Global warming has become an increasingly important issue around the world today due to the rise of anthropogenic greenhouse gases emission, which gives several negative impacts on human life. There are some techniques have been studied and assessed i.e. physical mechanism by injected CO2 to the geological formations, chemical mechanism with artificial tree technology and biological mechanism by increasing the primary production through iron enrichment in high nutrient-low chlorophyll (HNLC) waters as well as mixing of water column below the sea surface. Those technologies, which are well known as Carbon Capture Storage ‘(CCS) technology, are expected to be applied to reduce the oncentration of anthropogenic CO2 in the atmosphere and to minimize the global warming. The Center of Environmental Technology, Agency for the Assessment and Application of Technology (BPPT) will carry out a research concerning CO2 reduction by a phytoplankton culture in a photobioreactor in three years. The main objective of this research is to assess the CO2 uptake capability of tropical phytoplankton. In this paper, we would showed the creteria and design to assembly a photobioreactor esspesially a air lift photobioreactor. To improve performance photobioreaktor, the materials included design criteria and the dynamics of fluids in fotobioreaktor have to considered propoerly. Other the hand, the selection of the most productive species and selection of appropriate media and economically also important to be done. Keywords: global warming, creteria and design, greenhouse gas, air lift photobioreactor

The use of bio-based material is now widespread in insulation concrete, for example hemp concrete. The bio-based materials in concrete provide many advantages: lightness, sound and thermal insulation, hydrothermal regulation while contributing to a reduction in the environmental impact due to the carbon capture during the plant growth. The development of materials incorporating plant is therefore an important objective for the construction. The next step will be to introduce bio-based materials in structural mortars and concretes. The project FIBRABETON proposes to substitute synthetic or metallic fibers by natural fibers in screed and slab. After a selection of biomass on the resources availability, separation and fractionation are the key step in processing to obtain technical natural fibers. Bulk fiber shaping and packaging methods for easy handling and transportation are tested. Then, functionalization of technical natural fibers by physical & chemical treatments to improve the durability with cement paste is carried out. The second step concerns the introduction of treated or not treated fibers in mortar and concrete formulations. The variation of the nature of the biomass, fibers shape and dosage in concrete are studied. The workability, the compressive strength and withdrawal resistance are measured in order to obtain the best formulation parameters. The evolution of properties over time is also evaluated. The project FIBRABETON is carried out with ESTP, FRD and Vicat and is subsidized by ADEME, Grand Est region and FEDER.

The close adaptation of camel to its desert environment could explain its weak expansion out of the arid lands of the world. This adaptation can contribute to the desertification combat, attesting to its small ecological footprint with traditional extensive farming. The camel population in the world, despite its active growth, remains marginal, and its contribution to the greenhouse gas emission is negligible. However, the current trends to the intensification of camel productions could change the impact of the species on the environment and on animal metabolism. The necessity to expect a better productivity face to the growing demand could lead to a “specialization” of the camel farms and a specific selection of the camel. Such trends require care with a possible erosion of the camel biodiversity and the consequences on the interactions between the emerging camel production system and the environment.

Purpose-designed, water-lean solvents have been developed to improve the energy efficiency of CO2 capture from power plants, including CO2-binding organic liquids (CO2BOLs) and ionic liquids (ILs). Many of these solvents are highly viscous or change phases, posing challenges for conventional process equipment. Such problems can be overcome by encapsulation. Micro-Encapsulated CO2 Sorbents (MECS) consist of a CO2-absorbing solvent or slurry encased in spherical, CO2-permeable polymer shells. The resulting capsules have diameters in the range of 100–600 μm, greatly increasing the surface area and CO2 absorption rate of the encapsulated solvent. Encapsulating these new solvents requires careful selection of shell materials and fabrication techniques. We find several common classes of polymers are not compatible with MECS production, but we develop two custom formulations, a silicone and an acrylate, that show promise for encapsulating water-lean solvents. We make the first demonstration of an encapsulated IL for CO2 capture. The rate of CO2 absorption is enhanced by a factor of 3.5 compared to a liquid film, a value that can be improved by further development of shell materials and fabrication techniques.
