The school's grade-six pupils are the driving force behind the school's bid in the state-wide Rubbish Free Lunch Challenge.

The pupils designed posters to promote environmental awareness, invited guest speakers to the school and held a special environment liturgy.

In line with the concept's rules, the students were banned from bringing food with packaging to school and instead brought lunch in plastic containers and ate more nude food such as fruit.

As a result, the school has significantly reduced its waste and there's barely a skerrick of rubbish in the playgrounds.

The Rubbish Free Lunch Challenge is a joint initiative of Sustainability Victoria and the Department of Education and Early Childhood Development.

The challenge is to become more resource smart and reduce waste from school lunches.

Participating schools are eligible for prizes, including $2000 for the winning primary and secondary schools.

Smeaton Primary School will use the challenge to enhance its pupils' understanding of how their daily activities affect the environment.

Principal Phonse Liddle said the school hoped that the challenge would lead to a dramatic reduction in lunch packaging and rubbish.
