55% Growth in Anaerobic Digestion Capacity in the UK in 2013/14 Announced

The official Anaerobic Digestion UK figures are out, and confirms that there was an amazing 55% Growth in Anaerobic Digestion Capacity in the UK over the 12 months 2013/14. This massive over 50% growth, is described simply as being "significant growth", by WRAP (the compiler of these figures - See the EAEM Press Release, which is copied in full below).

In any other sector this rate of growth would be considered to be huge, and the national press would be full of the achievement. So, why is this latest ASORI report announcement being treated in such a luke-warm manner?

We suggest that the reason for this is that the officials are embarrassed to have missed their own target by a large margin, as follows (see the extract from below). The achievement of 117 operational biogas sites in the UK at the end of 2014, showed even then, that they were not going to get anywhere near the government's 2011 target of 1,000 operational AD Plants for 2015, and they could not therefore declare it for the success that it undoubtedly has been.

To help convey how far the projections fall short of the target, we have included below part of an article by Energy and Environmental Management (EAEM) Magazine. This explains that the current operational AD Plant number has been growing a lot more rapidly since that time, with the pace of plant commissioning accelerating. Currently, there are 400 Anaerobic Digestion plants now in use according to EAEM Magazine. 

At this rate the magic figure of 1,000 AD Plants in operation in the UK, will finally only be reached some time in 2017.

AD Sees Significant Growth Says Latest Sector Survey

Anaerobic digestion (AD) has grown significantly in the UK, according to the latest sector survey (ASORI), published today by WRAP.
WRAP’s comprehensive study of the AD sector (which complements the Scottish survey of the organics reprocessing industry – also published today, by Zero Waste Scotland*), for the calendar year 2013, shows that:
  • the number of operational sites increased by 34% (up from 87 to 117);
  • operating capacity is up by 55% (from 2.07mt to 3.20mt);
  • 51% more organic material is being processed (from 1.69mt to 2.55mt); and,
  • employment in the sector has increased by 36% (with 482 full-time equivalent jobs compared to 354 in 2012).
In addition, there has been an increase in all the types of feedstocks processed - separated solid food, liquids, manures and crops. However, food and drink waste continues to be the largest proportion of the material processed - with separated solid food accounting for 38% of the feedstocks reported in the survey and liquids 30%.
Food manufacturers and processors provide the biggest proportion of the feedstock, however the volume of material sourced from local authority collections, has increased by more than a third**.
Over a million tonnes of digestate (the product of AD) was applied to agricultural land in 2013 – that’s 98% of total digestate use – demonstrating the benefits of readily available nutrients as well as potentially reducing the reliance on inorganic fertilisers.
Ian Wardle, Head of Organics and Energy at WRAP, said: “It’s fantastic to see such positive results from this survey. The industry is turning a wide variety of wastes into valuable renewable energy and digestate that can be used by farmers as a fertiliser.
“Each year we are seeing the sector grow and this year’s data shows the AD industry is starting to make a marked contribution to the UK economy. Industry has always supported this survey and this year’s excellent response is testament to that.”
The report was commissioned by WRAP, working in partnership with the Renewable Energy Association’s Organics Recycling Group (REAORG), Anaerobic Digestion and Bioresources Association (ADBA), and the Environmental Services Association (ESA). It is widely recognised as the most definitive picture of the organics recycling industry.

Notes to editors
*The Scottish report - A Survey of the Organics Reprocessing Industry in Scotland 2013 - was managed and delivered by WRAP on behalf of the Scottish Government having been initiated in 2013/14. The survey of Scottish AD sites was part of the UK ASORI project, however the Scottish Government also funded a survey of the composting sector.
**Of the feedstock for which sources were stated, it increased by around 35% from 170,000t to 230,000t.

Recent UK Anaerobic Digestion Developments and Future Projections
"The growth of anaerobic digestion in the UK has not met Defra’s strategy target of 2011, when 1,000 new digesters were to be built by 2015. In fact less than half that figure was achieved, nevertheless the industry has been growing rapidly in real terms in the UK. Considering, the difficult economic circumstances, and reticence […] The post Recent UK Anaerobic Digestion Developments and Future Projections appeared first on Rinobs Renewables. "

Anaerobic digestion steps on the gas - Energy and Environmental Management (EAEM) Magazine

"Energy and Environmental Management (EAEM) Magazine. Commissioning of the UK's 400th anaerobic digestion (AD) plant by food waste management company Biogen in South Wales marks a milestone for the industry, in a year which has seen 102 new plants open. The announcement was made at the UK AD ...AD feedstock guidelines get industry backingMaterials Recycling World500% jump in volume of recycled UK food wasteEat Out Magazineall 3 news articles »"


A massive 50% rise in Anaerobic digestion plant numbers (and UK capacity in use) to 117, was recorded in 2013 (the latest year for which data is available).

But, the achievement has been played down by the UK government. We think that the reason for that is, that a target of 1,000 biogas plants was set for 2015, but even now (mid-2015), only 400 have been commissioned, with the knock-on effect that by the end of 2015 there will still be less than half of those 1,000 plants, operating in the country.

The UK/ European biogas industry has been, and still is, growing rapidly and the momentum is growing. We would like to point out that this growth is being achieved, by project promoters, despite uncertainties caused by changes which have been made to the subsidies on offer by the UK government.
