Trommel at t’mill

Until a week ago, the term “trommel fines” was rarely heard outside a materials recycling facility (MRF) or a waste transfer station (WTS). But that was before Her Majesty’s Revenue and Customs (HMRC) issued the snappily titled Brief 15/12 – Landfill Tax: material used on a landfill site; and classification of waste.

For a routine clarification about how landfill tax applies to certain materials it has sparked a huge story, with outspoken opposition being reported in depth – but I’m surprised that there have been so few voices speaking out in favour of HMRC’s position, which seems to me to reinforce the pro-recycling intent of landfill tax.

Some industry professionals have claimed that the new interpretation of the laws will be a disaster for skip operators, who will have to pass on higher costs. Others have talked of a hike in the gate fees charged by MRFs and WTSs in order to cover the additional costs of disposing of material they are unable to separate. Skip lorries blockaded Parliament Square, while Richard Hunt of the Plant and Waste Recycling Show (PAWRS) somewhat improbably claimed he was “looking to get Max Clifford” on board, and that an injunction against the tax would be sought. Their protests led to a hurried further clarification from HMRC on 1st June, which some hailed as a victory although it seemed to change very little. So what’s really going on?


Brief history

HMRC’s statement of its position follows from a case it lost against Waste Recycling Group (WRG) in 2008. The court ruled that inert material used for “temporary structures” (daily landfill cover and other onsite engineering) was not “disposed of” and therefore wasn’t liable for tax. HMRC was ordered to repay tax to WRG; and £300 million of further repayments across the industry followed.

The Government responded with new legislation in 2009 to clarify what would count as a “use” of waste, and then in 2011 with a revised classification of types of inert waste. The interpretation of these pieces of legislation is the subject of the recent HMRC Briefs, which covered two key points.

  • Following the WRG ruling, some operators had sought to claim back tax paid on ‘top fluff layer’ material used to provide a protective layer between the landfill’s cap and the main body of waste. But, after discussions with operators and the Environment Agency, the HMRC concluded that this material “should be (and always should have been) liable to Landfill Tax as the waste material is disposed with the intention of discarding it” and disposing of it as top fluff doesn’t constitute a “use”.
  • Some WTSs and MRFs had classified fine residues, known as trommel fines, grit and screenings, as inert material. HMRC’s first brief stated that “Any residue from treated transfer station waste that is consigned to landfill will be very variable and it will be impossible to determine the origin and exact nature of the source material… [T]hese are not qualifying materials as listed in the Schedule to the 2011 Order.” In Brief 18/12, however, it made it clear that if fines were “made up from materials all of which qualify for the lower rate and in these circumstances the fine would qualify for the lower rate providing the necessary evidence could be demonstrated.” The strong presumption seems to be, though, that this evidence will not be easy to provide.


I can see the argument either way on top fluff – this layer is needed, but it is composed of material that has been accepted for disposal. But the case on fines seems unarguable. All of the evidence is that the fines typically have substantial organic content, and there’s no reason for them to be routinely classified as inert.


Overcoming inertia

So, what is the impact of these clarifications, and are they to be welcomed or lamented? I think there are two key points.

Firstly, it is worth thinking about who will be affected. Clearly, anyone who produces large amounts of fines and has been avoiding landfill tax by “using” fines as top fluff, or who has benefited from classifying fines as inert and therefore subject to £2.50/tonne landfill tax, will notice if the tax is hiked to £64/tonne instead.

MRFs and WTSs that are producing large amounts of fines but are locked into fixed price contracts with clients will be squeezed, and may well look to pass on costs where they can. It is understandable that the skip operators are unhappy – they’ll be at the sharp end, passing on increased costs to customers. Inert landfill operators may see a reduction in the volume of material they receive; non-hazardous sites will not be affected by tax (they simply collect it and pass it on to the HMRC), and will only suffer a reduction in income if they have been charging a higher gate fee for inert material.

It will be the sorting facilities that produce the largest amounts of fines that experience the greatest impact. Some facilities are more efficient than others – they separate more material and leave fewer fines. There is concern in some parts of the industry that there are firms that are simply shredding anything that can’t easily be sorted, and if that material has been passed off as inert fines, it undermines the case for investment in sorting technology.

Secondly, what will the reaction be? A lot depends on how wide the window opened by Brief 18/12 proves to be. By accepting that some fines may be inert, HMRC is placing a heavy emphasis on the enforcement of waste transfer notes by the Environment Agency, as there will be a significant financial incentive for WTSs and MRFs to continue to describe material as inert wherever possible. With strong enforcement, the market will shift in favour of investment in better sorting technology; without it, we can expect something more like business as usual.

My fear is that the Agency lacks the resources and the will to enforce effectively. If that proves to be the case, we will be reliant on the accuracy of waste transfer notes and the inspections carried out at landfill sites. Environmentally minded people should be hoping that HMRC shows its teeth and prevents recycling from being undercut through the perpetuation of the current approach to fines.

Hi Mike It is also interesting to read in the trade press that the HMRC claims it made the announcement at the behest of certain landfill operators. You’ve got to look at the structure of the industry to understand the winners and losers from this policy. Small skip companies with manually based sorting operations are likely to go to the wall with further consolidation of the sector as you need a pretty large site to process all skip inputs to the level of minimising non inert fines residues requiring landfill disposal. I don’t see how inert landfill will be affected… Read more »

Mike, you may be interested to see this reaction from the construction industry press – seems that HMRC are talking in conciliatory terms to industry representatives, so perhaps the concerns about loopholes and the lack of will for enforcement that you raise are valid:

Mike you make a very good argument – and to be fair David Palmer Jones of Sita made similar arguments when the controversy broke. The secret, however, is in the timing. If HMRC had got this clarified a lot earlier – before the Tax had reached £64 a tonne- or if they had given 6 months notice of the new guidance, they might have avoided most of the row. In politics no-one likes a cliff edge and I guess you can be pretty persuasive if you have a fleet of skip lorries and a jubilee to threaten. But the principle… Read more »
