Field Study on the Efficiency of a Methane Degradation Layer Composed of Fine Fraction Soil from Landfill Mining Open
The main components of landfill gas are methane and carbon dioxide. Emissions of methane, a strong greenhouse gas, can be minimized by in situ oxidation in the bioactive cover layer. Typically, organic-rich porous materials such as compost…
Bioenergy Yields from Sequential Bioethanol and Biomethane Production: An Optimized Process Flow Open
This study investigates the potential of different stages of the bioethanol production process (pretreatment, hydrolysis, and distillation) for bioethanol and biomethane production, and studies the critical steps for the liquid and the sol…
Enhancing Bioenergy Yields from Sequential Bioethanol and Biomethane Production by Means of Solid–Liquid Separation of the Substrates Open
The production of second-generation ethanol using lignocellulosic feedstock is crucial in order to be able to meet the increasing fuel demands by the transportation sector. However, the technology still needs to overcome several bottleneck…
Bod sensor for wastewater analysis- design and calibration methods Open
Water quality monitoring is an important aspect of water management concerning to thepollution control. The removal of biodegradable organic substances is a very importantaspect of evaluation the treatment efficiency in a wastewater treatm…
Combined Effects of Test Media and Dietary Algae on the Toxicity of CuO and ZnO Nanoparticles to Freshwater Microcrustaceans Daphnia magna and Heterocypris incongruens: Food for Thought Open
The chemical composition of the test medium as well as the presence of algae (microcrustaceans’ food) affects the bioavailability and thus the toxicity of metal nanoparticles (NP) to freshwater microcrustaceans. This study evaluated the ef…
Environmental aspects of waste glass storage Open
There are only few researches about possible environmental impact of waste glass, mostly focusing on crystal glass industry waste and not on packaging glass waste. The aim of the current research was to examine properties of stored waste g…
Fractionation of Pb and Cu in the fine fraction (<10 mm) of waste excavated from a municipal landfill Open
The fractionation of metals in the fine fraction (<10 mm) of excavated waste from an Estonian landfill was carried out to evaluate the metal (Pb and Cu) contents and their potential towards not only mobility but also possibilities of recov…
Assessment of biological activity of fine fraction from Högbytorp landfill by oxygen consumption measurement Open
The objective of this study was to estimate the biological activity of fine fraction excavated from the Ragn-Sells AB landfill site at Högbytorp (40 km north-west of Stockholm, Sweden). For this purpose cumulative oxygen consumption (respi…
Speciation of metals in the fine fracion of solid waste from an excavated landfill Open
In this current study, speciation of metals in the fine fraction (<10 mm) of excavated solid waste from an Estonian landfill was performed in order to evaluate metal contents and their potential mobility and bioavailability. The fine fract…
A study on methane degradation layer extracted from landfill mining Open
Due to the harmful effect on the environment, landfill gas has to be collected and processed. One possible solution would be covering the landfill with a bioactive layer, where methane gas is oxidized. The aim of this research is to study …
Leaching characteristics of the fine fraction from an excavated landfill: physico-chemical characterization Open
This investigation was focused on the physico-chemical characterization of the leachate generated by the fine fraction (<10 mm) of excavated waste from full-scale landfill mining project. The samples were taken in the Kudjape Landfill, Saa…
Experiences of three landfill mining projects in the baltic sea area: with focus on machinery for material recovery Open
