Philippines: Gas stove is made of environmentally friendly rice husk

Millions of farmers in Indonesia can benefit from a type of gas stove simply by cooking food from gas-turning technology from rice husks. Rice husks are very abundant waste in this island nation, where an average of 58 million tons of rice is produced annually.

This type of stove is very simple in fact it is a metal stove, emitting a transparent blue flame that was invented and put into use in the Philippines and then introduced in Indonesia by Alexis Belonio, a Filipino agricultural engineer. After receiving the Swiss Rolex SS award at a rather special awards ceremony in Manila, Mr Belonio said: ' By using this kind of gas stove equipment rice farmers can save one equivalent to US $ 150 per year, this is much cheaper than using refined petroleum or natural gas. At the same time, using a gas stove with rice husk can help hundreds of millions of farmers in the world to live well with an income of less than 2 USD / day '.

The benefits from Mr. Belonio's invention are that rice husk fuel sources are plentiful and almost ' free, free ', present in farmer households or in rice mills, jobs. Using gas cookers with rice husks can reduce toxic gas emissions and reduce the need for firewood. The Jakarta Post said: ' Every year, Indonesia produces more than 10 million tons of rice husks and most of them become garbage. But now this is a huge fuel source . '

It is known that Mr. Alexis Belonio is one of the 10 faces of the Rolex SS for Business Awards in 2008, in honor of the elite inventors in many different areas, the award was formed since 1976. 5 Those who receive the first-rate Rolex award, each will be awarded an amount of up to 100,000 USD; 5 people received the Rolex Friendship Prize, each will be awarded $ 50,000, including Alexis Belonio. The winners were carefully screened from 1,500 inventors from more than 125 countries around the world. The judging panel is composed of scientists, economists and experts in many fields from all over the world.

The Rolex SS award is global and is one of the most prestigious awards for the world's best inventors in areas that bring progress to people.

Alexis Belonio, 48, is an assistant agricultural engineer assistant, currently teaching at the Philippine College of Agriculture University located in Iloilo City. Mr. Belonio himself was aware that the farmers had used rice husk in cooking food before, but this method of cooking was not very good because it contained soot soot so it was not safe for health. , the heat is not concentrated as much as possible so the cooking time is very slow. ' But with the gasification process I invented, I focused on making a kind of gas stove that can cook food or boil water very quickly. One ton of rice husk can be converted into 415 liters of gas or 378 liters of kerosene , 'added Belonio.

Mr. Belonio's manufacturing process was conducted experimentally at the Minang Jordanindo factory, indicating that only a handful of rice husks were able to boil water for 7 minutes . On the other hand, cooking with a gas stove with rice husk will minimize toxic dust in the household. On the other hand, after burning the rice husk into powdered coal, this charcoal powder can be re-processed to add nutrients to the soil or force it to form cardboard. Earlier, the rice husk gas stove was made by Mr. Belonio in the Philippines since 2003 but its price was quite expensive at that time, up to 100 USD / set, that price could not reach the reach of the majority of people work in agriculture.

Mr. Belonio said: ' By further tests, with funding from Minang Jordanindo, I have been able to create a new gas stove model, cutting down the cost of the original gas stove model. only 25 USD / set. But my ambition is to make the price of gas stove drop to extremely low, only 10 USD / set '.
