Article 2 Section 21 of Republic Act No. 9003 otherwise known as Ecological Solid Waste Management Act of 2000 provides the Mandatory segregation of Solid Waste to be primarily conducted at the source which includes residential, institutional, industrial, commercial, and agricultural sources.
Segregation at the source is easier than segregating big bulks of wastes from a whole community. Since the people in the community, households themselves are segregating the wastes, it encourages recycling as they can see what wastes are reusable or recyclable. Proper segregation also helps keep the environment clean, reduces pollution. But these efforts are useless if the wastes are not kept segregated upon collection.
Our city (Bayawan City) in Negros Oriental is very strict with the implementation of this RA. During garbage collection per barangay, if the wastes are not properly segregated, the household may either be fined or their wastes will not be collected. The city also has a landfill which has been used by other cities as a benchmark. Schools and students are strongly encouraged to recycle and they make sure that the students, faculty, and staff are very familiar with the waste management guidelines. Before the pandemic, they would also have field trips to the landfill.
