Experience combined with an ear attuned to the changing environment of foodservice….

According to the U.S. Chamber of Commerce:                                           When we speak today of going green, we generally refer to something broader than global warming. We usually are referring to a heightened awareness of using the Earth's resources more efficiently. The term today includes efforts to conserve our natural resources, reduce our contributions to landfills, and reduce pollution generally. Going green, then, can be summarized by the mantra "reduce, reuse, recycle"-- which means reduce waste, reuse what you can, and recycle what you can't.

Green is the design, commercialization, and use of processes & products that are feasible & economical while: Reducing the generation of pollution at the source. Minimizing the risk to human health & the environment.

We cannot solve the problems that we have created with the same thinking that created them in the first place.

-Albert Einstein

What is L.E.E.D.?

LEED is an internationally recognized green building certification system,  providing third-party verification that a building or community was designed and built using strategies aimed at improving performance across all the metrics that matter most: energy savings, water efficiency, CO2 emissions reduction, improved indoor environmental quality, and stewardship of resources and sensitivity to their impacts.

Developed by the
U.S. Green Building Council (USGBC), LEED provides building owners and operators a concise framework for identifying and implementing practical and measurable green building design, construction, operations and maintenance solutions.

LEED is flexible enough to apply to all building types – commercial as well as residential. It works throughout the building lifecycle – design and construction, operations and maintenance, tenant fit out, and significant retrofit. And LEED for Neighborhood Development extends the benefits of LEED beyond the building footprint into the neighborhood it serves.

The Problem of Food Waste

Almost half of our food is wasted in the United States. How does this happen?

 In the US and as a result, uneaten food is the single largest component of municipal solid waste. In landfills, food gradually breaks down to form methane, a greenhouse gas that’s up to 86 times more powerful than carbon dioxide. 

With installations globally, Power Knot offers the most technologically advanced machines available today and is the market leader in biodigesters. Our LFC biodigesters are proven, available today, have been in reliable use for many years, and offer a payback period typically of less than two years. Power Knot is a profitable company that designs, develops, and manufactures its LFC biodigesters in Silicon Valley, California. For more information, access www.powerknot.com.
