“…As per TGA analysis, the optimum temperature for producing maximum oil was in the range of 300-500°C. Above 500°C the operation reduces liquid and char production and provides an increased amount of gas, several studies have explored the same effect (Madhu et al, 2018;Mankhand et al, 2012). This reduced liquid and char at higher temperatures and could be the reason of the secondary reaction for the liquid fraction of the volatiles and further decomposition of the char particles.…”

“…The technique is well known to produce fuel oil from biomass. Additionally, the char and gas produced as a by-product can be used in a variety of ways (Madhu et al, 2018). Furthermore, other wastes can also be pyrolysed such as e-waste plastic which is present 50-60 % in printed circuit boards (PCB).…”

“…Additionally, it contains a large amount of volatile matter and lower O/C (Madhu et al, 2018); Kim et al, 2013) which gives an expectation of high bio-oil yield with improved quality (W. J. Madhu et al, 2018). Therefore, there were two wastes which were combined to produce energy in the form of fuel oil and gas.…”

With advancing technology, PCB (Printed circuit board), one of the most important components of e-waste, has become a source of pollution due to an ineffective waste management system. This problem can be solved by converting PCB waste into a valuable product which will emerge to maximize the renewable energy supplies. In this aspect, co-pyrolysis is advantageous in both simple and successful in producing high-quality pyrolysis oil. In this paper, cotton stalk (CS) as biomass was used for co-pyrolysis with PCB. Slow pyrolysis of PCB, CS, and co-pyrolysis of PCB:CS (1:1) have been carried out for temperatures up to 500 \(℃\) in a fixed-bed reactor. The products of pyrolysis: oil was analysed by GC-MS and FTIR and gas had been analysed by GC. The results indicate that there is an increase in oil yield from 19.6% to 27.5 % by weight and phenol and phenolic compounds in oil of co-pyrolysis from 60.94–76.82% than literature available. As per authors knowledge co-pyrolysis of PCB:CS has been attempted first time and the products characterisation were found completely different than any other biomass co-pyrolysis with PCB.

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.
