 Economic viability means that recycling cost must not greatly exceed disposal cost and that when recycling is provided for by the authorities, cost should not overburden businesses.
In addition, it is important to require the following:
 Recycling should not lead to dispersion or to a concentration of harmful substances in products and in the environment.
In legal terms, material recycling and energy conversion are similar. In other words, decision is determined by cost and technical feasibility and therefore rests in the hands of the waste producer.
In this regard, ANGED Sector Division plays a key role in the recycling program. Even in the case of hazardous special industrial waste, recycling is feasible in Tunisia when there is appropriate separation and separate collection and when the separated fractions meet the specific quality needs of production companies.
Currently, it is the case for the following wastes:
batteries and accumulators;
used lubricating oils and used filters ;
tires.
The sector of electrical and electronic waste and of waste from the health sector is being prepared. Energy conversion is not fully developed in Tunisia yet. It is especially important to avoid highly toxic calorific fractions to be recycled in thermal power plants. It is therefore essential to develop quality standards for these secondary fuels.
In the future, pre-treated waste combustion in power plants and cement factories can result in a violent development of techniques for separation of calorific fractions of regular quality collected from household and industrial waste to convert them into energy.
