Active Landfill Gas Extraction System Design image

Landfill Gas Extraction Ebook cover imageThis is the ebook you need
if you are involved in any way with
design, installation, operation and maintenance, including

Over 50 pages of essential information on landfill gas extraction system principles to bring your knowledge up to a standard to begin to design your own extraction systems, appraise designs, or assess financial worth of an EfW project.

The information in this ebook is UK based but the principles apply to all those developing and restoring sanitary containment landfills to comply with European Union and other internationally recognised landfill standards.

What you get in this one unique and low cost ebook:

list tick image Background information to very quickly introduce you to all the factors you should think about when considering a landfill for landfill gas both in the developed and developing nations. This includes information about the fianance potentially available for EfW schemes through Carbon Credits schemes, and subsidies in the UK such as ROCs.

list tick image An explanation of landfill gas yield modelling and the methods of assessment essential to understand the capability of your landfill to produce methane gas in sufficient quality and quality and for long enough to pay for itself and make you those all-important profits. Get this wrong and your EfW project will never make a profit

list tick image How to successfully sample and test the landfill gas which is again essential to understanding profitability initially and then monitor and optimize the yield from the site later

list tick image The principles of successful landfill gas extraction pipework design and how to successfully design the interconnections in the landfill gas field, and locate "Knock Out Pots". Ignore this and you will find that the field gas extraction pipes will block within months or even just weeks and the investment may be made worthless in extreme cases. At the very least substantial additional time, cost, and delay would be caused by ignoring these principles.

list tick image All the common gas well types are explained with there specific advantages and disadvantages. This could save you a ton of money as selecting the wrong well type alone could cost many $1,000's in wasted money.

No landfill gas extraction system for flaring and/or Energy from Waste (EfW) use can be successfully designed and implemented without a knowledge of the principles described in this ebook.

For anyone wishing to start designing Landfill Gas Extraction Systems for either purpose, this will get you started on the right track fast. You will, after reading this ebook, be able to begin you design and talking to the Energy from Waste experts who will supply the gas engines, without delay.

Provided that you have a suitable practical and/or engineering based background you will be able to successfully hold conversations with the landfill gas EfW specialists without fear of, your asking embarassing questions through lack of knowledge, and mis-understandings.

You will be able to be confident that you will be able to talk their language and successfully integrate the site's gas extraction system with the gas engines and other plant installed.

For anyone already operating a landfill gas extraction system you should get this ebook as it will explain why you have to do many things that may have been handed down to you as must do's without a full appreciation of the reason behind them.

For anyone considering financing a landfill gas extraction system you should get this ebook as you will then understand the opportunities, cost implications and risks involved in the best way possible.


Landfill Gas (LFG) Energy from Waste (EfW) projects are nowadays very often described by their owners as highly profitable. We have heard landfill operators even claim that their EfW production is more profiatble than the commercial operation of the landfill itself!

Furthermore, LFG EfW is becoming more profitable by the week as other non-renewable energy prices rise. No landfill owner should rest until investigating the EfW possibilities for their site and you can download this ebook and after making payment through our secure system (owned by the owners of global auction site "eBay") start reading it within just a few minutes.

You can pay pay it in your own currency without a Paypal Account or through Paypal using your bank account (most countries). Or, if you have a credit or debit card and don't yet have a Paypal account you can very quickly set up a new Paypal account for FREE with them, but that is not essential to make this purchase.

orary Introductory Price

Please get this very soon if you want it. I would not want to disappoint you if you return tomorrow and I have raised the price.

I am carrying out an initial market pricing experiment after being told that I am crazy because I am offering this product at far too low a price. Certainly, I have seen for myself other web sites where this sort of highly specialized information is only available for more than £100 GBP ($179 USD), and even 3 or 4 times more expensive than that on other consultant's web sites.

I am only offering it at this ultra low price today to sell the first 25 copies only and obtain feedback and general comments.

The fact is that the cost of this ebook is nothing when compared with the money to be made from landfill gas energy from waste schemes, and if I was to do this work for you myself on an hourly fee basis I would charge (and get) fees of between USD equivalents of $100 and $150 per hour.


This ebook can easily save you having to pay for several days of expert advice let alone hours, so I have put a $800 value to it. But, I am not even chargng you the equivalent of even one hour of consultancy.

In fact this amount would be chargeable if a design consultant had merely lifted the phone and answered a few questions, as it amounts to less than half an hour at normal fee rates.

OK. I'll take ALL the risk that you don't like this. If for any reason you were unable to contact me Paypal will refund you - no questions asked.
