Abstract
Pyrolosis= thermo-chemcial proccess with the purpose of disposal of plastic waste
Things that affect the product
Type of plastic
method: slow pyrolysis, fast pyrolysis and flash pyrolysis
type of reactor
particle size of the plastic
Can help allevate pollution in the environment and help with generating energy
gas, liquid oil, and wax are some of the products of pyrolysis
about 5% increase of plastic production each year
Plastic is everywhere
2 catergories of plastic waste: (1) pre-consumer or industrial plastic wastes and (2) post-consumer or municipal plastic wastes
Introduction
Plastic pollution
Plastic is used in almost everything in our daily lives
current municipal facilities deal with about 10-13% of plastic world wide
Many types of plastic makes it harder to recycle
does not biodegrade like organic materials
endangers many organisms in the different environments
Possible disposal
recycling
hard to completly seperate different types of plastic
need to mix virgin pellets into the mixure still
Plastic degrades with heat
incineration
releases harmful gases into the air: CO, CO2, NH3, N2O, NOx
landfill
