The developing of
alternative fuel has been investigated in the past decade due to the fast
depletion of fossil fuels. The aim of these technologies is to recover energyfrom waste materials, including materials that are not biodegradable, such as
biomass, municipal solid wastes, agricultural wastes and as high energy density
materials such as rubber and plastics.
Plastic are non-degradable
polymers which contain carbon, hydrogen and others elements (chlorine,
nitrogen, etc.). Due to its non biodegradable nature, this compound contributes
significantly to the problem of waste management.
There are different
environmentally friendly ways of recycling plastic waste compared with
incineration and disposal in landfills. ASTM D7209-06 indicates that theplastics can be recycled using four types of methods according to the finalresult, one of them being the chemical recycling. In this method, chemical
degradation leads to production of liquid fuels and chemicals with high added
value from waste plastic fragments or segregated. One of this method is
pyrolysis.
