Hog raisers to use new technologies


BAGUIO CITY: The City Environment and Parks Management Office (CEPMO) through its Wastewater, Waters and Ambient Air Management Division (WAMD) is encouraging hog raisers in this city adopt alternative technologies to protect the city’s inland waterways.

One of the problems hounding the quality of the city’s waterways is the disposal of solid wastes in the city’s creeks. Some households along the waterways also connect their sewage lines to the waterways.

The wastewater that converges at the city’s waterways drains into the Balili River greatly affecting the quality of water.

In efforts to address the problems of water pollution, CEPMO head Cordelia Lacsamana said they are promoting, particularly to hog raisers in the city, to shift to vermi-composting and use portable biogas digester technologies to dispose of pig manure.

The CEPMO, with the help of the Baguio Vermi Growers, recently demonstrated how vermi-composting works to the first batch of hog raisers this year.

“The vermi-composting is a good method of composting waste especially pig manure to convert it to an organic fertilizer using worms. The earthworm called African nightcrawler or Eudrilus Euginia will eat the waste then it will produce a nutrient-rich soil,” said Baguio Vermi Growers President Moren Macay.

The voracious worm can also eat different wastes such as animal waste, sewage sludge, crop residues, industrial reuse, community waste and household refuse.

“Vermi-cast is the end product of the breakdown of organic matter and it is an excellent organic fertilizer and soil conditioner. Vermi-cast also builds nutrient-dense black soil which has a high content of good bacteria. It helps the plants grow in the garden with high vitality and nutritional content making it safer to consume,” he explained.

The CEPMO also gave the hog raisers a quarter kilo of African night crawlers to use for composting solid wastes and start vermicultures to increase the number of worms.

Biogas digesters, meanwhile, are equipment meant to store biodegradable materials to produce biogas.
