Pilot Project to Promote Organic Waste Utilization for Climate Change Mitigation in Battambang City, Cambodia: promoting organic waste separation at source for composting

Chau, Kim Heng

A participatory pilot project is implemented based on the result of group’s discussion and brainstorming at the training workshop that carried out in Phitsanulok Municipality, Thailand. After returning to Battambang, Cambodia, a working group was formulated by the trainees in August 2012. Members of the working group include representatives from the Battambang City, COMPED, CINTRI and market’s committees. A local directive was formulated through dialogues and discussion among the working group’s members and announced to the public to promote organic waste separation at source for composting. Numbers of awareness raising activities and stakeholder’s consultation were carried out from time to time to facilitate the pilot project implementation. Activities of waste separation at source were carried out at three main markets in the city. Project monitoring and evaluation was carried out every two months to ensure the progress of project implementation. Regularly, challenges and problems occurred during the implementation is solved through stakeholder dialogues and negotiation, for example, based on dialogues, CINTRI reduces disposal fee for market that separated the organic waste as the cost for landfill operation is decreased, waste bin distribution for collection of organic waste upon request of the market, broom is provided by CINTRI to market cleaner as incentive for separated collection of waste that being separated, etc. All incentives that given to the stakeholders were not designed by the project but it were from the dialogues between the working group and stakeholders. Many of items were given by local stakeholders considering benefits and sharing. This clearly illustrates that the local stakeholders feel their ownership to the project.
As of a result, around 30% of fruit and vegetable vendors at Phsar Thmey, 15% at Phsar Nat and 35% at Phsar Boeng Chhouk, have participated in the waste separation at source by putting separated waste in plastic bags or small containers. Markets cleanliness has improved. Organic waste delivered to the composting facilities has increased both in terms of quality and quantity. The quantity of waste to composting plant was increased from 25 tonnes (1% of total waste) in August 2012 to 139 tonnes (7% of total waste) in January 2013. Labour requirement for waste segregation at the composting site has decreased. The productivity of the composting plant has improved.
This project has significantly decrease greenhouse gas (GHG) emissions through composting. GHG emission reduction has gradually increased from 5.7 tCO2-eq per month in August 2012 to 31.5 tCO2-eq per month in January 2013. This reduction is mainly from avoided landfill of organic waste and not yet including the contribution from potential GHG saving from use of composting and replacement of chemical fertilizer for cultivation.


This pilot project is being continue.
