Biotechnology’s role in sustainable environmentConcern: novel behaviors, in some instances, may present a risk to human health or the environmentCertain uses assessed under TSCA

The Technology
Traditional mutation techniques inefficient, difficult to target to specific traits
Traits that enhance production or quality in other species can be identified and transferred through biotechnology
Yield increased, greater efficiency
Leads to new and improved end products

Categories of Biotechnology(for regulatory purposes)
Microorganisms have been employed by business, universities, and government to meet certain R&D and commercial needs for years
Majority of these applications are outside TSCA’s jurisdiction
