As part of its Go-Green campaign, the Guardsman Group has embarked on a replacement of sewage-treatment plants at its offices islandwide.

One of the problems the company faced in its Montego Bay facility for a long time was the malfunctioning septic tanks and the tile field, which resulted in frequent overflow of sewage.

With the advice and assistance from the Scientific Research Council, Jamaica, an appropriate solution for the problem was found, and a 50-metre cube biodigester and a reed bed were installed. The installation was completed in the early part of this month, and the project commissioned on June 10. Neil Robinson, chief financial officer, Guardsman Group, presided over the unveiling ceremony.

The process

The biodigester septic tanks totally rely on the biological breakdown of the organic waste. The digestive process is carried out by putrefactive bacteria, which breaks down organic materials under anaerobic conditions. This technology provides an environmentally friendly method of treating the waste water within emission standards prescribed by the National Environment and Planning Agency (NEPA).

There are two major by-products of the new system - bio gas and nutrient-rich effluent. Bio gas can be used in the same way as LPG - for cooking and heating, etc. The nutrient-rich "grey" water - which is fully treated - can be used for irrigation and washing purposes.
