Industrial process and products
Any biorefinery is a global technological system defined as a combination of physical, chemical and/or biological deconstruction, separation and functionalization technologies aimed at transforming biomass into intermediate or finished commercial products in a sustainable manner: food for humans and animals, chemicals, materials (including fibres) and energy.
The biorefinery must be apprehended according to a historical vision, built from the terms co-products, by-products and waste (article L541-4-2 of the Environment Code and the framework directive on waste EC 2009/28) . In the initial historical logic, a biomass for a product by a process, the by-products are by essence induced, that is to say inseparable from the production cycles of the major commercial product(s). After possible modifications, the by-products evolve into co-products for specific uses. Consequently, they share with the main product the need to meet characteristic specifications, and each is suitable for being marketed directly for a particular use. Thus beet pulp has evolved from a by-product of sucrose to a co-product of beet sugar. The economic recovery is based on the product – co-product(s) set and the minimization of waste by identifying the specific uses imagined.

Lee Bio Technology
LThe LEEBIO™ process is based on the chemical separation of lignocellulosic residues into cellulose, lignin, hemicelluloses and silica.
This process is non-degrading and only uses formic acid at atmospheric pressure. The consequences of this chemical separation are very low energy consumption and high separation efficiency.
The table below gives you some numerical values of various lignocellulosic biomasses (expressed in % relative to the dry matter). These values were determined by the Biomass and Green Technologies Laboratory of ULiege.
The acronym LEEBIO stands for Low Extraction Energy of Biomass.

Our economies are heavily dependent on petrochemicals, but the sector receives far less attention than it deserves.
Petrochemicals are one of the key blind spots in the global energy debate, especially given the influence they will exert on future energy trends.
The bioeconomy contributes to the development of economic value and jobs in Normandy.
