The styrian technology behind the waste-based biodiesel production

8. August 2018 // All topics, News,

During the last decades, the BioDiesel production is focussing even more on the use of residuals and waste-based resources. The benefits of this high-quality biodiesel ranges from unique GHG reduction over permanent savings on sewage maintenance to a reliable withdraw of problematic organic material from the food chain. There are many examples of how evolving technologies made it possible to redefine waste as a resource, e.g. trap grease that was previously considered useless. With its patented Multi-Feedstock technology, BDI has the know-how to produce environmental friendly and valuable BioDiesel from a variety of raw materials, that exceeds the most stringent quality standards worldwide

In 1994 Graz became one of the first cities to establish a collection of Used Cooking Oil (UCO) from households and restaurants. The nearby SEEG biodiesel plant, built by BDI (BioEnergy International) was the first plant world-wide to process UCO in industrial scale. From then on thousands of tons of fat waste were transformed into biodiesel every year. To close the recycling management, the bus fleet of the public transportation switched to UCO based biodiesel.

The awareness to avoid used cooking oils and fats in the canalization increases – waste recycling becomes more important in big cities all over the world.

But what is the story behind this scene?

The most prominent example in the recent media coverage is the huge and bizarre 130tons fatberg in London. This fatty clump contains diapers and used cooking fat – nothing you should dump into the sewer. This fatberg could have been prevented by the establishment of a waste collection system.

The UK based company Argent Energy uses BDI equipment and is capable of converting even challenging resources into biodiesel according to EN standards.

What are the next steps?

BDI is currently working on interesting projects in America:
The company Crimson Renewable Energy is realizing the potential of the fat collection as well – they collect waste fats in the metropolitain areas of California, particulary in Los Angeles. BDI is providing once more the technology: The reuse of the catalyst, which is synthesized on-site, is one of the main characteristics of the RepCat process. It is only possible because this special catalyst is not sensitive to feedstock impurities or other usual troubles like catalyst poisoning.
