Radionuclides and soil properties as indicators of glacier retreat in a recently deglaciated permafrost environment of the Maritime Antarctica Universiteit Gent
Amplicon and shotgun metagenomic sequencing indicates that microbial ecosystems present in cheese brines reflect environmental inoculation during the cheese production process Vrije Universiteit Brussel
The taxonomic diversity of the microbial communities associated with stable 30-y old cheese brines from an artisan and large-scale cheese producer located in Flanders, Belgium, was investigated cultureindependently. High-throughput amplicon and shotgun metagenomic sequencing revealed species of Tetragenococcus, Chromohalobacter, and Halanaerobium as the most abundant ones in both brines. Debaryomyces was the only yeast genus detected. All these ...
Malachite, an indicator of major Pliocene Cu remobilization in a karstic environment (Katanga, Democratic Republic of Congo) KU Leuven
Malachite [Cu3(OH)2(CO3)] is a common mineral in the Central African Copperbelt, where it constitutes a high-grade (~57% Cu) copper ore and is exploited industrially and by artisanal miners. The genesis of this supergene ore in Katanga has yet received little attention. Here we focus on the genetic processes giving rise to this regionally important mineral. Malachite is secondary to primary copper sulfides, which indicates that it ultimately ...
A palaeoclimatic record from the Ledo-Paniselian Aquifer in Belgium : indications for groundwater recharge and flow in a periglacial environment Universiteit Gent
Understanding the mechanisms of groundwater recharge and flow in periglacial environments remains enigmatic. Methane releases from melting permafrost in a warming world are a hot topic in contemporary climate research. Noble gas analyses have been proposed to study methane-driven degassing in lakes as well as in permafrost terrains. The Ledo-Paniselian aquifer is shown to provide an analogue for such processes, from the last period of global ...
A review of sustainability indicators for biobased chemicals Universiteit Hasselt Universiteit Antwerpen
Companies dealing with chemical products have to cope with large amounts of waste and environmental risk due to the use and production of toxic substances. Against this background, increasing attention is being paid to “green chemistry” and the translation of this concept into biobased chemicals. Given the multitude of economic, environmental and societal impacts that the production and use of biobased chemicals have on sustainability, ...
Circular economy indicators : what do they measure? Universiteit Gent KU Leuven
Circular Economy (CE) is a growing topic, especially in the European Union, that promotes the responsible and cyclical use of resources possibly contributing to sustainable development. CE is an umbrella concept incorporating different meanings. Despite the unclear concept, CE is turned into defined action plans supported by specific indicators. To understand what indicators used in CE measure specifically, we propose a classification framework ...
Sustainability indicators for biobased chemicals: A Delphi study using Multi- Criteria Decision Analysis Universiteit Hasselt Universiteit Antwerpen
Biobased chemistry has gained interest and has the potential to tackle some of the sustainability challenges the chemical industry must endure. Sustainability impacts need to be evaluated and monitored to highlight the advantages and pitfalls of different biobased routes over the entire product life cycle. This study aims for expert consensus concerning indicators needed and preferred for sustainability analysis of biobased chemicals in Europe. ...
The Importance of comfort indicators in home renovations - a merger of energy efficiency and universal design Universiteit Hasselt
Literature, governmental and policy goals reveal a need to merge the, until now separately considered, concepts of Universal Design (UD) and Energy Efficiency (EE) in home renovations. Using the concept of Comfort from the perspective of homeowners, as a framework that unifies UD and EE, a list of 21 comfort indicators was developed. This paper discusses a survey undertaken with 145 homeowners to check whether these comfort indicators were ...
Advantages and limitations of exergy indicators to assess sustainability of bioenergy and biobased materials Universiteit Hasselt Universiteit Antwerpen
Innovative bioenergy projects show a growing diversity in biomass pathways, transformation technologies and end-products, leading to complex new processes. Existing energy-based indicators are not designed to include multiple impacts and are too constrained to assess the sustainability of these processes. Alternatively, indicators based on exergy, a measure of “qualitative energy”, could allow a more holistic view. Exergy is increasingly applied ...
