# Performance Study of Reactor Pyrolysis of Plastic-Rice Pyrolysis Against some polymer waste

Introduction

The increasing use of plastic materials in various sectors of life has led to a significant rise in plastic waste production. This growing plastic waste poses a substantial threat to the environment, and it is essential to find innovative solutions to mitigate this issue. One promising method is pyrolysis, which can convert plastic waste into energy. This study aims to analyze the performance of reactors in pyrolysis that process plastic waste and rice husk, with the goal of increasing oil yield and understanding the characteristics of processed products.

Background

Plastic waste is a significant environmental concern, and its disposal poses a substantial threat to the ecosystem. The production of plastic waste is expected to continue to rise, and it is essential to find alternative methods for managing this waste. Pyrolysis is a promising method for converting plastic waste into energy, and it has gained significant attention in recent years. This process involves the thermal decomposition of plastic waste in the absence of oxygen, resulting in the production of oil, gas, and solid residues.

Methodology

The method used in this study is a complete random design (RAL) with two factors. Three types of plastic waste were tested in this study, including plastic cups of mineral water (P1), mulch plastic (P2), and burlap sack plastic (P3). Each type of plastic was mixed with rice husk in three mass variations, namely 8 kg (m1), 9 kg (m2), and 10 kg (m3). The parameters observed in this study include yields, reactor temperatures, and oil characteristics produced.

Experimental Design

The experimental design used in this study is a complete random design (RAL) with two factors. The two factors are the type of plastic waste and the mass of rice husk used. The three types of plastic waste tested in this study are plastic cups of mineral water (P1), mulch plastic (P2), and burlap sack plastic (P3). Each type of plastic is mixed with rice husk in three mass variations, namely 8 kg (m1), 9 kg (m2), and 10 kg (m3). The experimental design is shown in the following table:

Type of Plastic	Mass of Rice Husk (kg)
P1	m1 (8 kg)
P1	m2 (9 kg)
P1	m3 (10 kg)
P2	m1 (8 kg)
P2	m2 (9 kg)
P2	m3 (10 kg)
P3	m1 (8 kg)
P3	m2 (9 kg)
P3	m3 (10 kg)

Results

The results of this study showed that the highest yield was achieved by oil from burlap sack plastic (P3M1) of 13.01%, while the lowest yield was obtained from mulch plastic (P2M1) which only reached 0.65%. The pyrolysis process shows that the oil begins to drip when the reactor temperature is between 81.6 ° C to 95.2 ° C. The highest temperature recorded during the study was 162 ° C, which was achieved in 222 minutes (3.7 hours) when using a mass husk mass of 8 kg.

Physical Characteristics of Oil

The physical characteristics of the oil produced in this study were also analyzed. The results showed that the highest density of oil is found in mineral water plastic (P1M3) which is 0.80 gr/ml, while the lowest density is in oil from burlap plastic (P3M3) which is 0.73 gr/ml. Both of these values are still in the range of density of kerosene fuel which usually ranges from 0.78-0.81 gr/ml. For thickness, oil from mineral water plastic has the highest value of 1.09 cp, while oil from goning sack plastic has the lowest value of 0.63 CP, which is close to the viscosity of gasoline fuel which is around 0.652 CP.

Conclusion

From the results of this study, it can be concluded that the use of pyrolysis that processes plastic waste and rice husk provides good potential for energy conversion. The yield and physical characteristics of the oil produced varies depending on the type of plastic waste and mass of rice husk used. This research opens opportunities for further development in processing plastic waste into alternative energy that is more environmentally friendly and sustainable.

Recommendations

Based on the results of this study, the following recommendations are made:

Further research is needed to optimize the pyrolysis process and to improve the yield and physical characteristics of the oil produced.
The use of pyrolysis for processing plastic waste and rice husk should be further developed and implemented on a larger scale.

The experimental design used in this study is a complete random design (RAL) with two factors, which may not be sufficient to capture the complex interactions between the type of plastic waste and the mass of rice husk used.
The study only analyzed the physical characteristics of the oil produced, and further research is needed to determine its chemical composition and other properties.
The study only used three types of plastic waste, and further research is needed to determine the suitability of pyrolysis for processing other types of plastic waste.
