Organisationseinheit der BAM
Since it was realized that sites contaminated with metals and radionuclides needed treatment, various remediation methods have been and are being developed. Depending on the size of the contaminated site and urgency of intervention, conventional or recently introduced techniques have been used. Conventional techniques include excavation and removal for treatment of soil and contaminants, or the so-called “pump-and-treat” method, in which contaminated groundwater is removed from the ground by pumping and treated in a treatment plant on the surface. It has the advantage of using proven techniques and is easy to control, and the treated groundwater can be reinjected into the ground or discharged in rivers or lakes. Novel methods include permeable reactive barriers, biomineralization, and electrokinetic remediation.
The European building sector is moving towards more complex and high-tech building approaches. While focusing on energy efficiency, aspects e.g. occupant health, sustainability and life cycle costing are often neglected. This study highlights the potential of earthen plasters in combination with natural ventilation for low-tech solutions.
The EU funded project [H]house established the outstanding performance of earthen materials in light of hygrothermal and air purifying properties, which were further supported by experimental data from monitoring of naturally ventilated pilot buildings in Berlin. Additionally, [H]house demonstrated through LCC an increased cost efficiency of earth based low-tech solutions in comparison to conventional constructions relying on mechanical ventilation.
Waste, Evaluation Methods
(2019)
It is difficult to decide which waste management system fulfills best predefined sustainability goals such as maximum materials and energy recovery, least environmental impact, and lowest societal cost. Such decisions are based on many parameters. However, several evaluation methods exist with different scope and output, and the application of one or more evaluation methods provides an objective comparison of alternatives.
