The Implementing Sustainable Low and Non Chemical Development in Small Island Developing States (ISLANDS) programme is a $515 million five year initiative backed by the Global Environment Facility (GEF) supporting 33 SIDS across four regions: the Atlantic, Caribbean, Indian Ocean and Pacific to improve chemicals and waste management in their territories. ISLANDS is led by…
Today (9th April 2025) we organized and participated in the final workshop under the TWENEx Seychelles project held at the SAVOY hotel and Spa in Beau Vallon. The objective was to present the results of the project to stakeholders. The workshop was opened by the TWENEX focal point for Seychelles Mr. Rahul Mangroo also the…
This month we are helping with the installation of 4 imported membrane biodigesters and accompanying equipment at partner institution to complement the two locally made plants that we designed. One of these membrane digesters is a 2.65m3 plant for home use and installed at upper capuchins at Anse Aux Pins at the home of Mr.…
On Friday 21st March 2025, the ISLANDS project met with the Bills Committee of the Seychelles National Assembly. The activity was led by Ms. Iris Carolus the ISLANDS legal consultant supported Mr. Cliff Gonzalves the ISLANDS National Chemical and Hazardous waste expert who helped with the technical aspects of updating the legal framework as well…
We conclude our AD trials this month by using a standard LPG low pressure regulator instead of the refrigerant gas manifold as is being used by gas users for cooking. We did this by compressing biogas into a disused LPG tank. We were able to do this by sourcing a fillable gas valve that allowed…
We are now adding value to the digestate by converting it into an effective and safe liquid fertiliser that can be used for plants and food crops. The brown digestate undergoes primary sedimentation, a process whereby the large particles settle out of solution by gravity. This removes the characteristics smell of the product leaving a…
We may be the first to produce compressed biogas in Seychelles! On Saturday 15th February 2025 we continued where we left off by firstly brazing connectors to the fridge compressor and wiring it for use. Tests were conducted on the compressor and found to be in good condition. On the Monday flexible pressure hose was…
In January 2025, we were also looking at ways of compressing biogas so that it can be separated from the reactor and used elsewhere. How about for barbeque on the beach? Perhaps at a sports or other recreational event? We considered two storage options 1) an inner tube that will be expanded under pressure and…
On 22nd January 2025, our chemicals expert- Mr. Cliff Gonzalves-led a training workshop on inventory for chemicals listed under the Stockholm Convention on Persistent Organic Pollutants. The knowledge will help participants in their work being the Technical Working Groups (TWG) for the national inventory on Persistent Organic Pollutants (POPs). This activity is part of the…
We modified our medium plant yesterday 13.01.2025 and increased the dimension of gas tubes to half inch (using water garden hose). The idea is that bigger tubes will give more volume of biogas which will lead to better heating on the stove. We also tested the impact of distance from the digester to the stove…
