  Gas bioconversion An opportunity for the ecological transition

  In the face of the climate emergency, the valorization of industrial and biological gases (e.g., H2, CO2, CH4) represents a strategic lever for a low-carbon circular economy. This article analyzes the potential of their bioconversion by microorganisms to produce biofuels, chemical compounds, and proteins. It presents the microbiological foundations, available processes, critical operating conditions, technological bottlenecks, and prospects for industrial integration.

  Energy Recovery from Nuclear Waste Generated by the French Nuclear Industry

  The French nuclear industry relies on uranium-235 fission, which represents only 0.7% of natural uranium, requiring enrichment. This process generates large amounts of depleted uranium, considered waste in thermal reactors, along with spent fuel. However, these materials still contain valuable elements such as uranium and plutonium. Fast neutron reactors can convert uranium-238 into plutonium-239, greatly increasing energy extraction. This article outlines these materials and their potential uses, including MOX fuel and specific applications such as long-lasting nuclear batteries.

  Energetic Transition. Challenges and Outlooks

  The primary energy supply is still mainly provided by fossil fuels. In addition to the risks of depleting these resources which are only available in finite quantities, the world is facing the major challenge of global warming, due to greenhouse gas emissions, the main one being carbon dioxide emitted by combustion. It is therefore necessary to ensure an energy transition to low-carbon energies as soon as possible, which requires a complete transformation of the energy system. The article presents the main technologies to be deployed.

  Biobased Epoxy Resins

  The development of biobased epoxy resins and the replacement of the diglycidyl ether of Bisphenol A, the most widely used epoxy monomer, are challenges for the industry to comply with regulatory requirements and societal expectations. However, this substitution is accompanied by changes in the reactivity of the formulation and the final properties of the materials. This article proposes to detail the stakes of this substitution, as well as a detailed review of the research work carried out by academic laboratories, as well as of the commercial products in development to propose ways of access to less harmful and more respectful epoxy materials. of the environment.

  Plasticization of a corn protein for Additive Manufacturing

  The Additive Manufacturing by molten Material Extrusion (AM-ME) of natural biopolymers opens up major prospects in pharmaceutical or biomedical field, for the custom production of edible and resorbable parts. This paper shows the interest and challenges to be met for the use of plant-based biopolymers using this 3D printing process. Based on the study of zein, a storage protein by-product of corn starch production, this paper details its suitability for AM-ME specifications by investigating its thermomechanical and rheological properties, as well as determining its adhesion abilities in the molten state.

  Biobased and/or biodegradable polyesters: from elaboration to end-of-life

  The article presents the different key-steps in the life cycle of biobased and/or biodegradable polyesters. It describes the elaboration processes of each of these polyesters, going back to the raw materials used, especially when these are of plant-based. These production processes can be biotechnological approaches as well as fairly conventional chemical methodologies. For each of these polyesters, the main functional properties and current or future applications are detailed and criticized with regard to the issues of today. Their strengths but also the drawbacks limiting their development are explained.

  Bio-based building materials and temporary carbon storage

  Nowadays, in the research of long-term solutions to limit the earth global warming due to green-house gas (GHG), the construction and building sector can play an important role. The setting of bio-based materials in new buildings or for renovation seems a reliable way of sustainability and tempo-rary carbon storage.This paper aims at analyzing the physical phenomena and issues, by taking into account the moment and duration of the GHG storage and emissions: which type of bio-based material: agro-ressource or wood ; which lifespan for the buildings and the materials ; amount of carbon uptake in each plant, dissolution kinetics of GHG; which end of life scenario.

  Bio-based plastics and recycled plastics in packaging

  Bio-based plastics and recycled plastics are more and more often used in packaging in France and elsewhere. These materials are complementary to the virgin plastics of fossil origin. They bring new functionalities and added-value to plastic and flexible packaging. Studies all predict a growth of these plastics in the years to come, but the growth rate is still uncertain.This article describes the current situation, the determining factors of this growth and the principal initiatives taken in response to the challenge of developing bio-based and recycled plastics in packaging.

  Bio-based techniques for water analysis

  There is currently an increasing need for fast and cost-effective analytical methods suitable for water pollutants monitoring and toxicological impact assessment. In this context, some techniques based on the specific properties of whole cells, enzymes, antibodies, DNA, biopolymers or materials of natural origin, appear as excellent alternatives or complementary techniques to classical chemical methods. This article will be more particularly focused on biosensors and biosorbents (principles, advantages and limitations, application to water quality assessment, new trends).

  Biomass gasification in supercritical water

  Biomass valorisation is at the heart of the energetic resources’ issues in the twenty-first century. Mainly regarding wet biomass, supercritical water gasification is an interesting process to produce a valuable energetic gas, due to its non-fossil origin. The operating conditions of supercritical water processes, the influence of the main conditions on the nature and conversion yield of this process are detailed in this paper. The most important laboratory pilots are presented, together with the first industrial developments.
