WRAP Case Study
The Waste and Resources Action Programme, known as WRAP, published a Case Study: USING COMPOST FOR URBAN TREE PLANTING in May 2004.
The case study is focussed on the beneficial use of compost in the manufactured products Heicom tree sand and tree soil for planting trees in urban areas. Heicom tree soil consists of over 50% compost, a higher content than used in tree sand. The aim is to create a consistent high quality growing medium for trees in unpaved urban areas with poor soil conditions.
Using compost as part of Heicom tree sand and Heicom tree soil production, rather than non-organic alternatives, offers an environmentally sustainable way to add nutrients to the sand with out causing any negative side effects. The use of compost in the tree sand and tree soil also helps suppress disease and increases the sand's water retention, all of which help to improve the survival chances of the urban tree.
