Tri-generation from vegetable waste
Waste production in Tunisia is increasing rapidly due to the socio-demographic development and the changes in consumption habit special in the urban areas.
From more than ten years Tunisia is working on the management of solid waste by the construction of controlled discharges and the valorisation of the waste.
Green waste, which constitutes a good raw material for the production of energy and organic fertilizers, valorisation is considered to be a very interesting field, in addition it helps avoiding the environmental problems that it generate in the discharge,.
This project is a limited pilot project, but it can be easily duplicated at a regional level thanks to the “common traditions” of MEDREC countries.
In addition to wholesale market, biogas generated in water treatment stations and public waste discharges can be valorised. The potential in Tunisia only is about 411 000 m3/day of biogas production in public discharges and 130 000 m3/day in water treatment stations.
Photovoltaic connected to electricity grid
The activities of Borj Cedria technopole concerns energy, water and biotechnology. Among the realizations that could materialize the interest, in relation to renewable energies, is the implementation of a grid connected photovoltaic plant (260 kWp) to cover the needs in energy for the streetlight of the technopole.
Solar water heating in hotels in Tunisia
Tunisia is endowed with good solar condition, and has started the exploitation of this potential for water heating since the 80s. The number of solar water heaters installed up to now in Tunisia is about 160 000 m² of which 8 000 m² in hotels (5% of the Tunisian hotels potential)
The installation of solar water heating systems will concern hotels using conventional energy resources (Gas, Liquefied Petroleum Gas and fuel) being subsidised by the Tunisian Government. The removed subsidy will help decrease the effect of the high hydrocarbon prices on sustainable development programs of the Tunisian Government
