World Clean and Green Week – September 17-23, 2025

World Clean and Green Week, observed from September 17 to 23 every year, is an initiative developed in the Philippines as part of the global effort to reduce waste and avoid environmental pollution. Throughout modern history, global cleanup efforts have been a thing, particularly after such disasters as earthquakes, floods, and hurricanes. These efforts are typically executed by the affected communities and assisted by various international organizations, including relief organizations and N.G.O.s. These efforts have included removing land mines, cleaning up beaches, and doing other non-government cleanup efforts toward creating a better environment.

History of World Clean and Green Week

Throughout most of our history, the volume of waste that humans generated was inconsequential as a result of low population density and the fact that most of that waste was mainly ashes and human biodegradable waste, which were locally released back to the ground with minimal impact on the environment. Some civilizations even had other ways of managing their waste; for instance, the Maya of Central America had a fixed monthly ritual of gathering together and burning waste in large dumps.

The onset of industrialization and increase in population resulted in a buildup of waste in the cities, causing a decline in sanitation and the general quality of life, especially in urban areas. The lack of waste management regulations then gave room for streets to become choked with filth. The earliest civilization in modern history to proffer a solution to waste management was the British Empire, where, in 1751, calls were made by Corbyn Morris for the establishment of a municipal authority that had waste-removal responsibilities.

Sadly, a solution would not be reached until the middle of the 19th Century following the devastating outbreak of diseases such as cholera. In the 1842 report titled “The Sanitary Condition of the Laboring Population,” social reformer Edwin Chadwick argued for the importance of an adequate and sufficient waste management system to improve the health of the population.
