Abstract
This study investigates cow behaviour when visiting two GreenFeed Emission Monitoring (GEM) units within a Part-Time Grazing (PTG) system. Two separate PTG systems were assessed in Sweden and Norway, involving Nordic Red and Norwegian Red dairy cows, respectively. In Sweden, 24 cows were allocated to treatments with restricted access to pasture, either daytime or nighttime grazing. Meanwhile, the Norwegian PTG involved 33 cows with free pasture access, categorized by varying training levels (Partially or Fully). In both PTG systems, cows were exposed to GEM units positioned indoors (Indoor) and in the grazing pastures (Pasture), with individual visitations recorded. Significant variations in visitation patterns were observed. In the restricted access PTG, Nighttime grazing access cows exhibited reduced visits to the Indoor GEM unit but increased visits to the Pasture GEM unit compared to Daytime grazing. Conversely, within the free access PTG, fully trained cows demonstrated elevated visits to the pasture GEM unit and total visits compared to their partially trained counterparts. These findings highlight the influence of temporal conditions and training levels on cow-visiting behaviour within PTG systems.

Shrimp and crab shells are the most promising and viable source of raw material for the manufacturing of chitin and its derivatives. In-depth understanding of the biological properties of chitin and scientific advancements in the field of nanotechnology have enabled the development of high-performance chitin nanomaterials. Nanoscale chitin is of great economic value as a functional and reinforcement material for a wide range of applications including water purification. The use of nano-chitin to produce (bio) nanocomposites offers a good opportunity to prepare membrane materials with enhanced functional and structural properties. Chitosan-based membranes are found to be effective in water purification for the removal of pollutants like organic wastes, heavy metals, antibiotics, pathogenic microbes and acid waste. These membranes are environmentally friendly and can be used as a method to reduce humic acid waste from the aquatic environment. This review focuses on the preparation, characterization and chemical modification of nano chitin membrane and its application for water purification and water treatment.

Horticultural food waste can be recovered to produce high-value products. Appropriate green solvents and a selection of cleaner production could unlock waste into useful resources for human health. This will significantly reduce greenhouse gas emissions, and CO2 production, and create economic opportunities to contribute to food security.
