Eco-friendly Treatment of Trash and Methane Gas (CH4) to Alleviate Greenhouse Effect

What kind of new energy sources for tomorrow? How to meet the demand of incessant increase of population without compromising the future of earth? Here lies the dreadful challenge.

The world population has risen from 2.3 billion in 1950 to (6.7 - 7) billion today and shall probably  culminate in 8 billion in 2025.

But, actually an African consumes 35 times less energy than a North American, an Indian 20 times less and a Chinese 10 times less as well. If energy consumption can be stabilized and lessened because of better energy saving policies applied in haste in advanced countries, the energy consumption of developing countries is continuously in growth.

The most optimistic statisticians estimate that energy increase in the world as a whole could be well evaluated at 50 percent in the next quarter of century.

Until now 85 percent of global energy consumption was made available by means of combustible fossils such as coal, fuel oil and gas. But slowly this kind of natural energy resources shall come inexorably to an end one day.

Above all, exploitation of these fuels engenders the emission of CO2 (carbon dioxide) and the amplification of its spread in atmosphere has become a great threat for the survival of mankind because of the climatic upheaval due to global warming. Fair enough, every country is diversifying the energy sources and at the same time adjusting themselves according to the local geographical environment.

For long time, nuclear power energy development was envisaged by ameliorating protection against the leak of radioactivity, if there is any. Also, complete control of fusion, Eolian or wind energy, solar energy, geothermal energy and hydroelectric power energy etc. must be undertaken to meet any dearth of energy supply.

In Nepal it is impossible to rely on rivers because of global warming there will be possibly no water streaming down from the glaciers of the Himalayan mountains in a very short span of time.

Meanwhile, a judicious and efficient brand-new way could be envisaged for the treatment of city garbage by simply sleuthing around everywhere the new methods made available by advanced countries, producing methane gas (CH4) through the process of controlled putrefaction which is definitely used with success elsewhere all over the world, thus providing lighting and energy for a whole city.

Some of the major ecological token-gestures for energy saving:

The rule of “4Rs”, namely,
1.Re-use
2.Repair
3.Reduce and
4.Recycle

All your electrical apparatus must be put off before you go to sleep because all of them in sleep mode (for example; hi-fi chain, tape recorder, television, refrigerator, radio-alarm, computer, washing machine, washer-dryer, dishwasher and ceiling fan etc.) consume in a year almost as much as a fridge in activity.

You must use a thermostat to keep the temperature of an apartment around 18°C.

Give importance to the label quality of an electrical equipment. For instance, class A apparatus can  consume almost 3 times less energy than a class C; equally applicable to the consumption of water and the level of soundproofing. Moreover, it is suitable to use more and more led electric bulbs in order to diminish power consumption.

Use a good thermal insulation of your houses to make the energy saving of about 10 to 30 percent.  Prefer train to air flight for your voyage within 1500 kilometers.

In towns and cities, use public transports such as bus, tramway or tube instead of personal cars. That is one of the ways to produce less CO2 (carbon dioxide) to alleviate greenhouse effect.

To consume with prudence so as to produce less household and industrial wastes and they must be  biodegradable. Avoid littering with plastic bags and paper, the sign of unconsciousness of civility of the citizenry.

In near future, hydrogen gas (H2) could constitute the principal vector of energy for multitude of  utilization; mostly for personal vehicles equipped with batteries to produce power.

Already many world renowned car-makers are ameliorating the output and everybody hopes that very soon H2 shall be the major fuel for mankind. And it is relatively easy to obtain it from the natural sources. (4H2O = 4H2 + 2O2), where H2O stands for water, O2 for Oxygen and H2 for Hydrogen.

NB: Denmark, Germany and France have become expert in energy powerhouse implantation out of biogas methane (CH4). In France the name of the society is NASKEO ENVIRONNEMENT whose CEO is Aurélien Lugardon. This above mentioned society can install the whole plant for the cost of 1.5 million euros (1 euro = 130 NR approx.) in the EU; treatment of garbage ranging from 3,000 tons to 50,000 tons per year generating from 100 kW to several MW of electricity, EU standard ISO (9001 & 9002).

If Nepal adapts such biogas powerhouses by means of joint venture, it shall cost relatively less. Those municipalities that want to get rid of their garbage and at the same time produce energy for lighting from methane gas (CH4) could consult the respective Embassy, if need be.
