Les pays du Sud possèdent des immenses ressources solaires, éoliennes, géologiques ou forestières ; celles-ci sont valorisées sous forme de matériaux, de produits diversifiés ou utilisées  à des fins énergétiques. De nouvelles technologies permettent aujourd’hui leur exploitation  de manière rationnelle et durable.

« En 2015, les investissements dans les énergies renouvelables ont été plus élevés dans les pays en développement que dans les pays développés », souligne le Programme des Nations unies pour l’environnement (PNUE). Il est prévu que la population mondiale, qui comptait six milliards d’habitants en l’an 2000, augmentera de 50 % pour atteindre les neuf milliards d’habitants en 2050, 90 % de cette augmentation devant être localisée dans les pays du Sud.

This technology is based on a solid-gas thermochemical reaction that stores directly the thermal energy from the sun in order to transform it for cooling purposes. DACSOL system is the first completely autonomous (offgrid) solar-based air conditioning solution on the market.

In this invention, the heat generated by the composting of a first batch of waste or organic residue is captured and used to simultaneously dry a second batch of waste, compost or digestate.

This technology can produce in an easy and efficient way, an Ethyl Esther Biodiesel from vegetal oil (oil of Jatropha Curcas seeds or cotton or sunflower), ethanol and a natural catalyst (made from shea nuts shell or other local biomass specifically designed for the purpose of this process).

The production of 2nd and 3rd generation biofuels is still limited. Accordingly, biofuels made from organic waste readily available at negative cost are appealing. The innovative process described below can be integrated into existing AD (Anaerobic Digestion) waste treatment units.

This innovation consists in a solar beam collector device associated with a parabolic heliostat with a plane mirror sensibly configured « beam-down » The device offers a concentration of the intense solar heat energy nearby and very close to a receptor (hot point of use) which is located underneath. Furthermore for specific thermal needs, an over-concentrating device can be added without any compromise: temperatures over 500 °C and thermal powers of 20 kW can easily be produced and exploited.
