WINDROW TURNER EQUIPMENT REVIEW

ioCycle March 2005, Vol. 46, No. 3, p. 36

This second in a series of six articles, based on the new book, Modern Composting Technologies, takes a look at windrow turning equipment used for mechanical agitation of piles.

L. Diaz, G. Savage and N. Goldstein

IN TODAY'S modern composting world, there is “windrow composting,” a composting methodology, and then there is “composting in windrows,” typically as the second phase of a different composting methodology, such as in-vessel, or enclosed aerated static piles. In the former, all composting from start to finish is

AREPORT by a blue-ribbon commission of energy experts gives significant boosts to biomass electricity and biofuels as a strategy to meet U.S. energy needs.

TILLAMOOK DIGESTER PRODUCES POWER, FIBER AND INTEREST

BioCycle March 2005, Vol. 46, No. 3, p. 54

by-products from 2,000 cows in Tillamook County include 150 kilowatts/day going directly to the electric grid, plus digested fiber to Willamette Valley nurseries and compost from manure solids.

Laura Swanson

EVERY EIGHT MINUTES, a truckload of raw manure is pumped into the holding cells at the Port of Tillamook Bay's Hooley Digester (POTB) in Tillamook, Oregon. Then the truck is filled with liquid nutrient by-products from the digestion process,

Stephen Costello

FIFTEEN HUNDRED dairy cattle of all ages - from heifers to mature milk cows - have become the newest energy generators in Vermont. Blue Spruce Farm in Bridport began producing electricity on January 13, 2005 as part of a renewable

EVALUATING BENEFITS OF CLASS A BIOSOLIDS CAKE PRODUCTION

BioCycle March 2005, Vol. 46, No. 3, p. 41

A national survey of both small and large-scale wastewater treatment facilities shows varied approaches to reaching markets with superior methods that take the “biosolids out of the biosolids.” Part I

Sally Brown

FOR the vast majority of cases, the difference between Class A and Class B biosolids in terms of quality is solely based on pathogen concentrations. For exceptional quality materials, both Class A and B biosolids are required to meet the same standards with regard to metal concentrations. For pathogens however,

ODOR MODELING AT A BIOSOLIDS COMPOSTING FACILITY

BioCycle March 2005, Vol. 46, No. 3, p. 25

Analysis of alternative methods - agitated bed, aerated static pile and modified tunnel - show that properly applied facility configurations with biofiltration would reduce odors to acceptable levels at Colorado site.

Todd O. Williams and Stacey Servo

ODOR GENERATION and impact on surrounding communities is a significant issue facing existing and proposed composting facilities. Left unchecked, odor impacts can lead to a facility shut down. Odor modeling can be used to evaluate

RECYCLING ENTREPRENEUR: THE NEXT GENERATION

BioCycle March 2005, Vol. 46, No. 3, p. 24

An adolescent ethic is turned into a business fit for adults - “a fun business with positive personalities for the community instead of negative ones.”

Bill Lord

FOUR YEARS AGO, in the magazine In Business, (“sister” publication to BioCycle), I chronicled the emerging career of a recycling entrepreneur - James Park, a 17-year-old high school senior, owner and CEO of Park's Environmental Recycling. He had begun the recycling business at age 11 and in the ensuing years grew the

LEGISLATURE CONSIDERS BILL TO SET GOAL
OF 50 PERCENT RECYCLING BY 2009
Many factors are working together to “make us feel pretty optimistic that we're going to see an increase in recycling,” says Deputy Director Sue Inches of the Maine Planning Office. Markets and prices for recyclables are strong, as the Maine legislature assembles a bill to achieve a 50 percent recycling goal by January 1, 2009 - and also reduce MSW generation by five percent. Other factors

PREVENTING PHOSPHORUS OVERLOAD WITH SPECIALTY COMPOSTS
Agricultural Research Service (ARS) agronomists are reported to be studying “environmentally friendly composts that help keep phosphorus from seeping into water supplies.” Rufus Chaney and Eton Codling - with the Animal Manure and By-Products Laboratory in Beltsville, Maryland -have been investigating inexpensive methods to make phosphorus less water soluble, or to increase the ability of manure, biosolids and composts to hold onto the phosphorus. They found that composts high in iron could markedly help the manure and compost retain phosphorus, since both iron and aluminum oxides increase adsorption of
