Tenant Update: Offensive waste (Tiger Bag) update – January 2024

As part of CHP’s commitment to provide sustainable, fit for purpose estate and facilities we commenced the implementation of the offensive ‘tiger’ waste stream in 2022.  More than 66% of buildings where CHP is responsible for cleaning and waste services have instigated an offensive waste stream since 2022, with the remainder due to complete this process by the end of the year.

Clinical waste is different to offensive waste.

Offensive waste (OW) has no hazardous properties and can be treated or disposed of in a similar way to domestic waste, and with a far less energy-intensive process compared to clinical (orange/yellow bag) waste. This results in lower carbon emissions and reduces the environmental impact. Correctly classifying and segregating offensive waste is vital to achieving targets as set out in the NHS clinical waste strategy.

Implementing Offensive Waste segregation

  • Follow the instructions for waste disposal outlined on posters and bin labels.
  • Correct segregation is crucial.
  • Use the yellow and black striped bags for non-infectious bandages, masks, and dressings.
  • The tiger waste stream is financially beneficial too… it is 30p per bag cheaper than clinical waste
  • Ensuring waste is segregated and disposed of into the correct waste stream is key to realising these environmental and financial savings.
  • Waste stream contamination can lead to Health and Safety risks and costly non-compliance penalties.

‘At CHP 66% of our buildings have already implemented these changes, with more implementing them in the coming weeks. We have set a target of 80% to be complete by the end of March 2024 and the remaining buildings by the end of the year. Our Operations Teams are working hard to implement this project and you may see some changes across waste management in your buildings in the coming weeks as we try to push this new guidance forward.
