There are now 12 new bicycle service stations on the biomedical campus of the University Hospital Cologne, which can be used free of charge and are available to all cyclists on campus around the clock. Further information and a map of the bicycle service stations can be found here.

In future, employees will have the opportunity to test one of 13 bicycles free of charge for a week. There is a choice of folding bikes, city bikes and cargo bikes. The majority of these are e-bikes. The bikes can be booked quickly and easily via an app. The bikes will then be issued and returned centrally at the workshop building on the university hospital campus on presentation of an ID card. The bike pool is expected to go into operation next spring.

Maximum for the climate: From August 7, 2023, the cafeteria of the University Hospital Cologne will completely dispense with disposable tableware and will exclusively use the multi-use tableware of the Cologne-based company Vytal for food and beverages that are taken "to go". In doing so, the subsidiary UK Catering (UKC) wants to take the next step toward responsible employee catering of the future. "By completely switching to the reusable system, we save more than four tons of disposable tableware annually in the cafeteria area, which is a lot of waste. In this way, we want to make our contribution to the maximum for climate campaign of the University Hospital Cologne," explains Thomas Schnell, head of guest catering. "With Vytal as our partner, we are not only relying on a company from the region, but on Europe's largest digital provider in the reusable systems segment."

To use the system and continue taking your food home, it doesn't take much: download the Vytal app, register, scan the QR code on the containers handed out and show it at the checkout. Until now, a rental fee of 0.20 euros per filling was still due, but this will be completely eliminated with the complete changeover at the beginning of August. The container can then be returned free of charge within 14 days via one of the numerous Vytal drop-off stations. These can be found on the campus of the University Hospital Cologne in the kiosks of the UKC as well as in the entrance area of the cafeteria or at 5,000 other partners throughout Europe. Only if the fourteen-day period is exceeded will a fee be charged to the user.

Anyone who now thinks that they can use their Tupperware without any problems will unfortunately be disappointed. For hygienic reasons, filling food and beverages into other containers is unfortunately prohibited.

• that scientists in the U.S. found that rain floods protected national parks with 1,000 tons of microplastics each year – the equivalent of more than 120 million plastic bottles. Microplastic pollution has reached every part of the globe, from the top of Mount Everest to the deepest oceans. It is already known that people ingest and inhale the tiny particles through food and water. Recent studies show that microplastic pollution can even be found in human placenta!
• that fifty years ago this month, meteorologist John Sawyer published a brief but prescient article in Nature. In it, he summarized what was known about the role of carbon dioxide in the greenhouse effect and made one of the first predictions about future global warming: that temperatures would rise by 0.6°C by the end of the twentieth century.
• that 30% of biodiversity loss is related to global trade. This came out of an analysis that linked 25,000 threatened species to 5 billion supply chains and consumption of goods such as coffee, tea, sugar, textiles, and fish (Lenzen, M. et al. Nature 486, 109-112, 2012).

Article: Civil disobedience by scientists helps demand urgent climate action

The article by Capstick, Thierry, Cox, Berglund, Westlake and Steinberger argues that civil disobedience by scientists is justified to demand urgent climate action. He emphasizes that traditional methods of research and communication may be failing in the face of the climate crisis and calls for new ways of acting. Civil disobedience by scientists is seen as an effective strategy to communicate the urgency of the climate crisis and bring about change. It is argued that the trustworthiness of scientists allows them to play an important role in social movements and that the climate crisis fulfills the conditions for civil disobedience.

Article: How sustainable change can boost labs' budgets

The article highlights how labs can reduce energy costs and increase research budgets through green measures such as recycling chemicals and equipment. One example is Hopi Hoekstra's lab at Harvard University, which saved around $10,000 by winning a competition to reduce energy consumption and use freezers more efficiently. Such initiatives not only help to protect the environment, but also provide additional funding for scientific purposes.

Article: Scientists call for reduction of plastic waste in the lab

The authors of the article call for measures to reduce the five and a half million tons of plastic produced worldwide in the course of scientific research. They estimate that life science research is responsible for 1.8 percent of global plastic production, the equivalent of 67 cruise ships per year. The authors emphasize that the research community and funding agencies should put environmental awareness above the cost of research and take action to reduce single-use plastic waste. They suggest that funders could encourage more environmentally friendly practices by funding laboratory rinsing and recycling facilities and make this a requirement in the application process.

Article: Motion and sash height alarms (MASH) for efficient use of the fume cupboard in the laboratory

Article: Active monitoring of fume hoods to save energy

The article looks at the effectiveness of real-time audio feedback to alert fume hood users when the sash is open and the hood is not in use. This method was found to result in significant energy savings. Users reported changes in behavior after the alarm was installed. The device uses a combination of image processing and motion detection to monitor the status of the hood and trigger an alarm when required. The cost of the device and its manufacture is also explained, and it is noted that the device could also be used for other applications such as monitoring light, water or waste streams.

Behavior change by design: A fume hood shutter experiment

This article reports on a laboratory exhaust ventilation program that considers laboratory safety and sustainability. The study took place on the campus of a large research university and involved two interdisciplinary science buildings. The intervention consisted of placing a sticker on the fume hoods and then providing feedback based on the closure data. The intervention led to a significant improvement in the closing behavior of the fume hoods. The long-term effects of the intervention showed that the sticker was still effective one year later. However, it was found that the feedback played a crucial role in the change in behavior.

Article: Motion and sash height alarms (MASH) for efficient use of the fume cupboard in the laboratory

The article describes a study on the efficient use of fume hoods in laboratories. The researchers developed a "Motion and Sash Height" (MASH) alarm that notifies lab users when a fume hood is open and unused. The installation of these alarms led to a significant reduction in average sash height by over 75%. The financial savings per year per fume hood by using the MASH alarm amounted to approximately 1159 US dollars. The authors suggest further improving the alarm to become even more cost-effective and introducing additional features such as sash height monitoring. Overall, the MASH alarm is an effective and cost-efficient solution for reducing energy consumption in laboratories.

Climate protection in hospitals: clinics reduce emissions

The KLIK green project has trained climate managers in around 250 hospitals and rehabilitation clinics to implement various measures to reduce greenhouse gas emissions. The initiative is expected to have saved 200,000 tons of CO2Ä, with 187 climate managers implementing 1,640 measures. These measures range from energy-efficient lighting to switching to renewable energy and changing diets. Some of the measures implemented required investment, while others were cost-effective or even cost-neutral. The participants, including doctors, nurses and administrative staff, have shown that active climate protection in the healthcare sector is possible and can even result in financial savings.
