Resiklo (Recycle) is a 2007 Philippine post-apocalyptic science fiction movie. From Wikipedia:
Set in December 2021, Resiklo is the story of Crisval Sarmiento, an ex-military Colonel who leads a rag-tag group of survivors in the Philippines against the insect-like alien invaders known as the Balangs. Because of the enormous expenditures in resources during the invasion (hinted in the movie’s opening credits), the humans are forced to scavenge the destroyed landscape for anything that could be recycled and put to use at their secret sanctuary, called Paraiso (Paradise in English).
However, they are in a race against time, as in addition to the resource gathering, the survivors are fighting to eliminate the Balangs and their human collaborators, the Mutanos (mutated humans), while keeping Paraiso’s location secret and along the way, uncovering the truth behind the invasion as well.
