The landfill, funded by the European Union, is located in Providence on the east coast of the main island of Mahe. It covers an area of 26,000 square metres and has containment areas of 3 metres in height, with up to 4 metres on the side facing the sea.
Alain Decommarmond, Secretary General of the Environment, said the new landfill is one of the best in the region.
"Seychelles continues to strive for more effective disposal of solid waste, but at the same time is exploring strategies to reduce the generation of waste in landfills," Decommarmond said.
The landfill has three drainage channels for the collection of liquids called "leachate" - a black liquid containing organic and non-organic elements. It is created when landfill waste decomposes and is washed away by rain.
About its expected function, Decommarmond said that it already serves as an educational institution for students and locals who want to learn about waste management.
Seychelles' first landfill in Providence was opened in March 2015 under the 9th European Development Fund.
