What are fuel cubes?
Balcones Fuel Technology fuel cubes are a blended mixture of combustible materials. These materials are shredded and then extruded through dies under extreme pressures to form small cubes approximately 1" x 2" in length.
What are the chemical and physical characteristics of your fuel cubes?
The predominant materials in Balcones fuel mix are cellulose fiber and polypropylene plastic.
What type of furnace configurations can burn your fuel cubes?
Balcones fuel cubes have been successfully burned in several different furnace configurations, including rotary kiln, gasifier and traveling-grate stoker-spreader boilers.
Are there any mechanical or environmental problems associated with burning Balcones fuel cubes?
Balcones has performed extensive research and testing in the development of its fuel technology. We have not found any operational or mechanical problems. In addition, no pollution abatement process upsets or excursions above regulatory permit levels were observed during fuel cube usage.
What is the average heat of combustion?
12,400 to 13,500 BTU per pound
Do you accept new sources of raw feedstock for the manufacturing of your fuel cubes?
Yes, however all new materials must go through rigorous testing to confirm their compatibility. We cannot accept any materials that will substantially lower the BTU values or change the desired handling, burn or environmental characteristics of our existing fuel.
How are fuel cubes shipped?
Shipping depends on the end user. We can ship by truck or rail. There are no special requirements.
Q. I noticed the janitorial staff here pouring my recyclables into the regular trash; can you explain how they sort our materials?
A. We hear this frequently.  Balcones Resources takes pride in the training that we provide to all janitorial staffs. Although mistakes may happen, here are a few reasons to explain this issue:
  • The janitorial staff may use the "double bag" collection method. This means that there are actually dual bags inside of their cart, and although it may appear that all of the materials are going into the trash, it is being separated.
  • There may have been a food item in the recycle bin that prompted the trained janitorial staff to follow our protocol and keep those items out of the recycling stream.
  • Keep in mind that we only get compensated if there is a strong recycling stream present in the building. We monitor all waste streams to make sure the recycling levels are consistent. If there is a decline in the tonnage or notable contaminated materials present regularly, we are onsite to conduct additional training. 
  • If you still have concerns that anyone at your facility is abusing the recycling program, please notify your property or facilities manager for resolution.
Q. Are used pizza boxes accepted?
A.  No. Here's why: Food is one of the worst contaminants in the paper recycling process. Grease and oil are not as big of a problem for plastic, metal and glass, as those materials are recycled using a heat process. But when paper products, like cardboard, are recycled, they are mixed with water and turned into slurry. Since we all know water and oil don't mix, the issue is clear. Grease from pizza boxes causes oil to form at the top of the slurry, and paper fibers cannot separate from oils during the pulping process. Essentially, this contaminant causes the entire batch to be ruined.
Q. Can I leave the lids on plastic bottles?
A. Yes. The lids to plastic bottles are made of different grades of plastic than the bottle itself. These are recyclable and are removed through a flotation method during the recycling process.
