FAQs

Is my landfill a good candidate?
Landfills with at least 8-10 years of waste, which are composed of at least 80-90 percent municipal solid waste and receive at least 1,100 tons of solid waste per day are good candidates for high-BTU project development. Landfills should have a minimum of 10-12 years of remaining capacity to ensure ongoing successful operation.

What other criteria apply to high-BTU landfill candidates?
In addition to being a good candidate landfill as described above, the proximity of the landfill to existing pipelines with acceptable gas quality tariff conditions is also very important. The expense of building a pipeline can be a significant factor in the economic viability of a high-BTU landfill gas project. The local pipeline must also have the appropriate certification and tariffs for transportation of the gas to market.

Can I be assured that the level of revenue generated from this process is enough to cover the costs?
There are no additional costs to the landfill owner/operator. Renewco bears all of the capital and operating costs associated with the landfill gas processing plant. The royalty revenue for the landfill drops straight to the bottom line.

How long does it take to get this system up and running?
From the time the large processing components are ordered, a typical project will usually be up and running in about 12-16 months. Any permitting or regulatory delays may extend the timeline.

You mentioned that you need to start with "good gas." What does this mean?
To meet the quality standards required for high-BTU, pipeline quality natural gas, the landfill gas must have a fairly "tight" gas collection and control system (GCCS). This means that the system has very little air intrusion (one of the principal components of air, nitrogen, is not easily removed by the process, and can require expensive removal equipment). Renewco will typically make additional investments to add interstitial wells or make other improvements to the GCCS to maximize gas quality and quantity. High levels of sulfur in the gas can also require additional processing equipments, although this is manageable in some cases.

If my landfill isn't considered a good candidate for this process, how can I enhance it?
In some cases the landfill cell design and the way it is filled can inhibit the collection of gas, so by altering the operating plan, the gas can be made more accessible.

How many people will Renewco typically employ at the onsite processing plant?
While dozens of jobs are created during the construction phase of a project, a typical landfill gas plant will employ three to four plant personnel on an ongoing full time basis.

I've worked hard to establish a good relationship with our neighbors. Will the plant increase ambient noise in the area? What other impacts might it have on the community?
Renewco is sensitive to the concerns of the local community. If the landfill cannot prosper in the community, a landfill gas project cannot succeed. The plant's processing equipment is located inside a building, which dampens any external noise signature. Typically, there are no sound levels off the landfill site associated with the processing plant. In most cases, our additional investment in the well field and GCCS improve gas collection efficiency, actually reducing odor and emissions. The community also experiences lower pollution levels because the landfill no longer vents or flares methane to the environment. Instead it is treated, contained and sold, where it offsets the need to burn fossil fuels.

What can I expect in terms of reduced emissions?
For a landfill that does not already have a GCCS installed, there is a significant reduction in methane, hydrogen sulfide, and volatile organic compound emissions. This results in substantial reductions of greenhouse gas emissions, as well as criteria pollutant emissions. For landfills with an existing GCCS, the emissions associated with the combustion of the methane component of the landfill gas in the flare are reduced to nearly zero, as the methane is captured and sold, instead of being burned in the flare.

How much energy is required to run the processing facility? Won't my energy costs increase?
The energy required to run the facility varies based on the volume of gas processed. However, the electric service connection and all associated utility bills are paid for by Renewco, so the landfill will experience absolutely no increase in electric utility operating costs.
