Currently, plastic waste is a very serious threat because plastic waste pollution can harm all living things around and also harm the environment. The increasing volume of plastic waste is due to the lack of processing technology, so that the volume of plastic waste is increasing day by day. Plastic is a material that is difficult to decompose because it is non-biodegradable. One application of plastic waste processing technology offered in this study is to use the pyrolysis principle. Pyrolysis is a method of converting plastic into fuel oil through a thermal decomposition process without the use of oxygen. The pyrolysis process used with a variety of reactors equipped with glass wool and reactor variations without glass wool. The purpose of this study was to compare the yield of pyrolysis oil with a variety of reactors equipped with glass wool and reactors without glass wool. The plastic used is OPP (oriented polypropylene), with a constant reactor heating temperature of 200° C. The pyrolysis process is carried out for 1 hour each test, and the condenser cooling temperature is 28° C. Based on the results of the research, the reactor variation with glass wool got the highest oil weight of 175 grf, while the reactor variation without glass wool got the lowest oil weight of 17 grf. With a variety of reactors equipped with glass wool, the heat generated is more concentrated into the reactor core, resulting in higher oil weight and a more efficient pyrolysis process.

The increasing use of plastic bottles in the environment caused by the rise of teenagers who like to show off a brand of plastic-based beverage products. This makes environmental conditions worse because plastic waste takes a long time to decompose. From many studies conducted, it turns out that plastic waste can be converted into fuel oil. Waste that is used is indeed derived from plastic materials because plastic waste that is processed by pyrolysis produces liquid material that will form oil. There is a simple way of processing plastic waste into fuel oil by means of pyrolysis. This method is easy for everyone to do because it is an easy tool to make. The purpose of this study is to compare the quality of fuels made from the pyrolysis process with fuels that already exist today.

Limbah plastik Low Density Poly Ethylene (LDPE) tidak dapat terurai oleh mikroorganisme, tidak bernilai jual sehingga tertimbun di Tempat Pembuangan Sampah Akhir. Salah satu metoda pengolahan limbah plastik adalah proses pirolisis. Tujuan penelitian ini menentukan jenis bahan bakar minyak (BBM) produk pirolisis dan menentukan efisiensi tertinggi yaitu nilai tertinggi energi yang dihasilkan terhadap penggunaan bahan bakar untuk proses pirolisis. Peralatan pirolisis yang digunakan adalah 1 unit reaktor dan 1 unit kondensor. Karakteristik BBM yang dianalisa adalah cetane index, density, sulfur content, kinematic viscosity, flash point, dan caloric value dari proses pirolisis yang memvariasikan temperatur pembakaran di reaktor 200°C, 250°C, 300°C dan proses di reaktor dengan dan tanpa penggunaan 1% katalis zeolit alam terhadap 2,5 kg limbah plastik LDPE selama 6 jam. Setelah BBM yang dihasilkan terindentifikasi jenisnya, dilakukan pengkajian efisiensi energi produk BBM terhadap penggunaan bahan bakar pada proses pirolisis. Hasil analisa terhadap karakteristik produk BBM yang dihasilkan di setiap variasi temperatur pirolisis dengan dan tanpa penggunaan katalis merupakan bahan bakar jenis kerosin. Efisiensi tertinggi sebesar 72,51% adalah pada kerosin yang dihasilkan pada pirolisis menggunakan katalis pada temperatur 250°C dengan perbandingan nilai energi 20.402 kkal untuk kerosin hasil pirolisis limbah plastik LDPE dan 28.137 kkal untuk penggunaan bahan bakar Liquefied Petroleum Gas (LPG) pada proses pirolisis. Pirolisis dengan penggunaan katalis zeolit 1% pada suhu 250°C terbukti menjadi cara yang efisien dan berkelanjutan untuk pengolahan limbah LDPE menjadi BBM jenis kerosin.Low-Density Poly Ethylene (LDPE), plastic waste cannot be broken down by microorganisms in the soil, has no sale value, so it is buried in the final waste disposal site. One of the plastic waste treatment methods is the pyrolysis process. The purpose of this study was to determine the type of fuel oil from pyrolysis products and to determine the energy efficiency produced against the highest fuel use. The pyrolysis equipment used is 1 reactor unit and 1 condenser unit. The characteristics of the fuel oil product analyzed are the cetane index, density, sulfur content, kinematic viscosity, flash point, and caloric value of the pyrolysis process which varies the combustion temperature in the reactor by 200°C, 250°C, 300°C and the process in the reactor, with and without the use of natural zeolite catalysts 1% against 2.5 kg of LDPE plastic waste for 6 hours. After the type of fuel produced is identified, an energy efficiency assessment of the fuel product is carried out on the use of fuel in the pyrolysis process. The results analysis show that the all product of fuel oil is a kerosene-type of fuel. The highest efficiency of 72.51% is the kerosene produced in pyrolysis using a catalyst at a temperature of 250°C with an energy value ratio of 20,402 kcal for kerosene from pyrolysis of LDPE plastic waste and 28,137 kcal for the use of Liquefied Petroleum Gas (LPG) fuel in the pyrolysis process. Pyrolysis using a 1% zeolite catalyst at 250°C has proven to be an efficient and sustainable way to treat LDPE waste into kerosene fuel.

The production of pyrolysis oil from polypropylene plastic waste was examined over molybdenum modified alumina-silica catalysts (Mo/Al-Si). The reactions were carried out with 1 L of batch reactor under atmospheric pressure at 430 °C. The pyrolysis oil yield was in the order, 10% Mo/Al-Si > 5% Mo/Al-Si > the absence of catalyst. The 10% Mo/Al-Si was highest activity due to the stronger acidity facilitating the pyrolysis reaction. It accelerated the reaction to produce the pyrolysis oil at lower temperature. Comparison of the pyrolysis oil properties to the standards of the diesel fuel from Thai Department of Energy Business shows that the color and the distillation were within standards. Moreover, the results reveal that the kind of raw material affected the product yield of pyrolysis process.

Treatment And Disposal

Given the scenario of difficulty of equalizing treatment and disposal costs, environmental risks and reduction of mass and volume of waste, the pyrolysis process presents itself as a promising option of heat treatment for the most varied types of waste. The present work aims to enable the transformation of plastic waste into combustion engine fuels. And specifically, perform the pyrolysis process for fuel generation through plastic waste, and describe the benefits generated by the transformation process. The methodology used is the case study, with qualitative approach. To obtain the fuel, it was necessary to use equipment that can degrade the plastic waste by heating it, being possible with the use of a pyrolysis oven. Heating the plastic residue inside the oven without the presence of oxygen causes the residue to melt without burning, releasing vapors, which upon exiting the heating chamber and finding the condensation chamber turns the vapor into liquid, more precisely into fuel oil. However, it was noticed that the transformation of plastic waste into fuel through pyrolysis causes the reduction of the impacts generated by solid waste disposal in the environment, water and air. In addition, it enables a new form of fuel generation, since previously it could only generate fuel from oil.

KKN-PPM activities aims to 1) increase public awareness and participation related to environmental hygiene, 2) increase self-supporting community for productive economy through plastic waste processing. Botutonuo village has a coastal tourist area as the community's flagship. Coastal tourist areas in this village need to be managed properly considering the increasing number of tourist visits with waste disposal potential is also increasing. The method applied in this activity is the increase of community participation in the form of healthy environmental action by processing plastic waste into a material of economic value and facilitated by the students. The results of this activity form the mindset of the community in the management of plastic waste, the availability of plastic waste processing tools into fuel oil and the formation of "KUBE Doyan Sampah" consisting of several village youth who manage the business of processed waste plastic
