C. The waste plastics are petroleum derived and therefore, provide a hydrocarbon source that can be used for chemical feedstocks. The feedstocks are mixed and processed simultaneously with the dual objective of liquefying the solid waste and upgrading the heavy residue from either the liquefied solid wastes or petroleum oil to the premium fuel oils boiling lower than 500°C. 

Landfill gas is produced as a result of organic wastes decomposing in landfill sites. It can be recovered at an inexpensive cost of for direct use as a boiler fuel, converted into electricity with a microturbine or upgraded to a higher value fuel gas. This is a very effective mitigation technology since methane is 21 times as powerful as carbon dioxide as a greenhouse gas. 

The different pyrolysis and gasification technologies, selected in relation to the waste input, generate different kinds of products that will have to be upgraded into substitution fuels. The solid fuel could be upgraded by mechanical separation of metals and minerals in order to produce a cheap feedstock to a classical gasifier. Moreover, selected additions during pyrolysis could entrap pollutants such as chlorine and heavy metals [2,3,63,64].
