First, I can't say that a homeowner burning plastics is a good idea for the environment. Nor for the normal
wood stove either.
A tale.... Years ago a friend on mine decided to heat his shack by burning plastic. Not that I support his decision, but I can understand it. He was broke and had no means of
cutting firewood that year. He was burning twigs and whatever small branches he could bust up. As the winter temps plunged down into single digits he started burning plastic. Plastic pallet wrap, and when that ran out, plastic bottles. He saved himself from freezing that winter, but he did cause some damage to his
wood stove and burnt a hole through the base of his stove pipe. Apparently plastic burns a lot hotter than
wood. Lucky for him, his
wood stove was one of those wood/coal burners so it survived to high temperatures. End of tale---plastic will burn and produce intense heat. But at what cost to the environment? I don't know.
I am aware that the State of Hawaii allows one of the electricity generating companies here to burn plastic. But I don't know what the furnace requirements are, nor what the state of pollutants are.
I would think there has been lab work done on this topic but I don't know where to look for the results. Probably posted somewhere on the web on a professional site.
