HORSEY TOLL FARM (Stanground, Park Farm and Cardea affected) NEW WASTE BIO-GAS SITE FOR GERMAN FIRM






http://parkfarmneighbourhoodwatch.blogspot.co.uk/2015/05/hooray-horsey-toll-farm-stanground-park.html  Links to original post...


Its been pointed out that Horsey Toll, isn't an incinerator in the Cereste style, Granted, no one said that it was! The Horsey Toll plant digests waste and rotting vegetation, and from it comes a flammable biogas which can be sold on in industrial quantities. When the digester isn't working or down the gas continues to collect, and for safety sake it has to be 'flared' or 'incinerated'  
The planning clearly calls for a flare pipe. 









Read this recent research paper Methane emission factors for biogas flares...
Biogas, produced by the anaerobic digestion of organic material, is primarily a mixture of
methane and carbon dioxide, typically in equal measures.



It may have trace amounts of other compounds, depending on the source organic material. Landfills, sewage treatment plants, anaerobic digesters and manure storage facilities all produce biogas.





Methane Flare Pipe

This gas may be flared, either continuously to reduce the emissions of methane, or intermittently when the energy conversion equipment (e.g., genset, boiler) is not operating.

Landfill gas is often burned in an enclosed flare, or an elevated flare with a wind shroud. In the
agricultural setting, the flare equipment is generally a simple elevated pipe flare, perhaps
equipped with a pilot burner and a wind shroud. The biogas may be provided at low
pressure.


The Flare Test Facility (FTF) of Natural Resources Canada (NRCan) is a wind tunnel
dedicated to testing flares. For the biogas tests a simple pipe flare was used, 101.6 mm (4
inches) diameter, firing mixtures of natural gas with carbon dioxide or nitrogen. Dilution
levels were 0%-v, 20%-v, 40%-v and 60%-v. The last two levels cover the likely range
for biogas. The emissions were measured and combustion efficiency calculated.

Flares are commonly considered at least 98% efficient if the gas has heat content above
7.5 MJ/Nm3 (200 BTU/scf, a biogas with approximately 20%-v methane, balance inert gas).
Our results show that this heat content threshold is not useful for biogas
(methane/carbon dioxide mixture). Wind produces a significant decrease in combustion
efficiency. The decrease in efficiency is indicated by unburned methane, a strong GHG.
The combustion efficiency and destruction efficiency are correlated with a single
dimensionless factor that incorporates the wind speed, pipe diameter, mass flow rate of
the biogas, heat content (mass-basis) of the biogas, and the flammability limits. Natural
gas/nitrogen mixtures have a separate correlation with the same dimensionless group.

Methane emission factors for biogas flares

Clearly had the original full blogpost on here (alerting residents at the eleventh hour - when Cambridge and Peterborough  councillors had sat on their hands hoping to sneak it through during the Election period) been properly read through, it would have been understood.     Simply we went to great lengths to explain the biogas (methane and carbon dioxide)  process, so this this comment should not arise!   The incineration part is the huge permanent flare pipe which essentially 'burns off' 'flares' or 'incinerates' excess methane and other gases ( but not all of it) when the  digester is processing or resting.....    To blandly claim  the plant meet all requirements and that only a couple of traffic movements a day are involved is frankly daft. Who is going to physically count the movements? Remember this plant has to be constantly fed with ....there is no other word for it - CRAP!  Some of it will trundle right down your street...you'll certainly smell it!

NUJ CODE OF CONDUCT

NUJ Code of Conduct

The NUJ's Code of Conduct has set out the main principles of British and Irish journalism since 1936.

The code is part of the rules and all journalists joining the union must sign that they will strive to adhere to the it.


Members of the National Union of Journalists are expected to abide by the following professional principles:

A journalist:

1 At all times upholds and defends the principle of media freedom, the right of freedom of expression and the right of the public to be informed

2 Strives to ensure that information disseminated is honestly conveyed, accurate and fair

3 Does her/his utmost to correct harmful inaccuracies

4 Differentiates between fact and opinion

5 Obtains material by honest, straightforward and open means, with the exception of investigations that are both overwhelmingly in the public interest and which involve evidence that cannot be obtained by straightforward means

6 Does nothing to intrude into anybody's private life, grief or distress unless justified by overriding consideration of the public interest

7 Protects the identity of sources who supply information in confidence and material gathered in the course of her/his work

8 Resists threats or any other inducements to influence, distort or suppress information and takes no unfair personal advantage of information gained in the course of her/his duties before the information is public knowledge

9 Produces no material likely to lead to hatred or discrimination on the grounds of a person's age, gender, race, colour, creed, legal status, disability, marital status, or sexual orientation

10 Does not by way of statement, voice or appearance endorse by advertisement any commercial product or service save for the promotion of her/his own work or of the medium by which she/he is employed

11 A journalist shall normally seek the consent of an appropriate adult when interviewing or photographing a child for a story about her/his welfare

12 Avoids plagiarism The NUJ believes a journalist has the right to refuse an assignment or be identified as the author of editorial that would break the letter or spirit of the code.

The NUJ will fully support any journalist disciplined for asserting her/his right to act according to the code
