4. Bioremediation

Today environmental pollution is a universal problem because of uncontrolled population growth and fast industrialization and urbanization in the world. Contaminated environment needs to be cleaned by appropriate remediation techniques for ecological balance. Currently used environmental cleaning applications mainly involve conventional remediation techniques. New advancements in biosciences and biotechnology allow development of highly effective new and sustainable remediation techniques. It is expected that most of the conventional environmental cleaning techniques will be replaced successfully by sustainable bioremediation techniques in near future.
