Oresanya said the authority had started the process for the final wind down programme of the site.
“The first thing we are doing, in this direction, is the covering of the earth and the landscaping of the site.
“We have six years of active refuse dumping and the last year of it will be the final cover by 2022.
“This place will be turned to a green park and used for various things like a golf course and recreation centre.
“The electricity that will be used in this place will be from the methanegas generated at this site,’’ he said.

Oresanya explained that a Boston based company in the U.S. had been contracted to execute the project.
