Matt Smith wonders what he would be doing today if his company wasn’t selling colored mulch. “I’d probably not still be in the mulch business,” says Smith, chief executive officer of Smith Creek, Inc., in Borden, IN.

Smith Creek got into the wholesale colored mulch business in the late 1990s and today its bagged colored mulch outsells natural mulch by as much as 95 percent. Bulk sales of colored mulch are 85 percent higher than natural mulch, Smith reports.

Other mulch manufacturers report similar success selling colored mulches, particularly browns, reds and blacks.

Fortunately for mulch producers, there is a wide variety of options to chose from when selecting a colorant system. Those options include stand-alone coloring systems some of which are transportable, horizontal grinders with optional or dedicated coloring systems, and injection pump systems that can be adapted to existing tub, horizontal, trommel screens and other mulch producing equipment. Sophisticated electronics on some units help minimize water and colorant usage.

Many colorant equipment manufacturers, as well as other companies, offer a wide range of colorants in liquid or powder/granular form; liquid-based colorants are most commonly used.

“In its simplest form, it’s like baking a cake,” says one longtime industry expert when discussing colorizing mulch. “You’re just mixing contents and stirring it around so colorant is absorbed into the material. There’s a wide variety of delivery systems and it just depends on how sophisticated you want to be. It also depends on your volume and economics…”

Understanding those delivery systems — and the actual costs and benefits associated with each — is crucial.

“I would say the most critical thing mulch producers can do is to contact an industry expert and let them sit down and talk them through the process,” advises a spokesman for a leading colorant equipment company.

That process includes discussing the various types of colorant systems, the market being served, production capabilities, how many colors to be produced, the wood source and the actual cost of each type of system.

For example, adding a colorant pump and a spray bar to inject the color to an existing grinder may be a cost-effective solution for some mulch producers, especially those who want to test the market or who have excess capacity on their grinder. However, some of those cost savings may be offset by higher colorant and water usage compared to a stand-alone system. The greater moisture content in bagged products, for instance, could result in higher freight costs. Also essential is to have an operator closely monitoring the equipment to avoid over-application of colorant if the production rate should drop due to equipment wear.

Manufacturers of stand-alone colorant systems say their equipment offers more control, accuracy and consistent application to produce a superior product.

Adding a pump injection system with spray bar to an existing grinder or trommel is the least expensive option from a hardware standpoint, running about $10,000.

That was the option that Scott Ledford decided to take when he decided to get into the mulch business about six months ago.

“I think it’s the most efficient way for my operation,” says Ledford, who launched his Metrosite Forestry Products in an effort to divert C&D waste, waste pallets and other such materials from the landfill and to find a viable use for them.

“There was a need for a recycling facility in our community,” explains Ledford, who has spent the last 18 years building and handling structural modifications to communications towers. “I wanted to do something where I was giving back and leaving things better than the way I found them.”

Ledford plans to add a horizontal grinder to his Georgia operation as a backup to the trommel.

Adding a new horizontal grinder can run from $500,000 and up. A stand-alone coloring system can cost anywhere from $125,000 to $250,000. Used equipment is available and may provide a lower cost option for a mulch producer wanting to get into the market.

Colorant can be added to both wood products (i.e. wood pallets and C&D materials) as well as mixed green waste, the latter which is has become the predominant source of material, according to a survey of 1,100 mulch producers.

Colorant equipment manufacturers include:

— AgriCoatings, a division of American Colors, Inc., markets both the Renegade and Orion systems which can convert existing equipment into an accurate colorizer, maximizing efficiency and reducing costs due to colorant waste. The Renegade offers variable throughput from 40 to 800 yards per hour.

— Amerimulch, offering the ColorTrom300 with its integrated Marksman technology to constantly measure the production rate and calculate the desired water and colorant application rates. Amerimulch, a business division of ChromaScape, also markets the MobileTrom, a self-contained, transportable unit.

— Bandit Industries, with its Beast horizontal grinders and optional Color Max colorizer system, which is designed to use less water and colorant to create rich, evenly colored mulch.

— BASF, featuring the Sahara X3 and Sahara Pro stand-alone coloring systems, both with a Global Equipment Management electronic control system that can provide a suite of reporting capabilities.

— Diamond Z, offering its liquid injection system, which sprays liquid colorant directly into the rotating valve of its grinders.

— Florida Coastal Color, which markets the V-Max 300 color unit and the CP-250 and CP-500 portable pump units that can convert any grinder or trommel into a coloring system.

— Greenwood Farms, offering the Color Critter G3 dry color dispenser as well as the Color Drum, a liquid color dispensing unit that fits any trommel-style screener.

— Mulch Manufacturing, which sells the heavy-duty Cheetah coloring system and the smaller Cheetah Cub, which can be moved or be operated as a portable unit. The company also is a mulch producer.

— Rotochopper, offering its patented grind and color system that features the company’s “perfect in one pass” technology.

— T.H. Glennon Co., with its compact and economical Mulch Color Jet coloring unit that can be added to existing mulch processing equipment.

— timber ridge equipment manufactures a self-contained mulch coloring system called the Chameleon, as well as individual coloring pumps that can be integrated with a grinder or trammel screen.

Justifying the cost for colorant can be easily made, with colored mulch typically selling for more than natural mulch, notes one industry expert.

“The cost for you to add colorant to mulch — whether it’s bagged or not bagged — is less than the diesel fuel used to deal with the mulch,” he says. “It’s less than the manpower. It’s less than the plastic bag that the mulch goes into. There are multiple areas that cost more than the colorant when it comes to coloring mulch.”

Adam Martin, owner of Martin’s Farm and Compost, says offering colored mulch has been a boon to his business. About two-thirds of the bulk mulch sold at his Greenfield, MA, facility is colorized, with the other one-third natural mulch, he reports.

“It’s improved my business,” Martin says of offering colored mulch since 2011. “It makes me more versatile with being a ‘one- stop shop.’ I get people coming in for compost and they see the colored mulch, and vice versa.”

Steve Condos of Metker-Ech, Inc., in Hartville, Ohio, echoes those sentiments.

“It (colored mulch) has increased our sales overall,” Condos says.

The following companies offer mulch colorant equipment as well as other products for the industry:

AgriCoatings

AgriCoatings offers the Renegade, a portable, accurate colorant pump injection system, and the Orion, its most advanced system, to transform a grinder, trommel, new or used coloring machine into an accurate colorizer. The Renegade features a 2-inch quick-connect manifold that utilizes a gate valve to control water flow that is read with a non-clogging water meter. The Renegade can be upgraded with a Human Machine Interface (HMI) unit that allows for more functions, such as automated control through an app on a smart device or the tracking of production data. The Orion uses a laser that scans mulch throughput. This information is communicated to the PLC which in turn regulates color pump speed and water flow based on parameters initially set by the user. This autonomous control allows for production of a more consistently colored product. The Orion and Renegade/HMI systems provide a way to collect accurate production data and colorant consumption information. AgriCoatings

Amerimulch

The ColorTrom 300 is described as a no-wear, low-maintenance system that can produce up to 350 color-enriched cubic yards of mulch per hour. Introduced in 2016, the system utilizes a newly designed colorant and water-spray delivery system that reduces water, colorant and energy. The ColorTrom 300 features a twin drive assembly without chains and gears resulting in lower maintenance. There are also no paddles or liners to replace, so uptime is maximized. A twin spray-bar assembly distributes water and colorant in two sections to reduce water application rates and provides a more concentrated application of colorants. The Marksman system integrates with the ColorTrom 300 to only activate the colorant pump when fiber is present to eliminate colorant waste in an empty drum. The ColorTrom 300 includes a bulk feed, low-profile hopper that holds up to 20 cubic yards. Amerimulch also offers the MobileTrom, a self-contained, transportable unit that can produce up to 120 cubic yards per hour. Amerimulch

Rotochopper

Rotochopper launched its patented grind and color system in 1997, allowing customers to simultaneously grind and color their wood waste into colored landscape mulch. The system injects water and colorant directly into the grinding chamber, using the force of the grinding process to thoroughly mix colorant into the wood fiber. The entire process is completely self-regulated and easy to adjust to match wood fiber consistency and mulch specifications. The colorant injection turns on automatically when raw material enters the grinding chamber and turns off when the grinding chamber runs empty, minimizing colorant usage and mess. The grind and color system is designed to lower handling costs and reduce colorant usage and spillage while producing colored mulch at the lowest cost per yard. Rotochopper has introduced its 2nd generation colorizer, offering what it calls its “perfect in one pass” technology. Rotochopper equipment is available in a wide horsepower range to match feedstock and product requirements. Rotochopper, Inc.
