Waste (RDF, PRDF, garbage) to energy is equally popular at the local level, killing two birds with one stone, disposing of unwanted garbage and generated desired electricity.

I agree with you. There is a need of organizing events to concern people about recycling. People should be rewarded for their recycling tasks to encourage others.

Hi

Yes in one way Shredding machine is good to shred the tires and to use it to add carbon in furnace ,we are using it just to get rid of tires but in other way there is chance of generating more toxic gas to use it,

Best way to convert it to granular form to use in Electric arc furnaces

The irony is that what appears to be very logical, waste to energy (which is otherwise waste to landfill or waste to incineration), is never economically feasible and always requires government subsidy in order to proceed. We have supplied high angle conveyors to such a project in Florida, USA, but have made proposals to many others, some of larger scale. These projects did not proceed because they could not get the subsidies. Why are the subsidies needed when the benefit seems so clear? The material must be collected and transported in any case. In the case of incineration it is merely a matter of exhausting the energy or directing it to a turbine powered generator. Does any one have a laymen's break down of this economic comparison that never seems to favor the waste to energy?

I think waste recycling has to have a profit in it somewhere for anyone to be interested. Here in our State, we have mandatory recycling of almost everything, and recyclers who will pay a pittance to take your materials if they are of value, washed and declared ready to reuse/melt, etc. Stuff like paint, steel, tires, milk jugs, cans of beverages. The list goes on and on.

But the way it was started was the state made a declaration to recycle-period. And someone answered, in our case, we have to pay a measureable amount, less than $10 per month for a household of normal inhabitants (perhaps).

We separate all recycleables and put them in a supplied bin and follow their listings, non-recycleables go into another bin like garbage, foodstuffs, dirty stuff, etc. Then in the third bin goes the glass, clear in one, colored in another.

If you have paint, batteries, hazardous anything you deliver to their establishment they will take it at no charge and put all the paint together and resell a funny color in bulk for peanuts, mainly to contractors for subcoats. batteries are sent to recyclers for the ingrediants, perhaps offshore to India or China where labor is cheap with no EPA controls or standards and no concerns for labor health. I think Africa is next. Labor in south America is becoming too educated.

Electronic recycling is the thing of the present. Companies all over are popping up to do the same as the batteries. Lots of gold, silver and wafers out there.

Tires-now that's a item that started out with a king or something on a desert island in the pacific put in a power plant to use shredded tires as fuel. Then he put out an ad to collect the tires and wanted them shredded all for free. Got bit on that one too. Heard that the power plant has no fuel, as shipping costs alone outweighed the free sign. People at least today are not throwing many of them in the ponds or sides of roads anymore, as at least in our state there is an attempt to shred them and use them as additives in asphalt for roads and airport runways as they make a softer but more resilient materials. I don't know how they remove the SS beading wire as it is not magnetic. It's still on trial but seems to be an answer. I would hope in India, where asphault is scarce this could be a benefit in sideroads. In major highways I think they should stick with cement, if they ever learn to use a decent mix.

I wouldn't use tires in steel making, as the stainless beads will screw up the chemistry and the sulfur will end up making crappy steel and a smelly neighborhood. Been there done that. ■

Tcinc,

Thank you for sharing your broad knowledge on recycling. I remember that many years ago, in the 1960's junk yards were happy to pay for rags, cardboard, newspapers and metals. Brass and copper paid very well. All of these were recycled. The bottle companies would pay $0.02 for each small glass bottle (12oz) and $0.05 for each large glass bottle (1/4 gal). Recycling and processing of waste has deceased not increased.

In any case, focusing on waste to energy vs waste to landfill or to incineration, does anyone have a layman's economic summary that explains why waste to energy projects are never economically justified and always dependent on goverment subsidies.
