Suffolk Recycles advises to safely dispose of the test kit, place all of the items from the test and the plastic packaging into the bag provided and then put this bag with your general waste into your kerbside bin for disposal. This applies whether the test result is positive or negative. 

None of the plastic items or plastic packaging should be put into the recycling bin. They are not recyclable in your kerbside recycling bin.

If there are disposable gloves and disposable masks in the kit, these are also not recyclable and should be put in the general waste bin. 

The outer cardboard packaging and paper leaflets from the test kits can be recycled in your kerbside recycling bin.
