Poem on plastic waste management for plastic free india
Answers
Answer:
evidence to the debates surrounding plastic waste management options and their effects on the environment.
A recurring theme in the debates around plastic waste management system is the extent to that whether the plastic waste disposal options give genuine benefits to the environment. Often, criticizers of the strategy drive towards larger plastic recycling assert that the act of recycling could be in fact has less or no benefit to the environment, consuming extra energy in the collection and transportation of plastic waste to the recycling facilities than is saved by the procedure of recycling.
In order to notify this debate in details, this dissertation commissioned a key international LCAs studies. By reviewing considerable international studies, and employing rigorous criteria to filter out those studies that have less robust methodology and assumptions, after the number of studies screened 11 state of the art LCAs were selected for methodical study, including disparate scenarios. The result is more objective oriented analysis of the environmental encounters of different waste management methods for Plastics waste than one single study can deliver.
Through the use of past LCAs, it investigates both plastic waste disposal options and environmental effect of the activities of plastic waste management by using meta and statistical analytical methods. Research methodology also considered, setting up a framework to review and selection restricting criteria for LCA studies. In so doing it provides the waste management methods performances with regards to environmental indicators. Persuading plastic methods have been chosen to comparing options :Landfilling, recycling, incineration and pyrolysis performances with regards to perusing environmental impact indicators: climate change, depletion of natural resources, energy demands and water consumption.
This dissertation focuses on recycling, incineration, landfilling and pyrolysis that are plastic waste disposal methods and their performance concerning climate change, depletion of natural resources, energy demand, and water consumption that are environmental impacts indicators. By reviewing past LCAs, it investigates plastic waste management options and environmental effect of the activities involved. For selection of LCA studies restricting selection criteria are developed. Meta analytical methods were adapted to synthesize and codify the findings of LCAs. Codified data were statistically analysed to calculate mean size effect. It provides the best, intermediately and the worst option concerning environmental performances of plastic waste management methods.
The results are clear that all of the studies prop the following conclusions:. after comparison between of recycling, land filling, incineration and pyrolysis of waste plastic, Recycling appears to be a preferable management option over alternatives. Whereas, pyrolysis method emerged as a promising option for plastic waste disposal.
