Air Pollution & Toxic Effluents: The hidden cost of Senegal’s new incineration plants

Senegal’s rapid urbanization and industrial development have come at a price: soaring air pollution. To address this crisis, the government has embraced waste incineration as a solution, but this apparent "fix" comes with a dark secret – the detrimental impact on air quality and the environment.

The hidden costs:

Incineration releases a toxic cocktail of pollutants into the air:

  • Dioxins and furans: Cancerous and persistent organic pollutants (POPs) found in plastic and other polymers.
  • Heavy metals: Arsenic, lead, mercury, and chromium – harmful to human health and the environment.
  • Particulate matter (PM): Fine dust causing respiratory problems and reducing visibility.

Environmental Consequences:

These pollutants infiltrate the air, water, and soil causing:

  • Health problems: respiratory illnesses and cancer.
  • Damaged ecosystems: acidification and eutrophication.
  • Reduced visibility and solar radiation.
  • Increased climate change contributions through greenhouse gas emissions.

Health impacts of air pollution:

Air pollution has devastating health consequences:

  • Increased mortality rates associated with air pollution exposure.
  • Exacerbated respiratory and cardiovascular diseases.
  • Impaired cognitive function and learning.
  • Skin and eye irritations.

Senegal’s approach criticized:

  • Inadequate waste segregation and infrastructure unprepared for high-volume incineration.
  • Lack of public consultation and participation in decision-making processes.
  • Overreliance on a technological solution rather than focusing on prevention and waste reduction strategies.

Alternative Solutions:

  • Expanding recycling and composting programs.
  • Investing in renewable energy and energy efficiency.
  • Embracing circular economy principles.

The looming threat

Though air pollution has become rampant, little attention has been given to the impact of the toxic effluents of incinerators. These contaminants fester in soil and water sources, leading to:

  • Increased soil salinity and fertility decline.
  • Polluted water with heavy metals and organic contaminants.


Senegal’s pursuit of quick solutions through incineration might actually accelerate environmental degradation and exacerbate its air pollution crisis. Focusing on sustainable waste management approaches and promoting renewable energy & resource efficiency would offer a healthier and more lasting solutions.


Q: What are the economic costs of air pollution and toxic effluents?
A: The impact extends far beyond immediate healthcare costs, including productivity losses due to health problems, environmental restoration expenses and increased resource depletion.

Q: Are there any measures to mitigate these risks?
A: Implementing air quality regulations, promoting pollution control technologies and fostering community engagement in environmental decision making could minimize damage.

Q: What are the long-term plans to address air pollution in Senegal?
A: A shift to sustainable waste management, embracing renewable energy and encouraging recycling & composting programs would create a comprehensive and lasting solutions.
