Power your world with sustainable practices. Cat® generators for landfills are designed to collect, clean, and run on harmful gases produced by landfills. It’s reliable power that can reduce your environmental impact.
Sell the power produced to your electric utility with our switchgear, including programmable logic controller (PLC) based controls, paralleling your generators to the local grid.
Our expert team is dedicated to getting you started and keeping you running — to keep your business sustainable and successful.
Modern landfills are required to install gas collection systems to capture and destroy the methane gasses that are naturally produced within a landfill. These gases are burned in a flare. Rather than eliminating landfill gas by simply burning it off, Caterpillar can help you turn it into a renewable fuel by providing gas-fueled engine-generators that can produce electric power from landfill gas.
With today's focus on renewable energy and carbon emissions reductions, landfill-gas-to-energy projects are gaining momentum. These applications use Cat generators to turn waste into economically viable electricity. Caterpillar continually researches, develops and delivers landfill gas products specifically designed to be operated on landfill gas fuels.
Cat generators for landfills are designed to:
Landfill gas is produced naturally as organic waste decomposes in landfills. It is composed of methane, carbon dioxide, and small amounts of non-methane organic compounds. As an important and growing application within the world's power generation mix, landfill-gas-to-energy systems collect, process, and treat this gas for use in generating electricity. Two common approaches to landfill gas collection include vertical well extraction and horizontal collectors or trenches.
Municipalities generally use blowers or vacuums to direct the gas from a collection site through a network of pipes to a central facility. At most developed municipal solid-waste landfills, the methane and carbon dioxide are destroyed in a gas collection and control system or utility flare. The sustainable alternative is to divert the landfill gas from the flare to be used in electricity-producing Cat generators.
The diverted fuel is dried and sometimes refined to remove impurities such as:
After fuel treatment, the methane is introduced into a Cat gas generator as fuel. These generators are specifically designed for operation at landfills with:
Cat switchgear with PLC-based controls is supplied to parallel the generators to the local electrical grid to export renewable power at a premium to the local electric utility.
