Pengaruh ukuran partikel arang dari limbah tutup botol plastik terhadap kualitas briket

Abstract

The amount of plastic waste increases with the increase in plastic use, especially in the food industry. Plastic waste is waste that is very difficult to decompose and takes a long time to spoil. Plastic bottle caps are a type of polypropylene (PP) plastic which is recommended to be used only once. The research objective was to determine the effect of particle size on the briquette characteristics of plastic bottles based on the proximate analysis. The proximate analysis carried out was moisture content, ash content, volatile matter, fixed carbon, and calorific value. The research design used was a burning temperature of 450 °C, a burning time of 60 minutes, and particle sizes of 40, 60, and 100 mesh. The results showed that the particle size of 40 mesh had the best characteristics, namely water content of 0.5±0,05%, ash content of 2±0,25%, volatile matter content of 15±0,51%, bound carbon content of 82.5±0,32%, and a heating value of 9,982.779±240,017 cal/gram. Based on the results of the proximate analysis, it can be concluded that a particle size of 40 mesh can improve the quality of briquettes compared to 100 mesh.

Briquettes Optimization of Palm Shell Waste and LDPE Plastic based on Particle Size and Compressive Strength as Alternative Fuels

“…High-energy briquettes have a calorific value of 26,5-33,8 MJ/kg, which is significantly comparable to the maximum value reported for high-energy coal of 27 MJ/kg, while the compressive strength is 0,7 MPa [6]. Research conducted [7] by utilizing plastic bottle caps from home industrial health drink lids (infused water) and tapioca flour shows that at 40 mesh particle size, best properties i.e. moisture content 0,5 ± 0,05%, ash content 2 ± 0,25%, volatile content 15 ± 0,51%, combined carbon content 82,5 ± 0,32%, and 9.982,779 ± 240,017 calorific value in cal/gr.…”

“…Based on the close-up analysis result of 9.982,779 ± 240,017 cal/gr. From this, it can be concluded that the particle size of 40 mesh can improve the briquette quality compared to 100 mesh [12]. The next research is to determine the emission of carbon monoxide (CO) and the combustion rate of briquettes mixed with rice husk and teak sawdust and their effect on the grain size of the briquettes.…”

Utilization of LDPE Plastic Waste, Coconut Shell and Coconut Husk as Basic Material for Briquettes with Tapioca Starch Adhesive

“…First, weigh 1 gram of the bio-briquette sample, then place it in the cup. The cup filled with bio-briquette samples was put into the furnace with a temperature of 750 ± 20 ℃ for 7 minutes, after which the sample was cooled in a desiccator and weighed; the volatile matter content is calculated by the following equation (Ningsih et al, 2020).…”

“…Fixed carbon content is a parameter of bio-briquette quality. The fixed carbon content indicates the combustible carbon content after the expulsion of volatile materials (Ningsih et al, 2020). The level of fixed carbon will significantly affect the ignition of bio-briquettes.…”

Studi Awal Pembuatan Briket dari Campuran Sampah Botol Jenis PET dan Bahan Sintesis Dengan Perekat Lumpur Sidoarjo

“…Diverifikasi produk pemanfaatan plastik untuk bahan campuran briket merupakan salah satu alternatif pengoptimalan sampah plastik atau limbah lainnya. Briket sampah botol plastik dan bahan sintesis diuji nilai kalor, kadar air, kadar abu, kadar zat menguap dan kadar karbon terikat untuk mengetahui pengaruh bahan plastik dan bahan sintesis terhadap kualitas briket (Ningsih et al, 2020) Berdasarkan Tabel 2. Pengmatan uji nilai kalor briket campuran sampah botol plastik dan bahan sintesis dengan perekat lumpur Sidoarjo menggunakan perbandingan komposisi bahan 50 gr : 30 gr : 20 gr, serta perbandingan komposisi perekat kanji 100 gr : 8 gr menghasilkan nilai kalor sebesar 19,75 MJ/kg atau apabila dikonversi satuan kalori sebesar 4717 cal/gr.…”
