Brickmaker in Nepal
Please click on the above picture to see an adobe brickmaker in action. These people have been making bricks for generation. They can make upto 500 bricks a day. Its ironic they make so many sun dried bricks in a day yet its hard to buy the bricks , its because all these bricks are later burnt in a kiln. Since burnt bricks are more expensive then the sun dried bricks (almost 1000% more), brickmakers are reluctant to see them. Sun dried bricks alone, are unfortunately not used in construction anymore. Burnt bricks consume lots of energy to make and obviously during the process they produce lots of smoke. Furthermore, heat retaining capacity of clay die out when they are burnt. So the sun dried bricks are better thermally and ecologically then the burnt bricks.
