Worldwide Offer: Landfill Gas Utilisation Feasibility Study Service
Enviros Consulting offers a full service to landfill owners to assess future gas yield from any landfill, to advise on both the cost of installation of power generation, and on the profitability of generating energy from waste (EfW), in the context of national and international subsidies available.
The first stage is a gas yield and scoping study, provided by Enviros landfill gas consultants. The cost of this stage is from £1,000 (GB Pounds), which will provide a yield evaluation for landfill gas utilization projects.
If this initial investigation indicates that the opportunity for energy recovery from the gas is significant, it may be possible for Enviros to share the consultancy costs of later stages of investigation etc, with the landfill owner, to ease the burden of setting up an EfW project on the site owner's cash flow.
The reward sharing method provides added assurance to site owners on the quality of the consultancy advice which will be provided, as it creates a financial incentive for the consultant to also go on to secure real benefits for the site owner/client.
The second stage is a detailed feasibility study, which normally includes the following:-
- Outline design, and preliminary specification: for a suitable landfill gas management and utilisation scheme;
- Cost estimate: based upon the above requirements. Includes initial estimation of the cost of connection into the local power grid by our Mechanical & Electrical Engineers;
- Advice on any national or international grants, or subsidies: (eg NICE (UK) renewable power commitment related, or as paid under the Kyoto Carbon Credits programme (3rd World Economies)), and an initial valuation of such benefits;
- Revenue estimate: based upon the stage 1 work, or on any additional data collected as a result of recommendations at stage 1;
- Profitability forecast: based upon a cash flow and revenue analysis by Enviros' economic and financial experts;
The third stage for all viable sites is the tendering and and contract negotiation stage.
During this stage Enviros' experts would enter into a tendering exercise on behalf of the owner to obtain detailed comparative offers from private sector developers willing to take on an EfW concession for the site. The developer would install the gas collection and power generation system and operate it. In return the owner will receive royalty payments for the duration of the concession period.
These schemes are very popular, and confer the following potential advantages:-
- Revenue for the site owner;
- Large environmental benefits by reducing greenhouse gas;
- Reduced risk from landfill gas migration and reduced odour emissions, plus improved general air quality in the vicinity of landfills (for all landfills where there would not otherwise be an actively pumped gas collection and flaring system installed);
- May help to finance collection and capping systems, which will reduce landfill impacts and enhance the land in the years to come;
- Additional employment created in the operation and maintenance of the plant.
Most planning bodies and local communities support EfW schemes. So there is also a public relations benefit, which is also a motivation for landfill gas utilisation schemes.
The stage 1 work to assess future gas yield includes the use of GasSim Software to model the gas generation rates for the landfill site from the present day for up to 30 years post-closure. In our experience (from data we have collected ourselves over many years), GasSim often generates a conservative (pessimistic) estimate. For this reason we also carry out our own Enviros Predictive Gas Generation Model, and we weigh these results against those obtained from GasSim, to provide the best realistic estimation of generated rates. We also include consideration of maximisation of gas yield by operational methods, wherever these are likely to be permissible to the regulators and conducive to general landfill operations.
Landfill Gas Utilisation Feasibility Study Request Form
We would be pleased to provide further information on our service, and of our track record, and will also provide confirmation of the price of the consultancy work proposed. Please complete the form below as fully as possible, or in the unlikely event that the form does not perform correctly in your browser, please include the same information in an e-mail to GasUtilisation@landfill-gas.com .
You may also use this form if you already have EfW systems installed to seek an audit, or a review of your current concession agreement - especially if the projected waste filling rates and/or types of materials accepted at a landfill, are due to change.
