San Jose - Tarlac Province


San Jose, Tarlac Province, has a network of cool streams flowing from the western mountains, it one of the few places in the Philippines that it is still safe to drink water directly from the river. Many small villages can be found near and along the water ways.

Until recently the people in San Jose had lived in near perfect harmony with their environment; sadly things have recently changed. Along my short 3km hike to the river, I estimate I encountered about twenty small dumping sites composed mainly of baby diapers. All of these sites were relatively new. Each site had about 20-100 diapers.

Garbage Dynamics

Garbage accumulates at different rates depending on what type it is and where it was dumped. Often it starts out as a few pieces of discarded plastic, once a place no longer is pristine, people are more likely to litter more. Once some threshold has been reached, someone will dump the first big bag of trash, this quickly leads others to dump more in the same area. There is a powerful feedback effect.

It is routine in the Philippines to burn trash in remote areas, this helps restore the areas to a relatively clean state, and control the feedback effect. Diapers are hard to burn compared to most other trash, so they tend to build up and encourage the growth of dumping sites. The Pinoy style for trash burning is simply to throw some grass on top and set it ablaze. This technique fails with diapers.

How To Safely Burn Plastics

Grass and wood should be placed under the plastic. A ratio of at least 50/50 wood/plastic is the minimum. Less harmful dioxins are released when the fire is hot, so the more dry wood the better.

Anything thing with chlorine (like paper products) when burned with plastics creates more dioxins, so burn them separately. Avoid burning black and dark colored plastics. Obviously, try to recycle as much of the plastic as possible, instead of burning it.
