Sanitation, Waste Management & Pollution Control
Solid and liquid waste classification, plastic pollution, open defecation, diseases associated with poor sanitation, recycling, and the circular economy in Ghana.
The June 3, 2015 disaster at the Kwame Nkrumah Circle in Accra—where a twin fire and flood explosion claimed over 150 lives—was largely aggravated by choked storm drains packed with single-use plastic waste and discarded polythene, which blocked the natural outflow of the Odaw River into the sea.
Key Syllabus Learning Objectives
- 1Classify types of waste and distinguish between biodegradable and non-biodegradable materials
- 2Examine the root causes of poor environmental sanitation in Ghanaian municipalities
- 3Evaluate the health, social, and economic consequences of improper waste disposal
- 4Explain the principles of Reduce, Reuse, Recycle (the 3 Rs) and composting
- 5Recommend proactive behavioral and institutional reforms to make Ghana's cities clean and flood-free
Plastic Menace, Open Defecation & Drainage Choking
- Plastic Waste Dynamics: Single-use plastics take over 450 years to degrade; they fragment into microplastics that poison fish and agricultural soils.
- Open Defecation Drivers: High poverty, poor enforcement of building regulations (landlords renting apartments without toilets), and inadequate public latrines.
- Vector Breeding: Clogged gutters create stagnant, foul-smelling water ideal for Culex and Anopheles mosquito proliferation.
The Greater Accra Metropolitan Area (GAMA) Sanitation and Water Project, funded by the World Bank, has provided over 40,000 subsidized bio-digester household toilets to low-income urban families.
Uncontrolled plastic disposal and open defecation are direct triggers of urban flooding and cholera outbreaks.
Sustainable Waste Solutions: The Circular Economy & Enforcement
- Source Segregation: Sorting waste at household level into organic, plastic, paper, and glass bins.
- Plastic Upcycling: Companies in Ghana mix shredded plastic with sand to manufacture heavy-duty, earthquake-resistant pavement bricks.
- Sanitation Enforcement: Reviving the 'Samasama' (Town Council Sanitation Inspectors) system and prosecuting sanitation offenders in specialized municipal courts.
Local recycling enterprise Nelplast Ghana manufactures ecological pavers and manhole covers from collected plastic waste and quarry dust.
Waste is wealth when segregation, recycling, and strict law enforcement are systematically institutionalized.
- In WASSCE, distinguish clearly between solid waste management and liquid waste disposal methods.
- When explaining the 3 Rs, define each 'R' (Reduce, Reuse, Recycle) with a distinct real-world example.
- Mention the role of District Assemblies and sanitation by-laws when answering institutional questions.
- Using the terms 'Reuse' and 'Recycle' interchangeably (reusing involves using the item again as is; recycling involves industrial reprocessing).
- Attributing sanitation failure solely to the government, ignoring citizen indiscipline, indiscriminate littering, and negative attitudes.
- Overlooking the link between choked drains and perennial urban flood disasters.
- Can I classify waste into solid, liquid, and gaseous categories?
- Do I know the difference between biodegradable and non-biodegradable waste?
- Can I explain how the 3 Rs work in waste management?
- Can I list 4 health and 4 economic consequences of poor sanitation in Ghana?
