Landfill Gas to Energy Project – Aquatera

Aquatera, Bio-Reactor landfill, this is different then a normal landfill as the recirculating of the lechate back into the cell allowing for more rapid decomposition. This is the ASTM D5511-12 testing method. For more information in regards to the testing of ASTM D5511-12 please visit the Testing Methods Page. By 2013 the waste water of this township is because of landfill gas to energy produced from methane gas.

We, at Aquatera, are dedicated to our values. We want to make the place we call home, and do business in, a healthier place to live. It is with great pride that, beginning in 2013, Aquatera’s waste management facility, operating as a bioreactor landfill, will begin converting the landfill gas produced into energy. This innovative technology will allow Aquatera to not only reduce greenhouse gases. It will also supply the energy needed to power our water and wastewater treatment plants. Natural gas by our generators will supplement the landfill gas energy. At times, the generators may produce surplus electricity, which will be fed back into the electrical grid offsetting carbon-based energy.

The process begins with you. It begins with your waste, including organics, such as food waste and yard waste. All garbage collected are brought to our landfill, is compacted in layers in engineered landfill cells. Our landfill includes a layer of compacted clay, a plastic liner, and a geotextile mat. On top of this, is a layer of sand, tire shreds, and another layer of geotextile mat. Then, your garbage is compacted on top. Organic waste is quickly decomposable. Meaning, it breaks down at a faster rate than other waste. Because organics quickly decompose, they produce more landfill gas, and at the same time, free of space in the landfill for more waste. In our bioreactor, the fluid collected, called leachate, is re-circulated along with other fluids into the waste to enhance decomposition. Landfill gas created from decomposing waste will be collected through pipes drilled into, or laid in, the cells. Gas that is captured by the pipes is pumped to a generating station where all water is removed from the gas. And the gas, which is primarily methane, is burned. When the methane gas, which is twenty three (23) times more damaging to the ozone and carbon dioxide, is burned, it powers an engine that turns generators to make electricity. Our treatment plants will use our own electricity to continue to produce high quality tap water, and high quality treated wastewater for return to the river.

So, to recap, your household waste is transferred to the landfill. The waste, including organic waste, and all other garbage, decomposes, where its methane gas is harnessed by a generator, which powers the water treatment plants. That delivers fresh, clean drinking water back to your household, and high quality treated wastewater back to the river.

By using this method of generation, we, at Aquatera, reduce our environmental footprint enough that we generate carbon credits, which can be purchased by partner companies. This makes our company more efficient for our customers and more profitable for our shareholders. We, at Aquatera, are committed for always looking for new waste to make our company more innovative. With ideas like this, and future ideas, we are making changes necessary to keep Alberta beautiful.
