For a group of Launceston students however, the past week saw them doing exactly that.

All up, 16 proposals were put forward by Scotch Oakburn College grade 10 students as part of a five-day "STEAM Project" challenge - taking concept pitches through to fully fledged business cases and concept designs.

One of the projects, dubbed Olympus Designs, would build fossil fuel-free sustainable housing with compressed plastic bricks, convection current heating and optional miniature pumped hydro systems.

Chloe Richman, who worked on the project with classmates Bronte Legro and Jess Finnigan, said the group recognised the average Australian home generated more than seven tonnes of greenhouse gas emissions each year.

"So we aim to reduce that as much as we can," she said. "And it will be much cheaper to run each year."

Another group sought to reduce the amount of single-use plastic in the agricultural industry by devising a hemp-based plastic to wrap silage - a form of livestock feed.

"Farmers wrap your silage in a normal plastic wrap, but at the end of the day you can't really recycle that or reuse it," said Hamish Auton, a member of the group behind the proposal, called HempWrapTas. "You've either got to burn it or put it into landfill."

"And so we had a look at some ways we could benefit the farmer and the ecosystem at the same time."

Luke Hammond, the school's grade 9 and 10 coordinator, was amazed by the effort the students had put in to the work over the week.

"The best thing has been seeing student's ideas, because they are so incredibly creative," Mr Hammond said.
