Hi, Plastic bags are made primarily of hydrocarbons.
1. Dissolved in a solvent, they might make a useful diesel fuel. 2. Bundled and compressed the bags might be burned instead of coal. 3. Added to a blast furnace, they could replace, or augment coal. 4. Subjected to pyrolysis, they might yield lighter hydrocarbons that could be used in the chemical industry. All of these options are better than them swimming around in the ocean. Regards, Robin van Spaandonk local asymmetry = temporary success
