Industrial Plantation Forest of Acacia mangium for pulp industry in Indonesia has declined its productivity due to a decrease in the quality of soil on the second cycle and thereafter. Therefore, the alternative raw material for pulp has to be found as a substitute for Acacia mangium. Research on the various ages of Acacia crassicarpa (4; 5 and 6 years old) as the pulp raw material has been done. Pulp was prepared using the kraft process. The optimum cooking condition with target Kappa Number of 15 ± 1 was obtained at 20-22% active alkali, 30% sulfidity, temperature of 165ºC, liquor ratio 1:4 and H factor of 1300. Pulp was then bleached using ECF (Elemental Chlorine Free) process with the sequence of ODEDED and XDEDED. Results showed that pulp yield was high enough and meet the standard requirement according to SNI 6107:2009, Pulp Kraft Putih Kayudaun (LBKP). hollocellulose content of Acacia crassicarpa (79,99-80,87%) and α cellulose content (43,33-48,62%) were higher compared to those of Acacia mangium (<79% and <43%) respectively, while lignin and extractive contents were significantly low. It was found that Acacia crassicarpa of 5 years old resulted in better bleached kraft pulp compared to those of 4 and 6 years old. It is concluded that Acacia crassicarpa has a good prospect to be developed in  Industrial Plantation Forest as raw material for pulp.

Industri pulp Indonesia saat ini memiliki masalah dalam penyediaan bahan baku kayu Acacia mangium, karena serangan penyakit tanaman dan hama. Hal ini harus diantisipasi melalui bahan baku alternatif pengganti Acacia mangium, spesies Eucalyptus pellita dipilih karena lebih tahan terhadap hama dan penyakit. Penelitian ini dilakukan untuk mengetahui karakteristik kualitas pulp kraft putih E. Pellita. Penelitian pembuatan pulp kertas dilakukan dengan proses kraft dengan bahan baku A. mangium dan E. pellita. Pemasakan dilakukan dengan variasi alkali aktif 16-20%, sulfiditas 28,7%, pada suhu 165 °C, rasio larutan pemasak terhadap kayu 3,5:1 dan faktor H 1.022. Pemutihan pulp dilakukan dengan proses ECF (Elemental Chlorine Free) dengan tahapan OD0EoD1. Karakteristik pulp kraft hasil pemasakan A. mangium lebih tinggi pada parameter rendemen tersaring, bilangan kappa dan viskositas dibandingkan dengan E. pellita. Penggunaan alkali aktif 16% pada pemasakan A. mangium lebih rendah dari  E. pellita (18%), namun kualitasnya dapat memenuhi spesifikasi kualitas pulp kraft putih sesuai SNI 6107:2015 (Pulp Kraft Putih Kayu daun) pada parameter derajat giling, derajat putih dan sifat fisik.  Karakteristik pulp kraft putih A. mangium lebih tinggi pada parameter derajat giling, derajat putih dan sifat fisik dibandingkan dengan E. pellita. Namun demikian E. pellita berpotensi untuk dikembangkan di Hutan Tanaman Industri sebagai bahan baku pulp.Effect of Active Alkali on Characteristic of Acacia mangium and Eucalyptus pellita Bleached Kraft PulpAbstractThe Indonesian pulp industry currently has problems in supplying Acacia mangium wood raw materials, due to plant disease and pest attacks. This could be anticipated through alternative raw materials to substitute Acacia mangium, the Eucalyptus pellita species chosen because it is more resistant to pests and diseases. This study was conducted to determine the quality characteristics of E. Pellita bleached kraft pulp. The research on making paper pulp using A. mangium and E. pellita was carried out by means of the kraft process. The cooking was carried out with a variation of 16-20% active alkali, 28.7% sulfidity, at a temperature of 165°C, a liquor to wood ratio of  3.5:1 and an H factor of 1.022. The bleaching of the pulp has been carried out using the ECF (Elemental Chlorine Free) process with the OD0EoD1 stage. Characteristics of kraft pulp from A. mangium cooking were higher in the screening yield, kappa number and viscosity compared to E. Pellita. The use of 16% active alkaline in cooking of  A. mangium is lower than E. pellita (18%), but the quality can meet the quality specifications of white kraft pulp according to SNI 6107: 2015 (White Kraft Leaf Wood Pulp) on the parameters of milled degree, whiteness and properties. The characteristics of A. mangium white kraft pulp were higher in parameters of grind degree, whiteness and physical properties compared to E. pellita. However, E. pellita has the potential to be developed in Industrial Plantation Forests as raw material for pulp.

Oil Palm Trunk (OPT) is a non-wood cellulosic raw material which is not yet widely utilized in pulping and papermaking. Research on the utilization of abundant Oil Palm Trunk (OPT) from Sabah (Malaysia) and Lebak (West Java Province) for pulp production was carried out using kraft and soda anthraquinone processes with active alkali (AA) of 13-17%. The raw material was chipped and depithed as pretreatment. Bleaching of pulp was carried out using Elemental Chlorine Free (ECF) process. Analysis of raw material covered physical and chemical properties, and fiber morphology. Both OPT fibers were classified into the moderate fiber length (1.05-1.37 mm). Sabah OPT were very bulky with the chips pile density of 102.16 kg/m3 and 62.91 kg/m3 for undepithed and depithed OPT, respectively. The physical properties of OPT pulps were comparable to that of Acacia mangium pulp. With respect to the bleachability and physical properties, pulping of Lebak OPT using kraft or soda-anthraquinone process with AA of 15% were considered as optimum condition. Depithing on Sabah OPT with high pith content could increase physical properties of pulp. ODEoDnD bleaching sequence on pulps from Sabah OPT gave satisfactory results with respect to the physical properties. Since Sabah OPT had a high pith content, the yields of bleached pulp were relatively low (24.67-26.73%). However, the physical properties of the undepithed and depithed Sabah OPT bleached pulp were higher compared to those of the SNI of Leaf Bleached Kraft Pulp (LBKP).Keywords: depithing, Elemental Chlorine Free, bleached pulp, physical properties, LBKP Pengaruh Variabel Proses Pulping dan Pemutihan Elemental Chlorine Free pada Kualitas Pulp Batang Kelapa SawitAbstrakBatang Kelapa Sawit adalah bahan baku selulosa non-kayu yang belum banyak digunakan dalam pembuatan pulp dan kertas.

This study aimed to evaluate and compare the relationship between chemical properties, energy efficiency, and emissions of wood and pellets from madroño Arbutus xalapensis Kunth, tázcate Juniperus deppeana Steud, and encino colorado Quercus sideroxyla Humb. & Bonpl. in two gasifiers (top-lit-up-draft (T-LUD) and electricity generation wood camp stove (EGWCS)) in order to determine the reduction of footprint carbon. In accordance with conventional methodologies, we determined the extracts and chemical components (lignin, cellulose, holocellulose), and the immediate analyses were carried out (volatile materials, fixed carbon, ash content and microanalysis of said ash), as well as the evaluation of emission factors (total suspended particulate matter (PM2.5), CO, CO2, CH4, black carbon (BC), elemental carbon (EC), and organic carbon (OC)). The results were statistically analyzed to compare each variable among species and gasifiers. The raw material analyzed showed how the pH ranged from 5.01 to 5.57, and the ash content ranged between 0.39 and 0.53%. The content values of Cu, Zn, Fe, Mg, and Ca ranged from 0.08 to 0.22, 0.18 to 0.19, 0.38 to 0.84, 1.75 to 1.90, and 3.62 to 3.74 mg kg−1, respectively. The extractive ranges from cyclohexane were 2.48–4.79%, acetone 2.42–4.08%, methanol 3.17–7.99%, and hot water 2.12–4.83%. The range of lignin was 18.08–28.60%. The cellulose content ranged from 43.30 to 53.90%, and holocellulose from 53.50 to 64.02%. The volatile material range was 81.2–87.42%, while fixed carbon was 11.30–17.48%; the higher heating value (HHV) of raw material and pellets presented the ranges 17.68–20.21 and 19.72–21.81 MJ kg−1, respectively. Thermal efficiency showed statistically significant differences (p < 0.05) between pellets and gasifiers, with an average of 31% Tier 3 in ISO (International Organization for Standardization) for the T-LUD and 14% (ISO Tier 1) for EGWCS, with Arbutus xalapensis being the species with the highest energy yield. The use of improved combustion devices, as well as that of selected raw material species, can reduce the impact of global warming by up to 33% on a cooking task compared to the three-stone burner.

Pineapple waste accounts for a significant part of waste accumulated in landfill which will further contribute to the release of greenhouse gases. With the rising pineapple demands worldwide, the abundance of pineapple waste and its disposal techniques are a major concern. Exploiting the pineapple waste into valuable products could be the most sustainable way of managing these residues due to their useful properties and compositions. In this review, we concentrated on producing useful products from on-farm pineapple waste and processing waste. Bioenergy is the most suitable option for green energy to encounter the increasing demand for renewable energy and promotes sustainable development for agricultural waste. The presence of protease enzyme in pineapple waste makes it a suitable raw material for bromelain production. The high cellulose content present in pineapple waste has a potential for the production of cellulose nanocrystals, biodegradable packaging and bio-adsorbent, and can potentially be applied in the polymer, food and textile industries. Other than that, it is also a suitable substrate for the production of wine, vinegar and organic acid due to its high sugar content, especially from the peel wastes. The potentials of bioenergy production through biofuels (bioethanol, biobutanol and biodiesel) and biogas (biomethane and biohydrogen) were also assessed. The commercial use of pineapples is also highlighted. Despite the opportunities, future perspectives and challenges concerning pineapple waste utilisation to value-added goods were also addressed. Pineapple waste conversions have shown to reduce waste generation, and the products derived from the conversion would support the waste-to-wealth concept.
