We have two types of ”trash” in the world, organic and non-organic, and in Myanmar these are typically mixed and sent to landfill. Clearly, all non-organic materials such as plastics, metals, paper, glass etc should be collected and recycled, but currently there is no clear solution for organic waste. Anything that has come from the soil should be returned to the soil if the equation is going to hold, and bokashi is a good way of making that happen.
In Yangon, the soil is typically sandy and low in nutrients; often it has been badly treated with chemicals. The way to build a good soil for agriculture, urban or otherwise, is to increase the carbon content (humus), and this is done by adding organic matter.
