摘要

Getting the right equipment for any kind of facility is one of the most important (and expensive) decisions a plant designer can make. And this is as true today as it was two decades ago when the late Steve Apotheker looked into what it took to engineer the nation's largest municipal solid waste (MSW) composting plant. The facility in question, a 600-ton-per-day facility was owned by Portland, Oregon's regional government, Metro, and built and operated by Riedel Environmental Technologies, Inc. Not only was the plant the first in the U.S. to be publicly financed by tax-exempt revenue bonds (over $31 million in total), it was the first of its type to use DANO MSW composting technology in the country. The DANO system is made up of several large drums in which the soft material from the MSW stream is gently tumbled against the harder, inorganic items (e.g., bricks, wood, concrete), slowly breaking down the organic material, allowing for easier screening of the inorganic material. The process, which had been in use in one form or another around the world since World War I, reduces the size of the organic materials, ultimately benefit-ting and accelerating the composting process, by optimizing the rate of microbial digestion.
