Annual Report 2012 - Institute of Resource Ecology08 May 2013 (has links) (PDF)
The Institute of Resource Ecology (IRE) is one of the currently eight institutes of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The research activities are fully integrated into the program “Nuclear Safety Research” of the Helmholtz Association and focused on the topics “Safety of Nuclear Waste Disposal” and “Safety Research for Nuclear Reactors”. With the integration of the division of “Reactor Safety” from the former “Institute of Safety Research” nuclear research at HZDR is now mainly concentrated within this institute.
In addition, various activities have been started investigating chemical and environmental aspects of processing and recycling of strategic metals, namely rare earth elements. Here, a knowledge transfer from the nuclear to the non-nuclear community, branching thermodynamics and spectroscopy, has been established. This also strengthens links to the recently established “Helmholtz-Institute Freiberg for Resource Technology”.

Annual Report 2013 - Institute of Resource Ecology15 May 2014 (has links) (PDF)
The Institute of Resource Ecology (IRE) ISone of the eight institutes of the Helmholtz-Zentrum Dresden-Rossendorf (HZDR). The Research activities are mainly integrated into the program “Nuclear Safety Research (NUSAFE)” of the Helmholtz Association (HGF) and focused on the topics “Safety of Nuclear Waste Disposal” and “Safety Research for Nuclear Reactors”.
Additionally, various activities have been started investigating chemical and environmental aspects of processing and recycling of strategic metals, namely rare earth elements. These activities are located in the HGF program “Energy Efficiency, Materials and Resources (EMR)”. Both programs, and therefore all work which is done at IRE, belong to the research sector “Energy” of the HGF.
The research objectives are the protection of humans and the environment from hazards caused by pollutants resulting from technical processes that produce energy and raw materials. Treating technology and ecology as a unity is the major scientific challenge in assuring the safety of technical processes and gaining their public acceptance. Namely, we investigate the ecological risks exerted by radioactive and non-radioactive metals in the context of nuclear waste disposal, the production of energy in nuclear power plants and in processes along the value chain of metalliferous raw materials. A common goal is to generate better understanding about the dominating processes essential for metal mobilization and immobilization on the molecular level. This in turn enables us to assess the macroscopic phenomena, including models, codes and data for predictive calculations, which determine the transport and distribution of contaminants in the environment.

The Journey of Resources : Archaeobotanical analysis of late Iron Age and medieval Sigtuna, SwedenPettersson, Siri January 2019 (has links)
Traditional agriculture has played an important role in shaping the landscape for thousands of years. Agriculture and interactions between humans and their surroundings have changed since the beginning of historic time in Sweden, approximately 1000 years ago. Through botanical macrofossil analysis of plant remnants found in an urban ditch in Sigtuna, Sweden, I examine which natural landscapes the town’s inhabitants may have interacted with in terms of resource collection in the beginning of the Medieval period. The results showed indications of predominantly nutritious wet grassland habitats, but also dry grassland and forests, as well as remnants of urban and cultivated species. The species indicate that the resources may have been used as winter fodder for animals, but possibly also as sustenance for humans as well as building material. The results indicated little change over time, regarding which landscape types were interacted with, but there were possible indications of a decrease in grassland resource collection in the youngest sample from 1150 A.D. Further research is needed to understand the indication. The material indicates that the Cyperaceae family will be instrumental in continuing this research.
