Comments on: Getting gas from trash

A Boston-area entrepreneur imagines how to develop a business based on large-scale repurposing of organic waste.

This is good but....

I rather the Delorean that can move through time

if you would

Pick me up a Mr. Fusion next time you visit the future.

San Francisco

Actually, on ABC Evening News this week they had a story on how this is already being done in SF. There is a pilot program that's been successful enough that they are expanding it. They collect scrap trash from restaurants and doggy poop now. There was big thing about how much doggy poop there is in the city and this was a good use for it.

The next step is to collect waste using methane powered vehicles

I can imagine a time when thermophilic digesters replace almost every landfill.

Mining landfills

Think about how much recoverable material is already buried in landfills and realize that the day is approaching when existing landfills will be mined for the resources they contain. Seperating out the still preserved organic matter and "digesting" it for energy will be only one part of that process.

I can't see why the methane gas in existing

sources isn't used. Just go to your nearest sewer vent pipe and fill-er-up. A pump on the methane powered vehicle woul suck out the sewwer gas and away you'd go. I can invision thousands of public vent pipes all over the urban cities. ;)

Metnane Gas Use

Methane gas is simply a by product of organic degeneration. As stated, the problem of large accumulation of "raw" materials is a major problem.

As land fills have grown, operators have been forced to vent them, lest they explode.

Ideas advance mankind, let their ideas roll.

Methane Gas

I had an idea for extracting methane from waste.
Why not create specific containers that the waste is put into. These could then be stacked and managed.
Maybe the containers could be the size of a rubbish collection truck. So, in the morning the truck would pick up a container. Do its rounds and then at the end of the day drop off the container. No mess, no fuss and everything managed.

Once they drop below a certain level of production you can empty them, recover what is valid and potentially process again in a more efficient way.
By having fixed sized containers the issue of tapping off and space becomes less acute.
The methane would be tapped from the same point in the container allowing easy collection and potentially fed directly into a generator for electricity.
Overall space requirements are reduced as when containers are redundant they can be removed and replaced without affecting the overall stack.

Once the waste has been composted it will take up less space and so reduce the storage requirements.

The only issues are:
Defining the standard and getting it used ? need municipal collections to support it.
Set up costs for containers and infrastructure at composting site.

So, other than millions and a change of world order I think this would be a winner?

Methane

Sixty years ago waste treatment plants captured the methane and used it as fuel for engines that powered pumps and could even generate eletricty. I suspect that few do this now. A local landfill that was closed was piped to a pair of generators for several years. The pipe is stil there and possibly the engines. Outside exhaust pipes have been removed. Probable cause is that volume of available fuel gas is now too low to even idle the plant. Any setup like this would be labor intensive. That spells as really big costs for seven days times three shifts.

This county burns two train loads of waste at an upcounty power station. Energy is sold from the conversion.

If there is a profit I would be surprised. Dumping costs are nearly a hundred bucks a ton. At the dump is was around twenty. Progress isn't cheap. More energey is extracted by incenderation than if it were fermented into methane, less mass after the burning than if made into methane. A lot of the costs is from disposal of ashes.
