Coffee grounds have much to offer. So too waste from fruit, vegetables or nuts, as shown by the female founder of an American startup. Using specially developed refining technology, waste from agricultural farms and food plants is put to good use. Key to the enterprise is the polarity of water, along with pressure and temperature changes. The process enables...

Some cosmetic containers can be composted at home. Following a similar idea, a Spanish startup has developed an ultra-thin, biodegradable packaging film from plant-based starch, which is certified for home composting. Despite being only 7 micrometres thick, the thermoplastic substitute for fossil-based film is mechanically tearproof at 114N/mm2 and manufacturing costs are comparable to traditional polyethylene products. A patent...

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...

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...

Rapidly spreading algae makes construction materials more sustainable. High numbers of shore crabs likewise disrupt the maritime ecosystem. Which is why a Danish startup is collecting the invasive beach- and ocean-dwellers using crab baskets or passive fishing nets. Once caught, crab flesh and shell are processed separately into flour and used as animal- or fish-feed supplements. Crab meal powder...
