The Environmental Barnstar

 * Now I realize that the barnstar you gave me (The working man's barnstar) can be subsituted by the Environmental Barnstar since it's more specific and towards environment. Mind if you make that switch?  OhanaUnited   23:18, 29 April 2007 (UTC)
 * Hi Ohana, the barnstar was awarded for all the categorisation work for the different environment articles you processed. I thought this was the relevant barnstar to be awarded. Feel free to change it if you like. --Alex 07:42, 30 April 2007 (UTC)

Portal review
Hey Alex, after a few days of hard work, I managed to get Portal:Environment into decent shape. Would you like to give a portal peer review on this portal? OhanaUnited   Talk page   15:44, 26 June 2007 (UTC)


 * You mean the ones in Environmental technology? I will add that in. But right now my main concern is the selected biographies section because biographies needs to be expanded. Three individuals don't seem to be enough in that section. Do you know any well known environmentalist?


 * Side note, I got accepted in University of Toronto's co-op program in environmental science biology stream. It's time to work in the field, working with real environmentalists, as opposed to sitting in boring lectures listening to what the profs say.  OhanaUnited    Talk page   15:57, 26 June 2007 (UTC)

India & Waste Management
In our country, the concept of Solid Waste Management originally started after 1994. It was due to pnumonic plague in Surat and a litigation filed by an activist that people and government started thinking about managing waste. Earlier it was only sanitation. Our organization initiated waste management operations in 1996 and now catering to almost 30 million population. It is Centre for Development communication and has spread in 9 states of India.

waste-to-energy <-> incineration
Hi Alex,

I saw that you merged the two articles on wte and incineration. Splendid idea!

But you still seem to treat the two terms differently. Is that how the words are used in the UK? A am working professionally with incineration plants in Scandinavia, and they certainly does not fit into the description in the article - they would all be waste-to-energy plants. We definitely use the two terms interchangably, the latter most often when addressing people with little prior knowledge on what it is.

Do you percieve any difference?

Claus


 * Hi Claus,

Thanks for the comments. My aim is to separate what the industry terms waste-to-energy plants and energy-from-waste plants, which generally means incineration. Perhaps this indicates a degree of linguistic detoxification against the stigma associated with old incineration facilities. Literally energy from waste includes anaerobic digestion, gasification & pyrolysis amongst other technologies. I have aimed for the advanced WtE facilities to be covered and differentiated in the main incineration article. The waste to energy article therefor covers all forms of waste to energy and not simply the terms that advanced incineration facilities have encompassed. Hope this explains the logic.

Alex

Can any non-member of the WikiProject Environment project post a WikiProject Environment template on an article Talk page and also assess the article?
To be specific, anonymous user Jbntj, who is not listed as a member of the project, posted a WikiProject Environment template of the Talk page of Fossil fuel power plant some time ago and also assessed it as a Stub Class. Is that proper? I cannot imagine anyone considering Fossil fuel power plant to be a Stub Class. It is a very large article with 16 sections, numerous diagrams, photos and references.

I might add that anonymous user Jbntj also added a WikiProject Climate Change template to Fossil fuel power plant, altho he is also not listed as a participant in that project.

And recently, he added a Cleanup tag to Fossil fuel power plant and refuses to explain why on the Talk page of that article other than to say the article is "dirty".

A very careful reading of the "Contributions" page of anonymous user Jbntj discloses that he has done this sort of thing on many energy related articles. In my opinion, he is very biased against use of coal or oil because he feels they bear a major responsibility for global warming. Wikipedia has dozens of articles devoted to global warming and climate change where anyone can contribute content or discuss their feelings about coal and oil. However, I don't believe posting WikiProject templates on technical articles about the use of coal and oil is a proper method of trying to promote biased opinions against such articles. Fossil fuel power plants are a fact of life and Wikipedians have every right to create and to contribute NPOV content to technical articles explaining how coal and oil fired power plants are designed and used.

I will be very interested to learn what members of this WikiProject Environment have to say about my above comments. Alex, please reply at Wikipedia talk:WikiProject Environment. - mbeychok 01:51, 6 August 2007 (UTC)

Scope of WikiProject Environment
Do you think the scope needs to be changed as per Wikipedia talk:WikiProject Environment  OhanaUnited    Talk page   12:39, 6 August 2007 (UTC)

Take a look at what Ghetsmith has done to the Talk page of Fossil fuel power plant
He reverted OhanaUnited's very recent change from Class:Stub to Class:B for the WikiProject Environment template. It is now back to Class:Stub.

He also replaced the WikiProject Climate Change template which OhanaUnited had very recently deleted.

He then archived selected portions of the Talk page comments so that it now contains mostly just discussions of the environmental aspects.

It seems that some user (or some group of users) is bent on turning the Fossil fuel power plant into propaganda about the environmental and global warming evils attributable to power plants. I find it difficult to believe that it is just coincidental that users Jbntj and Ghetsmith happened to come along at about the same time.

Take a look at Ghetsmith's Talk page. Is there anything that can be done to stop this behavior? - mbeychok 05:34, 7 August 2007 (UTC)


 * Hi Mbeychok, just looking at the article the logic for assessing the article as b for energy and stub for environment could be due to the fact there is not a huge amount of information regarding the environment in the main article. I was under the understanding however the rating scale was for the article on the whole, although I confess I am not fully up to speed with the rating proceedure. I would think their edits should be followed. If you believe they are sock puppets for one user and you have some proof it should be reported to an adminitrator to take up. Hope this helps --Alex 07:47, 7 August 2007 (UTC)

Some thoughts about the article Anaerobic digestion
Alex, in response to your request, I have very briefly scanned the Anaerobic digestion article and it appears to be well-written, very thorough and very well formatted.

The major thing that caught my attention is that there was no definition of what is meant by the word "anaerobic" and no mention of the fact that aerobic processes utilize free gaseous oxygen (or air) whereas anaerobic processes do not use free gasous oxygen (or air). In other words, anaerobic process occur in an oxygen free environment. Here are two paragraphs from my book Aqueous Wastes from Petroleum and Petrochemical Plants published by John Wiley in 1967:

''In an aerobic system using free gaseous oxygen (or air), the end products are primarily CO2 and H2O which are the stable or oxidized forms of carbon and hydrogen. If the organic waste contains nitrogen, phosphorus and sulfur, then the end products may also include NO3−, PO4−−−, and SO4−−.''

''In an anaerobic system, there is an absence of free gaseous oxygen. The oxygen source may be the organic waste itself or it may be supplied by inorganic oxides (in the waste). When the oxygen source in an anaerobic system is derived from the organic waste itself, then the 'intermediate' end products are (primarily) organic alcohols, aldehydes, and acids plus CO2. In the presence of specialized methane bacteria or microbes, the intermediates are converted to the 'final' end products of CH4 and more CO2.''

I suggest that the Anaerobic digestion article include a paragraph or two similar to the above paragraphs. Obviously, my two paragraphs would have to be modified to match the wording used in the article and to mention that sulfur in the waste would be converted into hydrogen sulfide (rather than sulfates as in an aerobic process).

Also, in the section "Biogas refinement", there is this statement: If they are high, levels of hydrogen sulphide may need to be altered due to the toxic nature of the gas. In my opinion, that sentence is too weak. There is no question but that hydrogen sulfide must be removed. In the USA, our national government's environmental protection agency U.S. EPA has mandated that industrial facilities may not burn any fuel gas that contains more than 160 ppm by volume (0.016 percent by volume) of hydrogen sulfide. The air quality regulatory agency in Southern California (the SCAQMD) has gone even further and mandated that fuel gas contain no more that 40 ppm by volume (0.004 percent by volume) of hydrogen sulfide. I am fairly sure that many other countries also require that fuel gas contain very little hydrogen sulfide. I think the article should make it clear that hydrogen sulfide levels in the end product biogas must be very, very low.

I hope this helps. Regards, - mbeychok 19:19, 16 August 2007 (UTC)


 * After a brief look, I find the article has little references. References is the first step of attempting to get the article to GA, A, or FA status.  OhanaUnited    Talk page   15:29, 17 August 2007 (UTC)

Chartered Institute of Marketing
The original, longer article was at The Chartered Institute of Marketing, which was speedily deleted under WP:CSD as an advertisement (upon checking that article, it did seem to be written with a very promotional tone). The version I deleted didn't assert any kind of notability, which made it speedily deleteable under WP:CSD. You can recreate it again, since based on the first deleted article the organisation definitely appears to be notable, be sure to assert its notability and provide some sources, and avoid being overly promotional. --Core desat 10:17, 29 August 2007 (UTC)

Unknown article
Thanks for your comments. The article was especially prepared by me for Wikipedia and not lifted from elsewhere. It is based on more than 25 years of a career in technical and scientific work within the soft drinks industry, that includes having been R&D manager of an international soft drinks company and scientific consultant to the industry. It is because I am retired that there are no longer barriers to worry about in addressing such a sensitive subject. The topic was given considerable publicity in the UK media (radio & various consumer programmes on TV such as "4 What It's Worth", "Watchdog", "You and Yours" etc) during the 1980s to the mid 1990s, that eventually forced the industry, including the BSI, to take action and reduce the explosion hazards both with glass (explosion) and PET bottles (missiling). In this respect the UK is ahead of other countries in taking corrective action. The topic is well established in the public domain, but not addressed scientifically, by Wikipedia or, indeed any other enclycopedias. As I stated elsewhere, I have avoided referring to my own publications, for obvious reasons, but have included DTI-sponsored studies, inter alia, that refer to my work.

I really have no objection as to where the article goes and am looking for experienced wikipedians to find a suitable location.

Water
I wasn't sure where to start with this, from Water:
 * An advantage of water is that biological processing of wastewater is easy and treated wastewater can be safely led into the sea or a river. However, if the contaminants are toxic and not processable biologically, wastewater has to be incinerated, which is expensive.

Easy? Wastewater incinerated? I guess it's a long article and simplification is needed... but thought you might have ideas on rewording. --Chriswaterguy talk 16:05, 4 November 2007 (UTC)

Anaerobic digestion
Alex, as requested I have been reviewing the Anaerobic digestion article which is an immense improvement on the stub that I originally started editing. It is a considerable credit to the few main contributors and editors.

However, I do have some reservations and I have made one edit to try and set it better in its wider context. To me anaerobic digestion describes the process that occurs whenever organic material exists in a micro-organism rich anaerobic environment. These processes have been harnessed by man to great benefit in a range of different ways which, incidentally, include cold lagoon digestion which I don't think gets a mention. The article reads very much as a description of the thermophilic industrial process and is very weak on the underlying microbiology and the range of occurrences in natural and semi-natural eco-systems. There is also one section on aerobic digestion which seems out of place here.If I can and will try and apply some more balancing edits and I hope you will let me know if you think I'm barking up the wrong tree.

In vessel composting
Hi Vortex,

Are the original author of the in-vessel composting article?

I have some concerns over the process being described and feel it does not reflect what would commonly be refered to as in-vessel composting in the UK and Europe, ie a concrete tunnel system (such as Agrivert and Cambridge Recycling use) or upright metal chambers (such as VCU).

I'd welcome your comment on this, I feel that a member of the public using Wiki for info on systems being built in the UK will not get the right information as the article stands.

I considered re-writing myself, but wanted to discuss this with you, and also considred asking the Composting Association to submit a more detailed article.

Hope you get back to me,

MBT questions
I'm an italian engeneering student and I've contacted you because there are a few points about Mechanical Biological waste Treatment that are not completely clear to me. Are MBT plants a good alternative to waste-to-energy plants? How much money does an MBT plant costs? How big is an MBT plant? Is it true that the plant is energetically self-sufficient thanks to the production of biogas through the anaerobic digestion? Does the plant produce toxic smokes? Everything I know about MBT comes from the omonymous page on Wikipedia, can you suggest me other sources of informations?

(As sent via email)

Hello Maurizio Following your post on wikipedia here are some answers to your questions: Are MBT plants a good alternative to waste-to-energy plants? Yes a very good alternative especially where there is a lot of opposition to incineration, where there are drivers for the best environmental solution and where additional revenues can be gained from green energy. How much money does an MBT plant costs? Clearly this depends on the size and type of technology you are looking at. Smaller plants cost in the region of 20 million Euro (a very rough budgetary figure) How big is an MBT plant? MBT plants size is normally dependent upon the front end sorting element. The plants that we and HAASE supply start at around 50,000 tonnnes per annum. Is it true that the plant is energetically self-sufficient thanks to the production of biogas through the anaerobic digestion? Yes, there is usually a net export of electricity from an anaerobic digestion based MBT plant. A composting or biodrying MBT plant does not however produce any energy. Does the plant produce toxic smokes? No, the only emissions from an MBT plant come from the exhaust gases from the gas engines. Biogas can contain a small amount of H2S which is toxic however there are mechanisms to prevent its formation in the digesters and does not reach the exhaust gases in high concentrations. Everything I know about MBT comes from the omonymous page on Wikipedia, can you suggest me other sources of informations? Enviros waste technology site http://www.waste-technology.co.uk/ The Juniper MBT report is a comprehensive study of many different MBT processes. Its a couple of years old now but contains very good information: http://www.juniper.co.uk/Publications/mbt_report.html More information can be found on HAASE technologies at the following pages www.clarke-energy.com and www.haase.de.

Why am I leaving Wikipedia?
Take a good look at my user page! I believe it documents that fact that I have been a long time contributor of good articles related to my many years of engineering experience.

So why have I decided to leave Wikipedia? Because I have grown weary of the revisions made by unexperienced people who think they know a subject when they really don't know it. I am also weary of people who make revisions because they "know better than anyone else". In particular, the actions of one young postgrad student who calls himself Headbomb with whom it is impossible to reason because of his firm belief that he is infallible ... and that he and only he "knows better than anyone else". His attitude has finally been the last straw in making my decision to leave Wikipedia. I am simply tired of trying to reason with the likes of Headbomb.
