“…It can be seen from Table that polyester plastics have a limited role in increasing the calorific value of bio-oil. But Simanungkalit et al showed that polyester plastics increased the heat value of bio-oil by 37%, about four times as much as polyolefin plastics. The difference may be related to the type of biomass and reactor.…”

Pyrolysis is one of the substantial thermal conversion technologies for high-value reutilization of biomass and organic solid waste (OSW). Adding some typical OSWs to biomass pyrolysis can achieve directional regulation of target products that are considered potential alternatives to fossil energy. Understanding copyrolysis behaviors is vital for the optimizing pyrolysis process to minimize environmental pollution and efficiently utilize biomass and OSW. However, there is no overall review on the copyrolysis of biomass and various OSWs. This paper reviews and discusses recent advances in the copyrolysis mechanism, thermal−chemical processes of some typical OSWs and biomass, and effects of chemical compositions of raw materials and pyrolysis parameters on thermal−chemical conversion behaviors, synergistic effect, and copyrolysis product characteristics. Recent reports show that the synergistic effect in copyrolysis effectively improves the quality of bio-oil and biochar. Moreover, adding OSW to biomass pyrolysis can promote the secondary reaction of pyrolysis intermediates. The reaction mechanism and relative numerical simulation work of copyrolysis are summarized. Finally, the current challenges to energy-and environment-oriented conversion of biomass and OSW are discussed, and perspectives for further developing the copyrolysis process are highlighted. This paper provides valuable information for optimizing sustainable copyrolysis processes of OSW and biomass and improving the efficiency and selectivity of recycled OSW.

“…Produk yang diperoleh dibandingkan dengan produk co-pyrolysis CKS dengan plastik kemasan jenis PE. Berbeda dengan publikasi sebelumnya (Simanungkalit et al 2018), investigasi terhadap efek sinergis dilakukan dalam penelitian ini. Proses pirolisis dilakukan dalam reaktor unggun tetap dengan bahan baku biomassa dan limbah plastik kemasan serta campurannya.…”

“…Setelah analisis termogravimetri selesai dilakukan, maka dilanjutkan dengan proses pirolisis dalam reaktor unggun tetap yang berdiameter 33 mm dengan panjang 560 mm dan terbuat dari bahan besi tahan karat kelas 304. Reaktor dipanaskan menggunakan pemanas listrik eksternal yang dilengkapi dengan kontrol dan sensor temperatur (Gambar 1) (Simanungkalit et al 2018). Sampel berbentuk pelet dengan kisaran berat 20 g dimasukkan ke dalam reaktor, kemudian dipanaskan dari temperatur ruang hingga 500 °C dalam atmosfer N 2 dengan laju pemanasan 10 °C/menit.…”

Sementara itu, degradasi termal bahan baku plastik mulai terjadi pada temperatur ≥380 °C untuk PET (Gambar 2.b) dan pada temperatur ≥400 °C untuk PE (Gambar 2.c) (Simanungkalit et al 2018). Kemudian pengurangan massa kedua bahan baku plastik terjadi dengan drastis hingga mencapai temperatur 500 °C dan cenderung konstan setelah itu.…”

In the present study, the co-pyrolysis of biomass waste, i.e. palm kernel shells (PKS) and industrial packaging plastic waste, namely polyethylene terephthalate (PET) and polyethylene (PE) were conducted. Prior to the pyrolysis, the raw materials were analyzed by thermogravimetric and elemental procedures. The pyrolysis was conducted in a fixed bed reactor which was heated from room temperature to 500 °C in an N 2 atmosphere with a heating rate of 10 °C/min. The raw materials were weighted and mixed together manually with variations of weight composition ratios between biomass and plastic, i.e. 100% biomass (100/0); 90% biomass and 10% plastic (90/10); 70% biomass and 30% plastic (70/30); 50% biomass and 50% plastic (50/50); and 100% plastic (0/100). Then, they were put under pressure to obtain a pellet. The synergistic effect of biomass and plastic was investigated to see the difference between the pyrolysis products yields in theory and experiment. The bio-oil products were characterized by several methods and showed the potential to be used as a fuel. The optimum condition was obtained from 50/50 weight composition ratio. It was gained 30% improvement of the higher heating value of bio-oil, and the percentage area of hydrocarbon was contained in bio-oil increased from 4.68% to 53.40%.
