• Waste hierarchy includes prevention, minimization, reuse, recycling, energy
recovery, and disposal (in order of importance/priority).
• Major steps in waste management are reduction, recycling, treatment, and
disposal.
• Waste management and collection differ between countries, but many of the
African states do not have formal systems for collecting waste.
• Waste treatment is classified into three major types: physical, biological, and
chemical.
• Waste disposal methods include thermal (incineration, gasification and pyrolysis,
open burning, landfills, and dumps) and biological methods.
• Landfills are the most common way of waste management. The major advantages
are cost-effectiveness, ease of upgrading, and consistent monitoring.
• The disadvantages of landfills are that they cause environmental issues, including
infrastructural disruption and soil contamination.
• Incineration entails burning organic waste, which minimizes waste volume.
• The 3Rs (recycling, reducing, and reusing) are crucial for waste management.
• The sustainability principle encourages companies to improve their environmental efficiencies.
• The major benefits of waste management are socioeconomic, environmental, and
inter-generational equity.
• In Africa, the major challenges are outdated collection systems, poor management, ineffective governance, weak institutions, and a lack of support.
• A holistic approach to waste management is necessary for building safe, inclusive, and sustainable cities.
• Plastic pollution needs to be addressed to reduce the menace they cause on the
environment.
• Various methods can be applied to recycle waste in schools.
• Tom Szaky’s TerraCycle provides insight into how individual efforts can contribute towards a more sustainable planet.
• Smart African cities will attain zero waste and reduce operational costs.
• In Europe, technology will revolutionize waste management, and the techniques
used will be locally appropriate.
• In Asia, smart companies could help reduce costs and make recycling easier.
• In North and South America, integrated waste management will become common, while Australia will be characterized by the adoption of better technologies
and recycling techniques.
