"It could also hurt the tourism industry because it's unpleasant for tourists to see people digging garbage for collection," Decommarmond said.
Currently, hotels, landfills and businesses are the only consistent collection point for PET and aluminum cans, as no specific services are available for collection.
There are five main shopping centres in the 115-island archipelago where collectors deposit their cans and PET bottles. Three are on Mahe and one each on Praslin and La Digue, the second and third most populous islands respectively.
Alvin Leste, who buys PET bottles and metal cans from street collectors, said the collection is a lucrative business.
"I sell it to the redemption centres every year and I usually get US$7400 (SCR100,000). However, it takes a lot of bottles to get that amount of money, " Leste said.
Some locals see another benefit to collecting PET bottles and cans.
"Since the arrival of informal collectors, mostly done by drug users, theft in the country has reduced," said a local citizen, Sheryl Athanase.
She added that "they should, however, be given gloves, masks and T-shirts for hygiene and identification purposes."
According to a report - Solid Waste Management in Seychelles - informal collectors can collect around 5,000 PET and cans per day.
Plastic bottles and aluminum cans are not biodegradable and can accumulate in landfills if not recycled.
