Abstract

Utilization of reject plastic pellet of paper mill which is waste paper as the raw material has been carried out. Making of reject plastic pellet was consisted of wet shredded process of reject using shredded machine, separation process of plastic and fiber with filtration process, and drying process of wet shredded plastic using centrifugal drainer machine and sun-drying. Dried shredded reject plastic was then formed plastic pellet using pellet machine. Plastic pellets produced has diameter of around 10 mm and a length of about 10-15 mm. Plastic pellets were analyzed for proximate analysis (moisture, ash, volatile matter and fixed carbon contents). In addition, it was also tested for calorific value, sulfur content, ash mineral content and the ash fusion temperature (AFT). The results indicate that the reject plastic pellets have a high calorific value (7,207-8,730 cal/g), low sulfur content (0.14 to 0.17%), low ash mineral content, and the Ash Fusion Temperature (AFT) above the operating temperature of the boiler (900oC). Reject plastic pellets in the amount of 4.25% of production capacity could potentially be used as a coal substitution for fuel boiler of paper mill with a low propensity of slagging and fouling in the boiler.Keywords: coal, paper mill, pellets, plastic, reject, fuel   ABSTRAKPenelitian pemanfaatan pelet plastik rejek industri kertas berbahan baku kertas bekas telah dilakukan.

The study of the organic fertilizer pellet from anaerobic digestion residue of paper mill sludge has been conducted. Study was divided into: characterization of biological sludge, anaerobic digestion process to obtain a precipitate residual sludge, organic fertilizer pellets production, and economic analysis. Pilot scale anaerobic digestion process is done in a paper industry at pH of 5.5 to 6.0, alkalinity of 2000-2500 mg/L and a residence time of 4 days with feed solids content of 0.6%. Stages of organic fertilizer pellets production were dewatering, drying and pellets formation. Pellets were made with a mixture of rice husk ash additive powder of 5-10%. The results showed that the residual sludge from anaerobic digestion process had a solid content (TS) from 2.0 to 4.5%. The process of dewatering of residue sludge and the drying process can increase the levels of solids each up to 26-29% and 80%. Pellets that was produced meets the requirements as organic fertilizer or soil conditioner according to Indonesia National Standard   (SNI) 7847: 2012 that is intended for industrial timber estates (HTI). Based on material balance calculations for industrial scale, biological sludge digestion capacity of 200 tonnes a day with a TS content of 1%, resulting in digestion sludge residue as much as 24 tonnes/ day with a TS content of 3% .From the sludge residue can be made fertilizer pellets with TS of 80.5% as much as 710 kg/day. Economic analysis results indicate that the Pay Back Period was 3.9 years with the Break Even Point (BEP) of 48%.Keywords: anaerobic digestion, biological sludge, sludge residue, organic fertilizer pellet ABSTRAKPenelitian pembuatan pelet pupuk organik dari residu digestasi anaerobik lumpur biologi industri kertas telah dilakukan.

Abstract

The Indonesian Government has set the regulations regarding guidelines for the use of archival paper or permanent document. The paper must meet the specifications of SNI ISO 11108. The problem of archival paper production in Indonesia is difficulty in meeting the quality requirements of permanence and durability. Paper producers in Indonesia have tried to make an archival paper using cotton linter as raw material but it still did not meet the quality requirements of permanence, especially for pH and alkaline reserve parameters. The laboratory archival papermaking experiments using guar gum and high dosage of CaCO3 has been carried out. The scope of experiments: the determination of the characteristics of cotton linter; the determination of optimum freeness of cotton linter, optimum dosage of CaCO3, and optimum dosage of guar gum; the observation of cotton linter pulp and guar gum interaction; the quality testing of archival paper from cotton linter pulp. The results showed that guar gum is effective to improve the folding endurance of paper containing high CaCO3, at least 7.5%. Archival paper produced meets the quality requirements of SNI ISO 11108.Keywords: Archival paper, CaCO3, cotton linter pulp, guar gum   ABSTRAK Pemerintah telah menetapkan peraturan mengenai pedoman penggunaan kertas untuk arsip atau dokumen permanen.

Abstract

Waste Water Treatment Plant (WWTP) of paper mills generates biological sludge containing organic compounds such as microbial biomass in the range of 60-90%. The sludge is voluminous and difficult dewatered causing problems during handling and utilization. Microbial cell wall disintegration using thermo-alkaline and sonication disrupt microbial cell walls so sludge handling and utilization is easier for further use. Cell wall disruption of biological sludge pre-treatment using thermo-alkaline, sonication  and  combination  of  both  treatments  has  been  conducted.  Thermo-alkaline  treatment  was carried out for 24 hours with temperature variations (20oC, 37oC, 50oC) and pH (9, 10, 11); sonication treatment  was  performed  at  high  frequency  (30  ±  10  kHz)  with  a  variation  of  time  (15,  30,  and  45 minutes), and the combination of both treatments was performed at the optimum conditions respectively. The effectiveness of treatment was evaluated based on the increase of soluble COD (CODf) and ratio of CODf /CODT with univariate statistical test (SPSS 16.0). The results showed that the thermo-alkaline treatment is more effective than sonication and combination treatment. The best condition was obtained when sludge treated with thermo-alkaline treatment at pH 10 and temperature 37°C, CODf was increased 439.91%, with ratio of CODf/CODT 0,128.Keywords: biological sludge, cell disintegration, thermo-alkaline, sonication, CODfABSTRAKInstalasi Pengolahan Air Limbah (IPAL) industri kertas menghasilkan lumpur biologi yang mengandung senyawa organik berupa biomassa mikroba berkisar 60-90%. Lumpur tersebut bersifat voluminousdan sulit dihilangkan airnya sehingga menimbulkan masalah pada penanganan dan pemanfaatannya. Perlakuan termo-alkali dan sonikasi merupakan metode disintegrasi sel terhadap lumpur biologi yang dilakukan untuk memecah dinding sel mikroba sehingga dapat lebih mudah dalam penanganan dan pemanfaatan selanjutnya. Penelitian termo-alkali, sonikasi, dan gabungannya terhadap lumpur biologi telah dilakukan. Perlakuan termo-alkali dilakukan selama 24 jam dengan variasi suhu (20oC, 37oC, 50oC) dan pH (9, 10, 11); perlakuan sonikasi dilakukan pada frekuensi tinggi (30 ± 10 kHz) dengan variasi waktu (15, 30, dan 45 menit), dan perlakuan gabungan termoalkali dan sonikasi dilakukan pada kondisi optimum masing-masing. Efektivitas perlakuan dievalusi berdasarkan peningkatan COD terlarut (CODf) dan rasio CODf /CODT dengan uji statistik univariate(SPSS 16.0). Hasil percobaan menunjukkan bahwa perlakuan termo-alkali lebih efektif dibandingkan dengan perlakuan sonikasi dan gabungannya. Kondisi terbaik perlakuan termo-alkali adalah pada pH 10 dan suhu 37oC dengan peningkatan CODf 439,91% dengan rasio CODf /CODT 0,128.Kata kunci : Lumpur biologi, disintegrasi sel, termo-alkali, sonikasi, CODf
