The Importance Of Emerging Biobased Industries To Engineering And Technology, Kurt A. Rosentrater, R. Balamuralikrishma Oct 2006

The Importance Of Emerging Biobased Industries To Engineering And Technology, Kurt A. Rosentrater, R. Balamuralikrishma

Kurt A. Rosentrater

Our society has developed an insatiable demand for energy and material goods. Historically, these needs have been met primarily by fossil fuels and other non-renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines the emergence and importance that biobased industries are increasingly beginning to play. A biobased enterprise, similar in concept to a traditional refinery or factory, utilizes conversion technologies to produce various products. These operations are rapidly increasing both in number as well as in capacity throughout this country, and are poised to add significantly to the nation’s energy and ...


Characteristics Of North American Meat & Bone Meal Relevant To The Development Of Non-Feed Applications, Rafael A. Garcia, Kurt A. Rosentrater, Rolando A. Flores Jul 2006

Characteristics Of North American Meat & Bone Meal Relevant To The Development Of Non-Feed Applications, Rafael A. Garcia, Kurt A. Rosentrater, Rolando A. Flores

Unmarketable animal tissues are typically processed by rendering plants, which transform them into meat & bone meal (MBM) or similar products. MBM’s traditional use as animal feed has become increasingly threatened, but MBM has potential for non-feed applications. Development of new products and processes is hindered by lack of reliable data on many of MBM’s chemical and physical properties. MBM samples as well as data on raw material and process were collected from 19 rendering facilities in the United States and Canada. A large majority of the raw material was tissue from cattle, swine and poultry. All facilities surveyed practiced continuous dry rendering; 89% of the facilities use continuous cookers and 11% use falling film evaporators. MBM is high in protein (44.6-62.8%, mfb), but this protein is poorly soluble; at pH 7 solubility ranged from 2.20 to 7.22 %. Among all samples, the particles’ median geometric mean diameter was 387 µm, and the size distribution was broad. The median density of MBM particles was 1.41 (g/ml); median density of MBM in bulk ranged from 0.50 g/ml when loose-filled to 0.68 g ...


The Global Relevance Of Bio-Based Industries To Engineering And Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma Jun 2006

The Global Relevance Of Bio-Based Industries To Engineering And Technology Education, Kurt A. Rosentrater, Radha Balamuralikrishma

Kurt A. Rosentrater

The society in which we live has developed an insatiable demand for energy and material goods. In particular, recent data reveals that the aggressive pursuit of improved standards of living in the highly populated countries of India and China has contributed to increased demand for fossil fuels, which has exacerbated the recent spike in energy costs. Historically, these needs have been met primarily by fossil fuels and other non-renewable raw materials. As environmental concerns grow, however, renewable resources are gaining increased attention. This paper examines the emergence and importance that bio-based industries are increasingly beginning to play. A bio-based enterprise ...
