Power
Our company principals have been working with power companies since the mid-1990s, primarily associated with the design and permitting of industrial solid waste landfills for coal combustion by-products (or coal ash). Based on our success with these projects, we aim to pursue an extensive range of environmental issues. Today, we provide various environmental engineering services supporting the management of coal combustion by-products for power plants.
Coal Ash Pond Evaluations & Ash Landfills
Historically, power companies have managed coal combustion by-products (or coal ash) through a series of coal ash sluicing ponds. Today, several factors are driving power companies to re-think this approach and consider dry handling. These factors include capacity limitations, groundwater regulatory changes, and air quality regulatory changes.
Flue Gas Desulphurization (FGD) Scrubbers
Scrubbers are used in U.S. power plants to achieve emissions standards set by the U.S. Environmental Protection Agency (EPA). New regulatory programs call for further reduction of sulfur dioxide (SO2) emissions from coal-burning power plants. Flue gas systems frequently use limestone-forced-oxidation scrubbers to convert SO2 in flue gas to gypsum, which can be sold for wallboard manufacturing, cement additive, or agricultural applications, thus developing a waste stream into a usable resource. Landfills are necessary for the disposal of the gypsum by-product when demand for the gypsum falls short of the production.
Green Power
Garrett & Moore has developed partnerships in which we assist with project development and management of several unique green power technologies. These partnerships have led to two landfill gas to energy projects. In addition, we have a relationship with ArrowBio, who is on the forefront of using solid waste and converting it to fertilizer and biogas through anaerobic digestion.
