ABSTRACT

This research project focuses on the problem of organic (or food waste) waste recycling in Flanders, Belgium. Here, the total amount of organic waste produced annually by restaurants is estimated at 166,000 tonnes. Despite being in the evolution towards a circular economy, more than 61% of the restaurants do not collect organic waste separately from residual waste. Within the research, this problem was explored from a human-centred perspective by analysing existing food-waste collection and processing equipment, and by observing the kitchen workflow and interior design of different urban located restaurants. The aim of the research was to identify design opportunities to integrate and optimize the collecting and recycling of food waste in restaurants. In sum, it was possible to distinguish different elements, variables and constraints across the various restaurants related to the disposal and handling of food waste in the kitchen and in the clearing area during the shift. The paper concludes with design requirements for the optimization of food-waste recycling systems, which are related to the cost of the system, the effort that is needed, the lack of space, potential bad odour, hygiene matters, integration in the workflow, organization of the workspace and use of additional resources and energy.

ABSTRACT

The objectives of this study were to assess the acceptability and usability of a newly developed intradermal prototype device, VAX-ID™, in healthy subjects. In April 2012 an investigational study was conducted in healthy subjects aged 18 to 65 y. To compare injection site and route of administration, subjects were allocated to 4 subgroups, either receiving subsequently 2 intradermal (ID) injections (one in the forearm and one in the deltoid) or an ID (forearm) and an intramuscular (IM) (deltoid) injection. All injections contained saline solution. Acceptability was assessed with a subjects' questionnaire and a daily electronic diary for 5 d. Usability was assessed with a vaccinators' questionnaire and an expert panel. A 10-point Visual Analog Scale was used to score several statements on usability and acceptability. A total of 102 healthy subjects were enrolled in the study (age: 19-63). No statistically significant differences were seen in demographic characteristics between the ID and IM groups. Anxiety before injection, pain during injection and duration of injection were rated significantly lower for ID compared to IM. One day after the injections, redness was reported more often after ID injection in the forearm versus ID in the deltoid; pain at injection site was reported significantly more often after IM vs. ID injection. The new VAX-ID prototype device was found easy to handle, easy to use and safe. The new VAX-ID prototype device was shown to have a high degree of acceptability as well as usability. Further studies with VAX-ID will be conducted using vaccine antigen allowing assessment of immunogenicity and safety. Additionally, these studies will help to further improve VAX-ID in terms of accuracy of delivered dose and feedback to the vaccinator. (NCT01963338).
