The LSU AgCenter’s W. A. Callegari Environ­mental Center plays a vital role in meeting future domestic energy needs. It produces alternative, renewable fuels as part of its waste recycling and waste minimization program to help Louisiana and the nation meet new clean air standards.

As part of the AgCenter’s bioenergy research program, the Callegari Center plays an active role in developing alternative fuels such as biodiesel. The center features a biodiesel plant that’s used in conjunction with established labora­tory procedures to characterize bio­diesel and evaluate quality control procedures.

Along with traditional food crops such as corn, soybean, sugarcane, sorghum and sunflowers, sci­entists are evaluating non-food crops such as rape seed, Chinese tallow and palm oil as feedstocks for biofuels. The center is producing biodiesel from used vegetable oil from LSU campus food service operations. This fuel will be blended with petroleum-based diesel fuel for use in heavy equipment and transportation vehicles.

The entire process of converting used veg­etable oil into biodiesel can serve as a “living classroom” for communities across Louisiana. The center will be a source of information for entrepreneurs and small businesses that want to learn about biodiesel production and be a real-world laboratory for engineering and chemistry students at LSU.

Biodiesel has significantly lower emissions com­pared with petroleum-based fuels. Converting biomass into fuel improves the environment, and including used vegetable oils diverts these waste materials into useful products.

Biomass-derived fuels produce financial benefits of fuel savings, disposal savings, employment opportunities and environmental improvements. Besides transportation, biofuels can replace other fuel sources for such uses as heating and electri­cal generation.

The center’s laboratory capabilities include instrumentation, measurement and data analysis to test biodiesel for quality assurance and qual­ity control according to ASTM methods. They include:

• Shelf life of biodiesel.
• Quality measures regarding different processing techniques
• Options for the use and re-use of byproducts, mainly glycerin and methanol
• Evaluation of various sources of plant feedstocks
• Methods for improving fuel and byproduct quality

The W.A. Callegari Environmental Center is the LSU AgCenter’s research and training facil­ity for composting organic waste and for water and air quality. Located on an 8-acre site on the Central Research Station south of Baton Rouge, the Callegari Center serves researchers, agricul­tural producers, private companies, governmen­tal agencies and the general public in the areas of composting, water quality, air quality and bioenergy.
