Depressing trip to the landfill

As part of my company's ISO-14001 team, we took a tour of the local landfill. If you've never been to a landfill, you need to go. It will inspire you to do way more recycling than you do now! Most of them will give you free tours, since they realize the importance of public education. In fact, take the whole family, and you'll see how quickly you can change their behavior!



On the downside, it was pretty depressing to see all the trucks constantly dump loads of waste all day long. One after another. The worst part is that many of the items being dumped could have been recycled (cardboard, wood, fabric, plastic bottles and jugs, paper, etc). But once it leaves the truck, it's against the law to grab the item (for safety reasons), so we saw piles of items that you wanted to go grab and place in the recycling bins, but we couldn't.



If I ran the landfill, I would require every truck to empty its contents, and sort out the recyclable items from the waste, before it ever goes up to the hill. Why do we expect the citizens to know all the rules? Why would they blindly allow people to dump items without any inspection or checks? With the constant updates in what can and cannot be recycled (which also seems to be unclear whomever I ask), educating the public will always be way too costly and too much "after the fact" to make any immediate impact. Spend that money and effort at the last line of defense, and use that information to flow back to the truck drivers and citizens with hard facts.

I realize there would be a lot of extra labor involved, but what about the cost of land for burying stuff we don't need to throw away, and having to buy more land a lot sooner, as a result of this lack of "inspection". If you consider any recyclable item that is dumped as an error or "escape", then common thought is that you go to the prior step and setup an inspection, until you eventually trace back to the source of the "error". Yes, public education is the ultimate scenario we should strive for, where no one throws away anything unless it cannot be recycled. In the meantime, you should manually sort out what doesn't belong until that time comes.

That brings me to the really depressing part. Once an item is dumped, it gets covered and all liquid is eventually extracted from underneath the trash. The hill is covered in a layer of material that prevents any moisture from entering. Basically, it's sealed up tight, and nothing gets in or out.



This is a problem because nothing will degrade or compost in those conditions. Biodegradable materials require water, heat and oxygen in order to break down, which they will not get inside the landfill (at least not enough before its covered forever).

BOTTOM LINE: Don't bother buying biodegradable materials unless you are going to compost them yourselves, or take them somewhere that will compost them for you (which is rare to find for most people)!

Here is some more information on biodegradable materials

P.S. This isn't a rant against my local landfill. They do use the methane to generate electricity, and the people there are passionate about recycling and reducing waste, and were just as upset about the situation as we were. I'm just ranting at the whole broken process...

Excellent comments and I agree everyone should tour their local landfill. I know what you mean about seeing all the stuff that should be reused or recycled. For your next tour, a visit to your local recycling center. They are usually collocated at the landfill and that’s where the stuff we put into our recycling bins is sorted. I think that one will be an eye opener for you also. You’ll find that most of what we put into our recycle bins will end up in a landfill. Recyclers are doing a great job of recycling those things that they can sell quickly and the stuff we think is useful usually isn’t something recyclers want.
There is a better alternative to the “Dry Tomb” landfill you visited and it is called a “Bioreactor” landfill. The bioreactor landfill is designed to enhance biodegradation and capture the landfill gases which are used to produce clean energy. After numerous visits to landfills and recycling centers we have decided to be more active in promoting the development of these new landfills.
By-the-way, biodegradation does take place in a dry tomb landfill but at a much slower rate. Most of the gases produced in the anaerobic environment of a dry tomb landfill are methane. Methane is a green house gas but if captured it can be used to make electricity. Much of the methane in dry tomb landfills escapes into the atmosphere where it contributes to global warming.
Thank you for taking the time to share your thought and ideas….if more of us start doing what you are, we might have a chance.
