Small Business Start-Up Costs: A Prerequisite for Success

Every venture begins with a financial roadmap, and tire recycling is no exception. Before diving into the specifics of equipment, take the time to assess your small business start-up costs. Consider expenses such as permits, licenses, location, insurance, marketing, and operational necessities like transportation and labor. A start-up budget lays the groundwork for a profitable tire recycling business. The main start-up cost will be the machinery required to break down full tires into bite sized pieces or even rubber powder.

Why Tire Recycling?

Before exploring specific machinery options, it&#;s useful to delve into the more broad question of why. Why the rubber industry? Why recycling?

Discarded tires pose significant environmental threats, from feeding dangerous fires to creating breeding grounds for pests. Tire recycling not only stops these issues but also transforms used tires into valuable raw materials for various industries.

Some cunning entrepreneurs might think it wise to begin sourcing and stockpiling end of life tires before investing in equipment to ensure immediate returns. However, the risks of storing large piles of unprocessed tires makes this a potentially hazardous way to start. It&#;s best to invest in tire recycling equipment upfront.

What equipment will you need?

1. Shredders: The Heart of Tire Recycling

Tire shredders play a pivotal role in the initial stages of tire recycling, breaking down whole tires into manageable pieces. Shredders usually rely on gravity to assist in the process. Thus, tires need to be lifted by a mechanical arm or conveyor belt to the right height. High-quality shredders are versatile, accommodating various tire sizes and types, such as off-road tires or tractor tires. Before purchasing a shredder, consider its processing capacity, durability, and maintenance requirements. These characteristics directly influence how much you can produce per day.

2. Granulators: Refining the Output

Granulators pick up the shredded tires and refine the rough pieces into uniform bits called granules. These granules are the foundation for creating a range of products, from rubberized asphalt to molded rubber goods. Look for granulators that offer precision and consistency in the shredding process. How pure your granules are directly determines how much they are worth in the market.

3. Crumb Rubber Systems: From Marbles to Sand

Crumb rubber machines take granules a step further, producing high-quality crumb rubber or rubber powder. This versatile material serves as a raw ingredient for countless marketable products, including athletic surfaces, construction materials, and high-quality asphalt.

4. Pyrolysis Equipment: Transforming Tires into Oil and Gas

Pyrolysis is an innovative approach that involves heating tires in the absence of oxygen to produce oil, gas, and carbon black. This method offers an alternative route for tire recycling, generating valuable resources for various industrial applications. This equipment can be costly, but the outputs are very profitable. It&#;s impressive how junky tires can seemingly turn to gold with the right system in place.

5. Profitable Add-Ons: A Splash of Color

Add-ons to a recycling line can elevate the versatility and marketability of the end products. One notable enhancement is the incorporation of a colorizing machine, which allows tire recyclers to produce vibrant and aesthetically appealing rubber materials. This technology opens opportunities for creative applications in playground designs as well as meeting specific market demands for specific colors in architecture.

Mold machines are also valuable add-ons, enabling tire recyclers to shape rubber materials into various forms and sizes. For example, you could produce plugs, toys, tiles, and mats. By integrating these add-ons into a tire recycling line, businesses can diversify their product offerings and meet niche market demands.

Finding the Right Fit

As you navigate the tire recycling machinery maze, remember that the success of your venture hinges on choosing the right equipment for your target output. Assess your business&#;s specific selling points. In general, recyclers earn more if they are high quality. Consider factors like processing capacity and technological advancements.

Tire recycling equipment manufacturers like Eco Green offer tire-specific equipment, while others offer general processors. Some machines have a more significant environmental impact themselves, negating the good they are doing, while others are more efficient. Like any big purchase, the best advice is to explore a range of equipment options. By making informed decisions, you can get the recycling line running effectively and reliably.

Tire recycling is a promising sustainable business venture that combines environmental awareness with practical inputs and outputs. As an entrepreneur, it&#;s important to grasp the details of the tire recycling process and select the appropriate equipment. Explore the five tire recycling machines in this infographic.

Tire grinding for recycling was first developed in Minnesota in . It began as a mechanical process to break down the tires and separate the useable rubber from the metal and fabric components of the tire. Similar to the way an office paper shredder destroys documents, these shredders cut the rubber into smaller pieces. By weight, a typical tire is 70% recoverable rubber. The rest is steel, fibers, and fillers. When recycled, a standard passenger tire will yield 10-12 pounds of rubber after filtering out the other materials.

Regardless of the final method used, all three primary grinding processes start the same way. Mechanical, ambient temperature grinding is the only method that can take a full-size tire and break it down into smaller pieces that can be fed into other machinery for further processing. After this initial break down step, there are three primary grinding methods that tire recyclers use.

1. Ambient temperature grinding &#; the first method developed, this type of grinding is the most common. It is a multi-step process using a series of granulators and cracker mills interspersed with magnets (to remove steel) and air separators (to remove fibers). These machines can process the rubber from large pieces down to crumb rubber that is 20-30 mesh or 600 microns in size.
2. Micro milling &#; a wet process, usually using water, that can grind rubber much smaller than traditional methods (40 mesh and smaller). Because the rubber is ground in fluid, usually water, it produces a clean, washed product. This process, however, is patented and can only be used by those who own rights to the patent.
3. Cryogenic grinding &#; starting with rubber that has been coarse ground to two-inch minus, it can produce a fine grind, ¼ inch minus to 30 mesh, in fewer steps at a rate of 4,000-6,000 pounds per hour. In this method, liquid nitrogen is used to freeze the rubber, which is then &#;shattered&#; as it passes through a hammer mill. At temperatures well below freezing, the rubber breaks along smooth lines giving the surface a much more uniform texture.

Each grinding method requires different equipment and materials and produces a slightly different product, giving each advantages and disadvantages. The process that is best to use is the one that will provide the product that the customer wants. In many cases, contractors may not care as much about the type of rubber that they are buying as they do about its cost.

While most recycled rubber still ends up as tire derived fuel, another major product is crumb rubber. Crumb rubber consists of rubber that has been ground down to 3/8 inch or smaller.

What are the differences in ambient and cryogenically ground rubber crumb?

The biggest difference is the shape of the individual pieces of rubber that are produced in each method of grinding.

When rubber is ground at ambient temperatures, it still maintains the characteristics of rubber. Being somewhat pliable as it passes through the shredders, the edges of the cuts are rough. These rough edges affect the properties of the rubber. For example, for use in Rubber Modified Asphalt, ambient cut crumb rubber is preferred. The rugged edges of the rubber crumb give it more surface area to bond to the asphalt with which it is mixed.

When using the cryogenic process, recyclers spray the rubber or submerge it in liquid nitrogen. At temperatures below -112F, the rubber no longer acts like rubber. It acts more like glass. When hit in the hammer mill, the rubber shatters along smooth, straight lines.

These smooth particles that appear shiny are less prone to hold air bubbles when submerged in water. These particles are also better for mixing with sand as infill. They form a more stable connection and foundation with the silica sand. For this reason, cryogenically ground rubber is preferable for use in athletic fields. When rain falls on the artificial turf, ambient ground rubber has a tendency to float and move around in the water. This movement can create an uneven playing surface that may even contain potholes, creating a dangerous situation for players using the field.

Cryogenic grinding comes at a cost, however. Liquid nitrogen, while common and easily attainable, can cost a recycling company 2 to 6 cents per pound of rubber, depending on the desired rubber particle size and the quantity purchased.

Which rubber crumb is best?

With the many varied uses of rubber crumb, it is clear that no one grinding method is best for every situation. For many companies and applications, the best product will be the one that is the cleanest, highest quality rubber that fits in the project budget. There are not currently industry standards governing rubber crumb quality. However, there are the key components to look at when determining the best crumb rubber for any job. Rubber with low metal, fiber and moisture content is best.
