Up-Cycling of <i>Olea europaea</i> L. Ancient Cultivars Side Products: Study of a Combined Cosmetic–Food Supplement Treatment Based on Leaves and Olive Mill Wastewater Extracts
Published 2023-07-01“…In recent years, a reversal of the global economic framework has been taking place: from the linear model, there has been a gradual transition to a circular model where by-products from the agri-food industry are taken and transformed into value products (upcycling) rather than being disposed of. Olive tree pruning represents an important biomass currently used for combustion; however, the leaf part of the olive tree is rich in phenolic substances, including hydroxytyrosol. …”

Biochar Can Improve Absorption of Nitrogen in Chicken Manure by Black Soldier Fly
Published 2023-04-01“…(1) Background: There is growing interest in using insects to treat nutrient-rich organic wastes, such as the black soldier fly (BSF), one of the most efficient organic waste recyclers for upcycling nutrients into the food system. Although biochar (BC) was shown to enhance nutrient retention and the final product quality during the composting of livestock and poultry manure in many previous studies, little information is available on the effect of BC on livestock manure bioconversion by black soldier fly larvae (BSFL). (2) Methods: This study investigated the effect of adding a small amount of BC to chicken manure (CM) on the bioconversion system of the black soldier fly (including N<sub>2</sub>O and NH<sub>3</sub> emissions and the final distribution of nitrogen during the treatment process). (3) Results: The lowest N<sub>2</sub>O and NH<sub>3</sub> emission and highest residual nitrogen in the substrate were observed in the 15% BC treatment. …”
