Biomass is a source of power generation. Organic materials of plant (including microalgae), animal, bacterial or fungal origin are used as a source of energy. With a view to working towards energy transition, ANME has been using this clean power generation process since the 1980s.
Referring to the national energy audit for 2017, biomass production in Tunisia was estimated at around 1,085 ktoe, equal to 18% of national primary energy production. About 35% of this biomass production is used for making charcoal.
The National Waste Management Agency (l'Agence Nationale de Gestion des Déchets – ANGED) estimates that Tunisia produces around 6 million tonnes of organic waste per year: 2.2 million tonnes of household waste, 2.2 million tonnes from farms and the agro-food industry, 1 million tonnes from olive oil pressing, 400,000 tonnes of poultry droppings and 200,000 tonnes from wastewater treatment. ANGED estimates the annual potential for power generation from bio-waste at around 1,000 GWh.
The Tunisian Solar Plan has set as an objective, the creation of biomass power generation capacity of 100 MW by 2030.
It should be noted in this context that as yet, only a few biomass digesters have been set up in Tunisia, most of which are at ONAS purification stations.
