Parts in the production of cement


I can't give details on what all the bits here are, but I'd like to mention the fuel that runs this plant. Half of the energy needs of the furnace is met by coal and the other half is made up of a whole mishmash of stuff such as old tires, used solvents, plastics, dried sewage sludge from water treatment plants (remember the ARA post - link - from some time ago?) and, um, animal meal. According to Holcim, the plant uses state of the art technology to scrub the flue gases. One of the components of the filtering system is activated charcoal, which is then itself used as fuel.

Hmmm... burning tires? That doesn't sound that clean to me.

Check back tomorrow for a post on slugs. I'll dedicate it to you. ;-)

Burning Tyres actually reduces the NOx emissions of a cement kiln. The co-processing of waste at this kiln is a long and well established practice and they are world leaders in this field.
The co-processing of animal meal,in particular, has solved a waste management crisis after the Mad Cow scare.

I like the illusion of depth created by the perspective lines in this picture, and the color elements in the previous picture.

Thank you for your comment on my post, Z. To answer your question, Bahasa Indonesia has no native script. There are a number of scripts/alphabets for local languages like Javanese and Sundanese. And yes, they are still alive (although not used a lot in day to day life) and a subject of academic studies.

Welcome to the blog Egmont, and thank you for your input! It would be great if you could take the time to explain about tires and the NOx emissions, or provide a couple of links to sites where one could read up about it. Can you point to some publications available to the public about the waste management? Thanks!

I'm not sure that burning tyres is actually cleaner, but I do know my photography and that is a brilliant shot.

It's a great photo, and I learned something new by coming here today! Thank you!
