Client’s Requirements

In 2019, ENSO Solutions, a leading Medical Marijuana Waste Management Provider in Oklahoma, obtained one of the state's earliest operational permits. Waste regulation is of utmost importance within the medical marijuana industry, driving ENSO's focus. Composting, chosen due to the substantial organic waste from the cannabis sector and aligned with Oklahoma's disposal regulations, became central to their eco-friendly waste management mission. Amid evolving legal and public perceptions of the cannabis industry, ENSO seeks to both align with state regulations and exemplify responsible waste management practices. By meticulously managing the containment, secure handling, and eco-friendly disposal of significant volumes of organic and potentially hazardous waste originating from cultivation processes, they are helping to cast the industry in a positive light. To compost effectively, ENSO needed an enclosed in-vessel system capable of operating efficiently within limited spaces while accommodating substantial material volumes. Easy accessibility and complete visibility during the composting processes was essential for allowing a close watch over the degradation of diverse, often dry-consistency materials. ENSO envisioned an automated and streamlined composting process as a key driver of operational efficiency, enabling their team to allocate more time to core business activities, including nurturing client relations and fostering company growth.

Our Solution

Enso Solutions opted for GMT's 20’ Intermodal Earth Flow system, capable of processing approximately 1,500 pounds of green waste daily. Housed in a compact warehouse, the system's innovative design includes an outdoor biofilter to effectively neutralize odors arising from the composting process. Enso highly values the compact form and small footprint of the Earth Flow, as it allows them to closely monitor each stage of the composting process.
A thorough analysis of each unique feedstock's nutrient profiles was conducted by GMT specialists, the results of which led to tailored recommendations for material adjustments and processing refinements. Since the installation in 2021, Enso's operations have thrived, prompting exploration of a boutique bagged finished compost product to further boost company revenue. Enso Solutions' adoption of composting reflects a proactive and sustainable approach to waste regulation and community engagement in the medical marijuana industry
