howdy from Texas k4r1nn! wow there are literally mountains of waste there, amazing, I suppose the workers there have to wear masks too?
Anyway this is a great post and very educational with fine photos, I hope they keep improving their waste management system there, I know it's a very difficult problem!
Workers are provided all the safety equipment yes although I saw a few of them that chose not to wear masks. I asked the tour guide why they are not and she said it was their own choice. I would make that mandatory. Thanks for stopping by and all the best @janton
howdy again k4r1nn! oh my, I can't imagine not wearing a mask there! thanks so much for the explanation.
