Defeating limp liners
Wheelie bin waste thrown onto sagging garbage bag liners was a messy problem at Ramingining School. Then a way of clamping the drooping inserts upright was developed.
Three students in the Work Ready Program devised a simple solution: a Perspex clip. The retaining device locks together the edges of the five rigid bins and the flimsy plastic bags .
Inventors Osmond Gaykamangu, Andrew Malibirr and Jarius Durrurrnga first devised a cardboard template, shaping and reshaping the pattern until a successful model emerged.
Manual arts teacher Francois Du Plessis said the trio researched similar bin bag clips using Google Images and YouTube.
“There was a lot of trial and error, but eventually the students had a shape to submit to our laser cutter,” he said.
“The cutter made mass production of the fasteners possible, and 100 were made in 20 minutes.
“By preventing the escape of food scraps and plastic into our bins the click-on clips are solving a five-year problem.
“The durability of the clasps in different weather conditions will be monitored. Perspex is totally waterproof and can withstand UV radiation, but it may degrade after years of exposure to the Sun.”
Mr Du Plessis said students in the Work Ready Program are also working on school signage, benches for breezeways and storage containers.
The program aims to prepare students for the workforce by boosting their employability skills, including workplace etiquette, listening, reading and following instructions, working in teams, financial management, design and fabrication.
