waste water

“We already had rum distillery waste water so we decided to put that with sargassum and see what happened.”

Biologist Shamika Spencer was hired to experiment with differing amounts of sargassum and waste water to figure out which combination produced the most biogas.

The Construction Employers Federation has criticised the Department for Infrastructure and NI Water over thousands of homes which cannot be connected to the waste water system.

The organisation said that the situation with waste water in Northern Ireland was a "fiasco".

O'Dowd would not be drawn on questions of specific new build developments which are yet to be connected to the waste water system, and said: "You've clearly done a lot of research which you could have shared with me beforehand, you chose not to."
