Environmentally Friendly Waste System

In our final year project, we will be working to extend on the project of an environmentally friendly system to handle waste recovery. In this project, the main idea would be to use human waste and convert it into a suitable manure to be used in plant growth.


This would be done using a 2 stage digester in which the waste would be loaded into the top and it would be process through an anaerobic process and later dropped to the bottom stage where it would undergo an aerobic process. The final product would be a fertilizer that can be used to grow crops in farms.

As a continuation of this project, we are planning to harvest the methane gas for usage as fuel in the third world countries. Methane gas is the byproduct in the anaerobic stage. In order to harvest the pure methane, we would be required to extract all other gases produced by the anaerobic process. This includes carbon dioxide and hydrogen sulphide. The most basic method would be to use water to absorb the other gases which are more soluble than methane.

This project can be traced back to the needs of the third world countries. This system is crucial because at the current moment, the waste in the third world countries are not being properly treated and thus, the living conditions are extremely unhygienic. In addition, by providing methane as a source of fuel for these third world nations, it would lower the burden of paying to buy fuel gas for daily usage.

We would be conducting most of our experimental runs at Singapore Vision Farm located in Chua Chu Kang and the testing of samples would be done in Ensure Engineering’s lab in Tuas.
