After two years of work, a panel of experts convened by the EU Commission's Directorate-General for Energy published guidelines for life cycle assessment of CCU technologies, i.e. technologies for carbon capture and utilisation. ifeu expert Nils Rettenmaier is one of the authors.
In the multi-year research Rapid Planning project, ifeu scientists Bernd Franke and Christin Zeitz coordinated the scientific activities of 11 German research partners, UN Habitat Nairobi and many Rwandan partners.
As part of the KEEKS project, a web app with 50 recipes was developed that is primarily aimed at school kitchens. ifeu has determined the environmental impact of all recipes. In addition to greenhouse gas emissions, the land, phosphate and water footprints of the recipes are also indicated.
In Germany today, we consume more goods and services than ever before. To date, there are only a few quantifying assessments of the effects of the associated material flows on the environment outside Germany. Above all, the consequences for biodiversity and ecosystem services are usually ignored. The "Konsumwende" project commissioned by the Federal Agency for Nature Conservation (BfN) aims to close this gap.
The mono-incineration of sewage sludge in a fluidized bed furnace is the technology of choice to implement the phosphorus recycling obligation specified in the Germany’s Sewage Sludge Ordinance 2017. During combustion, significant amounts of the greenhouse gas nitrous oxide are released due to the low temperatures in the furnace. If Germany's entire sewage sludge were completely incinerated, this could result in up to 800,000 tonnes of CO2 equivalent being emitted per year. ifeu is currently investigating possible reduction measures in several projects.
What potential of biogenic waste and residues is available to the energy system, and for what purpose should it be used? These questions were the focus of the UBA BioRest project carried out jointly with IZES and the Öko-Institut.
Biofuels have long been considered to play a key role in climate protection in transport. This role was significantly reduced by the discussion on food vs. fuel. At present, biofuels are again increasingly being brought into the discussion as a central solution in view of the difficulties in achieving climate protection targets in the transport sector.
The European Union's Horizon 2020 project MAGIC has reached a milestone by uploading a beta version of its Decision Support System for farmers and end users, showing marginal land and an overview of industrial crops suitable to be grown on this land.
