Morocco's commitment to the development of renewable energy was confirmed at COP 22 (Conference of Parties) in Marrakech, during which Morocco announced the decision to increase the share of renewable energies from 42% of installed capacity planned for 2020 to 52% by 2030.
Morocco's energy strategy, which attaches great importance to the development of renewable energies and energy efficiency, is based on four fundamental objectives, aimed at:
- Enhancing security of supply and energy availability;
- Generalized access to energy at competitive prices;
- Demand management;
- The preservation of the environment.
Among these renewable energies is biomass.
Household waste in Morocco contains almost 65% to 75% organic matter, so a very large amount of biomass.
Waste recovery is the most optimal waste management solution. It not only eliminates the large quantities of waste produced every day, but also generates the energy needed by a constantly changing population.The objective of this research work is to assess the household waste potential for electrical and thermal energy generation in Fez city (Morocco) using two modes of energy recovery: combustion and anaerobic digestion.
The maximum electric generated was 228.04 GWh/year from direct combustion of household waste, whereas for thermal energy, a maximum value of 633.46 GWh/year in 2016. For anaerobic digestion, the maximum electric generated was 50.02 GWh/year and thermal energy generated was 75.79 GWh/year in 2016.
