This process not only alleviates the pressure on municipal waste systems but also yields renewable resources that integrate into circular economic models. Reduction of Landfill Dependence Discarded tyres are notoriously difficult to compact or degrade. When accumulated in landfills, they occupy substantial space, leach harmful compounds, and ...
Final location: Waste that cannot be recycled or reused is deposited in controlled landfills or incinerated under environmental regulations. Safe disposal methods include sanitary landfills, energy-recovery incinerators, hazardous waste storage, etc. ...
Real-time data for landfills to get ahead of unfolding odour issues It’s essential for a landfill site to be able to visualise data and insights in real time. ...
About Ali R. Abedini, Ph.D. Ali is a Landfill Gas Specialist with Sperling Hansen Associates Inc. who are consultants specializing in providing solid waste management services including landfill design, operation, and closure plans; transfer station design and operation plans; landfill fire extinguishments and risk management, and training; ...
Previously part of the UK’s Environment Agency SITA UK Monitoring team, as well as developing SITA’s landfill gas monitoring, Tommy was also a key figure in introducing the TDL-500 ppm methane detector to improve SITA’s landfill surface emission modelling. ...
At high concentration of landfill leachate, the effect of operating pressure can be negligible. The maximum amount of RFR was 0.961 for raw landfill leachate. Flux decline data were also obtained for the filtration of landfill leachate. ...
This article describes the risk assessment of gaseous emissions from the municipal solid waste at Rafah landfill, Palestine. In this study, Gas-Sim model was used to quantify the gaseous emissions from the landfill and the Land-Gem model was used to verify the results. ...
The composition of leachate at a landfill depends on the landfill type (hazardous, non-hazardous and inert) and, within the same landfill, on the period during which the landfill has been in operation. Therefore, depending on the age, a distinction can be made between young leachate, found at landfills in ...
Through these sites, there is uncontrolled emission of methane and landfill gas. The landfill gas has tremendous potential in terms of converting and using them as source of fuel. ...
The operating parameters in the electro-Fenton process were simulated using computational fluid dynamics (CFD). The effects of H2O2/Fe2+ molar ratio, current density, pH and reaction time were numerically investigated. The results were compared with the experimental data. The simulated data showed that maximum chemical oxygen demand (COD) removal was around 91.52% at pH of 3.27, ...
Since, the direct measurements of landfill methane emission found to be difficult, the methane emission potential of the open dumps in Chennai has been estimated using first–order decay models such as TNO, LandGEM and zero–order model (EPER model, Germany). The resulted methane emission was around 33 × 106 m3, 36 × 106 m3 and 52 ...
In this study, SO has been concurrently combined with both penalty functions and a Grey Programming (GP) technique in order to efficiently generate sets of numerous, good policy alternatives an approach referred to as modelling–to–generate–alternatives. The efficacy of this approach is illustrated on a planning problem for expanding a landfill and municipal waste ...
However, waste materials containing PLA are frequently disposed of in municipal landfills, which are operated anaerobically. PLA anaerobic sludge digestion results are acquired to elucidate effects of the degrading temperature on PLA biodegradation. ...
The coupling model was developed for describing the gas transport and heat release. ...
The objectives of the research described in this paper are to: study the composition of fresh Municipal Solid Waste (MSW); study the effects of decomposition on physical characteristics of MSW in bioreactor landfill. Initially, composition of the fresh MSW constituents was determined based on 14 bag MSW samples. Then, four small-scale bioreactor landfills were simulated in laboratory and samples ...
Variations in the characteristics of leachate from the landfill of a Common Hazardous Waste Treatment Storage Disposal Facility (CHWTSDF) in South India was analysed in terms of pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), COD, calcium, magnesium, sodium, potassium, total alkalinity, chlorides, sulphates and selected heavy metals (Pb, Cd, Cr+6, Zn and Ni). The ...
To the authors' knowledge, there is no published work, relating biodegradation and settlement of municipal solid waste (MSW) in bioreactor landfills together. The present mathematical model is developed to simulate the biodegradation of MSW in anaerobic bioreactor landfills and predict the strength of leachate in terms of volatile fatty acid ...
Landfills are one of the groundwater pollution sources in Gaza Strip. This study focuses on two landfills operating in Gaza Strip; the first is Dear Al Balah landfill which has a lining system and the second landfill is Gaza landfill which does not have a lining system. The main objective of the present study is ...
An alternative technique of landfill remediation known as 'Phytocapping' was trialled at Rockhampton, Australia. Twenty one tree species were established on two types of phytocaps (thick cap; 1400 mm soil and thin cap; 700 mm). The trial was monitored for plant growth, transpiration loss, canopy rainfall interception and methane oxidation. The results show that the tree species can intercept ca. ...
The study also addresses a risk assessment technique and model for estimating landfill risks at the first Hungarian hazardous waste disposal site as Aszod.Keywords: hazardous wastes, waste disposal, Hungary, landfill, risk analysis, economic risks, environmental risks, environmental policy, public health, safety, waste management, risk ...
