Environmental valuation of in-port shipping emissions per shipping sector on four Spanish ports.

This work provides an insight into the external costs associated with ships which had been berthed in four Spanish ports before COVID-19 was on the agenda. Firstly, on a port-by-port level and by individual vessel types, as this can also provide valuable insights. The economic valuation is based on the combination of the significant bottom-up European studies which follow the impact pathway approach (IPA) to calculating costs from transport air emissions.

Potential of cold-ironing for the reduction of externalities from in-port shipping emissions: The state-owned Spanish port system case.

This paper provides insights into the potential of cold-ironing for the reduction of externalities. External cost derived from the emissions of CO, NO, SO, and PM from berthed ships in the Spanish port system during 2016 are estimated providing a Spain-wide empirical evidence into where the highest externalities exist and where, on a port by port level, the introduction of cold ironing could yield the highest potential on reducing said externalities. The combined overall external costs from both local and global effects of shipping emissions from berthed vessels were between 326 and 440 million Euro.

Evolution of carbohydrates of pre-cut mango slices subjected to osmotic dehydration.

Haden mango slices (non-osmotic dehydrated, NOD) were immersed in calcium chloride (2 g/l), citric acid (5 g/l), hydrogen peroxide (25 ml/l) and sodium benzoate (20 g/l) solutions. Slices to be treated with osmotic dehydration (OD) were first immersed in calcium, then placed in the osmotic solution (sucrose 65 degrees Bx, 30 degrees C) and 211 mbar vacuum was applied for 30 min. After the osmotic treatment, the slices were immersed in the same solutions as for NOD slices.
