Using compost and digestate - creating sustainable landscapes

Whether transforming a large brownfield site or running a municipal tree planting scheme, using compost can provide developers, local authorities, planners and landscape professionals with some significant benefits.

What are the benefits?

For brownfield projects:

  • Removes costs associated with excavating and disposing of poor quality soil.
  • No need to purchase new topsoil - surplus, fit for purpose on-site materials, can be used as a component of a manufactured soil, reducing landfill and transportation cost.
  • Cost efficient - even allowing for purchase, haulage and spreading costs, compost’s short and long-term contributions to soil fertility make it very cost efficient.
  • Improved soil structure - compost improves the structure of the soil allowing machines to work it with less effort. The soil becomes more tolerant to traffic too.

WRAP has supported a number of trailblazer projects across the UK where quality compost has been applied to brownfield land - to find out more, visit WRAP brownfield projects.

For landscapers:

  • Spend less on fertiliser - costs can be reduced as compost contains most of the nutrients required by plants.
  • Weed suppression - by applying compost mulches to flower beds and around trees, herbicide and ongoing maintenance costs can be cut. Compost has no seed bank and can act as a natural herbicide.
  • Healthy plants - plants grown in compost are more likely to survive. Beneficial microorganisms in compost help suppress plant diseases, saving money on plant replacement labour.
