ISWA's Soils Project

ISWA's Soils Project aims at ‘quantifying the benefit of organic matter in compost and digestate when applied to soils’ and taking a lead in providing robust evidence base to link waste management and soil enhancement/improvement.

12 May 2020 -

Soils are an endangered ecosystem globally and there is currently great interest in reducing erosion and improving the organic matter content of soils.

This project aims to create four reports in order to summarize current knowledge about the fate of recycled carbon in soils, in particular, its sequestration and effects on soils by talking about key areas of the world where threats to soils are severe and could benefit from organic matter inputs.

These reports will also provide a tool for waste planners/managers and farmers, summarising how composting and anaerobic digestion can be used in different country situations, and how quality assured products can be usefully applied to soils. The reports can be found on the ISWA site under media publications.


Report 1: Municipal Organic Waste - A Global Perspective on Production and Recycling


On May 6th ISWA held a webinar representing the first of 4 reports of the ISWA-funded project investigating the benefits of compost and anaerobic digestate on soil.

The webinar provided a global perspective on the production and recycling of municipal organic waste. It was presented by the Chair and Vice-Chair of ISWA's Working Group on Biological Treatment of Waste (WGBTW) respectively Marco Ricci-Jürgensen and Jane Gilbert.
