Lets not kid ourselves, many "civilized" countries are way lacking when it comes to solving waste problems.How do civilized countries process wastes? Do they have dump sites?
Just a few things to know, even if the people separate their waste, they still need places to take each separated group, and in many countries like USA Canada and especially Australia, there is a fraud process that takes place. Biodegradables are dumped, they even lack much composting procedures. What is plastic for example is gathered in places but only a few number is recycled, most of them used to be taken to China, now after China stopped taking trash since the beginning of this year, they have been sending their trash to Malaysia and Philippine, illegally. In Malaysia for example there are sites where most trash is Australian. In Philppine recently, the president sent back Canada's trash and told them to eat it if they want. China used to do most of the recycling and use the poor-quality recycled products for cheap toys. In Europe its better especially Germany and the scandinavian countries. Even countries like Italy have a progressive waste disposal policy and we should look at it because we have similar lansdcape and climate. But anyway a complete solution is not available. You can manage it as much as you can. but you will have to dump big parts of it. Also people think only dumping plastic and the likes is harmful but environmentalists oppose this saying that dumping food causes heavy methane emissions, so while the food is gone as mass, its transferred into something dangerous.
All in all, even if we try to take it step by step in lebanon it is still problematic. With our dense population, huge number of refugees ( whom for example cannot be forced to comply with separation techniques; and Northern lebanon and cities like zgharta are big proof for that) and lack of planning and stability, its almost an impossible mission to even begin improving.
The thing that can help us most in my opinion is looking at this trash crisis including Syria. First Syria must help because there is human transfer from one place to another so they must take the burden in helping in any way possible. This is the most important step in fixing the imbalance in demographics. Trying to squeeze everything in this tiny country just because we refuse to look at our land and syrian land as one land naturally is going to hurt us on and on. We should start looking at the bigger picture and coordinating.
