Production and Characterization of Pulp from Banana Pseudo Stem for Paper Making via Soda Anthraquinone Pulping Process

The need for pulp and paper currently in the whole world has become shooting up massively. The generation of the pulp, as well as paper from woody materials, has a challenge due to deforestation, huge chemical and energy consumptions. Now, an alternative source for paper is lignocelluloses wastes, because of low cost, low energy, and chemical consumption. Among them, the banana pseudostem was best for the input of pulp and paper production. This investigation was on the production and characterization of pulp from Banana Pseudo Stem for Paper Making via Soda Anthraquinone pulping process. The amount of cellulose (41.45%), ash (12.4%), hemicellulose (23.37%), extractive (12.72%), and lignin (10.46%) contents were obtained at the initial compositional evaluation of the pseudostem. It has excellent fiber length (1.75mm), fiber diameter (22.15μm), an acceptable Runkle ratio (0.55), and flexibility coefficient (159.64). The effect of temperature (130,140 and 150 °C), cooking time (45, 60, and 75 minutes), the concentration of soda (10, 12.5, and 15%), were examined. The maximum pulp yield and kappa number was 36.7% and 22.8 respectively obtained at 10% of soda concentration, at 150 °C, and 63 minutes of cooking time from oven-dried raw material. The produced paper from the banana pseudostem has a tensile index, tearing index, smoothness, and porosity were 78.75 Nm/g, 19.1 mN.m2/g, 500-530μm, and 50 sec/100ml air respectively. This study indicates that high strength mechanical property and good surface properties paper can be produced from banana pseudostem pulp with a more environmentally friendly pulping process.

Effect of biomass-based carbon capture on the sustainability and economics of pulp and paper production in the Nordic mills

Bioenergy with carbon capture and storage (BECCS) is one of the key negative emission technologies (NETs). Large-scale implementation of BECCS has been criticized of the associated increase in land use. The existing large Nordic pulp and paper production units enable BECCS deployment without additional land use, as they currently release large amounts of bio-based carbon dioxide (CO2). The application of BECCS in pulp mills has been found technically feasible in earlier studies. This study explores key factors that affect the propensity to invest in BECCS in different types of existing European pulp and paper mills. The results give fresh understanding on the effects of BECCS on the market price of pulp and paper products and the required level of incentives. Based on statistical data, the marginal carbon dioxide credit (€ per ton CO2) to make BECCS profitable was derived. The results show that the required level of credit greatly depends on the mill type and details and that the feasibility of BECCS does not clearly correlate with the economic performance or the measured efficiency of the mill. The most promising mill type, a market kraft pulp mill, would find BECCS profitable with a credit in the range of 62–70 €/tCO2 and a credit of 80 €/tCO2 would decrease pulp production costs by 15 €/tproduct on average if 50% of CO2 emissions was captured. The EU Emission Trading System (ETS) is the main policy instrument to achieve the climate targets related to fossil energy use, but does not yet contemplate bio-based emissions.

The Degree of Contribution of Digital Transformation Technology on Company Sustainability Areas

The impact of new digital technologies creates challenges for the digital transformation process in company sustainability areas. The purpose of this study was to determine the degree of contribution of digital-transformation-enabling technologies to company sustainability areas of three pulp and paper manufacturing companies in Brazil and relate it to the UN Sustainable Development Goals (SDGs). Through a systematic literature review based on the PRISMA method, we sought to assess the key concepts of sustainability and the implementation of digital transformation (DT) through its enabling digital technologies. A field study was conducted in three Brazilian pulp and paper companies to assess the degree of contribution. They are leading companies in the paper and cellulose industry in Brazil. The results obtained indicate that the companies in this sample are still in a growth process regarding the use of digital technologies in their sustainability areas. Only one digital technology, cloud computing, appears relevant in one of the companies studied, which differs from the theoretical framework presented by the literature. To achieve the SDGs goals, countries, especially emerging ones, need to develop their technologies and their business and improve the results that relate to sustainability. The research method applied in this study can be replicated to other companies where the impact of digital transformation technologies on company sustainability is critical.

The ANALISIS BEBAN KERJA OPERATOR PAPER MESIN #6 PT. INDAH KIAT PULP AND PAPER TBK MENGGUNAKAN METODE CARDIOVASCULAR LOAD (CVL) DAN SUBJECTIVE WORKLOAD ASSESSMENT TECHNIQUE ( SWAT )

Indah Kiat Pulp and Paper Tbk merupakan perusahaan industri manufaktur yang bergerak dibidang pengolahan bubur kertas, salah satu mesin kertas terbesar di Perawang adalah Paper mesin #6. Paper mesin #6 beroperasi secara kontinyu 24 jam dan untuk mendukung proses produksi tersebut jam kerja karyawan dibagi menjadi 3 shift kerja. Permasalahan yang terjadi pada paper mesin ini adalah tingginya angka kecelakaan kerja dikarenakan tingginya beban kerja yang dirasakan oleh operator sehingga menyebabkan operator kelelahan baik fisik maupun mental. Penelitian dilakukan pada operator stasiun produksi Wet End, Dry End, Chemical, Winder dan Thimons yaitu dilakukan pengukuran beban kerja fisik dengan menggunakan metode Cardiovascular Load (CVL) dan pengukuran beban kerja mental dengan metode Subjective Workload Assessment Technique (SWAT). Hasil perhitungan metode CVL bahwa beban kerja fisik yang paling besar pada shift 3 grup B terjadi pada operator Thimons 1 memiliki nilai % CVL sebesar 46,62 % dengan rekomendasi diperlukan perbaikan dan operator Wet End 3 dengan nilai % CVL sebesar 44,74 % dengan keterangan diperlukan perbaikan. Berdasarkan hasil CVL, sebanyak 12 karyawan mengalami beban kerja fisik. Berbeda dengan kepala shift dan operator Dekstop Control System (DCS), beban kerja yang dirasakan cenderung lebih ke beban mental. Penelitian pada kepala shift dan operator DCS menggunakan metode, metode SWAT digunakan untuk mengukur beban kerja mental. Penelitian dilakukan dengan cara pengamatan dan wawancara secara langsung, selanjutnya kepala shift dan operator DCS diminta untuk mengurutkan 27 lembar kartu SWAT yang terdiri dari Time Load(T), Mental Effort Load(E) dan Psycological Stress Load (S). hasil pengurutan kartu SWAT diolah dengan menggunakan aplikasi DosBox 0.74, setelah itu dilakukan pengkonversian nilai dari Time, Effort dan Stress (T.E.S). Berdasarkan perhitungan beban kerja mental kepala shift, faktor yang paling berpengaruh adalah faktor Time dengan nilai 60,44% diikuti faktor Effort dan Stress dengan nilai 29,64% dan 9,92%. Hal serupa dengan operator DCS, faktor yang paling berpengaruh adalah faktor Time dengan nilai 68,57% diikuti faktor Effort dan Stress dengan nilai 23,29% dan 8,13%. Beban waktu menjadi faktor utama yang dirasakan oleh karyawan karena tuntutan pekerjaan yang mengharuskan karyawan harus cepat dalam melakukan setiap aktivitas.
