The COMPED's Composting in Battambang Municipality


1 Introduction

The city of Battambang has introduced a large scale of composting based on similar practices in Phnom Penh. The plant was financed largely by the German Federal Ministry of Economic Cooperation and Development, and partially by Thuringian-Cambodian Association (TKG). Until the end of 2010, it was run under Soziales Abfallzentrum Battambang (SAB)/Social Waste Management Centre. Nowadays, it is independently operating by COMPED on Battambang city owned land (8,000m2) as shown in.



COMPED's composting plant has been in operation since the introduction of the new dumpsite of Battambang city. Market waste delivered to the plant comprises of 84% organic (fruits and vegetables), 8% plastic, 3% paper, and 5% others.

2 Open Windrow Composting:

The organic waste that can be composted is as below:

  • Kitchen waste: Waste of vegetables, fruits, residue of coffee, residue of tea, egg shell, waste of food, ash, paper.

  • Garden waste: Flowers, grass, leaves and branches.

  • Agriculture waste: green waste (banana leaves, lotus leaves, straw, seedling…etc.)

  • Animal dung such as from cows, buffaloes, chickens, pigs…etc.

  • Other green plants: Hyacinths, waste of green plants, etc.

  • Market waste: green waste (vegetables, fruits, sugarcane peel…etc.) and food waste.

The quality of compost is regularly analysed in Germany. The latest analysis done in January 2014 is able to review via this link below. It can be stated that the quality of compost products produced in Battambang by COMPED is very good for soil improvement and exceeds the legal Cambodian threshold values. It is applicable as a high quality organic fertilizer.

3 Conclusion

The financing of a proper municipal waste management needs a high priority if the waste management should be sustainable. It shall fall within the prioritized national development projects. Therefore the central government units need to encourage the improvement of the current waste management situation in Cambodia in general at the level of the local authorities.


Because of high demand of compost in Cambodia at the moment, Phnom Penh's municipal waste has huge potential to supply such demand by composting organic waste from main markets and quartiers of the city. Waste separation at source could be promoted at the main market as an initial step, which would help to increase practical implementation of composting, while at the same time preventing a certain amount of waste from entering the dumpsite.


However, "prevention is better than cure", therefore, 3Rs principle is highly appreciated in managing solid waste system trying to reduce waste generation, reuse it and promoting actively waste separation at source. Last but not least, it is important to transform "waste" into "valuable resources" with convenient and feasible technology such as composting. Ultimately, not only Phnom Penh, but also other cities of Cambodia can reach "Zero Landfill" some days in the near future.
