A study of hidden potential for Solid waste production from vegetative and fruits.

The principles behind the slogan "reduce, reuse and recycle (3R)" have not been widely implemented yet in Bangladesh. To keep it in mind citrus vegetative and fruits which are mostly abundant in Bangladesh. These citrus vegetative and fruits are used for electricity generation. During and after electricity generation it is produced some bi-products like hydrogen gas, methane gas and bio fertilizer. The bio-fertilizer is produced as a solid waste. The citrus vegetative and fruits were Bryophillum pinnatum leaf, Arum leaf, Myrobalan, Aloe vera, Tomato and Water Hyacinth. Research finally focused on using vegetative and fruits waste for the production of bio-electricity. Subsequently, further uses of vegetative and fruits waste have been explored. This includes accessing dietary nutrients and antioxidants from selected citrus vegetative and fruit types. This is just the tip of the iceberg because international studies have shown that there is huge potential trapped in vegetative and fruits waste. During the processing of vegetative and fruits, thousands of tonnes of solid and liquid waste are produced. Solid waste is generated in the form of skins, pips and stalks, residue of the vegetative and fruits and liquid waste from water used to wash vegetative and fruits or clean equipment. A comparative study of solid waste production has been done from 6 types of vegetative and fruits during and after electricity production. Most of the results have been tabulated and graphically discussed. It has been designed and fabricated a mini PKL power plant for for practical use at the off-grid areas of Bangladesh. This mini power plant presents the salient design features of the PKL electric system, which is the first of its kinds in the world. Experiences regarding the operation and maintenance of this PKL power plant, which has been functional in Bangladesh. Attempts have been made to correlate certain measurable parameters anticipated performance of the mini PKL power plant. As a practical application this mini power plant deals with the technology of PKL electricity used in application at the rural areas in Bangladesh. The appliances may not compete with the conventional electricity but in near future it is expected that the costs of the PKL electrode concentration cells will drop drastically, performances of several electrical appliances run on PKL electricity. 1KW or, 1000 watt mini power plant has been set-up at Islamabad village, Union-Rajapur, Thana-Kanighat in Sylhet District of Bangladesh. Energy saving AC bulbs are using for 57 houses, 10 energy saving energy bulbs and a 80 watt AC fan are using in a mosque of that village. This paper expressed the required PKL jouice, positive and negative electrodes, charge controller, modified square wave inverter, the panel board and storage batteries. Storage batteries are used for constant output voltage. The panel board is made by a DC voltmeter, AC voltmeter & DC voltammeter as indicators of the produced electricity. This mini power plant has been set-up for experimental purposes to develop "an operational system of clean energy production and supply using Pathor Kuchi Leaf (Bryophilum Pinnatum)" electricity to the complex rural area where the grid electricity is absent. Most of the results have been tabulated & graphically discussed. Furthermore, the electrical and chemical properties of PKL electricity generation device have been studied in this research work by the researchers. It has been studied the following characterizations: The electrical properties are: internal resistance, voltage regulation, energy efficiency, pulse performance, self discharge characteristics, discharge characteristics with load, capacity of the PKL cell, temperature characteristics and life cycle of the PKL cell. The change of PKL power efficiency with time. The internal resistance is nearly 0.60 ohm, voltage regulation is close to 9%, pulse performance is so good and energy efficiency is about 65%. Internal resistance is nearly 0.25 ohm, which is nearly good. Voltage and current reduces exponentially and the concentration of copper decreases gradually with time for PKL cell which also reflect the higher life time of the cell. Voltage and current linearly decreases with decreasing the concentration of copper ions. Some Practical Applications for static and dynamic method have been studied. Most of the results have been tabulated and graphically discussed. [ABSTRACT FROM AUTHOR]
