“…GC-MS characterization of the DIR derived organic phase bio-oil indicates the presence of polycyclic aromatic hydrocarbons (PAHs) in this phase of bio-oil, which were probably originated from paper additives, coatings, ink particles and/or other chemicals used during deinking processes. 23 Adhesive properties of bio-oils derived from various waste streams A small amount (70 mg) of the crude organic phase bio-oil derived from spruce wood chips, waste paper and DIR was used directly as an adhesive for bonding of Al plates (surface sizes: 50 mm × 50 mm) by curing in oven at various temperatures and time. From the appearances of the Al -bio-oil -Al interfaces post tensile strength tests for specimens oven cured by the organic phases of bio-oils ( Figure S7 to S9), it can be seen that all the bio-oil adhesives were polymerized during curing.…”

Making innovative use of low-value and underutilized biorenewable waste streams, and the unavoidable losses resulted from industrial practices, is crucial for transitioning from a petro-to a bio-based economy in the 21 st century. This study provides a holistic and comprehensive overview of the adhesive properties of bio-oils generated from microwave-assisted lowtemperature (< 200 o C) pyrolysis of three biorenewable wastes: spruce wood chips, waste paper and paper deinking residue (DIR). The spruce wood chips and waste paper derived bio-oil could bond two Al plates with high tensile strengths generally. Highest tensile strengths around 2520 N were reached with the spruce wood chips derived bio-oil. The ATR-IR and solid-state CP/MAS 2 13 C NMR characterization of the bio-oil polymer scrapings reveal that the bio-oil possibly undergoes homo-and/or cross-coupling reactions during curing. A model compound study using 5-hydroxymethylfurfural (HMF), levoglucosan and catechol was conducted to study the role of different categories of compounds within bio-oil in terms of bonding. The adhesion properties of both single model compound, mixtures of each two and/or three of the model compounds with various molar ratios were explored. The results indicate that the presence of (hetero-) aromatic and furan compounds is crucial towards good adhesion.

“…menghasilkan produk pirolitik dari deinking sludge cake dalam reaktor tubular statis terdiri dari gas (29,78%), tar (24,41%) dan residu padat (45,81%). Zat volatil hasil pirolisis deinking sludge cake sebagian besar berupa hidrokarbon aromatik, yaitu stirena, toluena dan benzena dan beberapa asam (Lou et al, 2012). Namazi, dkk.…”

ABSTRAKSludge cake hasil pengolahan air limbah dan pulp reject dari pabrik pulp kraft merupakan sumber energi terbarukan. Penelitian ini mengevaluasi pengaruh suhu terhadap pirolisis untuk mengkonversi sludge cake dan pulp reject menjadi produk tar dan arang. Sludge cake memiliki komposisi (adb): air lembab 9,08%, zat terbang 57,53%, karbon tetap 8,72% dan abu 24,67% dengan nilai kalor 2931 kal/g, sedangkan pulp reject mengandung air lembab 9,42%, zat terbang 68,16%, karbon tetap 17,00% dan abu 5,42% dengan nilai kalor 3656 kal/g. Kandungan zat terbang yang tinggi menjadikan sludge cake dan pulp reject berpotensi menghasilkan tar. Puncak pirolisis tercapai pada 349 o C untuk sludge cake dan 300 o C untuk pulp reject. Konversi mencapai 30% pada 300 o C dan 80-90% pada 400 o C, dengan hasil tar mencapai 39% untuk sludge cake dan 47% untuk pulp reject. Pada suhu >400 o C tar yang terbentuk terdekomposisi menjadi gas pirolisis. Perbedaan komposisi bahan dan kenaikan suhu pirolisis mempengaruhi komposisi tar yang dihasilkan. Hasil arang pirolisis 300-500 o C tidak berbeda jauh, baik pada sludge cake maupun pulp reject. Semua komponen zat terbang pada sludge cake maupun pulp reject habis tergedradasi dalam waktu tinggal 60 menit.

“…Bioenergy, derived from biomass [1,2], municipal organic solid waste [3], livestock manure [4], and other biological materials [5][6][7], has been seen increasingly as a renewable and clean energy source. Among all utilization methods in bioenergy research (such as direct combustion, thermo-chemical conversation and biological conversion technologies) fast pyrolysis-a rapid decomposition of organic materials in the absence of oxygen-has many advantages.…”
