“…The same objective of strengthening cement by creating a mixture was considered using ash obtained from the traditional burning of hazelnut shells. Contrary to what was described by Tareq Noaman et al [117], the different composition of the ash affected the compressive strength of the material in an inversely proportional manner: increasing the ash content over 5% in weight led to a decrease in the strength of the material. Cement blended with ash reduced the pose time significantly up to 96% of the time [114].…”

“…Hazelnut shells as reinforcing agents, as already observed for almond shells, were tested mixed together with cement. The obtained cement composite exhibited improved properties, in particular considering the compressive strength and hardness when added proportionally to the amount of ground shells used, probably due to interactions occurring among the particles (maximum enhancement at 2.5% of shells addition in weight) [117]. The same objective of strengthening cement by creating a mixture was considered using ash obtained from the traditional burning of hazelnut shells.…”

Nuts consumption has increased significantly in the last 10 years, especially driven by the stimulated awareness of their possible beneficial health effects. Increased nuts consumption is linked to an obvious accumulation of by-products and waste. With the view of the circular economy, the aim of this review is to analyse the recent and innovative approaches able to valorise the by-products derived from almonds and hazelnuts, two important nut products of the Italian scene, with historical and traditional importance. The most important solutions are concerned with reuse of almond hull, shell, skin, oil cake, and hazelnut shell; skin and oil cake are often considered waste or by-products. Many interesting implications in the feed and food sectors have been detected in the last ten years, aimed at designing innovative materials developed from by-products and extraction of bioactive molecules for different purposes. The perspective chosen to discuss the topic is related to the sustainability of these processes, in terms of both the environment and economy. The circular economy supports a zero-waste approach, which should not also be meant as a zero-cost process in terms of the level of technology that has been partially developed.
