“…sativa is an economically important resource in Europe, mainly on the northern shores of the Mediterranean basin, having a key role in different production chains (timber, our, honey, and tannins) [24]. Based on current and emerging uses of tannin and the strong market demand, process improvements and the availability of methods enabling also limited-scale productions by local stakeholders in rural and mountainous areas could be environmentally, economically and socially bene cial [25].…”

Tannins, extracted from various plant sources, are worldwide commodities used in several different fields, including leather manufacturing and the production of bio-based adhesives, with emerging use in technical, environmental, food and feed sectors, pharmacology. Due to increasing market demand, few emerging techniques were proposed besides the usual hot water extraction usually performed under pressurized conditions. For the first time, hydrodynamic cavitation, an emerging and straightforwardly scalable green extraction technique, was applied to the extraction of tannins from chestnut wood waste in water only and at room pressure, without any pretreatment of the raw material. Promising performances were shown based on tests carried out from room temperature up to 100°C. Extraction rates close to 300 mg of tannin per gram of chestnut wood material (dry basis) were observed, as well as high levels of the antioxidant activity of the obtained extract (IC50 about 10 µg of chestnut wood waste, or 2.45 µg of extracted tannin, per mL of solution). Specific energy consumption was less than 80 Wh per mg of tannin extracted from 1 g of chestnut wood material. The proposed technique would be suitable for both small-scale and industrial extraction facilities.

“…Tannin is the name given to a mixture of high molecular weight biophenols extracted from certain woods and bark and increasingly used for widely different applications, including as an environmentally friendly agrochemical. 28 Due to an expensive and energy-demanding production process, the current annual production of commercial tannins amounts to about 230,000 tonnes. Tannin, however, has a high-value chemical application as a building block in the preparation of adhesives and resins.…”

The educational gap for which science is not taught to managers, and management is not taught to scientists, is a significant obstacle to a company's success also in the bioeconomy field. Companies worldwide eagerly seek for new managers, researchers and technologists owning new knowledge and skills in topics spanning from circular production processes through new energy technologies and green chemistry. Most employers, however, have difficulty recruiting qualified professionals due to the shortage of qualified professionals. This shortage includes bioeconomy managers capable to successfully lead bioeconomy companies. Shaping the managers of successful bioeconomy companies, we argue in this study, requires to transfer a closer understanding of the nature of bioeconomy companies and their competitive landscape, as well as identifying the main guiding principles for managing these organizations.
