Here at Piedmont Biofuels we run a specialized biodiesel production quality control laboratory.

Often we consult with others that are building biodiesel plants or working on perfecting their current process for new equipment or variations in catalyst or feedstock. If you are looking for assistance in either quality control or process adjustments, we can provide analytical support.  We usually have a 3 day turnaround once the sample is recieved.

At Piedmont Biofuels, we can evaluate certain biodiesel feedstocks for their suitability for various biodiesel production technologies. We have worked with a variety of feedstocks including but not limited to: virgin oils (soybean, canola, palm, peanut, sunflower, cottonseed), animal fats, yellow and brown greases. A feedstock performance analysis will include our initial feedstock analysis in addition to a lab scale processing to determine reaction capability and process performance.

Currently we have the analytical capability to test several of the ASTM standards for Biodiesel D6751 in addition to AOCS (American Oil Chemist Society) methodology for fats and oils and European test methods for biodiesel

Piedmont Biofuels’ Bio-refinery operations includes analytical capabilities to process and determine the quality of crude biodiesel glycerin. If you want to better understand the co-product of your biodiesel process, send us a sample.

We have also worked with many customers on individualized testing and analysis which are not included here.  Call us and put our knowledge to work for you.

How do I submit a sample for testing?

1) Fill out this form.  Print a copy and include the copy in the sample package.

2) Package the required amount of sample and send it to the address below.  Samples should always been properly sealed and packaged – meaning containers with tight lids sealed with tape, all contained inside at least one sealed plastic bag in case of spills.  Also, samples should be clearly labeled in multiple locations with sample name and sample type (crude biodiesel, finished biodiesel, glycerin, etc.).
