GEA Insights
GEA and Pulmuone honor generations of cold noodle craftsmanship
When plant-forward South Korean food producer Pulmuone brought GEA the challenge of developing a modern spin on the traditional chewy cold (naengmyeon) noodle, GEA’s R&D experts were up to the challenge. They helped develop what is now a commercial hit produced with less water and electricity than previously existing methods. The result is also true to the traditional origins of the dish as well as Pulmuone’s health, well-being and sustainability roots.
Pre2Fuel: Cleared for takeoff
GEA's innovative process marks a milestone in the pretreatment of biofuels such as hydro-treated vegetable oil and sustainable aviation fuel. By eliminating the bleaching process, manufacturers benefit from significant savings potential: over 50% lower operating costs and up to 12% less CO2 emissions.
