24 October - FARE contributes to an opinion paper on the N2O emissions

The return of crop residues to the soil after harvesting, such as cereal straw or the destruction of plant cover crops, maintains the soil's stock of organic matter and recycles nitrogen for subsequent crops. However, nitrous oxide (N2O) emissions are associated with the decomposition of residues, during the nitrification and denitrification processes by soil micro-organisms.

Pretreatment of biomass is necessary to improve its enzymatic accessibility and its recovery as a source of carbon. Among the existing pretreatments, dilute acid pretreatment has great potential, but it still needs to be optimised to improve its chemical and economic performance. To this end, the comprehensive dataset presented here and the models derived from it provide an overview of the chemical evolution of wood as a function of pre-treatment conditions.

Field retting is the first stage in the transformation of fiber crops in Europe, facilitating the subsequent mechanical extraction of cellulosic fibers of industrial interest. However, monitoring retting still depends on empirical knowledge.

Come in our lab

Welcome to FARE lab!


Uncovering the mechanisms and tools shaped by Nature to improve the use of renewable carbon and to contribute to sustainable development: this is the ambition of FARE laboratory (Fractionation of AgroResources and Environment).

Our mission, inside the network of our INRAE and URCA partner labs, is focused on three key points of the biological / technological transformation of lignocellulosic plant biomass, for non-food usages:

- follow the degradation of lignocellulose (culture residues, litters) by soil micro-organisms in the field, in order to maintain fertility and to favor ecosystem services necessary for a sustainable agriculture (input management, carbon and nitrogen cycles);

- fractionation of lignocellulose by enzymatic or microbial biotechnological processes, to produce chemicals of interest for chemistry and energy, while respecting the green chemistry concepts (2G bioethanol, sugar-based surfactant,…);

- using agro-sourced fibres and polymers, to design innovative nanostructured materials with new optical properties (protective films and coatings), or composite materials with high technical and environmental performances (light, recyclable, biodegradable,…).
