When you think of fuel cells, you don't necessarily picture bacteria. However, microorganisms also need energy for their metabolism and obtain it through electrochemical processes. Excess electrons are released into the environment by the unicellular organisms. Biotechnologists want to take advantage of this fact to drive microbial fuel cells. The project "Textile Carbon Electrodes for Microbial Fuel Cells" (TexKoMBZ) has developed a special anode that makes future industrial-scale applications seem realistic.
Reducing allergens in food
Many people suffer from food allergies. According to estimates by the German Allergy and Asthma Association (DAAB), around six million children and adults are affected in Germany alone. Peanut allergy is particularly widespread. So far, allergy sufferers have had to do without allergy-causing foods such as peanuts or mustard, as the condition cannot yet be cured.
In pursuit of naturally healthy flavour
Pre-processed food needs to become healthier, this is the mission of practically all producers. Sugar promotes obesity, salt cardiovascular diseases. When it comes to reducing the amount of these ingredients in a product, however, manufacturers' primary method has been to lower the recommended portion size. Tests with alternative, healthier formulations have shown that products that contain less sugar or salt than consumers are used to rarely meet their taste expectations - and fail to capture the market.
Mussel style superglue
They sit tight on the seabed, and even the waves hitting the coast can’t harm them – mussels. The secret of their resilience lies in their feet: The shellfish’s feet produce a protein that sticks underwater like no other substance. Be it stone, metal, or plastic: the mussel adhesive sticks extremely well to almost any surface.
Biotechnological upcycling for plastic waste
Germany has a recycling problem, even if it appears to be different at first glance. While the Federal Environment Agency reported a recycling rate of 99.4% for 2017, slightly more than half of the 6.15 million tonnes of collected plastic waste was thermally recycled, i.e. used to generate heat in waste incineration plants, cement works or power stations. Material recycling amounted to only 2.87 million tonnes (46.7%). This process conserves around three times as much of the energy contained in the plastic as can be used thermally by burning it.
Social inequalities in the bioeconomy
"No action without reaction" is a phrase that implies that every action has consequences. The shift from a petroleum-based economy to a sustainable, bio-based one entails multi-faceted changes - on a global scale. Sociologist Maria Backhouse is convinced that "no social changes, including technological developments, take place in a vacuum", but are "permeated by social inequalities from the global to the local level".
How climate change impacts fish species
Herring, pike-perch or salmon: fish is among the top healthy foods. The demand has been high for years. According to the Federal Statistical Office, in 2018 each person in Germany consumed about 13.7 kilograms. But Myron Peck knows that climate change will dictate which fish ends up on the plate in the future.
Bioeconomy as a global trend
German Federal Research Minister Anja Karliczek opened conference event with a welcome address together with the GBS2020 organizing International Advisory Council on Global Bioeconomy (IACGB), which published a summit communiqué, making it available for a broad audience to discuss. Addressing the Summit today, the German Federal Minister for Food and Agriculture Julia Klöckner emphasized the key role of agriculture and the food system in the sustainable bioeconomy.
Insulated packaging
Before Advent, Deutsche Post had already broken its previous record of 1.58 billion parcels delivered: online shopping and food deliveries are in greater demand than ever - especially in times of Corona. This results in huge amounts of packaging waste. Therefore, Landpack relies on straw instead of polystyrene.
Silage films made from biopolymers
After the harvest, straw bales wrapped in white plastic film dominate the landscape of many fields. In these so-called silage bales, fodder crops such as corn are turned into food for cattle through lactic acid fermentation. But the films used for this purpose are anything but environmentally friendly. They are made of conventional plastic and have been shown to leave traces of microplastics in the soil. "In addition - and this is particularly regrettable - they have so far been purely disposable and thus bad for the eco-balance," explains Isabell Kleiber.
