Utilisation of MSWI bottom ash as sub-base in road construction: first results from a large-scale test site

Abstract

The preferred management option for municipal solid waste incinerator (MSWI) bottom ash in Denmark is utilisation rather than landfilling, but the current environmental quality criteria for bottom ash to be utilised in bulk quantities are rather strict. To evaluate the impact and risk assessments, upon which those criteria are based, a large-scale test site has been established. Three different MSWI bottom ashes have been used as sub-base in six test units ranging from 100 to 200 m2 with top covers of asphalt, flagstones and pebbles, respectively. All units, except one, are equipped with bottom liners and leachate collection equipment. The test site provides information on the leachate quality and quantity as a function of time under different conditions and on the flow pattern in asphalt and flagstone covered roads and squares with MSWI bottom ash sub-base. In addition, the leaching behaviour of the bottom ashes has been studied in the laboratory. The test site was established in October 2002 and the project is still ongoing. Water balance results indicate that the water flow distribution is strongly influenced by lateral flow on or in the upper part of the bottom ash layer and possibly by preferential flow. Comparisons betwee...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
