It is a substance that is added externally to shoes to make them look cleaner and help them shine better. Shoe polishing agent is an important 'food' for the shoe. Today, shoe polish is usually made from a mix of natural and synthetic materials, including naphtha, turpentine, dyes, and gum arabic, using straightforward chemical engineering processes. Various natural substances have been used as shoe polish for hundreds of years, such as banana peel, beeswax, tallow, mango shell, charcoal etc. For this study, banana peel is taken as a raw material as it contains huge amounts of potassium and calcium which are able to act on leather surface as cleaning agent as well as shining. Banana is the common name for a fruit and also the herbaceous plants of the genus Musa which produce the commonly eaten fruit. They are cultivated primarily for their fruit, and to a lesser extent for the production of fiber and as ornamental plants. Banana (Musa sapientum), is grown worldwide and consumed as ripe fruit or used for culinary purposes. Peels form about 18-33% of the whole fruit and are a waste product. Global production of bananas is estimated to be around 48.9 MT. It has originated from South– East Asia with M. acuminata and M. balbisiana as its ancestral species. It is an herbaceous plant of the family Musaceae. In Bangladesh, major districts of cultivated Banana are Narsingdi, Gazipur, Tangail, Rangpur, Bogra, Natore, Pabna, Noakhali, Faridpur, Khulna in our country. Bangladesh ranks 14th among the top 20 banana producing countries in the world. The country produces nearly 1.00 million tons of bananas annually. The total per capita consumption in Bangladesh is about 4.7 kg. In addition, banana stood first position among the fruits producing in the country and supplies 42% of the total fruit requirements in the country and also its financial return as a crop is higher compared to other fruits and field crops. Significant quantities of banana or plantain peels, equivalent to 40% of the total weight of fresh banana, are generated as a waste product in industries producing banana-based products. Musa sapientum peels were analyzed for minerals, nutritional and anti – nutritional contents.

The oils and the potassium of the banana polish preserve shoes. The natural oils in the banana soak into the leather, helping shoes to last longer, whilst potassium, a key ingredient in commercial shoe polish, is found in abundance in bananas. The most significant approach in preventing environmental pollution is the idea that prevention is better than reuse, reuse is better than recycling, and recycling is better than disposing of the wastes. Here keeping this motto, banana peelings are used for the production of shoe polish. As a result, extraction of banana peel may be used as an ingredient of shoe polishing. It is very economic as well as toxic chemical free which saves our environment and reduce wastage. 2. Materials and Methods 2.1. Materials Banana peeling is the raw material to work as a shining agent for shoe polish. The banana peelings were collected from public markets and another locality and processed.

So, Banana peel extract sample 2 is best for the producing of banana peel extract as the concentration of potassium is high. 2.6. Preparation of Shoe Polish Sample from the Banana Peel Extract (Sample 2) For the production of the polishing agent from the banana peel, the process of the banana peel extract sample 2 has been repeated. First a beaker (1000 ml) and a measuring cylinder (250 ml) were cleaned by water and dried them in an oven at 100°C. 150 gm banana peelings powder was taken and put it to the beaker. 500 ml hot water was added into the beaker and powder was dissolved with the help of glass rod. Then gravity filtration was done by the filter paper.380 ml liquor was found after filtration. Heat was given to the beaker by the bunsen burner. When the liquor was half of its amount, then besin was used to dry it more by using water bath. Then oven was used to dry it more at 40°C. After some time almost, dry dye of polishing agent was found. The total weight of the dry dye is 52 gm. So, the result is 35.18% for the 100 gm banana peels powder. 2.7.

Procedures First a beaker (500 ml) and a measuring cylinder (250 ml) were cleaned by water and dried them in an oven at 100 °C. Banana peel extract, Beeswax, Soap flakes, Gum arabic powder, Icing sugar and Carnauba wax was taken by weighing and was done by electric balance and put it for next use. Distilled water was poured into the beaker (measuring was done by the measuring cylinder). The beaker was placed on the tristand and water was boiled by applying heat of bunsen burner. The beeswax was sliced and when water was in boiling form, beeswax was added into it and the mixture had to stir with glass rod. After melting the Beeswax, Carnauba wax, Soap flakes and Banana peel extract was added into the mixture. The mixture was boiled until it turned into a smooth paste. Then the heat was turned off and icing sugar, gum arabic powder and lemon grass oil were mixed into the mixture. Then the sample was rotated with the help of electric rotator for some minutes. The polish sample was ready after cooling.

RESULTS AND DISCUSSION 3.1. Melting Point Sample-1 contains higher melting point and Sample-3 contains lower melting point. Very higher and lower melting point is not suitable for shoe polish except some special cases. Higher melting point contain shoe polish is very hard type and lower melting point contain shoe polish is liquid type. Here among three samples, sample-3 is best for our country. 3.2. PH Here sample-1 contains lower pH and sample-3 contains higher pH. Sample-1 pH is stands on the medium acidic range but high acidic range is not considered as a better shoe polish. Sample-2 pH is stands on the medium acidic range or slightly near neutral and this range is considered as a better shoe polish. pH of sample-3 is stands on the neutral range and this range is considered as a better shoe polish. 3.3. Moisture Content If moisture content is so high, then polish should turn into liquid form and if so low then should turn into solid form. Solid form is very difficult to use as a shoe polish. Liquid form is better when the polish is water based but when not then it is bad. From the above data sample-1 contains lower moisture content and sample-3 contains higher moisture content. Sample-3 is relatively best for shoe polish. 4. CONCLUSION Shoe polish is an important finishing part of shoe giving the nice appealing and glossy look. And besides that, shoe polish also helps to improve the water repellency property of the leather. So, for getting of these properties, banana peel is the best option. Because, it contains a very significant part of potassium and calcium which works as cleaning and shining agent. Since banana is one of the fruits that we usually have in JETIR1805406 Journal of Emerging Technologies and Innovative Research (JETIR) www.jetir.org 1357 © 2018 JETIR May 2018, Volume 5, Issue 5 www.jetir.org (ISSN-2349-5162) our house and we almost eat every day. By this research, the trash we throw everyday become lesser and make something much useful from it than its usual use. It also promotes good health because whenever we buy shoe polish in the market we are not able to buy or even see a shoe polish that doesn’t have any harmful chemical mixed with it; in this experiment no harmful chemicals are involved because a natural material is used. If all the districts of our country can be brought under banana cultivation, there is a large scope to producing a better-quality shoe polish and we can also export them to earn foreign exchange. And besides that, we can also keep our environment cleaner, greener and safer.
