What are the components of Hazardous Wastes Paradigm? Define and explain the regulatory requirements for each component.
Waste Generators - All waste generators shall provide the government the information on the type and quantity of waste generated, produced or transported outside Hazardous Waste Storage and Labeling - Vessels, containers, and tanks for the storage of hazardous waste shall be clearly labeled according to class or classes, subcategory, waste number, name and address of generator, and maximum capacity of volume Treatment and Disposal - No waste shall accept, treat recycle, reprocess, or dispose of hazardous wastes unless done in the premises as prescribed and permitted by the government Import and Export - Any person who wishes to import into the Philippines or export hazardous substances must seek and obtain prior written approval from the government
