Konsumsi kertas bekas di industri kertas Indonesia mencapai 6.598.464 ton/tahun dan menghasilkan hydropulper reject sebesar 5-10% dari kertas bekas yang digunakan. Penelitian pirolisis hydropulper reject dari industri kertas untuk produksi bio-oil telah dilakukan. Tipikal limbah hydropulper reject terdiri dari 20% serat dan 80% plastik (High Density Polyethylene, HDPE >90%). Bahan padat tersebut berpotensi dikonversi menjadi bahan bakar minyak melalui proses pirolisis. Penelitian ini bertujuan mengevaluasi pirolisis pelet hydropulper reject untuk produksi bio-oil sebagai bahan bakar minyak. Setelah dipisahkan dari logam, hydropulper reject dikeringkan, dicacah, dan dibentuk menjadi pelet berdiameter 10 mm dan panjang 20-30 mm. Nilai kalor pelet hydropulper reject mencapai 29,30 MJ/kg (dried based, db) dengan kadar zat terbang 84,84% (db). Pelet hydropulper reject dipirolisis dengan reaktor kombinasi pembakaran-pirolisis. Produk yang dihasilkan berupa bio-oil mampu bakar sebanyak ±40% bahan baku dengan nilai kalor 77,79 MJ/kg. Perkiraan listrik yang dapat dihasilkan dari pemanfaatan syngas sebesar 1,08 kWh/kg hydropulper reject.Kata kunci: hydropulper reject, pirolisis, bio-oil, syngas, listrikProduction of Oil Fuel From Pyrolysis of Hydropulper Reject Pellet from Paper IndustryAbstract Waste paper consumption in Indonesian paper industries reached 6,598,464 tons/year and produced hydropulper reject about 5-10% of waste paper. Pyrolysis of hydropulper reject from the paper industry for bio-oil production has been investigated. Hydropulper reject consists of 20% fiber and 80% plastic (High Density Polyethylene, HDPE>90%). This solid material has potential to be converted into oil fuel through pyrolysis. This study aims to investigate the pyrolysis of hydropulper reject pellets for bio-oil as fuel oil production. After being separated from the metals, hydropulper reject was dried, shredded, and shaped into pellets with 10 mm diameter and 20-30 mm length. The pellets had calorific value of 29.30 MJ/kg (dried based, db) with volatile matter 84.84% (db). The pellets were pyrolized with a combustion-pyrolysis combination reactor. The product was combustible bio-oil as much as ±40% of feedstock and had calorific value of 77.79 MJ/kg. Estimated electricity generated from syngas utilization about 1.08 kWh/kg.  Keywords: hydropulper reject, pyrolysis, bio-oil, syngas, electricity

In recent years, many researches focused on the polymer materials to study the characteristics and to enhance the mechanical properties of the nanocomposites in order to understand the factors which lead to the desired dispersion of nanoclay in the polymer matrix. The samples used in this work were prepared through melt compounding, using high-density polyethylene and organo-modified clay of montmorillonite (MMT). During manufacturing of MMT/HDPE nanocomposites, a silane modifier and polyethylene grafted with maleic anhydride (compatibilizer) were added to get good surface finish and to act as bonding agent respectively. In addition, the compatibilizer will help in attaining better intercalation. Using a Plastograph-Mixer through twin-screw extruder, the high density polyethylene and different weight percentages (0, 1, 2, 3, 4 wt. %) of MMT are mixed and subsequently the composite is produced in the form of solid material. ASTM standard specimens for various tests are produced using injection molding machine with respective dies. The prepared experimental specimens for various tests like tensile, flexural, impact and shore-hardness are tested for its respective strengths. From this investigation, it is concluded that the addition of MMT nanoclay in HDPE has significantly influenced the mechanical properties of the composites.

The waste corrugated paper was grinded to paper pulp first, and then the paper pulp was used to prepare the foamed waste paper pulp/high density polyethylene（HDPE）composites by compression molding with HDPE. The Rosand double-barrel capillary rhepmeter was used to research the influences of the blowing agent AC(Azodicarbonamide) content，waste paper pulp content，temperature and different blowing agent on the melt of the composites. Scanning electron microscopy（SEM）was also used to observe the effects of different contents of AC and waste paper pulp on the cell morphologies.The results showed that: when the shear rate up to 600 S-1，the melt performs of the foamed waste paper pulp/ HDPE composites were pseudoplastic flow, and turn up wall slip phenomenon. The viscosity of melt was significantly reduced with the content of AC increased, but it increased with the content of the waste paper pulp increased. When the shear rate reduced to 275 S-1 or below, the viscosity of melt reduced as the temperature riased; while when the shear rate went up to 275 S-1 or high, the viscosity of melt increased as the temperature riased. When the shear rate reduced to 325 S-1 or below, the melt of endothermic blowing agent （NaHCO3）showed the highest viscosity; when the shear rate went up to 325 S-1 or high, the melt of exothermic blowing agent AC shows the highest viscosity. The number of cell increased and size of cell became smaller with the AC content increased , but the number of cell reduced and the size of cell became larger with the content of waste paper pulp increased observing by SEM.

Paper mill using recycle fiber as raw material produces reject containing fiber and plastic. The reject was identified by means of sorting. Reject pellet was prepared by drying, followed by shredding, and pellets molding. It was analyzed for its proximate composition (moisture, ash, volatile matter and fixed carbon). Calorific value, sulfur content, ash mineral content, and ash fusion temperatures were also tested. The results showed that reject consists of 50.75% fiber and 49.25% plastic of which is >99% High Density Polyethylene (HDPE). Reject contains a high calorific value of about 7000 cal/g which could potentially be used as fuel. Coal boiler fuel containing 5-50% reject pellet shows no indication of slagging and fouling in the boiler.Keywords: reject, pellet, coal, calorific value, fuel ABSTRAKIndustri kertas berbahan baku kertas bekas menghasilkan reject yang mengandung serat dan plastik.

Bio Oil

The current consumption of fuel oil, especially gasoline and diesel oil, is increasing. Along with the decline in production, national oil production activities encourage efforts to find alternative fuels as a substitute for oil-based energy supplies. Bio-oil is an environmentally friendly alternative fuel for diesel that can be used as fuel. In this study, the raw materials were palm oil empty bunches and polypropylene plastic waste. The purpose of this study was to determine the effect of the ratio of raw material for oil palm empty fruit bunches and polypropylene, the effect of co-pyrolysis temperature on the yield of bio-oil and determine the characteristics of the resulting bio-oil. This study used the variable ratio of oil palm empty fruit bunches and polypropylene (100:0, 80:20, 70:30 and 60:40) and co-pyrolysis temperature (400, 450, 500 and 550 °C). The results showed that the highest yield of bio-oil was obtained, namely 41.6% with a ratio of EFB: PP (80:20) at temperature of 450 °C. The characterization of the product obtained was density of 0.891 g/ml,  viscosity of 4.18 cSt,  pH of 3.38 and  calorific value of 43.2 MJ/kg.
