Seeking thermal process innovation for energy efficiency and reduced GHG emissions
PepsiCo seeks alternative heating methods to classical plate-and-frame heat exchangers to heat up liquid streams at a faster speed and/or higher efficiency, as well as lower the carbon emissions and greenhouse gases. Plate-and-frame heat exchangers invoke natural gas from steam and/or hot water that is generated on-site for the utility heating loop. In these heat operations, water is used as the heating medium, as with many industrial heating processes – water must be heated from ambient temperatures to near boiling for beverage pasteurization. To reach these temperatures, natural gas is burned to heat up the water loop and puts a significant load of carbon-emissions on the thermal process. Furthermore, heat exchangers often do not give immediate response for processes of high product flow rate. The response on water-heated heat exchangers is not fast enough to ramp up the flowing product to pasteurization temperatures to a reasonable tolerance. A heat-up time on the order of magnitude of minutes causes a significant delay in production on lines of commercial speed. Gas-fired boilers pose distribution losses in the system. Steam is generated at the central boiler(s) at typical plants with heating processes. The boiler output is routed to any unit operation that requires steam with hard piping. This results in non-negligible energy losses by means of heat conduction and frictional loss to the environment. In the case of pasteurization of liquids foods, steam indirectly applies heat to the process – steam is thermally exchanged with a water loop which bears the load of heating the pasteurization liquid. This results in low conversion to thermal energy, resulting in wasted natural gas usage and GHG emissions. In order to achieve higher production efficiency and better carbon footprint, novel technologies for heaters are desired. PepsiCo Beverages North America has set out goals for 75% GHG reduction by 2030 and net zero GHG emissions by 2040. For the longevity and sustainability of the environment, PepsiCo is highly interested in adopting and implementing emission-reducing technologies. A solution/application at any point in the heating distribution – whether it be an innovation to gas-fired boilers or a modular approach to heating – would be open for consideration. Proposed solutions should achieve one or more of the following objectives: • Faster heating ramp-up time compared to traditional heat exchangers. • Invoke equal to/less utilities than conventional plate and frame heat exchangers powered by steam generating boilers • Decrease distribution losses – apply energy with higher efficiency to the processing liquid • Net decrease in GHG emission from conventional natural-gas fired heating systems
Seeking natural colors for foods and beverages
PepsiCo is evaluating different natural color ingredients and technologies to replace Yellow #5, Yellow #6, Red #40, and Blue #1 for multiple food and beverage brands in order to address consumer demand. Specific challenges are in the Red #40 (food) and Blue #1 (food & beverage) replacers.
Seeking bio-based/biodegradable coating and adhesive solutions for flexible PHA films used in food packaging
We are seeking bio-based/biodegradable coating and adhesive solutions for flexible PHA films used in food packaging to achieve our sustainability goals of 100% recyclable, compostable, biodegradable, or reusable (RCBR compliant) materials and 20% greenhouse gas emission (GHG) reduction by 2030.
Navigation innovative system - a novel mathematical algorithm for route/path planning
A novel mathematical algorithm for route/path planning and monitoring, navigational software was created by researchers of the Jagiellonian University. The offer is an innovative mathematical approach based on area partition by time optimized trajectories. It offers new models based on wind/tidal stream/river current in marine/air (drone) navigation and trajectory planning, making use of perturbation (winds/currents/streams) instead of proceeding against them.
Super Porous Adsorbent of Heavy metals for Water Purification
ICN2 researchers developed an innovative super porous adsorbent with enhanced removal capacity toward heavy metal water contaminants. The material is fabricated by spray-drying and formulated into granules, and can be suitable for cartridges for domestic water purification applications. Moreover it can be regenerated by mild treatment.
Nanoparticles loaded with jasmonate to fortify and induce natural defenses in plants
A method for the production of calcium phosphate nanoparticles loaded with jasmonate for the induction of defense mechanisms in plants has been developed. The resulting product allows a controlled release of methyl jasmonate, ensuring efficient and long-term protection.
