Can cardboard boxes be put out for pickup or do they need broken down and put in bags?

Great information. Thanks

Non ferrous metals are separated out of the bottom ash(what's left after it's burned) with an eddy current separator. An eddy current separator induces a magnetic field in otherwise non magnetic metals and flings them out. It's an interesting machine. There are videos on youtube.

Glass and the rest end up getting buried in landfills. That said, the amount of waste is significantly reduced from what came in the door. What remains is about 5% of what came in.

Actually, in the Covanta plant all materials go into the combustion chamber. And, the amount that is left is about 10% of the original amount.

not the Covanta plant we are using but similar operation ->

It' my understanding that cardboard boxes should be flattened but need not be placed in bags. Also, cardboard can be placed out for pickup on any of your trash pickup days.

So they pull the ferrous metals out after burning, then run it again over an eddy current separator to get the aluminum/copper. The guy in the tour video mentioned it's 10% of the original volume after burning. Then they pull out the metals. So it's less than 10% bottom ash that goes to the land fill. Like 5% .

Remember, we are talking about volume not weight so I believe 10% is the closest volume figure.

I can ask again although I believe my figure is what I have heard in the past.

Could you also ask if they run tours when able....sounds like an interesting process to see

And based on the video metals are recycled to some leve.

The NSCUDD board has not been able to tour this plant because of Covid-19 restrictions. Last summer, the board did tour a larger Covanta WTE plant near Tampa.

Once things return to a near normal, both the Covanta WTE plant and our NSCUDD water treatments plants would both be informative/interesting for Villagers to tour.

I toured a Covanta plant in Massachusetts. I should have had an environmental resperator on. Had some breathing issues for weeks after the visit.

The plant are always smelled like a garbage dump in about a five miles radius.

If you tour get a respirator.

Also in Massachusetts lower power rates were advertised and actually occurred with lower collection costs.

Here we seemed to get higher collection cost and no power reduction costs. Lousy political negotiations probably are a result.

Good luck if you might live near it. You'll need it.

What happens to aluminum cans after the burn?

The Covanta plant representative says that aluminum is collected/processed and sold. He claims that this operation is efficient. However, everything that I am told about the Covanta operation is always positive. I hope that my many questions asked at board meetings about Covanta have been honestly answered.

My have metal separators, Thin aluminum will burn.

How many power companies were involved?

Thank You

I believe the bottom line is to get the most btu’s from a ton of trash and not to get the biggest reduction in trash volume going to landfill. Energy, or heat if you prefer, is used to produce power not to reduce hard to burn material. IMHO

Thank you for providing a link to the handout. Easy to read and to share.
