Filtering toxic fumes from burnt plastic

NO!

The "P" in HEPA stands for particulate. They're good for dust and pollen; they are not intended for fumes, particularly poisonous ones.

You need a Scott Air-Pak (or equivalent) plus eye protection. You also need the advice of an industrial toxicologist if you are burning plastic.

I planning to built my own air scrubber for this purpose. I think the hepa filter is effective but more costly.

No, the HEPA filter is not effective. If you are even remotely considering this, at least ask a fireman what they use to go into fires where there are plastics. read about airplane fires. Go to the OSHA website. But, don't breathe that crap, please?

I suggest a Donaldson Scrubber. View these products at: www.donaldson.com

Engineering will fit your application.

Now I'm confused. Are you planning to incinerate plastics in something like an industrial furnace or in a cogen plant? If so, you need to talk to some industrial pollution guys; a HEPA filter is OK for an after-filter following a baghouse, but I can't imagine using one as a primary. And, no filter, no precipitator comes close to touching dioxins. The generally correct solutions for plastics are:

minimize use;

recycle when economical;

compact and put in leach-free landfill;

incinerate with a controlled burn and a very high chimney, following the basic rules: NIMBY and BANANA.

Many thanks for the inputs..

What I am really trying to do is to cut open a plastic material with the use of a hot rod and not mech'l tools of sorts to avoid vibration. I assumed that the process and the byproducts(fumes) are the same as incinerating plastics. Am I correct?

Again,, many thanks.

No. When you incinerate, there's a chimney way up there that disperses the fumes. You really have to look at the type of plastic (those with Cl are real nasty) and the applicable laws (are you exposing workers, the general public?). Some of the fumes from burning plastic are toxic.

DON'T BURN PLASTICES RECYCLE.

Hi

I want to melt plastic in canola oil ( like potato fries) and mold the stuff into different things. Does melted plastic releases any fumes? Does the melting stage release as much fumes as burnt plastic?

Thanks

Hi

No one has replied to above memo for one month! Am I doing or saying anything wrong?
