Cleaner Options for Sustainable Energy

Sustainability is a major buzzword in business today, but what does it mean for energy production and waste disposal? On the production side of the equation, one major initiative being undertaken in the industrial field has been using common by-products as a source of fuel (biomass). This waste-to-energy conversion not only results in a cleaner environment, but also represents an opportunity for renewable and sustainable energy development.

On the waste side of the picture, sustainability can mean finding ways to make the byproducts of energy production cleaner.  For both biomass and coal-fired power plants, the necessity for cleaner energy has been made even more apparent, thanks to the Mercury and Air Toxics Standards (MATS) regulation. The new standards limit emissions of mercury (Hg), hydrochloric acid (HCl), and filterable particulate matter (fPM) from power plants to benefit public health. They also regulate SO2, SO3, and HF emissions.

Mercury and hydrochloric acid in particular are well-known by-products of coal-fired plants, as well as from biomass fuel, creating a need for better options in this industry.

Dry sorbent injection (DSI) is one method ideally suited to aid in pollution mitigation of all these requlated emissions. It neutralizes harmful gases before they have a chance to be released into the atmosphere. This is a major step forward in the power generation field.
