SRC management on landfill

The management of non-hazardous waste storage facilities (ISDND) involves the management of leachates resulting from the degradation of buried waste. The operator is obliged to collect and treat these leachates, whether or not discharge into the natural environment is authorized, while complying with the regulatory limit values set out in the ministerial order of 2016 (at a minimum, the criteria in appendix 3 of the amended ministerial order of September 9, 1997, reproduced in appendix 1 of the order of February 15, 2016) and in the prefectoral order authorizing site operation. When discharge into the natural environment is not authorized (prohibition of discharge into watercourses in certain regions of France) or impossible (absence of watercourses nearby), plantations of TTCR (very short rotation coppice) can be a solution for evacuating treated leachates in situ instead of treating raw leachates ex situ.

The environmental objectives of a project to irrigate TTCR with treated ISDND leachate are to :

– Reduce or eliminate the flow of treated leachate outside the site perimeter;

– develop energy crops such as TTCR used for biomass production on marginal soil;

– develop the ISDND site, a marginal soil of low fertility ;

– improve the site's integration into the landscape.

This article summarizes all the information from the four-year R&I project (conducted by Veolia Research and Innovation – VERI, in collaboration with the FCBA (Forêt Cellulose Bois Construction Ameublement) technological institute) useful for the establishment and operation of TTCR on ISDND sites. It explains how to set up and manage a TTCR plantation on a marginal ISDND site. It also gives recommendations on the technical itinerary for TTCR (from soil preparation to harvesting).
