Cannabis Waste Management with the LFC biodigester

In the ever-evolving cannabis industry, waste management remains a persistent challenge. One leading marijuana harvesting facility in Los Angeles has adopted an innovative approach to handling harvest waste by incorporating the LCD-500 biodigester into its operations. Power Knot provides the LCD biodigester, a stainless steel machine designed to efficiently transform cannabis harvest waste into reusable water.

Navigating Regulatory Compliance

Cannabis cultivation and processing facilities must adhere to stringent regulations, such as Waste Management, Cal. Code Regs. tit. 4 § 17223, which dictates the approved methods for disposing of cannabis waste:

  1. On-premises composting of cannabis waste.

2. Collection and processing by a local agency, franchised waste hauler, or permitted private waste hauler as part of an organic waste collection route.

3. Self-hauling cannabis waste to a landfill, composting site, in-vessel digestion facility, or grind operation facility.

Additionally, regulatory bodies require meticulous tracking of waste, including batch ID, type, and weight. This information must be recorded in paper or electronic manifests, entered into the state’s track-and-trace system, and made available for audits.

However, many offsite waste management facilities refuse to accept cannabis waste due to cannabinoid remnants, and transportation costs for disposal often make compliance impractical. Given these challenges, on-site waste management solutions are increasingly recognized as the optimal choice.

A Smart and Sustainable Solution

LCD biodigesters are revolutionizing the way cannabis facilities handle green waste. This advanced system leverages microbial processes to break down biodegradable materials in an oxygen-rich environment. Within the controlled setting of the LCD biodigester, a proprietary blend of microbes and enzymes accelerates decomposition, reducing most plant products into environmentally safe grey water in just 24 hours. This grey water can be safely discharged, used to enrich surrounding landscapes, or reused to irrigate the crops.

As waste is placed into the LCD biodigester, it is automatically weighed. The weighing is NTEP certified, being the only digester in the world that has this important compliance requirement. The weights are accumulated and displayed on the color touch screen and on the cloud interface, making it possible to create reports for regulatory bodies instantly.

Key Features of the LCD Biodigester

  • Decomposes plant and other biomass waste directly at the facility.
  • Provides real-time statistics on usage and digested plant waste.
  • Incorporates diagnostics and a service schedule for optimal performance.
  • Continuous 24-hour digestion process without the need for manual emptying.
  • Durable stainless-steel construction with an expected lifespan of 15 to 25 years.
  • NTEP certified and fully compliant with state regulations for the tracking of the weight of the waste.

The LCD-500 biodigester, which was installed at the facility in Los Angeles and commissioned in 2021, has played a crucial role in digesting harvest waste efficiently with no residual THC or CBD. As such, it has saved the facility significant money with a payback of less than a year.

Shaping the Future of Cannabis Waste Management

The LCD biodigester is proving to be a game-changer for cannabis harvesting facilities looking to manage waste effectively. By ensuring regulatory compliance, reducing costs, and promoting sustainability, this cutting-edge technology is setting new standards in the industry. With solutions like the LCD-500, cannabis facilities can look forward to a future where waste management is no longer a burden but a seamless, eco-friendly process.
