The Mines and Geosciences Bureau (MGB) -7 together with hundreds of volunteers in the region participated in the 2021 International Coastal Cleanup simultaneously done on September 18, 2021.
The activity was spearheaded by the Environmental Management Bureau (EMB) -7 in partnership with Barangay Subangdaku in cleaning some portions of Mahiga Creek (near Innodata) in Mandaue City.

Trash items collected were mostly beverage and water bottles, beverage cans, sachets, pouches, cups and plates (foam, papers & plastics), plastic utensils, plastic food containers (bleach and oil), etc. There were also damaged appliances, toys, footwears and clothings.
As community volunteers removed the trash from the heavily silted creek, five MGB7 participants helped in identifying the trash and debris collected and recorded it on the standard data form.
In cleanup summary, MGB7 alone have recorded about 135 cu. ft. of trash approximate weight 3,000-4,000 kilos at 30 sq. m.
The International Coastal Clean-up (ICC) is celebrated yearly by virtue of Proclamation No. 470, s. 2003, observed every third Saturday of September. (MGB7 IO)
