Agricultural co-product management: An LCA perspective on the use of safflower oilcake from bio-oil production in Umbria region, Italy
No full textThis work evaluates the impact of cultivating Safflower (Carthamus tinctorius L.) in marginal lands of the Umbrian territory (Italy) to produce oil. The analysis considers the entire production process, aiming to understand which are the most impacting factors. In particular, the work assesses the environmental savings deriving from the reuse of the main by-product of the oil extraction process, i.e. the cake, for animal feed purposes. The evaluation was carried out by means of a cradle-to-gate LCA. The results show that the greatest impacts are due to the crop fertilization. However, such an impact is almost completely compensated by the use of the cake in feed production

Pomegranate, bud-derivatives, and lavender: three example of eco-sustainable industrial supply chains
No full textThe development of sustainable solutions for the management of agricultural and food waste is currently one of the main challenges of our society. In developing countries, agriculture and food processing generate large amounts of waste and by-products, with a significant environmental, economic, and social impact. On the other hand, many of these products could represent a potential source of valuable compounds (i.e., bioactive compounds, macronutrients, micronutrients, and dietary fibers)1.
Pomegranate (Punica granatum) crop is nowadays spread all over the world for its high longevity, drought and salinity resistance and adaptability to different climatic conditions. Pomegranate juice is the main industrial product obtained from this fruit, and the by-products of this processing represent an expensive disposal problem but also a promising source of bioactive compounds to be exploited. Particularly, ellagic acid (EA), in its free form or in the form of ellagitannins (ETs), is considered the main phenolic compound responsible for the numerous health properties of pomegranate and is mainly concentrated in the by-products with respect to the juice (both external peels and internal edible marcs)2.
Bud-derivatives and lavender represent two supply chains studied in the Finnover "Innovative strategies for the development of cross border green supply chains" project, namely a cross-border Italy/France EU Interreg Alcotra project (2017-2021). The aims of this research project were the innovation and the sustainable implementation of several agro-industrial processing chains in view of the green circular economy and the valorization of the biodiversity of the Alcotra territory. In particular, the management of waste deriving from agricultural and food processing is one of the main topics of the project. Bud-derivatives, which represent a relatively new category of plant food supplements obtained macerating meristematic tissues of trees and plants (i.e., buds and young sprouts), are very expensive products compared to other botanicals, since the collection period of their raw materials is extremely limited over time3. Lavender essential oil has been widely used as herbal medicine for centuries in the traditional medicine. The solid by-products remaining after the distillation of lavender, are considered as a potential and still under-utilized source of phenolic compounds to be valorized.
In this study, the innovative and eco-compatible Pulsed Ultrasound-Assisted Extraction (PUAE) demonstrated to be a promising strategy to valorize these waste and by-products by obtaining in a very short time (10-20 min), using only food-grade extraction solvents, new potential ingredients to use in different fields (food, cosmetic, pharmaceutical etc.).
