Martin Energy Group and Martin Construction Resource knew there was a better Digester. The problem, it had not been designed yet.

By working as a united team we were able to Design and Build.

Why the EM-21 stands out above the rest

1) In-ground – safe, easy maintenance and clean out
2) Cleanout without removing the cover!!!
3) Enables easy crust control if needed
4) Easily change mixer props with through roof hatches
5) Flexible, double-membrane cover
6) Proven heating coil system – no external heating years later
