Production Of RDF-5 Fuel From Waste Within Rajamangala University of Technology Tawan-ok Chanthaburi Campus

Abstract

This research aims to implement solid waste management practices for the production of RDF-5 fuel at Rajamangala University of Technology Tawan-ok Chantaburi Campus. to be used in conjunction with coal in the industry. and analysis of manufacturing costs. Waste used in production including paper, plastic, twigs and leaves waste as the raw material for RDF-5 fuel production, with tapioca starch 2 percent by weight as binder. The research identifies four production steps, including gathering materials, reducing waste size, mixing waste materials with tapioca starch, and compressing with hydraulic press. The research tested the RDF-5 fuel with ASTM standards, including ASTM D 240, ASTM D 3173, ASTM D 3174, ASTM E 75, and timer in the burning of RDF-5 fuel. in finding the right mix Will study from 4 ingredients, namely 50:50:50 (grams), 75:50:50 (grams), 50:75:50 (grams) and 50:50:75 (grams). The study conducted four experiments to determine the optimal mixture, which resulted in 50:50:75 (grams) paper, plastic, twigs and leaves. The research found that the heat value of RDF-5 fuel is 5,842.09 Cal/g, moisture content is 6.62 percent, ash content is 8 percent, and density is 968.18 Kg/m³. The burning time is 27.57minutes. (The calorific value is not lower than the standard of 5,000 calories per grams, The moisture value does not exceed the standard 10 percent, The ash content does not exceed the standard 20 percent and The density is not lower than the standard 600 kg/m³ respectively). 1) The waste reduction results showed that there was a large amount of waste generated in Rajamangala University of Technology Tawan Tawan-ok. Chanthaburi Campus, 261.43 kg per day Production of RDF-5 fuel in the best blend It weighs 175 grams Divided into 50 grams of paper, 50 grams of plastic, and 50 grams of twigs and leaves When used to produce RDF-5 fuel in the amount of 1 kg per day will be able to reduce the amount of waste in Rajamangala University of Technology Tawan Tawan-ok Chanthaburi Campus 0.38 percent per day. 2) The research also found that RDF-5 fuel can be used with coal to increase heat and efficiency while reducing coal consumption. 3) The cost of production of RDF-5 fuel was found to be 7.85 baht per kilogram.
