Composting of Biosolids & Green Waste

North Londonry Township

North Londonry Township is located in Palmyra, Pennsylvania with a population of 7,000 people served by the borough. The township purchased a Brown Bear SC3610 compost turner through the local distributor Cleveland Brothers Equipment for the purpose of composting yard waste and leaves collected in the borough. The turner was mounted on an existing piece of equipment, a CAT IT24F which the borough uses for snow removal in the winter time. Pennsylvania DEP ACT 101 Grant funds were used for purchasing the equipment for infrastructure development. The Brown Bear was delivered in the fall of 2004 and was immediately put to use composting leaves from the fall collection. Starting once again in the spring of 2005 in early May, the 116 horse-power unit began breaking down the larger stockpiles of material and rolling them out into smaller windrow sizes of 10 ft wide by 3.5 ft tall. The Brown Bear is the only unit of its kind that has the ability to build its own initial windrows from a larger stockpile without the need of a bucket loader to form the windrows. The processing of 1200 yards per hour of material by the SC3610 requires only 1.5-2 man hours each time the piles are aerated. All the material is collected, processed, and given to the residents on the 2 acre asphalt pad. Town Road Master Earl Blauch picked the Brown Bear over competitive models for the simplicity of design, the unit’s ability to pile windrows edge to edge with no alley ways in between, and local support from a Authorized dealer.

Biosolids - Roswell, New Mexico WWTP

In 1996, Roswell's program won the Rocky Mountain Environment Association's Merit Award "for accomplishing out-standing results in biosolids management" and the New Mexico Water and Wastewater Association's Outstanding Achievement Award "for exceptional performance in sludge composting."  No bulking agent is added to the biosolids, which saves expense and reduces volume.

A Brown Bear paddle aerator is Roswell’s key material handling machine. Roswell's Brown Bear has worked 12 months a year, every year, since its arrival on site in 1985 and remains a highly reliable, highly effective tool. Its front-mounted 10-foot-wide, 0-140 rpm paddle-type auger does all the sludge mixing, aerating and turning.  Its 2.16 yard bucket and 12' lift does all truck loading and stock-piling. The machine's operator and a helper exchange the two attachments in less than 30 minutes.

 Biosolids & Yard Waste - Beatrice, NE WWTP

Beatrice's wastewater plant processes the wastewater flow of the city by primary settling and screening. The primary waste water is then mechanically dewatered and the sludge is taken to a compost site where it is mixed with yard waste – grass and shredded wood waste – and co-composted.  It produces a Class A finished compost by the new 503 EPA regulations. The Class A compost is unregulated for distribution and is used by city residents on their lawns and gardens.

Green Waste - Maryville, Missouri

The city of Maryville, MO has converted their landfill to a recycling and transfer station. Part of the recycling program includes composting of yard waste (grass and shredded wood). The city residents are allowed to bring their clippings and wood waste to the site. The city employees mix the ground wood with the grass clippings and compost the mix, using a farm tractor and a Brown Bear PTOPA35-10.5 compost attachment. The finished product is given back to the residents of the city for use on lawns and gardens.  For more information on the PTOPA35C series, click here.

ZOO DOO of Memphis, TN

The Memphis Zoo has solved the problem of handling animal manures and green wastes that every zoo has, without paying to landfill the waste products. In fact, their method - COMPOSTING - generates income for the zoo! Initially, getting a good mix and aeration with the bucket of their skid loader was impossible. However, they have solved their problem with the Brown Bear R24C-8 paddle aerator attachment, which mixes and aerates the windrows about every other day. The final compost product is screened and sold under the trade name of ZOO DOO.
