E.g. the chemical companies are usually only considered responsible for the emissions of their plants, while the bulk of emissions happens on landfills or in incinerators. Waste-to-Energy-Incinerators on the other hand are in many places even considered &amp;quot;green&amp;quot; energy, because they say we&amp;#x27;re only using waste that&amp;#x27;s already there.</text><parent_chain><item><author>pizza234</author><text>Something I don&amp;#x27;t fully understand is why single-use plastics are still in use.
