[ 15 ] [ 16 ] In some areas there have been significant efforts to reduce the prominence of free range plastic pollution, through reducing plastic ...
Radicals formed on the polymer backbone by either hydrogen abstraction side-group elimination can cause the chain to break by beta scission. As a result the molecular weight decreases rapidly. As new free radicals with high reactivity are formed, monomers cannot be a product of this reaction, also intermolecular chain transfer and disproportion ...

It is a disposal method used globally, but often used in low and middle-income countries that lack adequate waste disposal infrastructure. Numerous governments and institutions have identified the open burning of waste as a major contributor to greenhouse gas emissions. It also ...

The private burning of dry cellulosic/paper products is generally clean-burning, producing no visible smoke, but plastics in the household waste can cause private burning to create a public nuisance, generating acrid odors and fumes that make eyes burn and water. A two-layered design enables secondary combustion, reducing smoke. [10]
