About the LCD biodigester

Description

The LCD biodigester is a machine that eats organic material. It is constantly digesting and can eat most types of waste—from harvest to post production.

You add your waste at any time by opening the door, putting in the waste, and closing the door. The LCD biodigester is fully automatic and takes care of the rest. All waste is converted to grey water that is safely discharged down the drain.

Power Knot has nine different machines with varying capacities.

How It Works

The LCD biodigester uses a series of processes in which micro­organisms break down biodegradable material in the presence of oxygen.

A medium inside the LCD biodigester — Powerchips — houses the microorganisms. In combination with our proprietary mixture of microorganisms and enzymes — Powerzyme — the digestion of organic products is accelerated. The output is grey water that is environmentally safe. You discharge this down the drain or use it to enrich your landscape.

The process operates aerobically — in the presence of oxygen — so there are no smells. A motor turns arms inside the LCD drum to mix the waste with oxygen and microorganisms. That turning is only a quarter of the time and is slow to ensure that the waste is not macerated and allows the microbes to digest the waste.

Installation

The LCD biodigester is typically installed where the waste is generated. This may be in the production area or the back of a room. You can install it outside, provided it is protected from the elements.

When the machine is placed near to where the waste is generated it improves efficiency by minimizing the labor to transport the waste, eliminating the need for plastic bags to contain the waste, and reducing the number and size of bins required to transport the waste.

You roll the LCD biodigester to its location and install the feet. Depending on the model, the machine needs warm water or hot and cold water, and ac power. The waste water output goes to a drain.

Depending on the model, an LCD biodigester can be installed in an hour or so.

 

Simple Operation

The LCD biodigester is constantly digesting the waste and you can add organic waste at any time. Simply open the door, throw in the waste, and close the door. In this way, you can view the LCD biodigester as a bottomless bucket. The LCD biodigester digests waste in a continuous process and operates without stopping.

Like our own stomach, you don’t feed the LCD biodigester only once per day; as the waste is generated you put it into the machine. This eliminates the accumulation of the waste, the need to take it out to a dumpster, and the bags you may need to do this.

The operating parameters of the machine are fully programmable and protected by a password. However, the default program works in the vast majority of deployments.

Weighing the Amount of Waste

Load cells on each corner of the LCD biodigester accurately weigh the amount of waste in the LCD biodigester, the amount that is added, and the amount that is digested. This data is automatically stored and reported graphically and numerically. The data can be viewed by the hour, day, week, month, and year.

As the operator adds waste into the LCD biodigester, the touch screen indicates how much more can be added. When the door is closed the LCD biodigester indicates with a bright LED when more waste can be added with a simple green indication. As waste is added, the indication becomes yellow when no more waste should be added and red if the operator overloads the LCD biodigester.

The LCD biodigesters are NTEP Certified. This certification provides assurance that the weight of the waste food that is measured and reported is true and accurate. This ensures compliance with regulations, prevents fraud, and builds confidence with stakeholders.

Capacity

The digestion rate of organic waste in an LCD biodigester depends on the waste type, the frequency of additions, and the duration of operation. Food waste, such as gummies and edibles that fail to meet quality standards, breaks down much faster than fully dried harvest waste, which takes significantly longer.

There is no fixed maximum amount of organic waste the machine can process in a day. When waste is added in equal portions throughout the day, the biodigester can handle a substantially larger volume.

Connection to the Cloud

The LCD biodigester can connect through its Ethernet port to a cloud server maintained by Power Knot. The LCD biodigester securely sends data about the operation of the LCD biodigester to the server and that data is retained for five years. The data includes the amount of 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 biodigester 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 biodigester at no charge to you.

Meet Compliance

The LCD biodigester provides cannabis cultivation and processing facilities with a compliant and sustainable solution for cannabis waste disposal. Adhering to Cal. Code Regs. tit. 4 § 17223, the LCD biodigester enables on-site in-vessel digestion, converting cannabis waste into a liquid byproduct that can be safely disposed of through standard wastewater systems. This process aligns with approved waste disposal methods, eliminating the need for costly off-site hauling while ensuring regulatory compliance.

Additionally, by reducing landfill contributions and supporting organic waste processing, the LCD biodigester helps businesses meet environmental sustainability goals and avoid potential fines or violations.

Global Features

Power Knot sells and supports its products worldwide and has installations in six continents and all of the world’s oceans. The LCD biodigester is fully certified for the US, Canada, and the EU with compliance information available on request. Small models (LCD-100 biodigester and below) have a universal ac input. Larger models are available with different ac supply voltages.

Power Knot products can be used globally to save money, improve operations, comply with local regulations and customer expectations, and reduce your carbon footprint.

Features of the LCD biodigester

The LCD biodigester is a fully automatic machine that disposes of most organic waste within 24 hours.

Constantly Digesting

The LCD biodigester is a fully enclosed automatic biodigester that breaks down organic waste on-premise. The LCD biodigester can be used to save money at a variety of facilities that have organic waste. The LCD biodigester  is designed, developed, and manufactured in Silicon Valley and will reliably digest for up to 15-25 years.
