Only if they are actually working!
Lagos state had a rice mill in imota that produced really good long grain rice and food grade rice bran.
Stopped production about 4+ years ago.
Supposed to restart as a PPP.
Has it restarted? Don’t know.
Cant waste anymore time going to check.
And phone calls do not get an answer.
Use rice bran in mushroom production and good quality bran is best.
