial world, most such natural cycles ha long been broken.

Ecological sanitation closes the loop. Composting and dry toilets use natural processes to turn human excreta into a valuable soil amendment.They typically use no water, or very little water in immemorial scale applications. Potential pathogens are killed by a variety of processes, including die-off and predation by other microorganisms. To have a well functioning composting toilet the following should be kept in mind.

On a broader scale, ecological sanitation manages sewage by drastically reducing water consumption through conservation, rainwater catchments, and on-site greater and seawater recycling. Ecological toilets give eating and pooping a nee importance. To take care of our bodies and their functions we no longer need to harm the earth.Instead of participating in a system that wastes precious resources, e can be making rich humus and fertilizer each day.

We can live our lives knowing that we contribute valuable nutrients to the earth, that we use them in our yards an community gardens and help plants grow. Contact from people, until it is fully composted and safe to handle. Ventilation: The toilet needs a flow of fresh air, to add oxygen and remove odors. All vents should exit the living space.

Moisture: A composting toilet should not be wet, sawdust soaks up urine, or urine is diverted away from the feces.If the toilet does not divert the urine, or if a small amount of water is added, the material will need more dry material deed or extra heating and mechanical mixing. Temperature and time: The rate of decomposition is a combination of temperature and time: the hotter the compost pile, the more quickly the process happens, or if the pile is not hot, the longer it takes. At Crater View Secondary School the compost is left for six months. Bulking agent: In a composting toilet sawdust covers the material creating air gaps for aerobic bacteria to break down the material.Toilet paper and feces compost through the same process a household food scrap compost bin undergoes.

In a dry toilet ash r lime is mixed with soil and added to create a dehydrating environment for breakdown and die off of pathogens. Dry toilets are often used in arid, dry climates where lime and ash are more available than sawdust. Challenges faced by the school. -Sanitary towels accidentally thrown to a dry toilet. -Dry toilet-adds mix of ash and soil but some students may urinate there. -Handling of these feces is unhygienic.

Feces are typically stored for a minimum of one year before being used as fertilizer.Urine diversion. Urine diversion can address problems associated with too much liquid and odor from poorly functioning toilet. They also facilitate easy collection of urine, a valuable nitrogen fertilizer. It's a urine diverting toilet collects urine,so it has two containers to manage (urine and feces).

Since urine diverting toilets take a little getting used to, they are not typically a good option for public toilets hence used in Crater View Secondary School where the students can be guided and instructed on the proper usage of it.Urine Fertilizer Collecting urine, that magical yellow liquid we excrete from our bodies several times a day, is an easy way to recycle human nutrients. Urine contains most of the nitrogen, phosphorus and potassium we release. These nutrients are the major components of chemical fertilizers, and urine is an amazing plant fertilizer.

To collect urine,alt must be fitted with a tight cover to prevent oxygen from turning the urine's nitrogen into ammonia, which smells bad and causes some nitrogen loss. Though urine is usually sterile, it can become contaminated if it comes into contact with feces.There are also a few diseases that can be transmitted through urine: lepidopterist and sadomasochists (bilharzias), which are found almost exclusively in replica aquatic environments; and typhoid, which is inactivated shortly after excretion. If urine has been contaminated with feces, or if it came from strangers Urine is easy to purify, all you have to do is wait.

Urine leaves the body fairly acidic and then the pH increases rapidly until pathogens are unable to survive. This process takes from fifteen days in warmer places to over six months in the chilly winter regions.How to use urine: Dilute it--one part urine to three to six parts water--and pour it into the soil around your plants. Don't use on young seedlings, and water alternately with rainwater or itty water to flush salts from the soil, or apply urine before a rain.

Compost it! Pour urine (rich in nitrogen) onto sawdust, leaves, or other carbon-rich materials and let it rot. Add it to your greater system or constructed wetland. Divert it to a mulch filled basin near nitrogen loving plants. Ensure the basin is away from natural waterways, a high water table, or drinking water wells.Direct it to an Eva-transpiration bed, which is similar to a constructed wetland (a water-tight planter filled with salt tolerant plants).

Fertilizing corn with urine. Urine is stored and then used to fertilize crops. It is usually diluted between 1:3 and 1:5 parts urine to water. Biomass briquettes. Biomass briquettes are made from agricultural waste and are a replacement for fossil fuels such as oil or coal, and can be used to heat boilers in manufacturing plants, and also have applications in developing countries.Biomass briquettes are a renewable source of energy and avoid adding fossil carbon to the atmosphere.

A number of people have switched from furnace oil to biomass briquettes to save costs on boiler fuels. The use of biomass briquettes is predominant where coal and furnace oil are being replaced by biomass briquettes. Use of biomass briquettes can earn Carbon Credits for reducing emissions in the atmosphere. Biomass briquettes also provide more calorific value/keg and save around 30-40 percent of boiler fuel costs.

A popular biomass briquette takes a waste produce such as sawdust, compresses it and then extrudes it to make a reconstituted log that can replace firewood. It is a similar process to forming a wood pellet but on a larger scale. There are no binders involved in this process. The natural aligning in the wood binds the particles of wood together to form a solid. Burning a wood briquette is far more efficient than burning redwood.

Moisture content of a briquette can be as low as 4%, whereas green firewood may be as high as 65%.
