Cali Announces Plans for a New Waste Management Model

Cali, Colombia — Pablo Lopez and Michael LaGiglia, International Policy Analysts for the Center for Clean Air Policy (CCAP), accompanied Cali’s acting Mayor Diego Calero (City Health Minister) and Director of Cali’s public waste company Maria del mar Mozo as they announced plans for the City of Cali to introduce a new waste management model which will be implemented in the coming years. CCAP has worked closely with Cali to facilitate the implementation of these efforts with support from Environment Canada, Kingdom of Denmark and the Climate and Clean Air Coalition (CCAC).

The new waste management model could consist of both a waste treatment plant for Cali and a source separation policy that formalizes informal waste pickers.  Since December 2011, CCAP has been working in Colombia to design a National Appropriate Mitigation Action (NAMA), and Cali is positioned to be the pilot city for implementation.

According to scoping and pre-feasibility studies done by CCAP in Colombia, the most feasible treatment technology for Cali is a Mechanical-Biological treatment (MBT) plant. This type of technology can be adapted to local conditions and can produce commodities such as recyclables, compost, and refuse-derived fuel (RdF).  Nevertheless, the implementation of this type of technology could be dependent on the receipt of international NAMA financing.

In addition, Ms. Mozo announced that Cali will be launching a pilot of their innovative source separation policy in two neighborhoods. If successful, this policy could be a global model to integrate informal waste pickers into municipal waste management policies.

The NAMA will allow for the diversion of municipal solid waste from the landfills, which are a significant source of methane emissions, in order to produce commodities such as compost and RDF. If the NAMA were implemented in similar cities in Colombia, the solid waste management sector would be carbon neutral.

CCAP is pleased to see Cali’s continued enthusiasm in improving solid waste management and will continue to support the design and implementation of policies in the solid waste sector that encourage GHG mitigation and have accompanying economic, social, and environmental benefits.


Since 1985, the Center for Clean Air Policy (CCAP) has been a recognized world leader in climate and air quality policy and is the only independent, nonprofit think tank working exclusively on those issues at the local, U.S. national and international levels. Headquartered in Washington, D.C., CCAP helps policymakers around the world develop, promote and implement innovative, market-based solutions to major climate, air quality and energy problems that balance both environmental and economic interests.
