Resource efficiency and sustainable waste management

Despite being a relatively small country, Tunisia’s water resources are especially scarce. and while the country is hard at work trying to cover the needs of a growing population and demand, Tunisia still cannot properly make use of non-conventional water sources. Mona Lamine wanted to help create other means of providing water so she developed ecological and sustainable solutions for water recycling in urban and rural areas through her company, Elma Eco.

The idea came to Lamine, an environmental engineer who had a professional experience in water treatment in two research laboratories. The solutions are basically ecological water treatment devices that rely on filtration by plants and natural materials such as laterites (iron-rich soil).

“The purpose of water treatment devices is to discharge clean water into the environment to prevent groundwater contamination by toxic pollutants and protect the marine environment against eutrophication (having a lot of nutrients).

According to Lamine, these devices make it possible to recycle water for irrigation and watering gardens. “They present several ecological benefits such as the reduction of drinking water consumption, fighting against global warming and the enrichment of biodiversity,” she says.

This biotechnology can serve isolated homes, residences, municipal buildings and manufacturing plants for dairy products and fish farms.

Lamine was part of the SwitchMed Training Program. “Thanks to SwitchMed, I decided to push my research and build a wastewater treatment system in my own home. Since the system has to meet several requirements such as operation low cost, minimum energy consumption and high purification efficiency, I opted for the treatment with plants through the introduction of a natural material,” she notes. “After several tests on natural materials, I found that the filters planted with the alpha wires are the most favorable for a high purification efficiency.”
