Garbage In- Garbage Out
This should be the mantra of every BioCube user. The Biocube can create extremely high quality fuel and has met international compliance standards in numerous trials and tests. However, the quality of output biodiesel produced is invariably determined by the quality of the feedstock oil put in. The onus for managing the quality of that incoming feedstock oil lies squarely on the shoulders of the operator. Simple quality control, titration and management of feedstock will alleviate many issues.
Not all oils are created equal
The BioCube is largely feedstock agnostic, and there is a large variety of feed stocks available. Certain oils lend themselves extremely well to the process of trans esterification. Others do not. It is simply impossible to create high quality diesel from certain oils (Castor) yet soy, palm, canola, cottonseed, pongamia and jatropha are highly suitable. Feedstock availability, selection and quality is a key determinant on the final fuel quality of the BioCube.
Pre and Post treatment
To create the best conditions for good diesel the BioCube requires oil over a certain standard. These standards relate to particulate and water content, free fatty acid (FFA) levels and filtration. To fulfill some of the criteria related to international biodiesel standards compliance, post treatments and additives need to be introduced. BioCube will be happy to guide the customer on these issues, and where possible have created ancillary processes to rectify any comings in feedstock oil. As not all users will need these they are not a part of the standard equipment of the BioCube.
International biodiesel standard compliance
There are a number of different international standards for biodiesel compliance. BioCube Corporation uses ASTM D6751 as it is arguably the most widely accepted benchmark standard. The standards for B100 compliance are extremely exacting, with compounds measured to one thousandth of a percentage point (.001%). As such, your biodiesel could fail the ASTM test by one part per thousand. This does not mean the fuel is less usable in your diesel generator, only that it does not meet this very strict measure of fuel standard. The BioCube has met these rigourous standards and if the owner sets the BioCube up for success with quality oil and chemicals and is careful in their collection protocols, their BioCube will also be able to meet the standard.
