The countries analysed were Denmark, Germany, France, the UK, Italy, the Netherlands, Poland, Romania, Sweden and Spain. More than half of the agricultural land in these countries is currently used for the production of meat and dairy products. Only 20% of agricultural land is used to grow crops that feed the population.

DATI innovation communities
Bringing more good ideas into application and thus to companies and people: As a new component of its transfer and innovation promotion programme, the Federal Government intends to promote social and technological innovations in the future by setting up the German Agency for Transfer and Innovation (DATI). As an innovation agency, DATI will be based in Erfurt.
Deep-sea enzyme masters PET degradation
Deep in the sea, there is apparently another biological solution to the global plastic waste problem: researchers from the universities of Kiel, Hamburg and Düsseldorf have discovered an enzyme in a microorganism from the deep sea that breaks down the plastic polyethylene terephthalate, or PET for short. PET is the main component of many plastic bottles.
Wastewater treatment with magnetotactic bacteria
A problem with many former mines is that their floodwater is usually contaminated with heavy metals, in the case of uranium mines, for example, with uranium. Environmental biotechnology has long been developing approaches to filter out these heavy metals with the help of microorganisms. Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have now discovered a promising bacterium for this purpose.
Biodiesel from sewage sludge
Electromobility is experiencing rapid growth. However, important issues relating to the charging infrastructure for electric cars remain unresolved. Further, there will continue to be areas of application in the mobility sector for which battery-electric solutions are less suitable. Synthetic, CO2-neutral fuels could cover these areas. A team of researchers at Coburg University of Applied Sciences is now investigating another approach to producing biogenic, climate-friendly diesel.
"The ecological footprint must incorporate all climate factors"
Emissions of the greenhouse gas CO2 are responsible for most of global warming. However, land and oceans currently absorb only about half of these emissions. So-called CO2 removal measures such as renaturation of peatlands, coal phase-out, energy-efficient building refurbishment and climate-friendly mobility are intended to counteract global warming. But are these measures really enough to rebalance carbon sources and sinks? No - says Nadine Mengis.
Climate-friendly cement from mining sludge
It's a question of perspective: Up to now, many companies have regarded mining sludge and mine water as pollutant-containing waste because they contain cadmium and arsenic, for example. But a research team from the TU Bergakademie Freiberg sees things differently. In a pilot project, the experts have developed a process that removes the pollutants from sludge and water, extracts valuable substances and uses the rest as raw material for a more climate-friendly production of cement and concrete alternatives.
Estimating the environmental impact of new bio-products
"Green chemistry" - i.e., environmentally friendly, sustainable and biobased chemistry - is defined by twelve principles. Paul Anastas and John C. Warner established them in 1998. While many of their principles are now widely taken into account when the industry develops new substances, a research team led by the Goethe University in Frankfurt believes that one principle has so far been neglected: the reduction of environmental toxicity.
WWF and AWI (2022): Impacts of plastic pollution in the oceans on marine species, biodiversity and ecosystems
For the meta-study, commissioned by WWF and carried out by the Alfred Wegener Institute (AWI), 2,592 studies were evaluated that were conducted between 1960 and 2019.
