Abstract. The combination of anaerobic digestion and pyrolysis technologies could be a novel energy-biochar production system to maximize energy and nutrient recovery from pulp and paper mill sludge. Herein, the life-cycle energy production and emissions reduction of sludge treatment from a typical pulp and paper mill were investigated, in which alternative uses of biogas for industrial or household application, in different regions of the world, were assessed. The three scenarios considered for different end-uses of biogas are: (A) biogas for vehicle fuel in the transportation sector in Sweden, (B) biogas for heat and electricity in the power sector in Brazil, and (C) biogas for cooking in households in China. The results of Environmental Life-Cycle Assessment (E-LCA) show that for all these three scenarios, the use of biogas and pyrolysis gas contributes most to emissions mitigation, while the dewatering and drying processes carried out on the sludge, contribute the most to the environmental emissions. Addition of biochar to the soil, contributes significantly to a reduction in global warming by sequestering carbon in the soil. Compared to scenarios B and C, Scenario A, in which biogas substitutes gasoline in transportation, and heat from combusted pyrolysis gases is used for district heating in Sweden, demonstrates the highest environmental performance for all the evaluated impact categories.

From the regulatory perspectives, pulp and paper mill sludge management as a environmental issue is significant. The restricted of imported recycle paper is a problem for the pulp and paper industry. Therefore a research was conducted to determine utilization potential of the WWTP sludge from paper industry in Indonesia as raw material for chipboard based on the characteristics of the sludge. The environmental aspects evaluation also has been cundected TCLP test and toxicology LD50 to determine whether the sludge waste category B3. The test results showed that the levels of alpha cellulose sludge is high (45-84%). Primary Sludge from virgin pulp contains high alpha cellulose (76-84%), ash content (3-14%), and the fines are quite low (30-34%). Potential of primary and final sludge to be used as raw material for chipboard. However, the primary sludge is generally recycled so that the final sludge are more preferable to be utilized. The results of FT-IR spectra analysis showed that the dominant chemical components in the sludge are cellulose. Fiber and fines content in line with the observation using SEM. Based on the results of the TCLP test and LD50, it is known that the sludge contains heavy metals, inorganic and organic are stable, so it is safe for the environment and can be utilized. Thus sludge has potential as a raw material for chipboard.ABSTRAKPengelolaan limbah sebagai isu lingkungan penting untuk dilakukan, terutama dari perspektif regulasi.  Adanya larangan impor kertas daur ulang, merupakan masalah bagi industri pulp dan kertas.  Oleh karena itu dilakukan penelitian untuk meneliti potensi pemanfaatan sludge IPAL dari industri kertas di Indonesia sebagai bahan baku pembuatan chipboard berdasarkan karakteristik sludge.

Hasil analisa spektra FT-IR sludge menunjukkan bahwa komponen kimia yang dominan dalam sludge adalah selulosa. Data kandungan serat dan kandungan fines sejalan dengan pengamatan menggunakan SEM. Berdasarkan hasil uji TCLP dan LD50, diketahui bahwa sludge mengandung logam berat, inorganik dan organik yang bersifat stabil, sehingga aman terhadap lingkungan dan dapat dimanfaatkan. Dengan demikian sludge mempunyai potensi sebagai bahan baku pada industri karton chipboard. Kata kunci : Chipboard, industri kertas, LD50, sludge IPAL, TCLP
