A Case Study

The Challenge: Large facilities that house and feed over 1,000 individuals with a staff of an additional 1,000 that operate 24/7. The challenges are that this type of facility must house and feed these individuals 365 days a year. They generate an extreme amount of organic waste in their personal living facilities including shower areas, but especially in their cafeteria and kitchen areas where large amounts of food waste are funneled down drains that lead to Grease Traps.
