Waste collection and processing
• Source-separated waste collection at household (HH) level was introduced and implemented in accordance to the training which was conducted.
• The composting method is aerobic decomposition.We use aerobic composting method adopted from Guinea (BOKU-University Conakry project) as a best practice for this project.
• 1200 Kg – 1500 Kg of household waste (Mixed) is delivered weekly at the site through the collectors .
• Organic portion 90-95 %.

Compost application and Urban Agriculture practice
• By applying compost the soil structure and fertility was upgraded.
• Different vegetables were planted and the crop yield was very good.
• Furthermore, the site has a show room effect.

In cooperation of Mr. Hiwot from Good to Grow Plc implemented thefollowing theme in the selected schools:
Compost -> Soil fertility -> School gardening -> Nutrition -> Food security
With the goal to educate children on :
• SWM on use of organic waste as a natural resource rather than directing the waste to the landfills (Koshae).
• Integrate SWM across many areas of the curriculum to help develop student capabilities in the following key competency areas (Social Science , Biology, Mathematics , etc…)
Urban Agriculture Practice in Schools

• The School gardening result was very encouraging. • The vegetables were then served to orphans and given to parents with very
low income.

Household Survey
AEEG carried out the survey which included 150 households and 10 collectors in KK Sub city area who are part of the pilot composting project.
The survey results can provide:
• The survey will help gather information on HH-SWM ,the costs involved, and how those costs are paid for.
• The survey results can provide a baseline and guidance for SWM in an efficient, cost effective, and environmentally preferable manner.

Market Survey
• To assess households’ willingness to pay for compost.
• To identify factors affecting the WTP (Willingness To Pay) for compost made of HH waste.
• The findings of the study will generate valuable information to producers and other stakeholders operating in SWM Urban Agriculture areas.

Training of school community and waste collectors
The workshop was conducted on at Abune Basliaos school, Addis Ababa, Ethiopia.
• The main topics were source separated waste collection, compost production, compost application, urban agriculture and food security.
![Page 24: Sustainable Solid Waste Management - AgriProFocus · work by composting organic waste and using it in urban agriculture activities. • This will ultimately assist in meeting the](https://reader034.fdocuments.net/reader034/viewer/2022052102/603bebf0197ca77492703d43/html5/thumbnails/24.jpg)
• The waste collectors will have the possibility to add value to their daily work by composting organic waste and using it in urban agriculture activities.
• This will ultimately assist in meeting the MDG.
• The school community i.e. students, parents, teachers will benefit from this project and will integrate SWM and UA in their environment Protection program.
• Great opportunity to create awareness in good solid waste management to a wider public, go from pilot project to major project, work with other NGOs.

The Workshop was conducted in four modules, one training session per week.
• Implementation of the 2012 Workshop.
• The Workshop was designed to transfer the knowledge and experience gained from the KK Pilot Composting Project to new waste collectors, teachers , students and the school community.
• The main topics were source separated waste collection, compost production, compost application, urban agriculture and food security.
Training of Trainees (ToT) on SSWM
![Page 27: Sustainable Solid Waste Management - AgriProFocus · work by composting organic waste and using it in urban agriculture activities. • This will ultimately assist in meeting the](https://reader034.fdocuments.net/reader034/viewer/2022052102/603bebf0197ca77492703d43/html5/thumbnails/27.jpg)
The following specific outputs were achieved:
• The workers at the site will be trainers of trainees (ToT).
• Waste collectors will have the opportunity to add value to their daily work by composting organic waste and using it in urban agriculture activities.
• The experience and data obtained will be an asset and knowledge source for institutions working on SWM and environmental issues.
• SSWM will then be adopted in different Schools in Addis Ababa.
• The school community, i.e. students, teachers and parents will benefit from this project and will integrate SWM and UA in their HH and environment Protection program.
