The paper industry generates solid waste such as wastewater sludge and paper mill rejects. The rejects from recycled paper processing are varies from 5 % to 25 % dependent on the recovered fiber quality and process used in the mill. The composition of the rejects is consisted of fiber bundles, plastics pieces, foils and polystyrene containing large quantities of plastics. One of the limitations of solid waste for energy is bulky and high moisture content which is difficult to be stored, transported, and utilized. To overcome this limitation, it is needed a solidification process. Pelletizing of paper mill solid waste is one of solidification processes to ease in storing, handling, and transporting of solid waste. Experiment on solid wastes utilization in the pellet form as fuel has been carried out. Solidification process of paper mill solid waste is consisted of drying, shredding and  pelletizing processes of solid waste. Pellet of paper mill solid waste and coal and pellet of combination of rejects waste were analyzed for their proximate, mineral content of ash and ash fusion temperature (AFT) to see slagging and fouling potency. The results shows that paper mill reject contain high calorific value of 5,987 calorie/gram and low content of sulphur and ash. Ash has low content of total alkali (Na2O and K2O) and high initial deformation temperature (IDT) of 1,193oC. Mixed of 95% coal and 5% pellet of reject waste has low content of total alkali (Na2O and K2O) and high initial deformation temperature (IDT) of 1,315oC. The result  indicates low slagging and fouling potency of reject waste when it is utilized as a boiler fuel.Keywords: solid waste, sludge, rejects, pellet, fuel, slagging, fouling  ABSTRAK Industri kertas menghasilkan limbah padat seperti limbah lumpur dan limbah reject. Jumlah limbah reject dari pengolahan kertas daur ulang bervariasi dari 5% sampai 25% tergantung pada kualitas serat dan proses yang digunakan di pabrik. Komposisi limbah reject terdiri dari gumpalan serat, potongan plastik dan foil. Salah satu keterbatasan dari limbah padat untuk energi adalah ruah dan kadar air-nya tinggi yang menyulitkan dalam penyimpanan, transportasi, dan penggunaannya. Untuk mengatasi keterbatasan ini diperlukan proses solidifikasi. Pembuatan pellet dari limbah padat industri kertas merupakan salah satu proses solidifikasi untuk memudahkan dalam penyimpanan, penanganan, dan pengangkutan limbah padat. Penelitian pemanfaatan limbah padat dalam bentuk pelet sebagai bahan bakar untuk energi telah dilakukan. Proses solidifikasi limbah padat pabrik kertas terdiri dari proses pengeringan, proses pencacahan dan proses pembuatan pellet. Pellet limbah padat industri kertas dan campuran dari batubara dan pellet limbah reject diuji untuk analisis proksimat, kadar mineral abu, kadar abu dan suhu fusi abu (AFT) untuk mengetahui potensi slagging dan fouling. Hasil menunjukkan bahwa limbah reject industri kertas mengandung nilai kalor tinggi 5.987 kalori/gram dan rendah sulfur dan abu. Abu mengandung alkali total (Na2O dan K2O) rendah dan suhu deformasi awal tinggi (IDT) yaitu 1.193oC. Campuran dari batubara 95% dan pellet limbah reject 5% mengandung alkali total (Na2O dan K2O) rendah dan suhu deformasi awal tinggi (IDT) yaitu 1.315oC. Hal ini menunjukkan potensi slagging dan fouling rendah bilamana limbah reject digunakan sebagai bahan bakar boiler.Kata kunci: limbah padat, lumpur, reject, pelet, bahan bakar, slagging, fouling

The performance of modified anaerobic hybrid baffled (MAHB) bioreactor treating recycled paper mill effluent (RPME) was investigated at various organic loading rates (OLR) of 1, 2, 3 and 4 g COD/ L.day. The bioreactor was operated continuously at constant hydraulic retention time (HRT) of a day without effluent recycled and chemicals adjustment/addition. Throughout 70 days of operation, a maximum removal efficiency up to 97% of chemical oxygen demand (COD) and 98% of volatile fatty acid, biogas production of 12.51 L/day equivalent to methane (CH4) yield of 0.108L CH4/ g COD and a stable pH system between 6.6 to 7.2 were achieved. Additionally, alkalinity of the bioreactor system shows a stable profile that indicates the whole system was well buffered with a quit high degradation of volatile solid (VS) up to 18%. These results indicated that MAHB bioreactor has been successfully treated RPME at various OLR.

Calcium precipitation can have a number of effects on the performance of high-rate anaerobic performance including cementing of the sludge bed, limiting diffusion, and diluting the active biomass. The aim of this study was to observe the influence of precipitation in a stable full-scale system fed with high-calcium paper factory wastewater. Granules were examined from an upflow anaerobic sludge blanket reactor (volume 1,805 m3) at a recycled paper mill with a loading rate of 5.7–6.6 kgCOD.m−3.d−1 and influent calcium concentration of 400–700 gCa.m−3. The granules were relatively small (1 mm), with a 200–400 μm core of calcium precipitate as observed with energy dispersive X-ray spectroscopy. Compared to other granules, Methanomicrobiales not Methanobacteriales were the dominant hydrogen or formate utilisers, and putative acidogens were filamentous. The strength of the paper mill fed granules was very high when compared to granules from other full-scale reactors, and a partial linear correlation between granule strength and calcium concentration was identified.
