What we do

Power Knot provides safe and economically sound solutions for commercial, industrial, and military customers globally seeking to reduce their carbon footprint. Power Knot has two related businesses:


• to reduce the expense, inconvenience, and mess of disposing of food waste that would otherwise be hauled to a landfill where it would degrade into methane (LFC)


• to improve energy efficiency, reduce operating expenses, and enhance reliability of air conditioning and refrigeration systems (SRA)


Our technologies are proven and available today, have been in reliable use for many years, and offer a payback period typically of less than two years. For information on how we sell our products and support our customers click here.
