Power Knot's on-site composting systems turn solid food waste into drain-safe wastewater

LFC Biodigester minimizes disposal costs, environmental footprint

The LFC from Power Knot is a biodigester that automatically converts solid food waste into drain-safe waste water. The operation is free of odour, slashes the costs for the disposal of waste, and greatly benefits the environment. Continuous bio-digestion allows food waste to be added at any time.

As one of six models currently available, the LFC-300 (shown here) can digest up to 500 kg (1200 lb) of organic waste per day. The unit can compost anything edible, including fruits, vegetables, raw and cooked meat, fish, cheese, bread, rice, and noodles. The compact stainless steel unit is intended for on-site installation at commercial or institutional food preparation and distribution facilities including restaurants, hotels, schools, supermarkets, hospitals, nursing homes, theme parks, corporations, military canteens, prisons, ships, island properties and food resellers.

In the machine, a horizontal agitator rotates slowly within the U-shaped vessel to maximize contact between solid food waste, bacteria, air, water and Powerzyme proprietary enzymes residing in porous plastic chips that remain in the vessel. The digestion process is aerobic (uses air) and exothermic (releases heat), raising the vessel temperature to about 42°C (108°F) which, along with automated infusions of hot and cold water, maximizes the rate of decomposition.

Liquids resulting from bio-digestion drain continuously through a screen along the bottom of the vessel, to an outlet at one end of the vessel and into any municipal drain. Since the grey water is rich in nutrients, it can also be plumbed into irrigation systems for lawns, shrubbery beds and crops.

Load cells supporting each corner of the LFC-300 transmit the weight of food waste added and digested, to an accuracy of ±1%, to a PLC which records and displays waste volume reduced, landfill gas avoided and other statistics, which can be viewed on a touch screen or accessed via the cloud. 

By eliminating solid food waste hauling costs and minimizing energy usage, these systems typically pay for themselves in six to 24 months, according to Power Knot. This system also minimizes the user's carbon footprint by precluding the emission of the 100+ tons/yr of CO2 that the equivalent waste would generate at a landfill, while eliminating the production of methane which is 84-times more harmful to the atmosphere than CO2. 

Five models of the LFC offer capacities from 20 to 1800 kg/day (45 to 4000 lb/day).

According to Power Knot customer Eddie Rodriquez, warehouse manager, Ace Natural Inc.,"Previously, we collected and wrapped outdated and damaged produce on pallets, stored it in the warehouse refrigerator, and shipped it weekly to a solids composting facility, at significant cost. Our LFC eliminates these costs and frees up valuable refrigerator space." 

Lindsey Llarazara, kitchen manager, Arthur I. Meyer Jewish Academy, said "We used to take out the trash three or four times a day. Now, we empty our garbage cans once a day. That allows us to schedule fewer garbage pick-ups in a week - most of the time, only one."

Composting Council Research Education Foundation releases report on soluble salts in compost

Composting Council Research Education Foundation releases report on soluble salts in compost

Compost contains a multitude of essential nutrients for plant growth, such as nitrogen (N), phosphorus (P) and potassium (K), and can also be a source of organic matter. However, recent concerns and criticisms have been directed toward composts with a high concentration of soluble salts. Soluble salts refer to the amount of soluble ions, such as calcium (Ca2+), potassium (K+), magnesium (Mg2+) and sodium (Na+), present in compost. Soluble salts are measured indirectly and cumulatively through electrical conductivity (EC).

Goudsmit builds magnets for iron-free carbon black

Goudsmit builds magnets for iron-free carbon black

Goudsmit recently built two magnets to be used for the production of iron-free carbon black by a large European manufacturer. These self-cleaning, rotating magnets remove iron particles as small as 30 microns from the very dry, poorly flowing conductive carbon black used for lithium-ion batteries.It is essential that this product is 100% metal-free, because metal particles would change the conductivity. In this line, the rotating magnets process at a relatively low capacity of 1500 kg per hour. If necessary, however, such magnets can process at  capacities of up to 40 m3 per hour.

BASF making products with chemically recycled plastics for first time

Dr. Stefan Gräter and Dr. Andreas Kicherer showing a sample of pyrolysis oil and thus produced plastic in front of the Steamcracker.

BASF is breaking new ground in plastic waste recycling with its ChemCycling project. Chemical recycling provides an innovative way to reutilize plastic waste that is currently not recycled, such as mixed or uncleaned plastics. Depending on the region, such waste is usually sent to landfill or burned with energy recovery. But chemical recycling offers another alternative: Using thermochemical processes, these plastics can be utilized to produce syngas or oils. The resulting recycled raw materials can be used as inputs in BASF's production, thereby partially replacing fossil resources.
