The Justa stove is an improved cook stove that works like a rocket stove but adapted for indoor use and family cooking needs. It is designed to solve environmental issues such as climate change and deforestation produced by the inefficient and dangerous traditional open fire cooking.

Steps[edit | edit source]
Build the stove body from either adobe, brick or cement block, guiding yourself with the measurements shown in Drawing 1. The stove in this example is made of adobe with a mud mortar
Lay the milk can, with the bottom already cut out, on a little bit of mud in the space indicated by the drawing. Leave the walls of the stove leveled with a constant height of 11.5"
Frame the plancha with the strips of cardboard, and fill the space between the two frames with either cement or a damp, compacted mix of earth, sand and construcion lime
Rest a chimney tube on the two diagonal lengths of rebar and seal it in with earth or cement as shown in the drawing.
Build a 20" long, U-shaped sheet metal tray to catch wood ash falling from chimney - insert through can.
