Landfill Gas Formation, Recovery and Emission in The Netherlands

“…So in general, there seems to be little or no risk of methane emissions from a capped landfill; • For closed landfills, emission measurements indicate that efficiencies vary between 10 and 90%. The low end of this range comes from measurements by Oonk and Boom (1995) on Dutch projects in the early 1990s. At this point in time, most Dutch landfill gas projects were initiated, designed and also operated by energy companies.…”

“…Methane emissions are subsequently calculated, using a dispersion model. Measurements were performed in the early 2000s, at a moment where more attention was paid to design and operate the landfill gas collection to reduce landfill gas emissions, compared to the measurements of Oonk and Boom (1995). Measured collection efficiencies were 8, 50, 55 and 33%.…”

“…For capped landfills, an efficiency of 60-95% was estimated, with the low end of the range referring to capped landfills without proper sealing at the bottom or sides. Oonk and Boom (1995) describe methane and carbon dioxide emission measurement on 21 Dutch landfill sites using a one-dimensional (1D) mass-balance method in the period 1991-1994. In such a 1D mass-balance method, methane flux along a vertical line, perpendicular to the landfill surface is measured and correlated to the distance to the edge of the landfill.…”

Landfill gas collection seems to be overestimated in many countries with methane emission inventories. When no measurements are available, IPCC guidelines allow a default collection efficiency of 20% can be used for the methane generated on landfills with collection. However many Annex 1 countries estimate landfill gas collection to be much higher than 20%. This article reviews available information on collection efficiency. Collection efficiency depends on the phase of the landfill. During operation, a large part of the methane potential is generated. In the absence of a collection system, most is released to the atmosphere. In many cases, landfill gas collection only starts after closure and in this period collection efficiencies generally increases. High efficiencies are achieved, when the site is capped with an impermeable liner. For estimation of collection efficiencies, different landfill types should be distinguished: (a) closed landfills without gas collection; (b) capped landfills; (c) closed landfills with temporary cover and gas collection; (d) landfills in operation with and (e) landfills in operation without gas collection. For landfills with state of the art liners, collection efficiencies can be 90-100%. For closed landfills, reported efficiencies range from 10-90%. For landfills in operation, efficiencies are 10 to 80%.

The Netherlands has taken various measures to reduce the emission of methane from landfills, such as less waste disposal, separate collection of biodegradable waste, use of landfill gas for generating power, and flaring of landfill gas. These measures have led to a dramatic reduction in emissions. But more can be done by taking additional measures. The question of whether the costs justify the expected yields is an important one, and has been addressed in the research. Four types of additional measures have been selected as potential measures which show great promise: (1) flaring of low-calorific gas, (2) additional gas extraction wells, (3) early sealing of landfill, and (4) optimization of existing landfill gas extraction systems. Low-calorific gas flares are expected to be most for promising in future for landfills where extraction systems are already installed. The costs of installing additional landfill gas extraction wells usually exceed the revenues. Early sealing of a landfill is only feasible when this measure has additional benefits (such as reduced leachate amounts). This shall be detailed in a business case for the specific landfill. Quick wins can be achieved by improving the operation of existing landfill gas extraction systems.
