Most food-wrap films just act as a barrier to bacteria, but don’t actually kill the microbes. An experimental new film does exactly that, plus it changes color to show when food is spoiled. And what’s more, it’s made from avocado seeds.Continue Reading… Continue reading Color-changing food film uses avocado pits to kill germs and warn of spoilage
After sugarcane crops have been harvested, a great deal of fibrous stalk waste known as bagasse is left over. That substance has been incorporated into an eco-friendly building material called Sugarcrete, which recently won an international Climate Pos… Continue reading Sugar cane waste converted into concrete-beating Sugarcrete
Although various uses for post-harvest rice husk waste are being explored, the stuff is still usually either incinerated, dumped in landfills, or at best composted. Soon, however, rice husks may be combined with discarded newspapers to form eco-friendl… Continue reading Eco-friendly insulation would put rice husks and newspapers in our walls
A great deal of peel, pulp and stone waste is constantly being generated in the production of olive oil. And while that waste is often just dumped or incinerated, it could soon be used as a source of valuable antioxidants.Continue ReadingCategory: Good… Continue reading New technique harvests antioxidants from olive oil processing waste
A particularly impressive red alga has already shown great promise in dramatically reducing the alarming levels of methane gas produced by a cow’s enteric digestive system. Now, a team of scientists has moved from the animal’s belches to its tail end, … Continue reading Red alga added to cow poop slashes methane emissions by almost half
Farmers around the world regularly burn post-harvest crop waste, producing a significant amount of greenhouse gases and air pollution in the process. A new portable system, however, can be brought to farms to convert that waste into useful products.Con… Continue reading Towable tech travels to farms to convert waste into valuable products
You may have heard how the BPA (bisphenol A) in some food-packaging plastics has been linked to various health problems. Scientists are thus developing a more innocuous alternative, and it’s made from tomato waste which would otherwise be discarded.Con… Continue reading Tomato waste used for BPA-free food can coating
Solar stills provide a clever and simple means of purifying dirty or salty water, but they work at a rather slow rate. A new material has been shown to boost their performance, and it’s made from fruit waste which would otherwise be discarded.Continue … Continue reading Simple process converts fruit waste into water-purifying material
In the commercial production of apple juice and cider, large quantities of fibrous waste – known as pomace – is generated as a byproduct. And while that material is currently just discarded, new research suggests that it could be used to boost the heal… Continue reading Apple waste may find use in health-boosting chicken feed
Two years ago, we heard about a highly absorbant hydrogel made from upcycled pineapple leaves. Some of the scientists who developed that gel are now saying that the leaves could also be used to absorb harmful fats from recently consumed foods in our di… Continue reading Pineapple leaves may find use in fat-trapping ingestibles
