I agree with you that the manufacturers should bear the cost of recycling their own packaging. We understand from our family in Germany that ALDI and LIDL have already made huge progress in making their packaging recyclable. Even in the United Kingdom, IKEA’s packaging is mostly recyclable.
In areas along the Rhine, you have a country on one bank conscientiously recycling their waste for decades whilst the country on the other bank has a problem with yellow bags. The new reforms are long overdue in France because even the current rules are flouted.
As an example, we recall the time when a half-eaten pizza was thrown into the communal recycling bin in its original cardboard box, in our flats. At that time every recycling bin had a list of permitted contents posted in French. The very next day the contents list was posted in English so the concierge obviously suspected us. We complained because my other half is German and knows all there is to know about proper recycling.
And on the same subject, we cannot understand why so many healthy vegetables are sold in steel cans in France. Admittedly steel (and the tin coating) are very suited to recycling but at what cost to the environment? All of these tins are easy to extract from the rubbish because they are magnetic but they have to be melted down and this uses an enormous amount of energy.
