Ethanol Fuel Production from Waste Banana Peelings

April 28, 2018 General Studies

This study entitled “Ethanol Production from Waste Banana Peelings” aims to produce an alternative way in producing energy. Banana chips, banana con hielo, banana cue and other Filipino delicacies made up of banana are some of our favorite foods. But after the consumption of the flesh, we are just throwing out the peelings as garbage. Our country today is facing two major problems, energy crisis and proper waste disposal. This study used waste banana peelings to produce amount of ethanol. Ethanol or ethyl alcohol, drinking alcohol, grain alcohol is popularly used as an alternative for engines.

Ethanol is mainly produced by fermenting grain or farm waste and will be distilled afterwards. This study can be a great help to solve the stated problems. The researchers used waste banana peelings as source of ethanol. The banana peelings were collected after the consumption of its flesh. The peelings were then finely chopped and macerated. The peelings were left to ferment for about 5-7 days. There were two treatments used in this study. T1 is made up of extracted juice from the macerated peelings and T2 is made up of juice with pulps.

After seven days, the percent yield was determined for both treatments. The distillate was lit to show that there really is alcohol in the product. As the results show, T2 has the greater yield than T1. Banana waste peelings can be an alternative source of ethanol which can be utilized as alternative source of fuel. METHODOLOGY 1. Add fruit to a barrel. •Obtain throwaway fruit from your local grocer or another source. Fruit that is rotten may be used in lieu of edible food. •Add fruit until the barrel is approximately 1/3 full.

It is important to not exceed this amount, as the barrel may overflow during fermentation. 2. Mash the fruit with a pole or other blunt object. 3. Add water and yeast to the barrel. •Although standard yeast can be used, it is best to use ethanol tolerant yeast from a wine-making supply store. •Add 1 to 2 packets to the barrel. 4. Cover the barrel. 5. Monitor the sugar content of the barrel. •Check the sugar content daily with a hydrometer. •Over the course of approximately 10 days, the sugar content should reduce gradually until none is left. 6.

Distill the mixture by using a reflux still, this can be purchased on the Internet. •Do this immediately after the sugar is gone from the mixture. Not doing so could allow materials to develop that could ruin your engine. •Put the mixture into a reflux still. •Follow the manufacturer’s instructions to complete the distillation process. 7. Filter the mixture. •The ethanol that you are left with after the distillation process will still have a minor impurity of water inside of it. To remove this water, you need to use a specialized fuel filter that can filter the water out.

These filters are made out of specially-designed fabrics that allow ethanol molecules to pass through while trapping the water. 8. Add gasoline (petrol) to the ethanol (optional). •Depending on your engine type and regulations that apply to ethanol production in your area, add the required amount of gasoline (petrol) to the mixture. A fuel that is commonly produced is E85, which is 85 percent ethanol and 15 percent gasoline (petrol). The Feasibility of Waste Banana Peelings as a Good Source of Ethanol Arianne Gayle Limin Maroussia Verbo Kim Punzalan Hanz Christian Jimenez

Richard Malit An Investigatory Project Submitted to Mr. Junel Ocampo for our Performance Task Saint John Academy Grade 8 – St. Peter REVIEW OF RELATED LITERATURE The word alcohol derives from Arabic al-kuhul, which denotes a fine powder of antimony produced by distilling antimony and used as an eye makeup. Alcohol originally referred to any fine powder, but medieval alchemists later applied the term to the refined products of distillation, and this led to the current usage. Ethanol is a clear liquid alcohol that is made by the fermentation of different biological materials.

This alcohol is known to have many uses, but one in particular is becoming more popular. Ethanol, the most widely used biofuel, is made in a process similar to brewing beer. The ethanol in the end is blended with gasoline to improve vehicle performance and reduce air pollution. Ethanol is made of liquid alcohol that is manufactured by the fermentation of a wide variety of biological materials. These materials include grains such as wheat, barley, corn, wood, and sugar cane. Ethanol is best produced from lower value grains such as barley, corn and feed wheat.

Higher value “bread” wheats would remain in ample supply for export sales, when Canada begins major ethanol manufacturing. Also, poor quality (weather damaged, immature) grains which are less suitable for either human or livestock use are excellent for ethanol production. Ethanol is used as miscible (mixable) in all proportions with water and with most organic solvents. It is useful as a solvent for many substances and in making perfumes, paints, lacquer, and explosives. Alcoholic solutions of nonvolatile substances are called tinctures; if the solute is volatile, the solution is called a spirit.

Commercial Alcohols have grown to be the largest manufacturer and supplier of industrial grade alcohol (ethyl alcohol or ethanol). Although ethanol has been traditionally thought of as a beverage product for use in spirits, beer and wine, ethanol is an important, viable alternative to unleaded gasoline fuel. Ethanol is used as an automotive fuel; it can be used alone in specially designed engines, or blended with gasoline and used without any engine modifications. Motorboats, motorcycles, lawnmowers, chain saws etc. can all utilize the cleaner gasoline/ethanol fuel.

Most importantly, the millions of automobiles on the road today can use this improved fuel. Fuel ethanol what has been called “gasohol” – the most common blends contain 10% ethanol mixed with 90% gasoline (E10). Because the ethanol is a high-octane fuel (2. 5 – 3 points above the octane of the blending gasoline) with high oxygen content (35% oxygen by weight), it allows the engine to more completely combust the fuel, resulting in fewer emissions. Since ethanol is produced from plants that harness the power of the sun, ethanol is also considered a renewable fuel. Therefore, ethanol has many advantages as an automotive fuel.

Ethanol is a water-free alcohol and there for can withstand cooler temperatures. Its low freezing point has made it useful as the fluid in thermometers for temperatures below -40°C, the freezing point of mercury, and for other low-temperature purposes, such as for antifreeze in automobile radiators. When using ethanol as engines it began in 1979 most automobile manufacturers did not even address alcohol fuels. As soon as each manufacturer tested their vehicles, they approved the use of a 10% ethanol blend. Today, all manufacturers approve the use of ethanol and some even recommend ethanol use for environmental reasons.
