Landscape and Regeneration: Compost Case Studies

13th December 2016

WRAP’s collection of landscape and regeneration compost case studies investigate cases where high quality compost has been a key component in infrastructure and landscaping projects.

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

Rapid riverbank vegetation curbs flooding

Compost socks installed along the banks of the award winning Centenary Riverside nature reserve situated along the River Donn. They were able to withstand the scouring action of the river as well as provide a secure area for vegetation to establish.

Compost socks put the brakes on soil erosion on engineered roadside slopes

A trial carried out along the embankment of the new A421 extension in Bedfordshire showed that where compost socks had been installed run-off had reduced by 100% in 3 out of 4 rainfall events.

PAS 100 compost swings into action with sustainable golf course footpaths

Marsden Park Golf course in Nelson (Lancashire) demonstrates how PAS 100 compost, used within a geogrid system, can provide a green alternative to hard landscaped footpaths as well as protecting soil surfaces against erosion.

PAS 100 compost and recycled aggregates form building blocks for canal regeneration

At Woolston New Cut Canal near Warrington, former industrial works included a tannery. When PhD students were tasked with exploring the possibilities for phyto-remediation – using willows to take up contaminants in the silt and sediment – their recommendations called for the re-wetting of the canal to retain contaminants in situ and protect the canal basin.

The resulting canal restoration, part funded by WRAP (Waste & Resources Action Programme), employed a range of applications involving PAS 100 compost and recycled aggregate blends to support canal-side vegetation and found early establishment of grasses and wildflowers prolific.

Compost holds back erosion

Trial demonstrates how compost can protect a development against erosion during construction. At Redding Park near Falkirk, compost blankets were applied across a slope, protecting it from erosion casued by rainfall; whilst compost socks reduced the amount of soil lost from the site.
