Employees of African Recycling transport bags of plastic waste at the recycling centre in the industrial zone of Mghira, near the Tunisian capital Tunis. Between four and seven per cent of the North African country's waste is recycled, official figures show. "When I see plastic, I see money," says Tarek Masmoudi, owner of one of the few recycling companies in Tunisia, where a waste crisis is threatening widespread social unrest. About 85 per cent of that ends up in landfills, while much of the rest winds up in informal dumps, says Tunisian waste management expert Walim Merdaci. But with many waste processing centres close to overflowing and neighbouring communities up in arms, the crisis is already stoking tensions. In November, a man died as security forces fired teargas to disperse protesters demanding the closure of a stinking landfill they say has spread deadly diseases and health problems to their town of Agareb, near second city Sfax. That could be a worrying sign of things to come, expert Wassim Chaabane says, as most of the country's 11 official dumping grounds are due to close by the end of 2022. That has authorities scrambling to find new sites. In the capital Tunis, home to about 2.7 million people, the situation is particularly urgent. The Bordj Chakir dump, Tunisia's largest, receives more than 3,000 tonnes of rubbish a day and is close to overflowing. But where others see a crisis, Mr Masmoudi sees an opportunity. Every day, a steady stream of minivans and small trucks bring to his centre in Mghira, near Tunis, bales of plastic waste to be weighed, sorted and cut into fine chips for industrial use. Much is collected by hand from the streets and bins of the capital by "barbechas", informal waste pickers. Mr Masmoudi's company African Recycling deals with 6,000 tonnes of waste a year. The 42-year-old directly employs about 60 people, many of them women, and indirectly provides work to roughly 200 - no small achievement in a country suffering 18 per cent unemployment. Between four and seven per cent of Tunisia's waste is recycled, official figures show. But Mr Masmoudi says the waste market is growing fast. "Recycling is a sector where a lot remains to be done, but which could create jobs and wealth in Tunisia." In Tunisia, after a decade of political paralysis since a 2011 revolution, Mr Masmoudi says the waste management system reflects a lack of strategy and vision. Companies like his are blocked from collecting trash directly, as "municipalities own the rubbish", he says. "The state pays 150-200 dinars ($52-$70) per tonne of waste that goes to landfill. We're paying money to bury something that's worth a fortune." But introducing a system of sorting could take years, says Mr Chaabane. "Tunisia's waste management system is hopeless at all levels, but especially when it comes to collection." The national waste management agency recently admitted that it lacks the resources. Mr Merdaci says Tunisian authorities want to bring in a combination of mechanical and biological methods to treat waste, compacting and composting it while collecting methane, gas which can be used as fuel. But initial projects will take at least two years to get off the ground. "Time is running out," he says. Mr Merdaci is calling for "a tax to pay for waste management and to make everyone pay for what they produce" as a means for municipalities to deal with waste. Each Tunisian produces on average 365 kilograms of waste per year, yet taxpayers are charged no more than 28 cents for its management. Mr Chaabane says urgent solutions are needed, and adds that incineration is "the best option for cities" if clean energy is used. But that option would not come cheaply, with incinerators costing some $280 million each. To Mr Merdaci, the outlook is grim. "We've had 10 years of political instability, a decade without any decisions, problems with those living near dumps, and a lack of money. Success is nil."
