Due to the nondegradability of PP plastics, their heavy accumulation in the environment is causing hostile effects on ecosystem including soil erosion . Conventional routes to recycle PP plastics such as mechanical recycling, land filling, incineration, and chemical recycling  suffer from many hostile impacts such as landfill waste, clogged waterways, occupational health hazards, energy consumption, animal death, water contamination, foreign oil dependency, toxic pollution, soil degradation, costly 156production/recycling of plastics, and landscape litter. Additionally, these techniques have following limitations.
No valuable by products are formed; rather one form of plastic is converted to another, which has no commercial value.
Requiring high energy and manual efforts.
Heavy pollutants are generated during the process.
