> For example Germany, while the country is famous for the whole splitting the garbage, I am still waiting after 20 years to see the kitchen oil recycling recipients as we have in Portugal.

Because German environmental policy is about virtue signalling to keep the plebs busy, not solving environmental problems. Nuclear power plants replaced by coal and natural gas, obsession with recycling but nothing done about disposable packaging, car regulations and city design dictated for decades by the car manufacturing lobby, combustion engine limits/bans only when said manufacturers thought they could get on the Tesla gravy train and subsequently rolled back when reality became apparent, it just goes on.
