The National Biodiesel BoardThe National Biodiesel Board

Represents the biodiesel industry as the coordinating body for research and development in the United States. 

Today NBB’s membership is comprised of state, national, and international feedstock and feedstock processor organizations, biodiesel suppliers, fuel marketers and distributors, and technology providers.

Official IRS and EPA definition – goes to the legal definition and to fuel quality.

Biodiesel, n. -- a fuel comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats, designated B100, and meeting the requirements of ASTM D 6751.

Emissions & HealthEmissions & Health

MSHA (US Department of Labor – Mining Safety and Health Administration) recognizes biodiesel as the least expensive means for reducing underground worker exposure to DPM – this is a direct worker health issue

Fuel Quality & StandardsFuel Quality & Standards

Industry-wide Fuel Quality Program BQ-9000 (www.bq-9000.org) Insures for “supply-chain management” (from feedstock

through fuel use)

ASTM Specifications exist for: B5 and lower

B6 to B20

B100 (ASTM D 6751-09)

Accredited Producer Focus

A system for monitoring the production of biodiesel to the ASTM D 6751 specification.

BQ-9000 Quality Management Program

The latest numbers show that about 81% of biodiesel produced is by BQ-9000 accredited companies.

BQ-9000 Quality Management Program

The program continues to grow as there are currently 4 new companies who recently completed their initial audits.

All major U.S. OEMs support at least B5 and lower blends, provided they are made with biodiesel meeting ASTM D 6751

Most OEMs recommending use of BQ-9000

More than 55% of U.S. manufacturers now support B20 or higher blends in at least some of their equipment

Several more OEMs completing testing toward B20 support
