Municipalities and private contractors in New Jersey and Connecticut are grinding their way through the whole trees and roots uprooted by the October hurricane.

Sandy took out a record number of trees in New Jersey. Local utilities reported more than 113,000 destroyed or damaged trees. As in New York, an all out effort is underway to collect the vegetative storm debris and reuse the material where possible.
“Everything that came down was big,” says Kevin Downes, owner of Downes Services in Hawthorne, New Jersey. “Whole root balls just came out of the ground. It was five times as bad as last year’s Halloween snowstorm that damaged about 75 percent of the trees in our area.”
Since Superstorm Sandy, Downes’ company has been collecting debris off the streets for many municipalities. “It is a challenge,” he says. “So much more time and equipment is needed to deal with each of these big trees. It takes days and a tremendous number of man hours to take trees off houses and power lines and then deal with the stumps.” To manage the huge volumes of debris, material is hauled to the municipalities’ recycling centers where it is ground and made into a finished landscaping product that will be given away to town residents next spring. “There is just no place to go with it,” Downes adds. In one town, it has been working on removing the stumps of 188 uprooted trees. “It is a big process that does not happen very quickly,” he explains. “ We are estimating at least 4 to 6 months more worth of work.”
Downes Services operates its own recycling center in Hawthorne, where it processes tree debris into mulch products. Normally the company sells about 100,000 yards of mulch a year. “This year we will probably double that because of the volume of material from the storm,” Downes notes. The company uses two Diamond Z grinders, a Model 1360 tub grinder and a Model 5000 horizontal grinder, to process the debris at its own site, and the other locations. The equipment has been running 10 to 12 hours a day. “The grinders do a really nice job,” he says.
South Jersey Agricultural Products, Inc. (SJAP), based in Elmer, New Jersey, has been in the wood recycling business since 1985. Lately, SJAP has been processing tons of debris left behind by Superstorm Sandy. “We are hauling material to our site, and then sort it as it comes off the truck to remove contaminants such as tires and tire rims,” notes Ed Stella, owner of SJAP. “We’ve also been contracted by a New Jersey municipality that has a wood debris transfer station to do the grinding in their yard. We bring our track-mounted Peterson 6710 horizontal grinder and a crew there to do the processing.” The unit was customized with a bigger engine; material is ground to roughly 2-inches.
SJAP has a bagging facility at its yard in Elmer, where it packages mulch, colored mulch, topsoil and other products for brokers who supply the big box stores. It sells some products under its own brand. “This is the time of year we are very busy filling bags for the spring season, so having this flow of mulch was good timing for us,” adds Stella. The company uses Colorbiotics’ Sahara colorizing equipment. “Between the topsoil, colored mulch and straight mulch, we supply several million bags a year to the brokers and our own network,” he says.
Harvest Power, which has 11 sites in New Jersey, is also processing tree debris from Superstorm Sandy. The material is ground, stockpiled and aged to make mulches and composted soil products. “This was a massive storm that caused a lot of damage,” says Paul Sellew, Harvest Power CEO. The company has brought in extra grinders and loaders and has been grinding material nonstop since the winds died down. It has been working with certified contractors from outside the region to deal with the staggering number of trees.
Wood reaching its facilities is checked to determine the quality and type of material. Almost everything is getting ground. Best efforts are made to process the material and turn it back around for sale, or store it for the spring season. Harvest Power anticipates a lot of people will want to restore their landscapes come spring, creating demand for additional loads of its mulches and soil products. Everyone is working extra hard to deal with permit caps and occasional space constraints. In some cases, sites that are not logistically close to the damaged areas will be needed to hold the material.
Harvest Power recently purchased GreenCycle’s composting and mulch facilities in Connecticut (three in total). Its operation in Fairfield is close to the shoreline, which was pretty heavily hit by Superstorm Sandy. “We received an extra 5,000 tons of wood debris just from one town,” says James Repenning of GreenCycle/Harvest New England. “We also have been bringing our grinding equipment to towns along the shoreline. In most cases we’ve been able to use their existing recycling yards to process the material.”
GreenCycle purchased a new Morbark 1300B tub grinder right after Sandy hit. The company has always used Morbark tub and horizontal grinders. Its new machine is equipped with a wider mill that features a proportional feed. “The previous model would feed full speed, stop the tub completely to let the motor recover, then return the tub to full speed,” explains Repenning. “On this one, the computer system slows down or speeds up the tub to keep the engine running in an ideal range. This machine has been able to handle the large oversized material and long trunks better than our other tub grinders. We’ve been able to almost eliminate the need for the grinder operator to get out of the cab and use a chain saw to make the pieces smaller. That save us time, and more importantly, eliminated a lot of dangerous chainsaw work.” This has been a huge benefit as Superstorm Sandy uprooted whole trees, including the root ball, whereas the snowstorm that hit around Halloween of 2011 was primarily branches and tops.
