In conventional toilets when someone goes for toilet the latrine and the urine(waste) fall on the track and leads to in-hygiene and dirtiness. Under the Swacch Bharat Abhiyan conventional toilets to be replaced with a green toilet ( green toilet means(EFTS) environment friendly toilets system). There is two types of the EFTS, 1. the bio-toilet system 2. zero discharge toilet system. In the bio-toilet system, human waste is converted into liquid and gases. The gases get mixed with air and liquid is discharged on the track. In the zero-discharge system, solid and liquid waste is separated and removed at the stations.
Is this a good answer ?
