Phnom Penh is facing huge challenges in waste management due to population growth, increasing income and consumption levels, expanding urbanisation and inadequate waste management. In this regard, with the request for support from Cambodia’s Waste Management Division of Phnom Penh Capital Hall (PPCH), IGES Centre Collaborating with UNEP on Environmental Technologies (CCET) has been providing technical assistance towards the development of a waste management strategy for Phnom Penh 2018-2035. The strategy is based on a holistic waste management approach. It addresses all waste streams (solid waste, liquid waste/ wastewater, and gaseous emissions), primarily focusing on solid waste and but also covering other forms within the mandate of Phnom Penh Capital Authority. In parallel with above, a quick study was done on Phnom Penh’s existing waste management systems and current practices including the waste flow, policies and regulations framework, waste management practices challenges, which provides practical recommendations for PPCH and other stakeholders for sound waste management in Phenom Penh.
