METRO QUEZON CITY MANILA MALABON CITY 14°40'N Manila 14°40'N NAVOTAS（Population：12million (2014)) Bay KALOOKAN CITY • Philippine government, with the PRRC as a prime initiator, has implemented a variety of initiatives over Clusters 1 , 7, 8, 9 MARIKINA CITY Laguna the past more than 15 years, but drastic improvements have not yet been achieved.

Hi-Beads • Purification by mineral will create an environment, in which microorganisms decompose and circulate organic matter which can be further utilized by animals and plants. • Reduction of the deposition amount of the organic mud and hydrophilic improvement can be expected by the progress of the weight loss and separation of organic matter through purification. （Source：Brochure of Chugoku Electric Power Co., Ltd.)
