Nice sentiment ..but impossible to do and make any significant impact....take the lowly straw and the plastic wrapping stuff from the grocery store.. they're thrown in the plastic bag under the kitchen sink, then taken to the even heavier/stronger plastic bag that holds the weekly garbage then taken to the curb. Then off to landfill.
Those two layers of plastic holding the single use plastic waste will never degrade so the contents of the bags is a non-issue. Inventing something biodegradable that is capable of handling the trash from a house....not in the foreseeable future and cost prohibitive.
Controlling waste disposal as a whole is the answer...incinerators like Singapore uses have solved the problem. Turn pollution into a resource.
Making straws illegal is a stupid gesture; more 'virtue singling' from Climate Barbie and the environmentalists.
Watch the video...I think you'll be amazed.
