ST Marcellin Primary School became the second school in Suva to launch the waste management initiative.
School principal Jone Benedito said implementing the three Rs — reduce, reuse and recycle — would build a healthy learning environment for the students.
"Our rubbish at the moment is being taken to the incinerator," Mr Benedito said at the launch on Wednesday.
"Now we are working with the Fiji Environmental Law Association and other partners to help make our school environment more sustainable and healthier for our students."
He said as of yesterday, there would be separate rubbish bins for paper, plastics, empty cans and bottles.
"This will make our environment healthy. When we used to burn our rubbish, we polluted our air and smoke from that and it was unhealthy for the students.
"In order to promote a good learning environment, we also have to have a clean environment and this is the first bold step towards it."
Mr Benedito said students were responding well to the changes.
He said he hoped the students would practise what they learnt at home.
"Schools need to come on board and take on this initiative because we will stop polluting the air and children will be healthy when they are in the school environment."
Nehru Memorial Primary School was the first school to implement the three Rs concept.
