Collaboration Leads to Upcycled Oil with Unique Profile

A company growing mint leaf for tea and beverage applications was dealing with several tons of waste. While processing the mint leaf small fragments of leaf “fines” and bits of stem accumulated. Not suitable for their beverage applications, these fines and stems were a significant waste stream and they were searching for an affordable waste removal option to ensure the growing volume of material didn’t impede the growth of the company, either through cost of removal or the space it occupied. 

Essex heard of their problem and developed a custom distillation process to utilize the fines and stems to produce a valuable mint oil.  This was a win-win, as the mint beverage company was able to valorize a waste stream and Essex was able to add a sustainably produced upcycled material to their palette.  After distillation the remaining waste from the fines and stems can be spread back onto mint fields, enriching the soil. 

Rightly named Peppermint Leaf Dust oil, it possesses an earthy, herbal organoleptic profile and adds depth and complexity to mint oil blends while being produced at a price point lower than conventional US grown mint oils.  

Peppermint Leaf Dust oil has become a remarkable tool in the Essex palette, having been utilized in several winning formulas with great customer feedback.  We’ve expanded to include Spearmint Leaf Dust oil and are seeking to increase production of both varieties.  Thanks to its unique sensory profile and valid marketing claims we foresee continued growth in the use of these oils, both as powerful blending tools and complex standalone materials.
