Summary of Study Session 22
In Study Session 22, you have learned that:
- In rural communities of Ethiopia, the type of waste produced is mainly agricultural and household waste, which is organic and compostable in nature.
- There are several different ways of classifying waste, including putrescible or non-putrescible, hazardous or non-hazardous, and combustible or non-combustible.
- Hazardous chemicals such as obsolete pesticides are concerns in rural communities.
- The functional elements of solid waste management are onsite storage, processing and handling, collection, transfer and transport, resource recovery, and final disposal.
- Landfill as a means of disposal of solid waste is used in urban situations but may not apply in rural settings. Controlled tipping/burial and composting methods are preferred.
- Disposal of plastic bag wastes (festal) is a cause of concern and needs special attention to be managed sustainably.
- Care should be given in selection of disposal sites at residential or communal level.
- Surveying and community involvement is needed in order to prepare viable action plans to improve solid waste management practices.
