Cultivated agents

Sustainable background music makes most things easier. Even cleaning. And it could be better yet. A Belgian startup is using spent cooking oil and food waste to produce environmentally-friendly cleaning products. With the help of yeast organisms isolated from bumble bee honey, potato peel and vegetable scraps from the supermarket are fermented in a patented process. The resulting biosurfactants...

Uniform reuse

Beer can be brewed from industrial wastewater. Now a research team from Singapore is using the wastewater from soybean production to create sustainable feed for fish farming. Usually, feed is made from wild-caught fish (sometimes very wild-caught indeed!). The team cultivated a single-cell protein in a bioreactor over four months at 30°C using the protein-rich wastewater and the micro-organisms...

Salvaging principle

In future, circuit boards for PCs could be made from mushrooms. Now, an EU-financed research team is attempting something even more daring. They are building components for mobile machines from edible materials. People in remote places could be given drones for dessert while other drones deliver vaccinations to endangered animals. Work is already underway to create a sprayable sensor...

Large serving

Insoles with fungal spores help prevent bacteria and foot diseases. Now a Canadian-based startup is also using mushroom spores - to produce large quantities of protein-rich, plant-based food. First step: extract the sugar from agricultural waste. The sugar serves as nourishment for a teaspoonful of spores from different edible mushrooms, which are then fermented in large steel tanks. Next,...

Positional disclosure

Monitoring the fish population could prevent overfishing. Where industrial fishing is concerned, however, there is still room for improvement. Using satellite images and vessel GPS trackers, a US-based non-profit organisation collated 2 million gigabytes of data spanning the years 2017-2021. Data harnessed, in turn, to train an artificial intelligence that could map vessel activities and offshore infrastructure such as...

Stylish search

Deciding on a foreign university is easier with first-hand information. Those wishing to practise a sustainable lifestyle away from home, however, often spend a long time looking for the right shops and restaurants. Now a Munich-based startup is making the process easier thanks to its new digital platform. It contains an index of firms and businesses that offer sustainable...

Minimising mix

Waste from breweries is a breeding ground for sustainable livestock feed. But the methane produced by these animals during the digestive process has a significant impact on the environment. For a female-led startup in Hawaii, however, the solution lies in a particular species of red algae called Asparagopsis taxiformis (instead of kangaroo babies). According to tests conducted on livestock,...

Continental score

Image analysis can find hidden ruins or save elephants’ lives. But that’s just the start. A female-led startup in Nairobi is using satellite images and artificial intelligence to strengthen the continent’s agriculture industry. After all, around 60% of sub-saharan Africa’s jobs are dependent on it - most of them smallholders significantly impacted by climate change. The machine-based image analysis...
