The Impact

At present, plastic is a material that is needed by the community at large, where the impact is also very extraordinary after the plastic is used in everyday life which can cause serious problems if the management is not done properly. The problem of plastic waste does not only occur in the city of Semarang, but also in other cities, so that the Ministry of Environment and Forestry has implemented a paid plastic bag program in the short term. But this is only to deal with problems in the short term. In the long run, it will not solve the problem of "plastic waste", because the policy actually encourages people to buy plastic which, of course, will add a new burden for the community to buy it. Based on the above problems, it is necessary to utilize this plastic waste to be made into road pavement materials such as in the manufacture of Asphal Concrette Wearing Course, by making 5 mixed variations ranging from (2 to 10)% of the weight of the aggregate . This research was initiated through a survey process, material procurement, testing of stacking materials, making test specimens, testing specimens. The results of the research can show that the type of Thermosetting plastic waste has a significant influence on the Asphalt Concrete mixture AC-WC heat mixture, including: Density, Marshall Stability, Flow, VIM, VMA, MQ and the remaining Marshall Stability tend to show an increase, moderate VFA and VIMrefusal Density values tend to show a decrease. Thus the plastic waste from the Thermosetting type can be used as a partial replacement of the aggregate for the Asphalt Concrete mixture AC-WC heat mixture with a plastic waste content is limited to a maximum of 10% and at an optimum asphalt content of 5.55%. Thus this research is expected to be of benefit to the industry and the people of Semarang in relation to the use of plastic waste for road pavement.

The increasing global waste plastic pollution is urging people to take immediate actions on effective plastic recycling and processing. In this work, we report the results of processing reclaimed plastic wastes from unsanitary landfill site in Kuwait by using a bench scale continuous auger pyrolysis system. The plastic feedstock was characterised. After a simple thermal densification process, the material was fed to the pyrolysis system at 500 °C. The pyro-oil and wax products were collected and characterised. The process mass balance was developed on dry basis, and the yields of pyro-oil, light wax, heavy wax and gases were 5.5, 23.8, 69.4 and 1.3 wt%, respectively. The findings have indicated that the reclamation of plastic waste from landfill was feasible in terms of the product distribution and characteristics. Further liquid analysis confirmed that the liquid products contained fractions that are comparable to petrol and diesel fuels. The wax products are viable and have potential application as coating, covering and lubrication.

Because of the continuous increase in the amount of plastic waste, catalytic cracking is an interesting method that could be used to convert heavy oil from thermal cracking of plastic waste into fuel. The objective of this study was to investigate the hydrodynamic behavior and the performance of catalytic cracking of heavy oil in a circulating fluidized bed reactor using computational fluid dynamics. The two– fluid model incorporated with the kinetic theory of granular flow was applied to predict the hydrodynamic behavior with a reactive flow. Three reactor geometries were studied, which included a conventional riser, tapered–out riser, and tapered–in riser. The four–lump kinetic model was used to describe the catalytic cracking of heavy oil from waste plastic. A core–annulus flow pattern was found in the three reactor geometries. The solid fraction distribution of the tapered reactor was found to be more uniform than that of the conventional riser. The tapered–in riser showed the highest heavy oil conversion with the lowest gasoline selectivity. However, the heavy oil conversion and gasoline selectivity of the conventional and tapered–out reactors were not significantly different.

Gasification is one of the most important solutions for plastic waste management. We researched the conversion of plastic waste to fuel using sustainable material (Nano Clay) modified with Nano transition metals (TiO2, MnO, and ZnO). This was processed in a fix bed reactor design. After studying the reaction mechanism of the gasification process, we evaluated the optimize (reactor temperature, reaction time and feeding ratio of the modified catalyst) on the gasification process with its application for the modified catalyst on the degradation of polyethylene high density(PEHD), other waste plastic to fuel (CH4, H2, and other light component gasses). This method can be used as an important resource for renewable energy (like generating electricity and clean fuel), rather than waste for landfills and the incineration process which is the main source of CO2 emissions.

ENGLISHThe use of plastic bag tends to increase and it causes the increase of plastic waste. Plastic waste is a hazardous material because it is difficult to be decomposed biologically. Waste management in Indonesia is regulated by Law Number 18/2008 and Government Regulation Number 81/ 2012. Besides the use of biodegradable plastics, reducing the number of plastic bag can be done by implementing a no free plastic bag policy. The policy was issued by the Directorate General Waste Management, Waste and Hazardous and Toxic under the Ministry of Environment and Forestry (KLHK). The content of this policy is to urge people to bring their own bag when shopping, otherwise they have to buy plastic bags. The policy has been implemented in several countries and succeeded in reducing the number of plastic bags significantly. In Indonesia, the pilot implementation of the policy was conducted from February 21, 2016 to June 5, 2016 in 22 cities. Funds raised from the sale of plastic bag are public funds that will be used for waste management activities. By implementating this policy is expected to reduce the use of plastic bag in Indonesia, as in other countries that already have implemented it. INDONESIAPenggunaan kantong plastik yang cenderung mengalami peningkatan, akan meningkatkan jumlah sampah plastik. Sampah plastik merupakan sampah berbahaya karena sifatnya yang sulit terurai secara biologis. Pengelolaan sampah di Indonesia sudah diatur dalam UU No 18 Tahun 2008 dan PP No 81 Tahun 2012. Selain dengan penggunaan plastik biodegradable, penurunan jumlah penggunaan kantong plastik dapat dilakukan dengan menerapkan kebijakan kantong plastik berbayar. Kebijakan ini dikeluarkan oleh Kementerian Lingkungan Hidup dan Kehutanan (KLHK) melalui surat edaran Direktorat Jenderal Pengelolaan Sampah, Limbah dan Bahan Berbahaya dan Beracun. Isi dari kebijakan ini menghimbau masyarakat untuk membawa alternatif kantong plastik saat berbelanja atau jika masyarakat tidak membawa kantong plastik belanjaan, pelaku ritel akan mengenakan harga pada kantong plastik yang diminta masyarakat saat belanja. Kebijakan ini sudah banyak diterapkan di beberapa negara dan berhasil menurunkan jumlah penggunaan kantong plastik secara signifikan. Di Indonesia, uji coba penerapan kebijakan ini dilakukan mulai 21 Februari 2016 hingga 5 Juni 2016 di 22 kota. Dana yang terkumpul dari hasil penjualan kantong plastik merupakan dana publik yang nantinya digunakan untuk kegiatan pengelolaan sampah. Dengan penerapan kebijakan ini diharapkan dapat mengurangi penggunaan kantong plastik di Indonesia, seperti pada negara-negara lain yang sudah menerapkan kebijakan ini sebelumnya.

Plastic is used in many forms in day-to-day life. Since Plastic is non-biodegradable, landfills do not provide an environment friendly solution. Hence, there is strong need to utilize waste plastic. This creates a large quantity of garbage every day which is unhealthy and pollutes the environment. In present scenario solid waste management is a challenge in our country. The production of solid waste is increasing day to day and causes serious concerns to the environment. In this study, the recycled plastics are used in the concrete as a partial replacement of fine aggregate in concrete. The main purpose of this study is to investigate the mechanical properties of concrete such as workability, compressive, flexural and split tensile strengths of concrete mixes with partial replacement of conventional fine aggregate with aggregate produced from plastic waste. The use of plastic aggregate as replacement for fine aggregate enhances workability and fresh bulk density of concrete mixes. The mechanical properties of concrete such as compressive, flexural, and tensile strengths of concrete reduced marginally up to 10% replacement levels.
