Formulation of a landfill pollution potential index to compare pollution potential of uncontrolled landfills
Generally speaking, landfilling is one of the prominent methods of waste disposal around the globe, but some under-developed and developing countries still continue to practice uncontrolled open dumping of waste. These uncontrolled landfills pose a relatively high threat to the various elements of the environment in comparison with the conventional engineered landfills that are used in many ...

Treatment of municipal landfill leachate using magnetic porous ceramsite carrier
In this study, porous ceramsite carrier was modified using magnetic material as raw material. The magnetic porous ceramsite carrier was applied to the treatment of municipal landfill leachate. The results showed that the removal efficiency of chemical oxygen demand (COD), NH3-N and Cr6+ in the supernatant were all more than 90% after 30 days with the aeration rate of 3 L/h, the ...

Advanced Oxidation Processes (AOPs) for reduction of organic pollutants in landfill leachate: a review
Uncontrolled municipal landfill leachate during landfilling can seriously pollute groundwater, surface water and soil. Over the past decades, a variety of Advanced Oxidation Processes (AOPs), primarily utilising hydroxyl radicals to effect water purification, have been frequently investigated for treatment of landfill leachate. This paper first summarises the typical characteristics of organic ...

Study of colloidal content and associated heavy metals in landfill leachate: a case study of El-Akader landfill site: Jordan
Landfill leachate samples were collected anaerobically at six locations at the El-Akader landfill site in North Jordan. The collected leachate samples were separated into size fractions with special attention to the distribution of colloids and associated heavy metals. The fraction sizes were 1.2 µm. The maximum concentrations of heavy metals in the analysed leachate samples were Cd 0.6 µg/l, Ni ...

Application of leachate pollution indices for assessment of leachate pollution potential of landfills (a case study of an unlined landfill with lime sludge and fly ash)
Leachates from unlined landfills cause environmental degradation and health hazards due to resultant ground water pollution. Their pollution potential can be measured on a comparative scale using leachate pollution index (LPI). The selection of index involves 18 pollution parameters, their weightages and the sub–index values. The concentrations of pollutants are obtained from toxicity ...

Geosynthetics in the Volgermeerpolder - case study
The Volgermeerpolder (NL), which was once a landfill site for heavily polluted household and industrial waste, has been cleaned up and turned into a nature reserve. This is the largest soil remediation operation in Dutch history. With the aid of TenCate Geotube, clean sludge was converted into a natural cap (a layer of clean soil) on top of the seal. TenCate GeoDetect is used to monitor the seal ...

Decentralized wastewater treatment system for Xom Cau 1 – Kieu Ky Commune: An ADB-funded Pilot and Demonstration Activity with BORDA-Vietnam in Vietnam
As Asian cities grow and develop, so too do the peri-urban areas surrounding these cities, where rural and urban aspects both play a role in the daily lives of citizens in these areas. However, these peri-urban areas often go largely unrecognized by city policymakers, who place emphasis on the urban city center for their development planning. This has resulted in some of these peri-urban areas ...

iDetec – Competence center for innovative landfill technology - Case Study
Landfills remain an indispensable part of global waste management. iDetec offers solutions in the area of modern landfill technology. Despite the German landfill ban in 2005, and despite all efforts of modern cicular economy, landfills still play an important role as pollutant sinks. Landfill operators face various challenges, from the aftercare and remediation of former MSW dumps to the ...

Grab A Tyre Pyrolysis Plant Available For Sale And Start Recycling
Efforts to recycle today are ramping up, and those waste tires just can't get to the landfill. It's a shame once they do, especially when they may be recycled into resources that can be used for various reasons. You get pyrolysis oil, carbon black as well as the steel that could be recycled. You may not use a use for all the products, nevertheless, you can offer those to someone that does this ...

The impact of landfills on the air quality of towns: a simple heuristic model for the city of Palermo
In this study, the landfill of Palermo, is investigated as a potential source of the unusual methane concentrations found in the urban context. The source for these pollution episodes is identified by means of a simple heuristic method. A cross-correlation analysis between wind data and methane concentration levels is also used to confirm the hypotheses formulated. Doppler Sound Detection And ...

Electrochemical treatment of landfill leachate
Electrochemical methods can offer an elegant contribution towards environmental control as electrons provide a means of removing pollutants by redox reactions. In the process of electrochemical oxidation the main aim has been to convert oxidisable species into carbon dioxide. Leachate originating in landfills is complex wastewater that could exert high environmental impact. This study aims to ...

Bottle deposit scheme plans unveiled
The UK government yesterday announced plans for a deposit return scheme for single-use drink containers in a bid to improve Britain’s floundering recycling rates. The scheme will be subject to a consultation later this year, and will look to emulate similar initiatives in Denmark, Sweden and Germany where recycling rates have risen up to 97%. UK consumers go through an estimated ...

Pick-up A Tyre Pyrolysis Plant And Start Recycling Business
Efforts to recycle today are ramping up, and those waste tires just can't reach the landfill. It's unfortunate whenever they do, specially when they may be recycled into resources which can be used for many different reasons. You obtain pyrolysis oil, carbon black and of course the steel that may be recycled from waste tyre pyrolysis plant. You may possibly not have got a use for all the ...

Effects of landfill leachate treatment on hepatopancreas of Armadillidium vulgare (Crustacea, Isopoda)
The major environmental impact to the landfill is emission of pollutants via the leachate and gas pathway.The hepatopancreas of the terrestrial isopod Armadillidium vulgare (Isopoda, Crustacea, Latreille 1804) takes an important role in bioaccumulation of contaminants, such as heavy metals. To evaluate the effects of landfill leachate treatment, two different approaches are here applied: 1) ...
