WP2: State-of-the-art: bioactives & substituting materials (incl. pre-tests)

State-of-the-art of wood-based bioactives

  • Review of recent relevant literature (bioactives in different tree species and tree parts)
  • Focus on activity towards selected key microbes in hospitals

Preliminary lab tests for antimicrobial properties of the selected bioactives

  • Evaluation and selection of the methods to be applied; selection of the microbes
  • Calibration of the methods
  • Determination of the required antimicrobial properties

Potential of selected wood-based materials in hospitals

  • Survey of the current and potential applications of wood-based coatings, textiles and surface materials in hospitals (companies involved)
  • Roadmap for further studies on the most promising solutions
  • Evaluation of existing research infra for the manufacture of demonstration materials and products; required modifications for the facilities 

WP3: Visualizing purity and hygiene level in hospital environment  by new camera technology
(Main coordinator Jamk, Sub coordinator VTT and KSSHP, connected WP 2, WP4, WP6)

Objective:

  • To find the most suitable optical technology to identify the purity and hygiene level of the different surfaces in the hospital environment
  • Improved material and cost efficiency

Backround:

  • Determination of the purity level  (3 levels)
  • Cost-effective methods (cleaning, curtain exchange, resource planning)
  • The spread of infectious diseases and the progress of bacterial strains

WP3 Actions phase 1:

  • Clarifying existing microbial and organic material detection methods and available optical technologies and combinations of those
    • Hyperspectral cameras for different wave lengths
    • UV- and IR-lights
  • Few potential methods will be selected for Action 2 

WP3 Actions phase 2:

  • Testing and verification of selected systems in the Living Lab environment
    • > applicability, functionality, techno-economic advantage

WP4: Research and testing of wood based antibacterial materials concerning applicability, availability and effectiveness in hospital environment, demonstrations in living lab environment
(Main coordinator Jamk, Sub coordinator VTT and KSSHP, connected WP2, WP3, WP5)

Objective:

  • To produce the most potential organic antimicrobial combounds (WP2) for testing in the laboratory and living lab scale . To test production methods for antimicrobial materials originated of virgin wood or wood processing industry.

Backround:

  • There are numbers of studies which have indicated that wood based organic combounds may work better against microbes and bacteria than fossil based substances. The studies also indicate that these can be produced from the wood by different methods – Scale!

WP4 Actions phase 1:

  • Recognition of the most potential substances and their sources based on WP 2. Studying availability and applicability, testing separation methods including demonstrations – scale.
  • Techno-economic evaluation of separation methods
  • Utilization of new camera technology (WP3)

WP4 Actions phase 2: 

  • Processing, production and further developing of selected substances including tests in living lab-environment
    • > applicability, functionality, techno-economic advantage

WP5: Addition of wood based antimicrobial substances to hospital environment materials, cleaning agents and coatings and replacing fossile based plastics / Piloryong, demonstration and testing 

  • Addition of antimicrobial substances: Hospital applications like textiles (cubicle curtains), cleaning agents, equipments, surface materials, coatings, etc
  • Replacing oil-based plastics by bio-based materials: E.g. Packages in hospital environment, disposable products, textiles, bed clothing, eating shield clothing, etc
  • Easy-to-clean hygienic coatings on various surfaces
  • Demonstration of selected cases in KSSHP Living-Lab environment
  • Testing: Antimicrobial viability and optical technology
     
  • Wood based antimicrobial substances and their addition to materials and coatings (Repolar, UPM, Walki, VTT, JAMK)
  • Bio-based materials to substitute fossile based plastic materials (Walki, UPM, PAPTIC, Welmu, Serres, VTT)
  • Addition of antimikrobial substances to cleaning agents (Kiilto Clean, VTT, JAMK)
  • Dirt repellant and easy-to-clean coatings (Millidyne, VTT)
  • Testing of antimicrobial activity (VTT, JAMK)
  • Living Lab –demonstration (KSSHP, Companies, VTT, JAMK)
  • Utilisation of camera based application to measure hygienity (JAMK)

WP6: Regulations regarding substances and materials used in hospital environment
(Jukka Lahtonen, KSSHP)

Expert group specialised on hospital hygiene and infection prevention

  • Hospital is a challenging environment to include new innovations:
    > procurement processes and patient safety
    > innovations are required to have scientific evidence regarding infection prevention
  • The infection prevention work is guided by infectious disease law, as well as international and national instructions
  • Three cleanliness levels in hospitals
  • Both cleaning services and hygiene experts are involved in the work package
