The Leader in Tire Recycling
Our recycling technology begins with the separation of used tires into their constituent parts of steel, fabric and rubber. The tire rubber pieces are then processed into crumb rubber.
BAS Recycling, Inc. offer a complete solution to the used tire solid waste problem with the collection and recycling of tires generated by tire dealers, tire manufactures, tire retreaders, and many public agencies
High Quality Crumb Rubber
The crumb rubber produced is continually inspected to insure quality and is available in a wide range of gradations that is uniform, consistent, and contaminate free. Surface treated and custom matrix blended materials are statistically tested to insure consistant, quality engineered mate


Raw Material For All Rubber Products
The crumb rubber material is produced to gradations suitable for incorporation into rubber mixes using conventional rubber mixing equipment. The resultant mixtures can be molded or extruded depending on application. Our technical staff is available to work with your requirements to develop a custom blend of crumb rubber engineered to specific requirements and available in both a surface treated or untreated material

Low Cost Engineered Materials = Increased Profits
Why is crumb rubber from whole tire recycling suitable for inclusion in your process or product line? The answer is very simple. Reduced Production Cost; using our low cost engineered materials results in increased manufacturing profits. A lower cost alternative to virgin materials, with their skyrocketing prices, allow a price competitive advantage in both new product development and existing product l

GroundRubber Horse Arena Cover is a unique rubber product that offers one of the safest and most resilient footings available for horses. GroundRubber can dramatically enhance the performance and comfort of your horses, and is appreciated by Dressage and Hunter Jumpers alike. GroundRubber is also odorless, and requires less watering and dragging than other footing products.

GroundRubber may cost a bit more initially, but it has a virtually unlimited lifespan, compared to other surfaces. It only needs to be installed once, it doesn't wash away, and is extremely cost effective to maintain.

GroundRubber has been shown to absorb much more impact than sand, shavings and mulch products. It effectively reduces the repeated concussion horses sustain from being ridden on hard surfaces, enabling them to perform at their best.
GroundRubber stall mats offer all the same benefits as the Horse Arena Cover with the advantage of being very easy to clean. This soft, durable surface provides more than enough cushioning support for your horse, and significantly reduces the need for stall bedding. You will virtually eliminate mucking and digging, saving time and money.






Preparation, Installation & Maintenance
Prior to GroundRubber being installed in horse arenas, the **** should have 4-6 inches of crushed and compacted stone to the hardness of asphalt. Next sand should be added to assure proper depth, followed by GroundRubber. Finally drag the arena to insure complete mixture of the GroundRubber and sand.

To determine amount of GroundRubber needed, measure length x width to give us the square footage. Divide by 900 for a 1" depth, divide by 600 for 1 1/2" depth. GroundRubber can be added to an existing arena at anytime.

Additionally frequent dragging of an arena can greatly extend its life span. Frequency of dragging is determined by the footing and amount of use the arena gets.

SLIDE TILES
GroundRubber slide tiles are 36" x 36" molded rubber mats designed to be installed in front of playground slide exits or under swing sets. These 5" thick tiles are safety tested to a fall height of 5 feet.

Besides providing a slip-resistant safety surface, Groundrubber slide tiles are also easy to install and maintain, and come in several different colors. We recommend also using GroundRubber Playground Cover as loose fill material to comply with ASTM stand



GroundRubber wheel stops are lightweight, durable and easy to install in 3' or 6' lengths. Being made of rubber, they can absorb and redistribute impact, and reduce risk of damage to vehicles or property when parking. They also last longer than conventional concrete wheel stops and they are virtually maintenance free. Wheel stops are available plain or with yellow, blue or white reflective safety stripes


ANTI-FATIGUE MATS
GroundRubber anti-fatigue mats are very practical in workplace environments that involve long periods of standing, such as assembly lines, workshops, or food service. These mats provide much-needed cushioning comfort, reduce fatigue, and improve productivity for your employees. The non-skid surface is impact and chemical resistant. The underside has protruding nubs which enable air circulation and keeps the floor dry. Anti-fatigue mats are fully washable and easy to maintain, and can be cut to specific dimensions

Whole Tires

A typical scrapped automobile tire weighs 9.1 kg (20 lb). Roughly 5.4 kg (12 lb) to 5.9 kg (13 lb) consists of recoverable rubber, composed of 35 percent natural rubber and 65 percent synthetic rubber. Steel-belted radial tires are the predominant type of tire currently produced in the United States.(2) A typical truck tire weighs 18.2 kg (40 lb) and also contains from 60 to 70 percent recoverable rubber. Truck tires typically contain 65 percent natural rubber and 35 percent synthetic rubber.(2) Although a majority of truck tires are steel-belted radials, there are still a number of bias ply truck tires, which contain either nylon or polyester belt material.

Slit Tires

Slit tires are produced in tire cutting machines. These cutting machines can slit the tire into two halves or can separate the sidewalls from the tread of the tire.

Shredded or Chipped Tires

In most cases the production of tire shreds or tire chips involves primary and secondary shredding. A tire shredder is a machine with a series of oscillating or reciprocating cutting edges, ****** back and forth in opposite directions to create a shearing motion, that effectively cuts or shreds tires as they are fed into the machine. The size of the tire shreds produced in the primary shredding process can vary from as large as 300 to 460 mm (12 to 18 in) long by 100 to 230 mm (4 to 9 in) as wide, down to as small as 100 to 150 mm (4 to 6 in) in length, depending on the manufacturer, model, and condition of the cutting edges. The shredding process results in exposure of steel belt fragments along the edges of the tire shreds.(3) Production of tire chips, which are normally sized from 76 mm (3 in) down to 13 mm (1/2 in), requires two-stage processing of the tire shreds (i.e., primary and secondary shredding) to achieve adequate size reduction. Secondary shredding results in the production of chips that are more equidimensional than the larger size shreds that are generated by the primary shredder, but exposed steel fragments will still occur along the edges of the chips.(3)

Ground Rubber

Ground rubber may be sized from particles as large as 19 mm (3/4 in) to as fine as 0.15 mm (No. 100 sieve) depending on the type of size reduction equipment and the intended application.

The production of ground rubber is achieved by granulators, hammermills, or fine grinding machines. Granulators typically produce particles that are regularly shaped and cubical with a comparatively low-surface area. The steel belt fragments are removed by a magnetic separator. Fiberglass belts or fibers are separated from the finer rubber particles, usually by an air separator. Ground rubber particles are subjected to a dual cycle of magnetic separation, then screened and recovered in various size fractions.(4)

Crumb Rubber

Crumb rubber usually consists of particles ranging in size from 4.75 mm (No. 4 sieve) to less than 0.075 mm (No. 200 sieve). Most processes that incorporate crumb rubber as an asphalt modifier use particles ranging in size from 0.6 mm to 0.15 mm (No. 30 to No. 100 sieve).

Three methods are currently used to convert scrap tires to crumb rubber. The crackermill process is the most commonly used method. The crackermill process tears apart or reduces the size of tire rubber by passing the material between rotating corrugated steel drums. This process creates an irregularly shaped torn particle with a large surface area. These particles range in size from approximately 5 mm to 0.5 mm (No. 4 to No. 40 sieve) and are commonly referred to as ground crumb rubber. The second method is the granulator process, which shears apart the rubber with revolving steel plates that pass at close tolerance, producing granulated crumb rubber particles, ranging in size from 9.5 mm (3/8 in) to 0.5 mm (No. 40 sieve). The third process is the micro-mill process, which produces a very fine ground crumb rubber in the size range from 0.5 mm (No. 40 sieve) to as small as 0.075 mm (No. 200 sieve).(4)

In some cases, cryogenic techniques are also used for size reduction. Essentially, this involves using liquid nitrogen to reduce the temperature of the rubber particles to minus 87oC (-125oF), making the particles quite brittle and easy to shatter into small particles. This technique is sometimes used before final grinding.(5
