“…All the landfills, which were described in more detail in previous studies (the Glatved landfill was also presented under the name of Reno Djurs), were still in service and at that time only received low-organic waste fractions for permanent disposal (Mou et al, 2014;Mønster et al 2015). They had different ages and provided waste data from various starting years of disposal until year 2012.…”

Methane (CH 4 ) generated from low-organic waste degradation at four Danish landfills was estimated by three first-order decay (FOD) landfill gas (LFG) generation models (LandGEM, IPCC, and Afvalzorg). Actual waste data from Danish landfills were applied to fit model (IPCC and Afvalzorg) required categories. In general, the single-phase model, LandGEM, significantly overestimated CH 4 generation, because it applied too high default values for key parameters to handle low-organic waste scenarios. The key parameters were biochemical CH 4 potential (BMP) and CH 4 generation rate constant (k-value). In comparison to the IPCC model, the Afvalzorg model was more suitable for estimating CH 4 generation at Danish landfills, because it defined more proper waste categories rather than traditional municipal solid waste (MSW) fractions. Moreover, the Afvalzorg model could better show the influence of not only the total disposed waste amount, but also various waste categories. By using laboratory-determined BMPs and k-values for shredder, sludge, mixed bulky waste, and street-cleaning waste, the Afvalzorg model was revised. The revised model estimated smaller cumulative CH 4 generation results at the four Danish landfills (from the start of disposal until 2020 and until 2100). Through a CH 4 mass balance approach, fugitive CH 4 emissions from whole sites and a specific cell for shredder waste were aggregated based on the revised Afvalzorg model outcomes. Aggregated results were in good agreement with field measurements, indicating that the revised Afvalzorg model could provide practical and accurate estimation for Danish LFG emissions. This study is valuable for both researchers and engineers aiming to predict, control, and mitigate fugitive CH 4 emissions from landfills receiving low-organic waste.Implications: Landfill operators use the first-order decay (FOD) models to estimate methane (CH 4 ) generation. A single-phase model (LandGEM) and a traditional model (IPCC) could result in overestimation when handling a low-organic waste scenario. Site-specific data were important and capable of calibrating key parameter values in FOD models. The comparison study of the revised Afvalzorg model outcomes and field measurements at four Danish landfills provided a guideline for revising the Pollutants Release and Transfer Registers (PRTR) model, as well as indicating noteworthy waste fractions that could emit CH 4 at modern landfills.

“…In this study, two different experiments were performed: the biochemical methane potential (BMP) tests [7] and the lysimeter test [8][9]. As a result, we analyzed the effects of applying the same condition of energy recovery projects using incoming household and demolition wastes of LS2 on the production of LFG and hydrogen sulfide (H 2 S) of LS3 in the future.…”

The volume and composition of landfill gas (LFG) [1] as a product of biochemical degradation in the landfill during landfill disposal [2] has a great impact on the operation of a landfill [3]. Therefore, in order to operate landfill sites economically and in an environmentally friendly manner, the characteristics of landfill wastes should be identified prior to demolition planning and operation of the landfill sites. The amount and nature of LFG vary greatly depending on the energy recovery and recycling projects for landfill waste. In other words, if waste energy recovery is carried out before waste landfill, then the inorganic waste after waste pretreatment and residue from the thermochemical energy recovery are left as landfill waste. Therefore, the volume of LFG generated differs in direct landfills where energy recovery is not carried out. In addition, whether or not landfilling solidified sludge [4][5], mixed landfilling of the total wastes, and the separate landfilling of specific wastes are carried out also affect LFG output.The influence of the traditional method of direct landfilling of total wastes on the characteristics of the landfill such as LFG production due to energy recovery and separate reclamation of the waste materials can be estimated, making it possible to better plan the energy recovery system and energy recycling projects [6].Pol. J. Environ. Stud. Vol. 27, No. 6 (2018), 2613-2622 Original Research AbstractIn order to conceive of an efficient way to manage a landfill, we conducted an exemplary study of the Sudokwon Landfill Site in South Korea, with particular regard to the influence of energy recovery from waste. As a result of the BMP test, biogas production of demolition waste was much lower than household waste even in the same waste type. Gas production from the residual substance of energy recovery from waste (ash), waste soil, and the sludge landfill cover material was almost zero, but the solidified sludge showed 4.1 times greater than digested sludge due to the fewer pozzolanic reactions. Lysimeter test results show that the total amount of landfill gas was reduced to about 1/27 when combustible waste is buried after the recovery of energy, but, in order to be able to completely eliminate the landfill gas collecting system in a newly managed landfill, solidified sludge should not be disposed of in the landfill site. In addition, the maximum concentration of hydrogen sulfide was 60.9×10 3 ppm, when total waste was mixed and landfilled. However, the concentration of hydrogen sulfide decreased to about 1/6 and the total load largely decreased to about 0.9% when applied to landfill waste after energy recovery.
