Title: Re: [GreenYes] Re: Growing Global Interest in Food Waste Disposers

Kendall-I would love a copy of the WSJ article.

Dan- It seems to me that the problems that biosolid systems are having in this country are more a function of a dilapidated or under-sized infrastructure and that this issue calls forth the need to seriously examine that infrastructure. Also, in your climate backyard composting is probably a bit more doable than in northern climates like Philadelphia, Boston, Chicago, etc. In addition, in many cities people don’t have space, literally. Here in Philly the majority of backyards are postage size. Finally, in studies I’ve seen, while the residential food waste component is high, the commercial and institutional fraction is much higher. Short of daily collection of roll-out carts, what is a Hilton Hotel supposed to do with their 2,000+ pounds of food scrap and sauces? 

I’m advocating (and Kendall and I have talked about this often) for a very careful and thorough analysis of all the options for really solving this problem, especially for the commercial sectors. If it means that cities need to look at renovating with $200 million bond options or privatizing their sewer systems, or whatever, then so be it. Certainly, if the Bay Area is struggling the way you say it is, this process must already be underway. I would hope all the Waste-Heads their are looking to be a part of the solution.

I have read several articles in the local press about how these plants are so maxed out that they are sometimes forced to dump untreated sewage into streams that drain to the Bay.  In late January one major sewage release in Marin County amounting to millions of gallons was one of the lead stories on the evening news for a couple of weeks.  Following that spill, lots of dead shorebirds were found in the area, although no conclusive link was established.  Also, sewage treatment facilitiy operators are advising customers via mailings never to put grease into the sewage system at all, since it creates pipe blockages not to mention lots of Biological Oxygen Demand.

I've done it for decades, and it's very satisfying, especially when combined with growing food in the enriched soil you get when you actually use the finished compost.  My soil horizon in the food garden is now about eight inches deep after fifteen years of soil amending with dozens of cubic yards of humus.  I'm also taking carbon that used to be in the air and putting it into the soil, where it nourishes the soil critters and fungi that help plants grow.  The soil is much easier to work than the heavy clay that I had to start with; no clods at all, and it holds water like a sponge.

In particular, it noted the experience of several cities that have intentionally opted for disposer-based systems for food scrap management.
