Food waste? Food FUEL!

What is Bio-Fuel? 

Bio-fuels are liquid fuels that are derived from materials such as wastes of plants or animals.

Why is Bio-Fuel Essential?

Due to the drastic increase of population, food consumption increased, gradually forming bounty of food wastes.

Food waste is being produced excessively and is increasing rapidly due to the immense population growth. Despite all the efforts to reduce the rate of production, it is visually proven that this acceleration is inexorable. As researchers realized this fact, they studied ways to focus on the potential possible solutions that can be advantageous than to dissipate inessential effort.

This alteration of perspective engendered a huge technological advancement. Researchers formulated a method to convert organic waste into useful energy source. Briefly explaining the procedure, the discarded organic waste are reduced in size and fermented. In this process, the solid precipitation are grinded into nutritious fertilizer, and the gas produced are utilized to turn the gas motor, affecting the generator to produce electricity.

Categorizing the benefits of food wastes to Bio- Fuels

  1. Can reduce carbon emission: Environmental Benefit.

Fossil fuel, one of the commonly used fuels is the cause of massive production of carbon dioxide, engendering green house effect, increasing the temperature more than  0.6 Celsius since the year 2000.(When 1 C increases, half of the population of forests of alpine region disappears,  and the largest coral reef region, Great Barrier Reef will never regain its original shape caused by bleaching. )

Bio-Fuels can reduce carbon emission by 85% compared to mineral diesel including fossil fuels

With the help of bio-fuels, huge amount of Co2 can be reduced, preventing the potential environmental difficulties.

2. Can increase energy production: Economic Benefit

The world lacks energy. According to US Energy Information Administration(EIA), total energy consumption per year came up to 493 quadrillion (493,000,000,000,000,000).

The world craves for energy. Oil, coal, gas, nuclear energy are the most used energy source in human history: but the global denizen begs for more. Realizing the urgency of the matter, researchers are trying to find an alternative energy source that can be efficient and environmentally harmless. The alternative energy sources brought up till now, has number of flaws that cannot be ignored.

Bio-fuels, on the other hand, are made up of “pure” rubbish. The only requirements are the facilities and professionals of the area.

The whole concept of food wastes being reproduced as crucial energy resource is revolutionary: trash to energy.

 

 

3. Can lower space requirements for landfills: Social Benefit

The most popular way to discard food wastes are to pludge them in landfills. This causes environmental, spatial, and social problems. Perilous leachate, land consumption in hectares, and NIMBY(Not In My Back Yard) phenomenon often lacerates relationship between neighbors. Landfills emits unbearable odors and contaminates the land surrounding that area, giving huge disadvantages to the residents inhabiting the region.

However, in the process of creating bio-fuels, the stenches are collected and purified, leaving no scent of reek behind. Also, the wastes are collected in a artificially created room to prevent the leachate from leaking.

 The benefits of recycling food waste are clear, increased energy production, lower carbon emissions, lower space requirements for landfills, and lot more.

People should not view food wastes as squalid rubbish,

But as Necessary Source of Energy.

The Eighth Continent: Zealandia

 

Under the waves of Pacific Ocean lies a giant land that once was called a continent: Zealandia, geologists say.

Zealandia is 5 million square kilometers big, including  New Zealand and New Caledonia. A team of scientists from New Zealand, Australia, and New Caledonia argue in the March/April issue of GSA Today that this single crust is significantly separated from Australia.

“If you could pull the plug on the world’s oceans, then Zealandia would probably long ago have been recognized as a continent,” says team leader Nick Mortimer, a geologist at GNS Science in Dunedin, New Zealand.

“The results are pushing us to rethink how broadly we can or should apply the established definition of geological continental landmasses,” says Patricia Durance, a mineral geologist at the GNS Science office in Lower Hutt, New Zealand.

The researchers concluded Zealandia ought to be one of the continents. Zealandia didn’t break away from another continent, as it was thought to be in the past. The India-sized continent should be treated as the seventh continent of the world.

“If the elevation of Earth’s solid surface had first been mapped in the same way as those of Mars and Venus – which lack the arbitrary datum of opaque liquid oceans – we contend that Zealandia would, much earlier, have been investigated and identified as one of Earth’s continents,” the researchers noted.

“This is not a sudden discovery but a gradual realization; as recently as 10 years ago we would not have had the accumulated data or confidence in interpretation to write this paper.”

The scientists said classifying the area as one continent wasn’t just a matter of putting “an extra name on a list”.

“That continent can be so submerged yet unfragmented makes it a useful and thought-provoking geodynamic end member in exploring the cohesion and break-up of continental crust.”
