PepsiCo posted this Technology CallSeeking novel technologies for multiphase gas separation to enhance waste heat recovery during dehydration processesDehydration is routinely employed as a cooking process by the food and beverage industry. It uses significant amounts of energy and results in substantial lost heat to the atmosphere in the form of vapor clouds. The presence of atmospheric air, up to 30% by mass, in the air-steam reduces the possibility of waste heat recovery. As a non-condensing gas, it remains in a thin insulating layer at the condensate surface; this layer increases the partial pressure of the air and considerably reduces the heat transfer efficiency between the waste heat (steam) and any recovery medium. Separating the air from the steam significantly enhances the waste heat recovery opportunity. PepsiCo wishes to improve their waste heat recovery systems by implementing innovative technology to separate the desirable waste steam from the air-steam mixture.
Clariant posted this Technology CallSeeking Innovative Sustainable Biopolymers and Biorenewable Building BlocksSynthetic polymers are often used as thickening agents for liquid formulations. Already small quantities (< 1%) enable the formation of a gel network, which is most important for the correct application of the product. However, due to their persistence the reputation of synthetic polymers has deteriorated during the last years, which has increased the demand for natural alternatives. Despite the huge interest of the industry in green alternatives, successful candidates are a rarity, due to numerous technical and commercial hurdles. It is therefore most important to find partnerships with universities, start-ups, or well-established companies, which may lead to the development of new sustainable polymers for industrial and consumer applications.
IPI posted this Technology CallSeeking Technology Partner and Expertise to Produce Chitosan from Animal BiomassChitin is an important biopolymer that is converted to chitosan for use in many industries. The raw material from which chitin is extracted is typically shrimp/crab shells. Although chitin/chitosan is touted as a green material because it is recovered from waste crustacean shells, the global demand for it is rapidly increasing, whereas the farming or harvesting of crustaceans is environmentally unsustainable. There is thus, the opportunity to develop new processes for the production of chitosan from environmentally sustainable sources. The company has conducted preliminary research on the extraction of chitin from a particular type of animal biomass, and conversion into chitosan via chemical methods. The method has been designed to recover other valuable biomaterials, in addition to chitosan. The research has proven to be feasible and the company is now searching for partners with expertise in chitosan production to scale up this process on a semi-industrial scale.
