Bio-en­zymes sprayed on Toledo land­fill

The Freeman - - NEWS - Ray­mond D. Abar­cas/KBQ

Toledo City En­vi­ron­ment and Nat­u­ral Re­sources (CENRO) has sprayed en­zymes on the land­fill in Barangay Put­ing­bato, an up­land vil­lage, to mit­i­gate the stench com­ing from the fa­cil­ity.

Five hun­dred mil­lime­ters of en­zymes were ini­tially sprayed on the garbage on Jan­uary 9, a day after CENRO re­ceived com­plaints from res­i­dents.

The bio-en­zymes come in pow­der form and have to be di­luted with non-chlo­ri­nated wa­ter be­fore it is sprayed on trash piles to speed up the de­com­po­si­tion process of garbage.

The en­zymes are used to ad­dress the foul smell from land­fills, waste wa­ter man­age­ment sys­tems, poul­try farms and pig­geries.

As for the long-term so­lu­tion to the leak and foul smell, en­gi­neer Pi­lar Canga, CENRO of­fi­cer-In-charge, said they are push­ing for the con­struc­tion of a P3mil­lion leachate pond at the land­fill.

Resid­ual wastes will un­dergo wa­ter treat­ment in a leachate pond where harm­ful chem­i­cals will be dis­solved.

Canga said they will bid out the pro­ject at the soon­est pos­si­ble time.

Among the re­quire­ments of a san­i­tary land­fill are lin­ing cover, daily soil cover, and leachate pond to avoid leachate leak­age.

The al­leged poor main­te­nance of the land­fill is caus­ing leachate to seep into ground, con­tam­i­nat­ing the ground­wa­ter re­sources.

More­over, Canga said the city needs five con­tain­ers to treat the wa­ter from the land­fill.

Canga said the city is ex­haust­ing all pos­si­ble mea­sure to ad­dress the stench and the de­te­ri­o­rat­ing con­di­tion of the land­fill.

“We are ex­ert­ing all ef­forts to ad­dress the is­sue,” he said, adding that the city con­ducted a con­sul­ta­tion with the af­fected res­i­dents.

Res­i­dents of Toledo in mid­west Cebu have been com­plain­ing of the san­i­tary land­fill in Barangay Put­ing­bato, re­sult­ing in smell, wa­ter con­tam­i­na­tion and skin ir­ri­ta­tion.

They said land­fill leachate is al­ready con­tam­i­nat­ing the wa­ter sources not only in Barangay Put­ing­bato but also in the neigh­bor­ing barangay of Can­lumam­pao.

Res­i­dents also com­plained that the con­tam­i­na­tion has caused skin dis­eases to some. —
