During the last decades the oleochemistry has gradually flooded our everyday life through a mass of products and applications. This is mainly due to the wide structural diversity and reactivity of fatty acids and the growing demand for bio-sourced goods. Today, almost one quarter of the global vegetable oil production is dedicated to nonfood applications, the contribution of animal fats being much more modest. Excepted biodiesels, the chemical applications of tropical edible oils depend on their fatty acids composition: lauric oils (coconut and palm kernel) and palm stearin will be mostly converted into surface actives ingredients while unsaturated oils rather will be subjected to double bond functionalization or cracking. Alongside of major vegetable oils only a few non-edible tropical oils are exclusively intended to oleochemistry such as Castor and Jatropha. Some other non-food oilseed crops (Cuphea, Lesquerella, Vernonia, black mustard. . .) are promising but further researches are still needed for their development in Southern Countries. In the future, the production increase of major vegetable oils and the development of new ones will face many challenges relating to environmental issues, competition between food and non-food uses and between non-food applications themselves.

Powdered activated carbon is used in oils and fats refining to bleach and purify vegetable oils and fish oils. Actually, this powder makes it possible to detoxify crude fish oils and to eliminate contaminants like PAH, dioxin and PCB. Nevertheless, the powdered activated carbon used is painful because it is pulverulent. Nowadays, producers advise filtration plates filled with this powder. The aim of this study is to check the efficiency of such plates in the PAH elimination and verify the respect of the new 2011 regulation (2 μg/kg for benzo(a)pyrene, 10 μg/kg for the sum of benzo(a)pyrene, benzo(b)fluoranthene, benzo (a)anthracene and chrysene).

The productions of vegetable oil and methyl esters of vegetable oil lead to the generation of a lot of by-products. The purpose of this work was to study an alternative solution for a profitable use of vegetable oil by-products: anaerobic digestion. The potential for anaerobic digestion of 24 by-products was studied. The results show that most of oil by-products had a good capacity for anaerobic digestion. Then, the effects of the addition of oil by-products on the behavior of one reactor treating a mixture of grass, cow manure and fruit and vegetable waste and another reactor treating household waste were investigated. Most of the by-products tested improved significantly the production of methane indicating that the addition of by-products from oil production could represent a significant financial earning for the digester operators.Discussions are in progress involving oil producers and biogas plant operators to assess the opportunity of supporting the addition of by-products from oil refining in their facilities. A first evaluation of the costs and potential benefits of by-product treatment was performed. These costs should be reviewed in line with the increased development of anaerobic digestion and the expected benefits due to the digestion of by-products.

How to develop the use for animal feeding, of soybean produced in France? Comparison of two processes: flaking-cooking-pressing and extrusion- pressing Cooking-pressing or extrusion-pressing processes applied to soybeans produce partially deoiled cake used for animal feeding. These two processes were studied and compared with a view to implementation in an industrial unit. The various factors of hydrothermal treatment for conditioning the beans were studied at different scales (batch from 2 kg to 100 kg, and continuous flow at 100 kg/h) and the results showed the need for moist cooking to effectively deactivate the antitrypsin factors (FAT) while maintaining protein solubility. The extrusion-pressing was more effective for deoiling cakes than cooking- pressing (5.4 vs. 6.7 %) but less robust for deactivation of FAT (6.5 vs. 3.8 TIU/mg). The techno-economical study was carried out to simulate the crushing costs and net margins of both processes in a plant capacity of 20 000 t / year. It showed that the costs of both methods were similar (about 33 s/t). Gross margins were evaluated between 18 and 84 s / t in three valuation assumptions based on market price of oil, the mode value of the meal and the residual oil, the level of premiums GMO traceability and transport. The cooking-pressing process can also be applied to sunflower and rapeseed and versatility is an advantage to ensure continuous operation of the crushing unit in case of supply difficulties in soybean.
如何开发法国生产的大豆用于动物饲养?剥皮-蒸煮-压榨与挤压两种工艺的比较蒸煮-压榨或挤压两种工艺在大豆部分去油饼生产中的应用。对这两种工艺进行了研究和比较，以期在工业装置上实现。在不同规模(批量为2 ~ 100 kg，连续流量为100 kg/h)的条件下，研究了水热对大豆进行调理的各种因素，结果表明，在保持蛋白质溶解度的同时，需要湿煮才能有效地灭活抗胰蛋白酶因子(FAT)。挤压法比蒸煮法对蛋糕去油更有效(5.4% vs. 6.7%)，但对脂肪失活的效果较差(6.5 vs. 3.8 TIU/mg)。进行了技术经济研究，以模拟工厂产能为20,000 t /年的两种工艺的破碎成本和净利润率。结果表明，两种方法的成本相近(约为33 s/t)。毛利率在18至84 s / t之间进行了评估，基于油的市场价格、粕和残油的模式价值、转基因生物可追溯性和运输的溢价水平的三种估值假设。蒸煮压榨工艺也适用于葵花籽和油菜籽，在大豆供应困难的情况下，通用性是保证破碎装置连续运行的优势。

Fibre rich sunflower hulls have always been regarded as having a remarkable calorific value (5 000 kWh/t DM), very close to that of wood. Rising energy costs, emergent environmental concerns, and fitness for use of sunflower derived products have led to a growing interest in the dehulling of sunflower seeds prior to crushing, and burning of hulls in biomass boilers to yield process steam on site. This was made possible by prominent technological improvements in boiler technology. The torsional chamber technology exhibits good performances in full combustion of sunflower hulls, allowing for a high efficiency, a great flexibility, and a limited emission of pollutants. Yet, fumes may still have to be post-treated to ensure compliance with stringent restrictions in dust emissions. Being a robust and versatile technology, the torsional chamber is able to cope with a feedstock quality varying to a certain extent. The general design of a crushing plant fitted with a dehulling unit is impacted dramatically and becomes very sensitive to variations in hullability of the incoming seeds. Hull content and size of the seeds are correlated positively to hullability; moisture, density and oil content being correlated negatively. Hullability is affected mostly by environmental effects, cultivars being responsible for it to a lesser extent. Thus, hullability is impacted by upstream practices in plant breeding, field, and grain elevator management. Success in an efficient hulling strategy not only depends on the use of relevant technologies on processing plants, but also relies on knowledge of the seed and meal customer needs, as well as on concerted actions at various levels along the sunflower chain.

P.I.V.E.R.T. is an ambitious project of development of the 3rd generation biorefinery by 2020. Conceived around a technological complex with strict environmental criteria (aiming at obtaining a label HQE), P.I.V.E.R.T. federates all the national and main roads lifeblood, of the sector (some international partnerships are also under development). The major objectives of the P.I.V.E.R.T. project are: a valorization of oilseeds, proteins and lignocellulosic plant in its entirety (approach ‘‘entire plants’’) ; an operation in closed circuit on the level of water and energy exchanges, the platform providing for its own needs, in a logic of industrial ecology ; collection and valorization of a significant part of the CO2 produced by the activities of the refinery. Two strategies will be developed jointly: on one hand the development of ‘‘platform’’ molecules entering the traditional circuits of chemistry, on the current markets with the renewable character, in addition, the development of new molecules having new properties, thus giving access to new markets. Thanks to the research and development realized by researchers dedicated to P.I.V.E.R.T., the industrial partners will have access to a capable structure to develop, and to test demonstrators preceding future industrial production units. Certain technological bricks could be tested in a large scale industrial platform dedicated to operational integration of innovations. The development of programming technologies of refineries will give to P.I.V.E.R.T. the means to develop new innovative processes and will give to the industrials the possibility of modeling their future production units.

Sunflower meal is an alternative source of proteins for feedstuff but its high fiber content reduces the nutritional value. Different dehulling processes can improve the protein content and the nutritional value of meal. Partially dehulled sunflower meals with 32% and 36% of proteins produced in different crushing plants in France had been compared to non-dehulled sunflower meal (29% of proteins). The total French feedstuff production was simulated with a model including prices of raw materials observed during 2010-2011 campaign. The interest prices of the different qualities of sunflower meal compared to soybean meal varied from 0.43, 0.50 to 0.70 for 29, 32 and 36% of proteins content respectively. The 36% protein sunflower meal seems very well adapted to laying hens and ducks diets where 29% type should be more adapted to meat cows, sows and rabbits who need less concentrated diets. The new market for the 36 % protein sunflower meal type could notably help to provide local sources of proteins for high quality poultry production.

Energy consumption in oil mills is a major item of costs and a sensitive point in the production of biofuels. To improve their performance, industrials can recover lowtemperature heat thanks to a new technology of heat exchangers suitable for treating granular solid materials. Information about the energy requirements of the rapeseed crushing being not readily available, the article gives a detailed assessment of consumption items (per ton of seed: 263 MJ for preparation operations and 284 MJ for solvent extraction). These exchangers used as pre-conditioners saves about 55 MJ.t−1 of heat by use of steam condensates. We could go further in use of these devices on the one hand to recover heat from press cake and meal, and secondly to use recovered energy to dry and warm up the seeds before pre-pressing. In this configuration, the energy savings could reach 38% of current needs.

The 18th International Sunflower Conference took place in Mar del Plata, Argentina, in February, 2012. The key-points and evolutions of sunflower research were presented, in the fields of agronomy, physiology, genetics and genomics, crop protection, quality and markets. Major evolutions can be observed concerning the sequencing of sunflower genome, announced to be complete by the end of 2012, but also concerning the use of models and the progress in the studies on the interactions between varieties genetic pattern, environment and crop management practices. In crop protection aspects, the evolutions of the major pathogens, downy mildew and Orobanche cumana, have been discussed, as well as the breeding efforts for genetic resistances, or the advances concerning the herbicides tolerant varieties. Evolutions in oil quality aspects have been exposed too, such as varieties enriched in stearic acid, or tocopherols, or with low contents in saturated fatty acids.
