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...

Pharmaceutical residues can be removed from effluent using pine bark. Now, a Singapore-based research team is looking to pomegranate peel to remove 4-nitrophenol from water. The toxin is used when producing dyes, pesticides and analgesics. The pomegranate peel is converted to biochar at 600° before being ground to nanoparticles through ultrasound treatment. The particles’ surface attracts the nitrophenol, which...

Foliage can be used to make sustainable paper and packaging material. Similarly, a Swedish startup is using seagrass that has been washed ashore to manufacture environmentally-friendly yarn. Until now the plant, which is present in large quantities on beaches, has simply been discarded. A recent feasibility study has shown it can be made into yarn without the addition of...

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...

Waste wood isn’t just suitable as a sustainable polystyrene substitute. Now, a Finnish research team has created an alternative to petroleum-based resin using sawdust and straw. The presence of petroleum-based bonding agents makes it tricky to recycle composites, which are used for wind turbines, boats and RVs. The team extracted cellulose and hemicellulose from the waste wood, successfully developing...

Small villages can inspire innovation for the circular economy in cocoa production. Now an Oxford-based startup is working on a sustainable substitute to the cocoa bean. Sound familiar? This time rather than cell cultures the team is using the plant’s pod. First, the shells are chopped up and, using an age-old Japanese method, fermented with the help of fungi. The...

AI can find sustainable materials for the textile industry. A startup in England, meanwhile, is focusing on the circular economy and the power of nature to create non-toxic colouration technology. Plants owe their dazzling colour to crystals present in their cell walls, which reflect light differently depending on how they are arranged. The team extracts these crystals from the...

Spirit production provides furniture in Scotland. And as another Scottish startup discovered, whisky by-products can also help reduce overfishing. The team uses distillery waste water to manufacture Omega-3s. Wild fish are known to be a rich source of the fatty acids, but they actually acquire them by eating algae. The team used the waste from whisky distillation (including barley)...
