Using old garbaged materials found in the junkyard on site we built a raised worm farm sink system.
A sign was put next to the installation which described the process of building it in seven languages. This simple technology enables people to create organic fertilizer wherever they live. A worksheet describing bioaccumulators and biodynamic compost plants accompanied this. A version of the sign was also published in the Pathways magazine.
Here is one of zariats incredible pictures.
