OPERATIONAL FACTORS DETERMINING PERFORMANCE OF LANDFILL GAS PROJECTS UNDER KYOTO PROTOCOL MECHANISMS

Waste management is inevitably linked to carbon management since there is a direct relationship between the treatment and disposal of waste with certain emissions released to the atmosphere. The nature and amount of emissions depend on the method used. The threat of climate change has focussed attention on greenhouse gas production from waste disposal. Landfill is the oldest form of waste treatment due to its historical simplicity of ‘hide’ the waste. Undoubtedly, the concept of Reduce, Reuse and Recycle (3R) is the most sustainable waste management approach nowadays. However, the evolution from landfilling to the 3R concept is happening gradually and at different rates worldwide.

Landfills are one of the largest sources of methane in the world and therefore, a major contributor to the greenhouse effect. Theoretical landfill gas (LFG) generation models are widely applied methods for quantification of methane production in landfills. These models predict the amount of methane produced based on waste deposited, applying assumed rates of methane generation. In vast majority of cases, inexperienced modellers without consideration of operational factors are using these generic rates resulting in underperformance of the projects. Under the Kyoto Protocol (in case of this paper the Clean Development Mechanism or CDM), the LFG gas potential and the CDM performance of the registered projects needs to be reassessed in order to determine the amount of methane that will be destroyed in a landfill extraction and utilization system and converted it into Certified Emission Reductions (CERs). This assessment, followed by an economic analysis, allows developers to estimate the feasibility of the project

CARBON CREDITS TRADING WITH BIOLOGICAL METHANE OXIDATION AND IN-SITU STABILISATION OF LANDFILLS – PREMISES AND PERSPECTIVES
© IWWG International Waste Working Group (10/2007)
Global warming is a result of a change in the atmospheric radiative balance caused by anthropogenic emissions of so-called greenhouse gases (GHGs). Extensive research over the last two decades has resulted in a detailed understanding of the scientific background of climate change (IPCC, 1990, 1996, 2001, 2007a). Although considerable ambiguity remains on concrete measures to be taken, the scientific facts have now, at last, been accepted by practically all relevant governments and stakeholders. The urgent necessity for a drastic reduction in GHG emissions is, however, evident. According to the report on mitigation of climate change recently published by the Intergovernmental Panel on Climate Change (IPCC 2007b), a stabilisation and subsequent decrease of GHG emissions within the next 15 years will be necessary in order to limit the increase of the global mean temperature to 2 °C.

A YEAR’S MONITORING OF A PASSIVE LANDFILL GAS BIOFILTER
© IWWG International Waste Working Group (10/2007)
In landfill rehabilitation programs, biogas management is a major issue. If biogas production is not sufficient for a flare to perform—methane concentration at an average of 30 % and biogas generation under 10 cubic metre per hour—, alternative solutions can be imagined. In particular, numerous writers have shown that it is possible to treat some of that methane by oxidation in the landfill cap or even by using a biofilter. This study takes a look at a French experimental site using this kind of landfill gas treatment.

COMPARISON OF A TUNABLE DIODE LASER APPROACH WITH STATIC CHAMBERS FOR DETERMINATION OF SURFACE METHANE EMISSION
© IWWG International Waste Working Group (10/2007)
Increasingly there is a need to determine methane emission rates from landfills. These determinations are needed for greenhouse gas inventories, for constraining estimates of emissions of non-methane organic compounds and for determining the efficiency of gas collection systems. Measurement campaigns to determine methane emissions from landfills are not overly common although a number of studies have been published, frequently using static chambers as a measurement vehicle (Bogner et al., 1997a, b, 1993). The disadvantage of this approach is that it is time consuming and requires a large number of measurements to constrain estimates from large landfill surfaces. The chamber approach also will not detect emissions from above the soil surface which might be due to leaky gas plumbing fixtures.

DIFFUSED LANDFILL GAS EMISSION MONITORING IN NON-HAZARDOUS WASTE LANDFILLS: STUDY CASES
© IWWG International Waste Working Group (10/2007)
An articulated monitoring plan was arranged in order to set up an adequate measure campaign of the possible landfill gas escape from landfill body, with the aim of assuring scientific significance and coherence for the evaluation of vertical landfill gas emissions (i.e. from landfill surfaces in contact with atmosphere) and of horizontal landfill gas emissions (i.e. landfill gas migration through soil and subsoil toward the outside of landfill cultivation area).

Pflichten des Deponiebetreibers aus Vorschriften zu Arbeitsschutz und Anlagensicherheit
© Verlag Abfall aktuell (1/2015)
Auf einer Deponie sind insbesondere die Beschäftigten in der Deponiegasanlage einer Reihe von Gefährdungen ausgesetzt. Es ist die Pflicht des Deponiebetreibers, die Anlage so sicher zu betreiben, dass keine unzulässigen Beeinträchtigungen der Bevölkerung und der Umwelt entstehen sowie den Betrieb so zu regeln, dass von den eingesetzten Arbeitsmitteln (Werkzeuge, Geräte, Maschinen und Anlagen) keine Gefährdungen für seine Beschäftigten ausgehen bzw. die Gefährdungen so gering wie möglich gehalten werden.
