Zero Food Waste Program
 

Since 2020, Pulmuone has been gradually introducing microbial food waste treatment systems as part of our efforts to reduce food waste. These microbial treatment systems use harmless microorganisms to fully decompose food waste. Installing this system is expected to reduce waste treatment costs by 63% annually per business site. As of April 2025, approximately 120 microbial food waste treatment systems have been installed and are in operation at concession stands, rest areas, and meal service sites.

Food Waste Resource Circulation Program

Pulmuone is implementing a resource circulation program to utilize recyclable food waste from manufacturing processes as animal feed and biodiesel raw materials. Starting with the Pulmuone Foods Eumseong Tofu Plant in 2020, as of 2024 a total of six manufacturing sites— Pulmuone Foods’ Eumseong Tofu Plant, PPEC Eumseong Fresh Noodle, PPEC Eumseong Uiryeong, Pulmuone Green Juice, PPEC Global Kimchi, and Pulmuone Kibun—have
registered plant-based residues and used cooking oil under the Ministry of Environment’s Resource Circulation Recognition System. In these certified sites alone, 7,768 tons of food waste (as of 2024) have been recognized as alternative resources and recycled, and Pulmuone continues to expand the scope of sites applying the resource circulation program.

Collaborating With Suppliers to Reduce Food Waste

Food waste often results from product defects caused by deviations from standard specifications or packaging issues during production. Pulmuone addresses this by partnering with suppliers on joint R&D to identify the root causes of such defects and implement corrective measures. Through the introduction of new equipment and
continuous product quality improvements, we have steadily reduced the defect rate, thereby minimizing food loss and waste generation.
