Power Knot LCD Liquid Compost Digester

Changing Waste Forever

The Liquid Compost Digester (LCD) was born from the idea of coming full circle in the growth cycle, from seed back to earth.

Innovating For the Future

Our cutting-edge Liquid Food Composter (LCD) has been used for close to a decade to eradicate food waste. Our natural desire to evolve, coupled with the explosion of the growing industry, led to the creation of the Liquid Compost Digester (LCD) and the results have been extraordinary. It has been a real adventure to modify, test, and implement the LCD. We regularly hear the phrase "this is a game-changer for the industry" and it couldn't be more accurate.

The LCD is here to change how this industry deals with green waste. Constructed from all stainless steel with a mirror finish, the LCD biodigesters are built to last with the lifespan of each machine expected to be 15 to 25 years.

The LCD uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen. The environment of the LCD, with our proprietary mixture of microbes and enzymes, accelerates the digestion of most plant products within 24 hours. The output is greywater that is environmentally safe. You can discharge this down the drain or use it to enrich your landscape.

The LCD by Powerknot comes in 7 different sizes with different voltage options on the smaller models.

Available sizes:

• LCD-50 - 50 lbs. of waste per day (Available in 120 volt or 208 Volt)
• LCD-70 - 70 lbs. of waste per day (Available in 120 volt or 208 Volt)
• LCD-100 - 100 lbs. of waste per day (Available in 120 volt or 208 Volt)
• LCD-200 - 200 lbs. of waste per day - 208 Volt (example picture shown here)
• LCD-300 - 300 lbs. of waste per day - 208 Volt
• LCD-500 - 500 lbs. of waste per day - 208 Volt
• LCD-1000 - 1000 lbs. of waste per day - 208 Volt

All models have a 6 ft. power cord except for the LCD-1000 which has a 10 ft. power cord.

Simple Operation

The LCD is constantly digesting the waste and you can add plant waste at any time. Simply open the door, throw it in, and close the door. In this way, you can view the LCD as a bottomless bucket.

The motor on the LCD won’t run while the door is open for safety. Your operation can be streamlined because large bins and plastic bags are no longer needed to hold plant waste. Instead, smaller bins are used that help avoid injuries to employees

All configuration, indications, reports, and statistics are available through the touch screen. The operator doesn’t need to use the touch screen and for most applications, the default settings work well. All configurable parameters are protected by passwords.

Maintenance

The LCD is designed to be as maintenance free as possible. Basic maintenance could not be easier and is very minimal. Yearly check-ups are recommended and we have a vast network of service staff worldwide to support the LCD.

Support

We offer 24/7 support through our cloud software which monitors almost every aspect of the LCD. Temperatures, amp readings, warnings, and the overall weight of the machine can be viewed from your desktop or mobile phone. Automated alerts can be sent to either your phone, or email should there be any issues with the LCD, or if you just simply want to log on to see how much waste has been digested that day.

Installation

The LCD can be installed, commissioned and your staff fully trained in most cases in one day.

Connection to the LCD Cloud

The LCD can connect through its Ethernet port to a cloud server maintained by Power Knot. The LCD securely sends data about the operation of the LCD to the server and that data is retained for five years. The data includes the amount of plant waste digested hourly, daily, weekly, monthly, and yearly; the number of times the door is opened in these periods, and the amount of CO2 diverted from the landfill during these periods. If you have multiple machines, you can aggregate the data into a single report.

Remotely, you can view the health of the system including all diagnostics and when the LCD requires scheduled maintenance. You have access to view and manipulate the data from any computer, tablet, or smartphone anywhere in the world. This access is available as long as you own the LCD at no charge to you.

The LCD Cloud can send you an e-mail with daily, weekly, or monthly statistics, alert you when it is time for periodic maintenance, and send an e-mail if there seems to be a problem with the LCD. For as long as the LCD is under warranty, Power Knot can also monitor your LCD at no charge.

Our digesters were developed for food waste over a decade ago, and have been instrumental in the foodservice industry. With the explosion of the legal growing industry we saw the need to address the waste problems that would inevitably be created, and in 2018 set our R&D team in Silicon Valley to the task of converting our LCD to the digestion of grower waste. The results have been exceptional. We were guided by long-established growers with over 30 years of experience in the industry to fully understand all the waste issues and allow us a better awareness of the industry and plant overall.
