As I said in my last post, NOTHING gets wasted here. It's all reused, recycled or repaired.
Cows roam the streets. Naturally they leave something behind wherever go. No problem---someone else comes along and collects it to make into cooking fuel. It can be shaped into 'patties' like the ones above, then stuck onto a wall or hard surface to dry.

Or, it can be shaped around a stick and left to dry. These dried cow dung sticks are used like wood in a cooking fire.
Below, the dung sticks are drying against a village home. The flowering plant on the roof is a type of squash. Banana tree leaves can be seen in the back. I liked the colors, textures and 'rhythm' of this scene.
It is certainly resourceful use of cow dung, but is not so clearly eco-friendly. The dung cakes are a dirty fuel, and make a big contribution to the Asian brown cloud:

A much better solution is to use the dung for biogas -- but there aren't many of them in BD yet.
