I would go beyond that. On top of taxing plastic, we should also create a 'new' plastic quota. Petro-chemical industry makes profit only on new plastic not recycled plastic. They will forever fight this transition away from plastic. If you introduze a plastic 'from oil' quota, the Nestlé's and Unilever's of the world would have to bid for a share of new plastic in a "new plastic market", making plastic from oil more expensive. This would incentivize manufacturers to either create plastic return deposit schemes, or to recycle more plastic, or just straight move to glass/aluminium/paper. Edit: the point of this is that it would desincentivize manufacturers away from plastic while increasing the "per tonne" profit of petro-chemicals (who would be manufacturing a lot less).
