“…e radical secondary reactions are the main reason for the synergetic effect in this condition [36]. Furthermore, the presence of plastics on the reaction serves as a hydrogenation medium for lignocellulosic material, potentially reducing the polymerization and cross-linking activities ensuing major weight loss [37]. At 80% blend also the synergistic effects are identified for oil yield, but the increment was only 3.46%.…”

Two totally waste products, agricultural residues and mixed plastic wastes collected from domestic and industrial sectors, are used in this study for the recovery of energy rich biofuel and value-added chemicals. The copyrolysis experiments using fixed bed reactor are conducted in order to analyse the synergetic effects. The experimental works are carried out with different proportion of mixed plastics blended with agricultural residues. The reaction temperature and biomass-to-waste plastics ratio on product distributions are studied and addressed. The thermogravimetric analysis conducted at different temperatures clearly distinguished the pyrolysis behaviours of biomass and plastics. The positive synergistic effects defined as higher yield of volatiles compared to predicted yield for bio-oil were identified at particular mixing ratio. Both biomass wastes and plastic wastes show optimal performance of 60.42 wt% oil yield at 60% addition of waste plastics. The oil products obtained under favourable conditions have a higher heating value compared to the oil obtained from biomass pyrolysis. The GC-MS study confirmed that the interaction between biomass and plastics during copyrolysis resulted in decreased oxygenated contents in the oil products.

In this study, the investigation on effect of plastic during co-pyrolysis with biomass has been carried out in a fixed reactor. Pyrolysis of neem wood bark (NB), low density polyethylene (LDPE) and their blends at different ratios is performed in order to evaluate the product distribution. The effects of reaction temperature, NB-to-LDPE blend ratio on product distribution and chemical compositions of bio-oil are examined. The co-pyrolysis of NB and LDPE increased the yield and quality of the bio-oil. The experiments are conducted under different LDPE addition percentage such as 20%, 40%, 50%, 60% and 80%. Under the optimum experimental condition of 60% addition of LDPE and temperature of 450°C, the maximum yield of bio-oil (64.8 wt%) and hydrocarbon (75.2%) are achieved with the lowest yield of oxygenated compounds. The calorific value of the co-pyrolytic oil is found to be higher than that of NB pyrolytic oil. The relation between NB and LDPE during co-pyrolysis has been validated by GC–MS analysis, which shows in decrease of oxygenated compounds.
