Tomato waste can protect tinned food. Meanwhile another Italian startup is aiming to extend the shelf life of fruit and vegetables - using waste from liquorice production. Certain materials in the ‘sweet root’ are effective against bacteria, viruses and fungal spores. In a patented process, root hairs from the plant are extracted then converted into nanoparticles, which are used...

Waste from beer production can be used as a leather alternative. If breweries aren’t inventing new types of beer, then maintaining the quality of hops is vital. Hops, after all, is what gives beer its distinctive taste. With climate change impacting consistent plant properties, a female-founded startup in Spain is mitigating the risk by growing hops vertically in 10m...

Some have turned to chickpeas as a coffee alternative. An invigorating espresso, however, remains hard to replace. Now, an Australian research team has come up with the next best thing: espresso prepared using 75% less energy than before. The trick lies in the use of ultrasound waves rather than boiling water. A transducer attached to the side of the...

Hemispherical solar cells produce more electricity. Solar modules installed on facades or outside windows also allow for increased energy generation, albeit their weight is a drawback. The gossamer thin, translucent perovskite solar cells made by a Singapore research team, however, could generate hundreds of megawatt hours per year on large buildings. The fineness of the parts was achieved through...

Pancreatic cancer can be arrested by vitamin D, which is also vital for the function of human immune systems, as well as for bone, muscle and gum development. Yet one in six are vitamin D deficient. To cover the growing demand for additional vitamin D supplements, a French startup is using biosynthesis to produce vitamin D3-oil from mealworms. The...

A robot removes algae from ships’ hulls autonomously. Now, a Norwegian startup is using automated technology to combat mildew and fungal mould on grapevines. Here, too, there is no need for chemicals, as the electrically-powered robot doesn’t employ oil or sulphur, but soft UV-C light. The latter specifically breaks up the DNA of pests and viruses while protecting the...

A membrane filters wastewater and runs on its own electricity. Inspiration, perhaps, for a US research team, which has created a solar panel from black metal to make seawater drinkable without pre-treatment. Key here: special surface treatment of the metal. Tiny laser-cut grooves make the metal permeable to water without affecting its ability to absorb sunlight. Through the capillary...

Coffee grounds are a versatile thing: used in everything from sustainable concrete to glasses frames, even offering natural oils for cosmetics. But as a cocoa alternative? It might sound far-fetched, but that’s exactly what a USA-based startup is trying to achieve. The logic is simple enough: from a taste perspective there are similarities between coffee and cocoa. First the...
