Renfrew High School
The team from Renfrew High School is called The Green Guys.
Their invention is a drone that collects litter from the Clyde. It is connected by four extendable recycled steel rods and is made of sustainable materials.
The group wanted to make sure it was made by sustainable materials so they could save as much litter as possible.
The Green Guys think their invention would bring a major improvement to the quality of life around the Clyde and the quality of the water because it would make the river cleaner and safer for animals and sea life.
