Bioplastic from banana peels

  1. 1. BIOPLASTIC FROM BANANA PEELS GUIDED BY Dr.ABDUL RASHEED H.O.D CHEMICAL ENGG: DEPT T.K.M.C.E PRESENTED BY AKHIL DAS BONIFACE B JITHIN G SIDDIQ S SRINATH A R 1
  2. 2. OBJECTIVES • Production of bioplastics from banana peels as a substitute for the conventional plastics • To minimize pollution in the environment by the use of bioplastics 2
  3. 3. Literature review  The banana fruit’s peel is selected for the experiment as it is a waste material rich of starch. 3
  4. 4. MATERIALS REQUIRED Glass pipette Beakers Bunsen Burner Glass stirring rod Oven Petri dish Gauze pad 4
  5. 5. EXPERIMENT PLANNING I. Preparation of banana skins: 1. The peels of the bananas were removed using a stainless steel knife. 2. An 800ml beaker was filled with distilled water and placed over a Bunsen Burner. 3. The banana peels were dipped in 0.5% solution and placed in the beaker and were boiled for 30 minutes. 4. After the boiling process, the beaker was removed from the Bunsen burner and the peels were decanted off the water and placed on and covered with a dry gauze pad, left to dry for 30 minutes. 5. After the peels were dried, they were placed in a clean 800ml beaker. 6. Using a hand blender, the peels were pureed until a fluid paste was formed. 5
  6. 6. II. Production of the plastic: 1. 25ml of banana paste was placed in each 50ml beaker. 2. 3ml of HCl was added and the mixture was mixed using a glass stirring rod. 3. 2ml of propan-1, 2, 3-triol was added to each beaker. The mixture was stirred again. 4. 3ml NaOH was added and the mixture was stirred once more. 5. The mixture was poured into a petri dish and put in the oven at 130°C. It was baked for half an hour. 6
  7. 7. EXPECTED RESULTS When banana peels were dipped in 0.5% solution prior to the boiling and blending process, the boiling water was removed and 25ml of the banana peel paste was used (0.5M or 0.1M HCl and NaOH) bioplastic can be produced and feasible strength test can be done. 7
  8. 8. FUTURE ASPECTS • SONY CO. has replaced its employees’ ID cards using bioplastics so it is evident that it can be developed into large scale practices • Many other companies are also endeavoring this venture 8
