Hi all,

I was thrilled with the recent National Waste policy released by Minister for the Environment Mr Phil Hogan T.D. as now all households over a certain Urban population presumed to be over 1500 will have a Brown bin within the next 4 years.

This will allow households to divert their food waste from their Normal land fill destined waste bin, and so spend less on presenting it for collection as these costs are destined to continue to increase.

This is an excerpt from a blog by Ms Holly Elmore in the USA a passionate activist in food waste diversion from landfill and applauder of the landmark efforts being made here by you in Europe.

” With strong European success, anaerobic digestion for commercial and residential food waste is gaining momentum in the U.S.The technology has solid  U.S. traction at municipal water treatment facilities and on-farm, yet is a frontier for food waste.

Predominately enclosed in a facility, anaerobic digestion systems tend to make the permitting process easier where citizens are concerned about smells generated at traditional composting operations. A challenge is if the state regulations do not contain anaerobic digestion provisions, leaving regulators perplexed as to the permitting process.

In layman’s terms, anaerobic digesters decompose organic material in a closed anaerobic (without air) environment where the methane gas produced is captured for energy use.  Each system has its own “recipe,” including food waste, yard trimmings, FOG (fats, oils & grease from kitchen operations) and other organic material.  After the energy is extracted from the organic material, digestate remains as the system by-product.  With further “curing” the digestate is often used as a soil amendment.

incorporate air into the process

Traditional windrow composting uses an aerobic (with air) system where the piles are turned, thus not producing methane gas.  The energy component inherent within food waste remains within the compost, providing nutrients for the soil’s microbial community.
With the pending shift in foodservice disposable items to compostable products coupled with zero waste programs, the food waste feedstock may soon include a significant portion of man-made products.”
