Punish severely those who still use polythene

Editor, I was surprised to read in yesterday’s The New Times that people are still using the banned polythene. How could the seven business operators in Kimihurura, who were on Tuesday fined Rwf 20,000 each for using polythene bags, expect to have gotten away with it? I wonder if they weren’t aware of the ban. It’s been a few years since this material was banned within our borders, so for them to plead ignorance is an impossibility.
