Not to go way off-topic, but I'm curious as to how much the deposit is over there. If there aren't that many bottles and cans littering the road, I have to assume it's more than the euro equivalent of $0.05.
I converted from my local currency and this fee would be 0.07 EUR in my country, but I am not sure how much this fee is in other EU countries. Also, the rule was that you can return such packaging only in the country where you bought it, so tourists leave behind a lot of plastic packaging that means nothing to locals. However, in my country, all waste has been sorted for years, so we specifically collect plastic, paper, glass, biowaste and other mixed waste - which results in a much cleaner country than 10+ years ago.
And that's great the EU has adopted the "bottle bill" model, because not only does it help the environment, but it actually redistributes wealth to a small extent. As I said, many homeless folks (and people with homes as well) can make enough to survive in the US states that have bottle bills. Unfortunately, it's only a small number of them.
You have to take into account that each member of the EU can have its own specific laws, and given the language barriers, I cannot say what is happening in Romania or Spain in this regard - but I think it is similar with all federal states in the US, except that you perfectly understand each other because you speak the same language.
There are many stories in my country about how people managed to educate their children by collecting such packaging, and how it is still an additional source of income for them today. I personally know a man who has developed a unique method in this matter, which is that he is well informed about when a celebration is happening somewhere (birthday, wedding) and offers the service of collecting all plastic, aluminum and glass packaging, and rich people usually agree because they don't need that money anyway.
Oh man....whenever anyone mentions faucets my mind goes back to when I first really got into bitcoin. There were tons of them, and that's how I acquired my first few satoshis. I'd still consider what you get from them "free", even if you're spending a few seconds going through the motions of the captcha, ads, and whatever else is required.
That's how I earned my first Bitcoin, but it wasn't that hard considering the price was around $200 and the fact that compared to today it was very easy to collect satoshis through faucets. A good faucet rotator and a few referrals could generate up to 500 000 satoshis in one day. Of course, from the perspective of that time, it was very little in fiat value, but in later years we all know that this value increased to unprecedented values.
