Two Excel calculators to help BPEX levy payers work out their statutory calculations required by the NVZ regulations are now available on the BPEX website: http://www.bpex.org.uk/PracticalAdvice/EnvironmentHub/NVZs.aspx. There is one for continuous throughput systems and one for batch systems, the batch one having a significantly different approach to working out throughput. If you have any queries regarding either of the calculators contact Charles Baines of BPEX charles.baines@bpex.org.uk.
