{"title":"Co-Pyrolysis of Olive Pomace with Plastic Wastes and Characterization of Pyrolysis Products","authors":"Merve Sogancioglu, Esra Yel, Ferda Tartar, Nihan Canan Iskender","volume":112,"journal":"International Journal of Environmental and Ecological Engineering","pagesStart":480,"pagesEnd":484,"ISSN":"1307-6892","URL":"https:\/\/publications.waset.org\/pdf\/10004538","abstract":"Waste polyethylene (PE) is classified as waste low
\r\ndensity polyethylene (LDPE) and waste high density polyethylene
\r\n(HDPE) according to their densities. Pyrolysis of plastic waste may
\r\nhave an important role in dealing with the enormous amounts of
\r\nplastic waste produced all over the world, by decreasing their
\r\nnegative impact on the environment. This waste may be converted
\r\ninto economically valuable hydrocarbons, which can be used both as
\r\nfuels and as feed stock in the petrochemical industry. End product
\r\nyields and properties depend on the plastic waste composition.
\r\nPyrolytic biochar is one of the most important products of waste
\r\nplastics pyrolysis. In this study, HDPE and LDPE plastic wastes were
\r\nco-pyrolyzed together with waste olive pomace. Pyrolysis runs were
\r\nperformed at temperature 700°C with heating rates of 5°C\/min.
\r\nHigher pyrolysis oil and gas yields were observed by the using waste
\r\nolive pomace. The biochar yields of HDPE- olive pomace and LDPEolive
\r\npomace were 6.37% and 7.26% respectively for 50% olive
\r\npomace doses. The calorific value of HDPE-olive pomace and
\r\nLDPE-olive pomace of pyrolysis oil were 8350 and 8495 kCal.","references":"[1] McKendry P. Energy production from biomass (part 1): overview of\r\nbiomass.
