Garbage!

Good thing they didn't have any candy yet!

It would be nice to say that Karen and I had such great success with the first field trip to the beach that we decided to go on another field trip. But, that would be a lie. The truth is we planned for two!

Kids happy to be barefoot again

hahahahaha… With the help of a JICA volunteer, Yasuko, we managed to bring thirteen children and two teachers from each of our schools to the Tafaigata Landfill. Going to the landfill may sound like a stinky,

unpleasant place to go to for a field trip – and it was – but the kids learned about waste management, recycling, and water treatment. Living on a 430 square mile bit of land, 131.5 times smaller than the

activity where the students learned how long it takes for things we throw away to decay into the ground. Do you know how long it takes a plastic bottle to decay? Not in your lifetime, or your kids, or their kids. Decay STARTS around 1,000 years… enough said. The kids were shocked and intrigued at the same time. At the end of the presentation, we took a ride to the actual landfill to see the gas vents and all manner of disgust that lived there. For all you landfill nerds out there (Karen’s mother in particular), both landfills in Samoa are very high tech. They use the Fukuoka Method. This method, developed by the Japanese, allows airflow underneath the landfill and into the garbage. Because of the airflow, bacteria are able to digest aerobically, producing carbon dioxide as a waste product rather than methane. A short walk brought us to the leachate pond. They were very happy with how well it works and were doubly proud to announce that they have found no traces of heavy metals such as mercury in it… yet. The leachate pond is simply a place where the runoff from the landfill goes to. Nothing sinister, like the sludge pond. A sludge pond works something like this. A truck backs up to the concrete ramp, opens a valve, and out comes the, you guessed it, shit. To insinuate that these trucks only drop off human shit would be an exaggeration. Their deposits also contain urine, vomit, decaying toilet paper, the islands’ manufacturing waste liquids, and anything else that ends up flushed down the toilet like your dead pet fish. The result looks like this. I am sad to say that due to current technological constraints, you cannot share in the repugnance which we endured. From there, we visited a medical incinerator, which is little more than a giant furnace in a small shack and then it was off to the recycling center. The kids especially loved the industrial-sized digital scale. Everyone weighed themselves, then a few at a time and then all together. We learned that you could call the recycling yard to come and pick up your recycling – but they charge you to come and get it. So remind me why no one on the island has ever heard of recycling? Lunch was provided after a quick review and wrap up. Then it was back to our neck of the woods. In the end, I like to let the children decide whether the trip was worth it or not. This is what they had to say. Field trip two complete for both schools, bringing us up to three total. We will post soon about Karen’s fourth trip to the National Energy Awareness Day and spelling bee.

    High Tech? Ummm? Your explanation is mystifying. I see no evidence of either primary or tertiary treatment.

    This looks very fourth world.

      Looks can be deceiving and pictures are not always representative.

      According to a presentation available on the SPREP website, semi-aerobic landfills like the Tafaigata Landfill are excellent solution to the problem of waste disposal in SIDS in the Pacific and in other developing countries. These landfills have three main advantages: first, generation of methane (a powerful greenhouse gas) is minimized; second, leachate is removed more quickly from the landfill for treatment; and third, because decomposition within the landfill occurs more quickly, the landfill is more stable and requires less maintenance.

      The leachate collected from the landfill is allowed to leave quickly, decreasing the moisture present in the landfill, decreasing pressure on the landfill liner, and allowing aerobic decomposition to continue. The leachate is then treated through a series of natural treatment filters (which we did not take good pictures of).

      Advantages for this type of landfill in developing countries are that local materials can be used in construction (inexpensive, but effective); decomposition is quick and creates fewer emissions, leachate treatment is easier because it is less contaminated, and existing dumpsites can be rehabilitated to sanitary landfills (as was the case with Tafaigata), and they are sustainable (in terms of cost and extending the lifetime of the landfill). In addition, since decomposition occurs more quickly and less methane is produced, less monitoring of the landfill site is needed after the site is closed (unlike traditional landfills which need to be monitored for methane gas leakage for many years after closure).

      The Fukuoka method has been used in Japan since the 1970s and is a recommended method of waste disposal within the country (although the Japanese have largely switched to incineration because of space constraints).
