Call for Papers: Biotechniques for Air Pollution Control

Background

In recent years, energy and feedstock materials for the chemical industry are in increasing demand. With constraints related to availability and use of oil, the energy and chemical industry is undergoing considerable changes. The need for the use of cheaper and widely available feedstocks, and the development of sustainable and environmentally friendly chemical processes is rapidly growing under both economical and public pressure.

Therefore, waste gas treatment has gradually been integrated into process design. Instead of discharging their waste gases into the atmosphere, industries increasingly attempt to become self-sufficient and recover compounds from their own wastestreams or use (upgraded) wastestreams of neighbouring industries as raw material.

Sustainable gas treatment concepts are under development, and can lead to the recovery of useful by-products like energy in the form of biogas, hydrogen or electricity, and chemicals in the form of e.g. fertilizers (ammonia, phosphates) or raw materials (elemental sulfur, sulfuric acid,...). Obviously, adding value to waste gas by upgrading the recovered compounds will only be a reality if it is demonstrated that there is a fundamental basis and a tangible advantage in using these recovered compounds rather than buying raw materials and feedstock.
