On top of municipal solid and gardening wastes and black waters, is there any other source of energy within the municipal services scope of activities?

Yes, there are. Grey and rain waters are a very adequate source or sink of heat, which can be used to taking or pouring heat in HVAC applications and domestic hot water preparation. Obviously, heat transfer must be boosted by a water-to-water heat pump. The efficiency of those systems can reach up to 5-6, depending on the temperature jump. Water-to-water heat pumps can save up to 10 times the primary energy needed for space heating and cooling applications in comparison to fossil fuel-powered boilers.
