Better think twiceJust recently, a bill that seeks to promote the use of waste-to-energy (WTE) technologies has advanced in the Senate after it was reported out for plenary approval. The bill noted that population increase has driven up the volume of solid waste. Tulfo noted that currently, sanitary landfills are the primary long-term method of solid waste disposal under Republic Act 9003 or the Ecological Solid Waste Management Act. In Thailand, the closest comparison with the Philippines, the cost of waste management is $30 per ton. The DENR earlier said solid waste management remains a major problem for the country mostly due to mismanagement of waste segregation at the local level.
