Digestate & Compost use in Agriculture - Risk assessment overviews

Zero Waste Scotland have produced brief overview documents of the findings from the larger risk assessment procured in partnership with WRAP.  The documents examine the safety of digestates and composts when used on agricultural land.

Background information on the regulatory controls governing compost and digestate production and use in Scotland is also provided.

A more detailed summary of the risk assessment work can be downloaded from the WRAP website.

Digestate and compost good practice guidance

We have developed guidance for farmers, growers, advisers and agricultural contractors on how to maximise the benefits of using digestate and compost as renewable fertilisers.  These documents highlight:

  • Integrating renewable and bagged fertilisers can increase crop yields and reduce fertiliser costs;
  • Renewable Fertiliser Matrix shows how digestate & compost can be used with different crops;
  • Tailored guidance available for farmers and agri-contractors;
  • The guides also include a helpful check list.

The project was funded jointly by Defra, WRAP, WRAP Cymru and Zero Waste Scotland.
