“…The reason may be due to the higher volatile content of plastic waste samples. Islam et al (2010) reported that the higher volatile matter of feedstock with low ash content was a potential source for higher fuel oil yield. In the present study, the residence time observed for tested plastic waste samples ranged from 39 to 58 min.…”

Waste plastics are a significant contributor to municipal and industrial wastes. Today, environmental pollution caused by waste plastics is a worldwide serious problem due to their continuous accumulation in the environment and inability to biodegrade for a long period. As a result, it is critical to find a safe way to dispose of waste plastics. Pyrolysis is one of the most effective methods for recovering useful products from waste plastics. The pyrolysis of waste polyethylene (PE) carry bags in a batch-type reactor is studied and discussed in this paper. Generally, the pyrolytic conversion of feedstocks produces solid, liquid, and gaseous products. Optimization experiments were carried out in a batch-type pyrolysis system at 400, 450, 500, and 550 oC to recover maximum fuel oil from plastic wastes. At 500 °C, the maximum fuel oil yielded as 59.3 percent in 42 minutes from waste PE carry bags. Whereas, the char and gas yields ranged from 6.6 and 34.1%, respectively. The calorific value of fuel oil was 40.8 MJ/kg. The presence of alkanes, alkenes, and alkynes functional groups in fuel oil was revealed by FT-IR analysis. These findings suggest that fuel oil derived from waste PE bags can be used as an alternative fuel.

“…Activated carbon is a carbon-based adsorption material composed of microcrystalline structure and amorphous carbon, with well-developed pore structure and generally high speci c surface area and pore volume [9] . Sugarcane bagasse is the main byproduct in the sugar production process and is a type of agricultural and forestry biomass waste [10] , which is usually treated through boiler combustion or direct treatment, causing environmental pollution and resource waste [11,12] .…”

The sugarcane based activated carbon was prepared by one-step method using sugarcane bagasse as raw material and H3PO4 as activator, meanwhile in order to get the better preparation condition of the materials the dose of phosphoric acid addition, material liquid ratio, activation temperature, and activation time on the adsorption performance of activated carbon were discussed. This study investigated the effects of different preparation conditions on the adsorption and desorption performance of activated carbon through characterization such as BET, FT-IR, XRD, dynamic adsorption, and static adsorption, which has shown that when the phosphoric acid content was 30%, the solid-liquid ratio was 1:2, the activation temperature was 400 ℃, and the activation time was 30 minutes by one-step method, the carbon content reached 55.73%, but its specific surface area can reach 1037.7m2 /g, the saturated adsorption capacity can reach 487.3mg/g, and the adsorption capacity was still above 80% after three regenerated, and the adsorption and desorption performance was the best.

“…The same applies for the Arundo, which has been extensively studied with respect to bio-char production. − Data from fast pyrolysis of Arundo are very scarce that is done mainly with small batch-type reactor systems, − and reported organic liquid yields from thermal pyrolysis have been low (20 wt %) . On the other hand, data from the fast pyrolysis of bagasse and eucalyptus are more abundant, and typical organic liquid yields from these feedstocks are higher (28–50 wt %). − Eucalyptus typically produces FPBO with quality comparable to the other wood feedstock, such as commonly used pine residues. , On the other hand, FPBO quality from the bagasse has been reported to vary significantly, which can be explained by high variability in bagasse feedstock quality. , …”

Fast pyrolysis of giant reed Arundo ( Arundo donax ), fiber sorghum ( Sorghum bicolor L. Moench), eucalyptus ( Eucalyptus spp.), and sugarcane bagasse ( Saccharum officinarum ) was studied in bench-scale bubbling fluidized bed reactor. Product yields were determined, and detailed physicochemical characterization for produced fast pyrolysis bio-oils (FPBOs) was carried out. The highest organic liquid yield (dry basis) was observed with sugarcane bagasse (59–62 wt %), followed by eucalyptus (49–53 wt %), giant reed Arundo (39 wt %), and fiber sorghum (34–42 wt %). After the pyrolysis experiments, produced FPBOs were gasified in an oxygen-blown autothermal catalytic reforming system for the produced synthesis gas. The gasifier consists of a partial oxidation zone where the FPBO is gasified, and the raw syngas is then reformed over a fixed bed steam-reforming catalyst in the reforming zone. The gas production (∼1.7 Nm 3 /kg FPBO) and composition (H 2 ∼ 50 vol %, CO 20–25 vol %, and CO 2 25–30 vol %) were similar for all FPBOs tested. These results show that the combination of fast pyrolysis with subsequent gasification provides a technically feasible and feedstock flexible solution for the production of synthesis gas.
