A new rule for waste operators to ensure they are paying the correct amount of landfill tax has been set.

Under ‘Loss On Ignition’ (LOI), waste operators will have to keep samples of their tested products to show they are paying the correct tax.

According to the UK Government Chemist, fines are classified as the smaller fractions of waste produced by mechanical treatment processes.

The samples must be tested in a laboratory to determine the LOI at 440 °C, it added.

Wastes with less than 10% of LOI qualify for a lower rate of landfill tax but there is a transitional period for wastes with an LOI up to 15 %, it stated.
