Deputy Minister of Environment Says 43 Landfills Are Burned, Encourages Waste Sorting from Home

"PSEL without sorting, the waste will become very wet, mixed, the water content will be very high, namely 60-70%, whereas effective PSEL requires waste with a water content below 30%," he said.

This figure is Diaz's explanation in his speech. The KLH/Environmental Management Agency (BPLH) statement does not yet specify the type of PSEL technology or the technical basis for the water content limits in question.

The main message conveyed by Diaz was the need to link sorting at the source with downstream processing. Waste management technology needs to go hand in hand with changes in people's habits in handling the waste they produce.
