why cant we burn rubbish fromland fill sites?

Question

after recycling ,
why cant the rubbish be made into brickets and used as a
fuel in power stations

Answer 1

I would think that there would still be come communities that still do that. Just a few years ago, Nashville Tennessee shut down their trash incinerator that was located right downtown. It burned waste that would have gone to the landfill and used that to generate steam and chilled water for the buildings downtown. Environmentalists didn't want it anymore due to pollution but I'm pretty sure that the primary reason to remove was aesthetics and land value. They removed it and replaced it with a lot smaller (in size, not capacity) gas turbine generator.
As far as pollution, incinerators such as these are not like throwing plastic on a back yard fire. Yes, pollutants are released, but the temperature and control of the inceneration reduce them significantly. Since natural gas and other sources will now be providing the heat and cooling for these buildings, the CO2 produced per unit of heating or cooling will still be relatively high. Factor in the extra landfill space required and the CO2 and methane that will be released from the landfill as the trash decays and I would bet that there will be just as much if not more greenhouse gases produced now.
BTW, any additional power produced that didn't get used for heating or cooling was sold back to the local utility.
I'm not advocating for this type of power. But, simply saying that it expels pollution and should be eliminated doesn't look at the whole equation of what it takes to make an informed decision. Remember, almost 70% of all power generation in America makes some type of air pollution.

Answer 2

Suck it up. in the event that they have a enable there is not any longer something you're able to do. I propose what the hell else are they gonna do with their a million/2 burned rubbish? in the event that they don't have a enable.... nicely, call the hearth branch and say "My friends are burning rubbish, have they have been given a enable or could desire to you come lower back over and placed it out?" in spite of this all fires stink to some quantity ... and stink for sooner or later is extra suited than smelly rubbish constantly. yet there is likewise a element observed as tolerance it is anticipated whilst residing close to others.i.e. in case you do unlike your friends; flow. And be optimistic that there is not any longer something which you and your loved ones does that annoys them as a results of fact in any different case there is guaranteed to be retaliation. constantly bear in mind "fences make for sturdy friends"

Answer 3

Because the process of combustion causes volatile/reactive compounds to be freed from their otherwise stable structures. These compounds are then able to react with the objects in the environment. And in enough cases, that is a problem.

For example, the sulphur compounds used in tires as a part of the vulcanization process are freed when the tires are burned. These compounds float up and combine with the water in clouds to form acid rain.

Other compounds pose a direct threat to us when they are inhaled.

No amount of "scrubbing" can be certain of removing all of these compounds from the air as the rubbish is burned.

Answer 4

The stuff needs to be processed into basic materials first and then a lot of it can be used for energy. There are elements in trash that have value other than for energy use. Plastic of all kinds can be processed into oil that can be stored and would reduce the amount of CO2 being added to the atmosphere. All of stuff can be reduced to raw material rather than letting it rot in landfill and poluting the environment. Its just a matter of good engineering and managment.

Answer 5

I fugure that some day after the oil runs out and the trees are all cut down for fuel, future people will be excavating our land fills for the energy! All our old tires, paper garbage, all that. It will be valuable to own that land just like oiil wells land is today!

Answer 6

Basic answer = ECONOMICS

To generate electricity or useful heat, you have to invest a lot of money in a good burner and heat exchangers. To make it work, you need a consistent fuel or feedstock. The contents of landfills are highly variable and require expensive processing to create a reliable, useful (high-energy) fuel.

Answer 7

some of the stuff on landfills, was dumped illegally.
the mix of materials if burnt are potentially explosive or would give off seriously lethal gases.

many old landfills give off methane

Answer 8

Ermmm

Because it is filled with materials that are poisonous when burned.

Answer 9

mostly because they would release a crap load of toxins and green house gases into the atmosphere. It wouldn't be pretty.

Answer 10

Ummm... Air pollution?
