Securing markets and maximising value from biosolids and other biofertilisers

21st – 22nd May 2019, Leeds

Day 1 – 21st May

Sustainable landbank: Building and maintaining confidence in biosolids, biowastes and other bioresources

Although materials such as biosolids and food-based digestates have different origins, the challenges with land bank access and security can be very similar. For example – fragments of plastic are known to be present in biosolids, food-based digestates and green-waste composts. To date, there is little or no evidence that this creates issues in soils where these materials are applied – but perception that there might be an issue is likely to be high.


Sometimes it doesn’t matter how strong the evidence is to support a particular practice – if the perception is sufficiently negative, that practice may never gain widespread support. Day 1 of this event will provide an opportunity for different sectors to share experiences and best practice – and explore how perceptions and evidence might better interact to secure long term resilience in land-based markets.

Key themes

  • Changing perceptions – how social and applied sciences interact
  • Successes in consumer engagement
  • The role of quality assurance schemes
  • Opportunities for cross-sector collaboration

Day 2 – 22nd May

Marketing Biosolids, biowastes and other bioresources:  minimise costs and maximise returns

Biosolids and other bioresources (such as composted garden wastes and digestate from food waste AD) offer a number of benefits to farmers and growers. They help to reduce reliance on conventional fertilisers – by supplying nitrogen, phosphorus, potash and a range of trace elements – and in some cases help to improve soil physico-chemical properties by supplying organic matter.

However, the business of land application is often a cost centre. The demonstrable fertiliser value of materials does not always cover the costs associated with hauling, storing and applying them to land – and in many cases no attempt is made to recover even part of the cost from the end user. A partial budget for a food waste AD site shows the scale of these costs in comparison with income streams, and the importance of minimising these costs where gate fees are no longer paid:

Day 2 of this conference focusses on strategies to reduce costs / improve value from land-based markets for biosolids and other bioresources.

Key themes

  • Marketing strategies for compost and digestate
  • Are PAS100 and PAS110 worth it?
  • Marketing strategies for biosolids
  • Can BAS make a difference?
  • In-house vs out-sourced service provision
