MUFFIN MONSTER button Sewage Grinder pinback Irvine wastewater treatment 1990s
This is a previously-owned, white button that says, “Muffin Monster.” Distributed by JWC Environmental, it measures approximately 4 inches in diameter and is in great shape…
Spanning 45 years, the Muffin Monster has come to symbolize uncompromised performance and technical leadership in municipal wastewater treatment. At one of the first wastewater treatment plant installations in Irvine, California a plant operator watched the grinder rapidly devour “muffins” and turn them into harmless tiny pieces and exclaimed – “Wow – what a Monster!” And the legendary Muffin Monster brand name was born.
