ANR Project Sustain’Apple (2014-2018)

In France, apples are the most consumed and exported fruits. The sustainability of the whole supply chain is increasingly called into question from a sanitary and phytosanitary (SPS) point of view. Sustain’Apple aims to shed light on the organizational and institutional solutions that may be implemented at all stages of the supply chains (short and long chains). The project, which can be classified in the 2nd axis as defined by the ANR, will run for a 4-year period with the requested grant totaling €876,305. The consortium brings together all the competencies necessary to address these sustainable apple chain issues with on the research side, INRA, CIRAD, IRSTEA, Montpellier SupAgro, ESA Angers and UAPV are concerned through the involvement of UMR MOISA, UMR Innovation, UMR ITAP, PSH and UERI Gotheron.

The project includes a LCA work package that aims to compare the environmental performances of different chains, from orchards to final consumers.

BioFimE: Control of biofilms in paper mill process by combined actions of low environmental impact

Production of pulp, paper and cardboard is one of the most water-consuming industrial process. Since twenty years, the law encourages industrial sites to reduce their water consumption and their discharge to the nature.

The paper industry tries to reduce the water consumption in its processes: between 1970 and 2004, the amount of fresh water consumed per ton of paper has been reduced of 90% (source CEPI[1]). Nevertheless, the closed loop and the water recycling in paper industry lead to the creation of biological sedimentation named biofilm (or slime) in water pipes and paper machine .

Those biofilms lead to major issues as stop of paper production … The chemical agents used as treatment present some health and environmental dangers.  Some laws may forbid the use of some agents of this type. Therefore, paper mills and producers of those chemical agents are in search of alternatives.

The BioFimE project aims at reducing chemical agents consumption in paper industry by trying to fight against biofilms with mechanical, chemical and biological actions. Those complementary actions should be respectful towards the environment and adapted to the production context.

The Life Cycle Assessment (LCA) aims at assessing the different options to fight against biofilms and identify the hotspots.
