Grease Guardian Exceeds Japan’s Grease Interceptor Standard
We are excited to announce that Grease Guardian has received approval under the SHASE-S 217 standard, a prestigious recognition from the Japanese Grease Management Standard for Grease Interceptors. This approval is a testament to the high efficiency of Grease Guardian’s grease management systems, meeting rigorous standards for grease interception in commercial kitchens and food service establishments.
Understanding SHASE-S 217 and It’s Importance
The SHASE-S 217 standard, a Japanese benchmark, evaluates the effectiveness of grease interceptors in capturing grease from wastewater. To receive this approval, a system must meet stringent efficiency requirements, with a minimum interception efficiency of 90%. Products that fall below this threshold do not qualify for approval. This certification is essential for systems used in environmental buildings across Japan, where high standards for sustainable and eco-friendly operations are upheld.

The chart above illustrates the relationship between inflow frequency (number of times tested) and interception efficiency. Grease Guardian’s performance surpassed the SHASE-S 217 requirements in both individual flow and cumulative retention efficiencies.
Here’s a breakdown of what this means:
Individual Flow Efficiency: The blue line on the graph represents the efficiency of Grease Guardian at each inflow instance. The SHASE standard requires each flow to have an efficiency of 90% or higher. Grease Guardian consistently exceeded this, achieving a retention efficiency of 99.4% or higher for each inflow instance.
Cumulative Efficiency: The red line represents the cumulative retention efficiency, which is even more stringent, with a required threshold of 95% or higher. Grease Guardian met this cumulative efficiency benchmark with flying colours, consistently achieving over 99.4% across multiple tests.
This chart replicates the original SHASE graph and highlights Grease Guardian’s exceptional efficiency, with both individual and cumulative retention rates surpassing required thresholds. This performance ensures our systems provide sustainable, eco-friendly solutions for managing grease-laden wastewater.
