The Department of Environment and Natural Resources is urging households to segregate waste to help the country meet its greenhouse gas emission reduction target under the Paris Agreement on climate change.
Practicing segregation will enable households to recover waste for composting, DENR Climate Change Information and Technical Support Division chief Albert Magalang said.
Composting is an age-old method of making fertilizer using decomposed organic matter. Among the compostable waste are fruit and vegetable peelings, leftover food, and fish and animal entrails, according to the National Solid Waste Management Commission.
Experts said composting puts such waste to good use and significantly reduces the methane emission of decomposing organic matter.
Methane is among the greenhouse gases that are increasingly accumulating in the atmosphere, making global temperatures rise and changing the climate.
