FRSW
1775 Alison Blvd., Fredericton, New Brunswick, Canada

FRSW is a regional sanitary landfill in New Brunswick that bales its garbage. It also boasts a curbside blue and grey box recycling program in NB, and has a successful and popular office paper collection program. It operates a recycling facility – Materials Recovery Facility – and operates a household hazardous waste program each Wednesday and Saturday at its location at 1775 Alison Blvd. It also operates a landfill gas to energy system.

Solid waste brought to the landfill is disposed of in the most environmentally sensitive way possible. This starts with the construction of a cell to hold the waste. The landfill is located on land between two large drumlins of clay which is integral in landfilling. Clay acts as a natural barrier between garbage and the surrounding soil and water supply. We don’t let the clay do all the work, a geo membrane which has the consistency of a vinyl record, is also placed in the cell to act as another barrier between the waste and the surrounding environment. A cell is about one hectare in size.

Once a cell is completed, bales of solid waste are then placed into it. It takes about two years to fill a cell with garbage.

Environmental Protection :

Leachate is the liquid waste formed when rain and snow drain through the cells of a landfill. At the FRSW site, leachate is collected and piped to a biological treatment lagoon. Leachate is collected through pipes at the bottom of the cells and gravity pulls it to the lagoon.

Once the leachate reaches the lagoon, treatment begins. The first step is to encourage biological activity in the leachate through a specially designed oxygen injection system. Oxygen helps introduce microorganisms that eat away at the pollutants in leachate. The liquid stays in the lagoon and is treated for about 120 days.

After about four months of treatment, the leachate is piped to the City of Fredericton’s wastewater facility and treated again before being safely released into the environment. In addition to the leachate treatment lagoon, FRSW regularly monitors surface and groundwater at the site to ensure all environmental protection systems are functioning properly.
