A fashion collection made from the remains of grapes from the wine industry and plastic made from chicken feathers are two new twists on the practice of making new products from waste, and a growing demand for sustainability from consumers mean there could be a ready market for this type of innovation.
Food waste isn’t just the result of groceries that have gone off or uneaten meals. As food is processed for consumption, huge amounts of waste are generated. The European poultry industry, for example, generated about 3.1 million tons of discarded feathers in 2014. And during wine production, around 25% of the weight of grapes, such as the skins and seeds, are wasted.
These byproducts could soon be given a second life, as scientists work out how to transform them into new materials.
