Our history


  • First initiatives

Citizen initiatives emerge in response to the closure of the Doña Juana landfill in the city of Bogotá, D. C., Colombia. These initiatives led to campaigns such as "Desembólsate (un-bag yourself) to promote the rational use of bags", "Return to the basket", and "Put your shoulder in the rubble".


  • Inception of the first project

The "Zero Waste Municipalities" project was developed. This initiative focused on comprehensive organic waste management in the eastern province of the department of Boyacá, Colombia, with a territorial approach.


  • Formation of a transdisciplinary team

A team from various disciplines was formed to promote the Zero Waste model in Bogotá, Colombia.


  • Emergence of organized civil society

The "Zero Waste Bogotá Citizen Collective" was established. This civil society group, composed of various actors, sought sustainable solutions in comprehensive solid waste management and applied circular economy.


  • Establishment of Bogotá Zero Waste

A Non-Governmental Organization was established with a focus on the development of socio-environmental projects in cities.


  • Expansion of scope

Due to the successful implementation of the model in major cities of Colombia, the organization transitioned to Zero Waste Colombia, thereby expanding its reach within the country.


  • Research and innovation

The process of researching and modeling Zero Waste Management Systems for local and corporate governments began, establishing itself as a national standard with global impact.


  • Certification

The Certification in Zero Waste Management Systems was launched in collaboration with the standardization and certification body, ICONTEC.


  • Transition to Global Zero Waste

Considering Colombia's advancements as a leading country in the Circular Economy and waste management in Latin America and the Caribbean, the organization expanded its service lines at a regional level.


  • Global Zero Waste Standard

Given the global impact of the organization's lines of action, the Global Standard Zero Waste was established as an international tool for the Circular Economy and Zero Waste.


  • Voluntary Programme on Circular Economy

The Voluntary Programme on Circular Economy was consolidated for the management of the flow of materials with a plastic recycling methodology."
