Product Technology

The Product Technology Study Group is concerned with the study of processes and procedures relating to tobacco processing and manufacturing facilities and with the description of tobacco and tobacco products in terms of physical properties, chemical properties and quality. The Study Group also works on electronic cigarettes. Study Group activities include development of analytical methods for the determination of product properties, monitoring of engineering techniques and developments in tobacco processing, product manufacturing and environmental protection.
