European levy on plastic waste per January 2021

The European Counsel agreed to make plastic waste taxable.
Per January 1st, 2021, the levy on plastic waste will be € 0,80 per kilogram.

From the EU note:

As a first step, a new own resource will be introduced and apply as of 1 January 2021 composed of a share of revenues from a national contribution calculated on the weight of non- recycled plastic packaging waste with a call rate of EUR 0.80 per kilogram with a mechanism to avoid excessively regressive impact on national contributions.

In several EU countries plastic waste is “taxed” in a certain way.

Will this be additional? And will it be charged for every kilogram of plastic?
